First RS model in the Q series: Audi RS Q3
Neckarsulm – Audi is presenting the RS Q3 at the Geneva International Motor Show, the first RS model for the successful Q line-up. It combines outstanding everyday practicality with dynamic driving performance: It takes just 5.5 seconds to complete the sprint from 0 to 100 km/h (62.14 mph), and its top speed is electronically governed to 250 km/h (155.34 mph). The 2.5-liter five-cylinder turbo produces 228 kW (310 hp) and has an average fuel consumption of just 8.8 liters of fuel per 100 km (26.73 US mpg).
“The RS Q3 transfers the performance philosophy of Audi to the compact SUV segment, thereby creating a new performance class,” says Franciscus van Meel, Managing Director of quattro GmbH. “In addition to the RS 5 Cabriolet, RS 6 Avant and RS 7 Sportback, the RS Q3 is the fourth RS model that we are launching on the market in 2013. The RS family is growing to eight members – more than ever.” The RS Q3 combines typical RS properties such as high performance and driving pleasure with lifestyle qualities and high utility value. The Audi RS Q3 was developed by quattro GmbH which is a wholly-owned subsidiary of AUDI AG.
An award-winning high-performance engine, the 2.5 TFSI, is at work under the hood of the RS Q3. This five-cylinder engine has been named “International Engine of the Year” in its class for three consecutive years since 2010 by an international jury of automotive specialists. From 2,480 cc of engine displacement, the turbocharged direct-injection engine produces a maximum power of 228 kW (310 hp) at 5,200-6,700 rpm; its maximum torque of 420 Nm (309.78 lb-ft) is available between 1,500 and 5,200 rpm. These two values signify that the RS Q3 is unrivaled in its competitive field. This five-cylinder is a special engine, beginning with its fundamental concept. It is familiar from the TT RS and RS 3 Sportback, and quattro GmbH modified it for use in the RS Q3. The 1-2-4-5-3 ignition sequence, supported by the geometry of the air induction and exhaust systems, generates a sporty engine sound that first made Audi popular back in the 1980s.
Drivers can influence the flap control for the exhaust system and the accelerator characteristic by choosing one of the modes auto, comfort and dynamic using the standard Audi drive select system. In the dynamic mode, engine response is sharper and the engine sound more intensive.
The 2.5 TFSI accelerates the Audi RS Q3 from a standstill to 100 km/h (62.14 mph) in just 5.5 seconds – the best performance value in this segment. The vehicle’s top speed is electronically limited to 250 km/h (155.34 mph). In the RS Q3, the Audi five-cylinder engine is working together with a standard Start-Stop-System for the first time. Other efficiency measures such as a regulated oil pump, which only pumps lubricant when needed, contribute to the car’s low average fuel consumption of 8.8 liters of fuel per 100 km (26.73 US mpg) which equates to 206 grams CO2 per km (331.52 g/mile).
A standard seven-speed S tronic transfers power to the drivetrain. It was designed in a compact three-shaft configuration, and its seventh gear has a long gear ratio to save on fuel. Drivers can choose between the D and S modes for automatic shifting of the dual clutch transmission, or they can shift manually – using the shift paddles on the steering wheel or the selector lever that sports a unique RS design. The Launch Control function controls acceleration from a standstill to attain optimal traction.
The heart of the quattro permanent all-wheel drive system is the hydraulically operated and electronically controlled multi-plate clutch located at the rear axle. It ensures proper distribution of torque between the front and rear axles.
The Audi RS Q3 impresses with dynamic and stable handling without sacrificing comfort. The RS sports suspension lowers the body of the compact high-performance SUV by 25 mm (0.98 in). The battery is located in the luggage compartment to achieve better weight distribution. The independent rear wheel suspensions are controlled by four links.
The electro-mechanical rack and pinion steering system operates very efficiently, conveying a stiff, precise steering feeling. An electro-mechanical parking brake and hill hold assist are also standard.
In the RS Q3, the internally ventilated and perforated brake discs at the front wheels have a wave design with wave-shaped outer contours, which saves approx. one kilogram (2.20 lb) of weight at the front wheels. The discs have a diameter of 365 mm (14.37 in), and they are gripped by eight-piston calipers painted black with RS logos. The electronic stabilization control (ESC) has a sport mode, and it can also be deactivated entirely.
The Audi RS Q3 comes on the German market with standard 19-inch alloy wheels. Three versions of 20-inch wheels are offered as well. One of these is the exclusive 5 dual-spoke V design, which is based on the Audi RS Q3 concept car that was shown at the 2012 Auto China motor show.
In addition to its engine, the Audi RS Q3 also demonstrates its special status within the Q3 line-up with a number of visual highlights. RS-specific design details emphasize the confident look of the compact, high-performance SUV. They consist of body accents and roof rails in matt aluminum, special door sill plates and door trim strips, a high-gloss black honeycomb front grille, RS front bumper and quattro emblem in the front air intake. A large roof spoiler, rear bumper with distinctive diffuser insert, large elliptical tailpipe and an RS Q3 logo accentuate the rear. At a length of 4,410 mm (14.47 ft), the dynamic top model is 25 mm (0.98 in) longer than the Audi Q3. It weighs in at 1,730 kg (3814.00 lb).
The Audi RS Q3 can also be customized by one of two optional styling packages – matt aluminum or black. Styling features include the flaps in the side air intakes, the trim on the diffuser and the fins on the roof spoiler. The Audi RS Q3 is available in eight exterior colors, including the exclusive Sepang Blue pearl effect.
The sporty lines of the exterior are continued in the interior styling. The instrument cluster has gray gauges with white scales and red pointers. Contrasting stitching in rock gray trim the three-spoke multifunction steering wheel with its flat bottom as well as the gear selector lever. The MMI and driver information system displays welcome the driver with the RS logo. Drivers can call up the boost pressure, oil temperature and a lap timer via the RS menu in the driver information system.
Along with the pedals, a foot support also shines in aluminum look, and the standard inlays are in piano finish black. quattro GmbH offers aluminum race or carbon as alternatives here. Black headlining is standard, and lunar silver headlining is optional.
Sport seats with embossed RS Q3 logos are also standard and are upholstered in black Alcantara/leather. Customers can also choose the optional Fine Nappa leather in black or lunar silver with contrasting stitching in rock gray or the design package with diamond stitching.
The cargo area has a base capacity of 356 liters (12.57 cubic ft), which can be increased to 1,261 liters (44.53 cubic ft) by folding down the split rear seat backs. A practical reversible loadliner is standard. Those wishing to transport even more cargo can order the towing bracket that is offered for the RS Q3.
Other standard features of the Audi RS Q3 include – in addition to the RS-specific driver information system – park assist plus, Audi sound system with ten loudspeakers, xenon plus headlights and LED tail lights. When they are not lit, the tail lights display a dark red tint.
In the infotainment area, a modular component system offers a wide range of options; at the top there is the hard-drive based navigation system, MMI Navigation plus. The surround sound system from Bose drives 14 loudspeakers with up to 465 watts of output power, while the Bluetooth car phone online together with WLAN hotspot connects the compact high-performance SUV with the Internet and brings the online services of Audi connect into the vehicle. Highly advanced driver assistance systems round out the options program.
In Germany, the base price is 54,600 euros, and deliveries begin in fall 2013.
The Audi RS 4 Avant
· V8 powerplant with 450 hp, 430 Nm (317.15 lb-ft)
· High-performance brakes with wave discs
· Unique combination of dynamics and everyday practicality
Neckarsulm – A modern classic from Audi is making a comeback: The third-generation RS 4 Avant combines potent performance with a high level of everyday practicality. It’s 4.2-liter V8 produces 331 kW (450 hp); the seven-speed S tronic and quattro permanent all-wheel drive transfer that power to the road.
The Audi RS 4 Avant uses the same high-revving, normally aspirated V8 engine that powers the RS 5 Coupe. The 4,163 cc powerplant produces 331 kW (450 hp) at 8,250 rpm for a specific output of 108.1 hp per liter. Its maximum torque of 430 Nm (317.15 lb-ft) is available from 4,000 to 6,000 rpm. The responsive V8 with its red-painted cylinder head covers accelerates the RS 4 Avant from zero to 100 km/h (62.14 mph) in 4.7 seconds on its way to a governed top speed of 250 km/h (155.34 mph). This can be increased to 280 km/h (173.98 mph) upon request.
Hand-built at Audi’s plant in Györ, Hungary, the 4.2 FSI engine combines its impressive power with exemplary efficiency, consuming on average less than 11 liters of fuel per 100 km (21.38 U.S. mpg).
With its high efficiency and long top gear, the standard seven-speed S tronic also contributes to the vehicle’s good fuel economy. Drivers can let the lightning-fast dual-clutch transmission shift automatically or change gears manually using the selector lever or the paddles on the steering wheel. For explosive starts, drivers can also activate Launch Control, which manages the engagement of the clutch at an optimum starting speed and minimum wheel slip.
Top traction: quattro drive with crown-gear center differential
Like every RS model from Audi, the RS 4 Avant comes standard with quattro permanent all-wheel drive. The heart of this system is the crown-gear center differential. This compact and lightweight component can vary the distribution of power between the front and rear axles immediately, smoothly and over a wide range, with up to 70 percent flowing to the front or as much as 85 percent to the rear. The default 40:60 ratio of the rear-biased configuration ensures sporty handling.
The self-locking crown-gear center differential works together with the torque vectoring system, which acts on all four wheels. If the load on the inside wheel is reduced too much while the car is being driven dynamically, the torque vectoring system brakes it slightly before unintended slip can occur. Audi offers the sport differential, which uses two superposition stages to actively distribute the power between the rear wheels, as an option.
Aluminum in abundance: the chassis
The chassis of the Audi RS 4 Avant is a very complex design. Many components of the five-link front suspension and the self-tracking trapezoidal-link rear suspension are made of aluminum. The new speed-dependent power steering is a highly efficient electromechanical system with a direct steering ratio for highly precise road feel. It helps the driver stay on course by making slight steering corrections when braking on surfaces with different amounts of grip.
The taut RS setup lowers the body by 20 millimeters (0.79 in) compared with the Audi A4 Avant. New, polished 19-inch, ten-spoke forged aluminum wheels shod with 265/35-series tires are standard. Audi also offers 20-inch wheels with 265/30-series tires. These are available in a new, polished, titanium-look, five-V-spoke design plus two additional variants in the five-arm rotor design.
Mounted behind the large wheels are internally vented wave disc brakes measuring 365 millimeters (14.37 in) in diameter up front. The steel friction rings with their wave-like outer contour are perforated and connected to the aluminum brake caps via pins. This concept reduces tensions, quickly dissipates heat and prevents transmission of temperature peaks. The new shape of the friction rings shaves a total of roughly three kilograms (6.61 lb) off the unsprung weight.
The calipers are painted high-gloss black; the front calipers have eight pistons each and sport RS logos. The ESP stabilization system has a Sport mode and can be fully deactivated. For the front axle, Audi offers the option of 380 millimeter (14.96 in) carbon fiber ceramic discs and six-piston calipers in anthracite gray. The ceramic brakes are especially lightweight, robust and durable.
The Audi drive select driving dynamics system is among the standard equipment for the RS 4 Avant. With it, the driver can switch between three modes – comfort, auto and dynamic – to determine the characteristics of the steering, the seven-speed S tronic and the throttle valve. Audi drive select can even vary the sound of the exhaust system, double-declutching when downshifting in dynamic mode. If the car is equipped with an Audi navigation system, a largely driver-configurable custom mode is also available.
In addition to the sport differential, another component available for Audi drive select is dynamic steering. It varies its steering ratio by nearly 100 percent depending on the speed driven and automatically countersteers slightly at the cornering limit for even more precise and stable handling.
Another particularly dynamic damping technology available as an option from Audi is the sport suspension plus with dynamic ride control (DRC). Oil lines and a central valve connect diagonally opposed pairs of shock absorbers. During fast cornering, the system boosts the stabilization of the front outside wheel, for example.
The damping characteristic of the sport suspension plus is variable, with a choice of three settings available via Audi drive select.
Athletic: the exterior design
The exterior design flaunts the athletic character of the RS 4 Avant. The hexagonal single-frame grille is set in a frame with a matte aluminum-look finish; its honeycomb insert is finished in high-gloss anthracite. LED daytime running lights encircle the xenon plus units like a clasp in the wedge-shaped headlights. The air flows through large openings divided by crossbars and embedded in a distinctive bumper featuring a splitter edge like on a race car.
When viewed from the side, the chiseled side sill caps and flared wheel wells catch the eye. The flared rear side elements with sharp horizontal upper edges are a nod to that all-wheel drive pioneer from 1980, the Audi quattro. The side mirror housings and trim strips have a matte aluminum-look finish, and a discrete roof spoiler at the back ensures the necessary downforce.
The distinctive bumpers and the two oval tailpipe caps of the dual exhaust system dominate the rear end and are integrated into an upturned diffuser. Audi also offers a sport exhaust system with a voluminous sound and black caps. Elegant light strips adorn the LED rear lights.
The Audi RS 4 Avant is 20 millimeters (0.79 in) longer and 24 millimeters (0.94 in) wider than the A4 Avant, but 20 millimeters (0.79 in) lower. A choice of eight colors is available: one solid and one metallic finish, four pearl-effect colors and the two specially pigmented crystal-effect colors, Prism Silver and Panther Black. The extensively clad underbody integrates air vents for the seven-speed S tronic and the front brakes.
Sporty black: the interior
The interior of the RS 4 Avant is clad completely in black, with the exception of the roofliner, which is optionally available in Moon Silver. Chrome clasps subtly accentuate switches and control elements. Carbon inlays are standard, with brushed matte aluminum, Aluminum Race, black piano finish or a light stainless steel mesh available as options.
The standard heated front sport seats with integrated headrests are power adjustable and covered in a combination of black leather and Alcantara. Fine Nappa leather in either Black or Moon Silver accentuated with Stone Gray piping is optionally available. Other options include bucket seats or luxurious, climate-controlled deluxe seats with a ventilation function. The thick ring of the leather multifunction sport steering wheel is flattened at the bottom, and the shift paddles mounted on the back of it sport an aluminum-look finish.
The driver information system with color display includes an RS menu with a lap timer and an oil thermometer. Both it and the MMI monitor display a special RS welcome screen when the car is started.
The instrument cluster bezel shines with a piano finish, and the design of the selector knob of the seven-speed S tronic is unique to the RS. Typical of all RS vehicles, the door openers are two delicate bars. The pedals, the footrest, the air vents, the shift paddles on the steering wheel, the MMI buttons and other controls shine in an aluminum-look finish. Aluminum inserts adorn the door sill trims, which are accentuated with RS 4 badges.
Audi offers exclusive high-grade leather packages for all seating options, including a design package with honeycomb quilting for the RS 4 bucket seats. Rounding out the list of optional equipment is a broad range of state-of-the-art driver assistance and communication systems, including the Bluetooth online car phone that connects the RS 4 Avant with the Internet.
Options for the luggage compartment, which offers up to 1,430 liters (50.50 cu ft) of cargo space, include a rail system with load securing set and a power hatch.
Delivery of the Audi RS 4 Avant started in September 2012 at a base price of €76,600 in Germany.
The Audi RS 5 Coupé
The RS 5 Coupé is the star athlete of the A5 family. It offers the power and handling of a powerful sports car packaged in the body of an alluringly elegant coupe. The design has now gained several new, sharp accents, with numerous features that characterize the other A5 models also making their way to the RS 5.
The Audi RS 5 Coupé uses a high-revving, normally aspirated V8 displacing 4,163 cc. This engine is closely related to the V10 that powers the R8 high-performance sports car. The 4.2 FSI delivers 331 kW (450 hp) at 8,250 rpm, with the peak torque of 430 Nm (317.15 lb-ft) available between 4,000 and 6,000 rpm. The engine has a specific output of 108.1 hp per liter of displacement. The potent response, the eager revving and the rich, melodious sound mark the V8 as a thoroughbred racing engine.
Hand-built at the plant in Györ, Hungary, the 4.2 FSI launches the Coupé from 0 to 100 km/h (62.14 mph) in 4.5 seconds. Audi will increase the electronically governed top speed from 250 to 280 km/h (155.34 to 173.98 mph) upon request. Thanks to the combination of technologies from the Audi modular efficiency platform, which also includes a recuperation system, the high-tech V8 consumes significantly less fuel on average than its direct competitors.
With its high efficiency and its long top gear, the standard seven-speed S tronic also contributes to the good fuel economy. Drivers can let the lightning-fast dual-clutch transmission shift automatically or change gears themselves using the selector lever or with paddles on the steering wheel. The integrated launch control program provides for rocket-like starts by managing the engagement of the clutch at mid-level revs.
High end: quattro with crown-gear differential
Like all RS models, the RS 5 Coupé also applies its power to the road with quattro permanent all-wheel drive. The crown-gear center differential at its heart is compact and lightweight. It can vary the distribution of torque between the front and rear axles lightning-fast and over a wide range, with up to 70 percent flowing to the front or as much as 85 percent to the rear, as necessary. The default 40:60 ratio of the rear-biased configuration ensures sporty handling.
The crown-gear center differential works together with the torque vectoring system, which acts on all four wheels. If the load on the inside wheel is reduced too much while the car is being driven dynamically, that wheel is braked slightly before it can begin to slip. Audi offers the sport differential as a complementary option that actively distributes the power between the rear wheels via two superposition stages.
Precise and stable: the chassis
The chassis of the RS 5 Coupé unites fast and precise turn-in, high cornering speeds and supreme stability. Most of the components of the five-link front suspension and the self-tracking trapezoidal-link rear suspension are made of aluminum. The new speed-dependent power steering is an electromechanical system with a direct steering ratio for highly precise road feel. It supports the driver with slight steering corrections when braking on surfaces with different amounts of grip. Because the power steering draws no energy when driving straight ahead, it helps to enhance efficiency.
The taut setup lowers the body by 20 millimeters (0.79 in) compared with the Audi A5. Newly designed, 19-inch forged aluminum wheels with 265/35-series tires are standard; 20-inch wheels with 275/30-series tires are available as an option for the high-performance coupe.
The brake system of the RS Coupé features large, internally ventilated wave brake discs, with the front discs measuring 365 millimeters (14.37 in) in diameter. The steel friction rings with their wave-like outer contour are perforated and connected to the aluminum brake caps via pins. This direct structure reduces tensions, quickly dissipates the heat and prevents the transmission of temperature peaks. Moreover, the redesigned shape of the friction rings results in three kilograms (6.61 lb) of weight being saved in total, thus improving the balance of unsprung masses.
The calipers are painted high-gloss black; the front calipers have eight pistons each. The RS 5 can be optionally equipped with carbon fiber-ceramic discs up front. The electronic stabilization program (ESP) integrates a sport mode and can be switched off entirely.
Upon request, Audi equips the RS 5 with a particularly dynamic damping technology – the sport suspension plus with DRC dynamic ride control. The diagonally opposed pairs of shock absorbers are linked by hydraulic lines and a central valve. During fast cornering, the system intensifies the stabilization of the front outside wheel. The sport suspension plus features a three-stage, variable damping characteristic.
The Audi drive select driving dynamics system comes standard with the RS 5 Coupé. This system allows the driver to select between three modes – comfort, auto and dynamic – for the characteristics of the steering, the seven-speed S tronic and the accelerator. And if the car is equipped with an Audi MMI navigation system, there is also a fourth mode – individual – which can be configured by the driver. Audi drive select can also modulate the sound of the exhaust system, double-clutching when downshifting in dynamic mode.
Dynamic steering is another module available for Audi drive select beside the sport differential and the damping characteristic in the sport suspension plus. It uses a superposition gear to vary the steering ratio by nearly 100 percent as a function of speed and countersteers slightly at the cornering limit.
Unmistakable: The design
The RS 5 Coupé has an athletic road stance, and its classically elegant two-door lines dazzle with clear-cut accents. The new single-frame grille with beveled upper corners features a high-gloss, anthracite gray honeycomb structure and a matt aluminum-look frame. The standard xenon plus headlights are framed by narrow strips of LED daytime running lights. The air flows through large openings embedded in a distinctive bumper featuring a splitter edge like on a racing car. Sharper edges make the engine hood appear more three-dimensional so that the RS 5 looks even lower and wider when viewed from the front.
The flared aluminum front fenders and the rear side elements with the sharp horizontal upper edges are reminiscent of two classic Audi models from the 1980s – the all-wheel drive pioneer Audi quattro and the Sport quattro. The side sills sport chiseled caps; the trim strips and the side mirror housings have a matt aluminum-look finish.
The tail end is dominated by the two oval exhaust pipes of the dual exhaust system, which are integrated into the redesigned bumper. Audi also offers a sport exhaust system with a more voluminous sound and black exhaust tip bezels. The LED rear lights are also new and feature continuous light strips. The large diffuser extends far upward, and the spoiler in the rear hatch extends automatically at 120 km/h (74.56 mph).
The extensively clad underbody integrates air vents for the seven-speed S tronic and the front brakes. Thanks to its advanced aerodynamics, the RS 5 Coupé generates downforce at high speed to further enhance stability.
The dynamic looks alter the dimensions slightly. The RS 5 Coupé is 23 millimeters (0.91 in) longer and six millimeters (0.24 in) wider than the A5 Coupé, but six millimeters (0.24 in) lower. Eight exterior colors are available, from solid, metallic and pearl effect finishes to a specially pigmented crystal effect paint.
Dynamic elegance: The interior
The vehicle’s dynamically elegant styling also extends to the interior. The standard sport seats with integrated headrests are power adjustable and covered in a combination of black leather and Alcantara. Audi also offers seat upholstery in Fine Nappa leather in a choice of black or lunar silver, both subtly accented with rock gray piping. Other options include bucket seats with folding backrests or comfortable, climate-controlled comfort seats with a ventilation function. The interior is bathed in black, with narrow chrome clasps at the switches and control elements providing delicate accents. Inlays are available in a choice of carbon, brushed or etched aluminum, a high-gloss piano finish or a light-colored stainless steel mesh.
The new leather multifunction sport steering wheel with its thick rim is flattened at the bottom and features a new, even easier control concept. The ignition key and the shift lever knob have also been redesigned. Even the steering column stalks have been updated. The instruments have black gauges and white lettering with special scaling. When the ignition is turned, the red needles of the speedometer and tachometer run quickly up to the limit before returning to zero for a touch of sporty flair. Typical of all RS vehicles, the door openers are two delicate bars.
The driver information system with color display includes an RS menu with a lap timer and an oil thermometer. It displays a special RS welcome screen when the car is started. A piano-finish fascia in the instrument panel frames the instrument cluster. The pedals, the footrest and the buttons of the optional MMI navigation systems shine in an aluminum-look finish. Aluminum inserts adorn the door sill trims, which are accentuated with RS 5 badges.
Audi also offers numerous exclusive features for the interior. A carbon design package is available for the engine compartment, as are a variety of styling packages for the body in black or matt aluminum look. A broad range of high-performance assistance and communication systems round out the optional extras program. Among these are adaptive cruise control, Audi side assist, adaptive light, MMI navigation plus, the Bluetooth online car phone and the Bang & Olufsen sound system.
The new 4.0 TFSI
Audi is expanding its engine lineup with a new, high-performance gasoline engine. The 4.0 TFSI, which is used in slightly different configurations in the S6, S6 Avant, S7 Sportback and S8, develops between 309 kW (420 hp) and 382 kW (520 hp), and as much as 650 Nm (479.42 lb-ft) of torque. The new V8 is a high-tech engine featuring numerous innovative solutions.
The youngest member of the large Audi family of V engines, the 4.0 TFSI shares all of their typical characteristics. It has the classic cylinder angle of 90 degrees, the chain drive for the four camshafts and ancillary units is on the back to save space, and the cylinder case is a cast aluminum-silicon alloy. This eight-cylinder unit is very light in weight, and its highly compact construction has resulted in its length being reduced to 497 mm (19.57 in).
Fuel is provided via Audi’s FSI direct injection system. Switchable flaps in the intake ports induce a rolling type of movement in the incoming air for improved combustion. Like almost every Audi engine, the new 4.0 TFSI also follows the principle of downsizing, where forced induction replaces displacement. One turbocharger per cylinder bank compresses the intake air.
This is known as twinscroll technology, where the exhaust flows to the turbine wheel at high speed through two separate ports and enables torque to be developed extremely early, just above idle.
The two turbochargers and the intercooler are located in the inside V of the cylinder banks rather than in the usual location outside next to the crankcase. Audi has structured the cylinder heads in an innovative way. The exhaust side is on the inside, the intake side on the outside. This layout provides for compact dimensions and short gas paths with minimal flow losses, and the 4.0 TFSI reacts immediately to the gas pedal as a result. Sophisticated insulation of the hot components, in particular the exhaust manifold, stabilizes the thermal conditions in the inside V.
A further innovation is Audi’s cylinder management. In low to intermediate load and rev ranges, it deactivates two cylinders in each bank of the V8, reducing fuel consumption significantly. Thanks to a comprehensive package of innovative measures, the engine remains smooth and quiet during these phases. Shutting down the cylinders is virtually imperceptible. This cylinder management function is provided by the latest version of the Audi valvelift system by closing the intake and exhaust valves of the affected cylinders.
The 4.0 TFSI employs all the technologies from Audi’s modular efficiency platform. These range from measures to reduce friction, the start-stop system and the recuperation system to innovative thermal management that deactivates the water pump during the warmup phase to quickly bring the oil up to temperature. The new regulated oil pump varies the oil pressure in two stages, and the oil jet cooling for the piston heads is characteristic-controlled. The new 4.0 TFSI provides for powerful performance in all of the large S models while at the same time demonstrating its high efficiency potential.
Delivery of the Audi RS 5 Coupé started in April 2012 at a base price of €78,750 in Germany.
Dynamic performance where the sky’s the limit – The Audi RS 5 Cabriolet
· Audi extends its model series with a high-end convertible
· 4.2 FSI engine with 331 kW (450 hp), 0 to 100 km/h (62.14 mph) in 4.9 seconds
· Elegant and spacious body with lightweight cloth soft top
Dynamic performance where the sky’s the limit – Audi introduces the RS 5 Cabriolet. The four-seat convertible with a cloth soft top entices with a unique combination of elegance and power. Its 4.2 FSI, a high-revving naturally aspirated V8 engine, outputs 331 kW (450 hp). It accelerates the high-performance sports car from 0 to 100 km/h (62.14 mph) in 4.9 seconds.
In the RS 5 Cabriolet, Audi dynamics takes on an especially beautiful form in the car’s flowing side profile with perfectly balanced proportions and sharp details.
A frame in matt aluminum look surrounds the hexagonal single-frame grille; its honeycomb grille insert that sports an RS 5 logo shines in anthracite. Wedge-shaped headlights with wave-like lower edges illuminate with xenon plus lamps and LED strips that form the daytime running lights. Large air intakes are embedded in the distinctively shaped front apron whose ends run out into splitter edges.
Sill add-ons and wheel housing extensions dominate the car’s appearance in side profile; the tornado line that defines the shoulder of the RS 5 Cabriolet was drawn to look especially sharp. The door mirror housings have an aluminum look, while the surface of the windshield frame and the decorative trim strips of the window channels and the soft top box cover are made of matt anodized aluminum.
The lightweight textile roof of the RS 5 Cabriolet spans over the generously proportioned interior space like a low curved dome; a special foam layer in the roof delivers high acoustic comfort. At the press of a button, the soft top opens and closes fully automatically in 15 seconds and 17 seconds respectively – even when driving at speeds of up to 50 km/h (31.07 mph).
When open, it hardly affects the size of the spacious luggage compartment – it only requires 60 liters (2.12 cu ft) of its 380 liters (13.42 cu ft) total volume. The split rear seatbacks can be folded over individually, and a load-through hatch from the trunk to the rear seating area improves variability. Special reinforcements contribute to the convertible body’s high rigidity, and aluminum front fenders compensate for some of the added weight of the reinforcements.
Elegant LED light strips illuminate in the taillights, which operate without any conventional incandescent lamps. Like the lights, the rear bumper was also redesigned; its diffuser is now much higher, and a honeycomb screen insert encloses the two large elliptical tailpipes of the exhaust system. On the trunk lid there is a subtle matt carbon spoiler lip for more downforce; it may be painted in the exterior color as an option.
The Audi RS 5 Cabriolet measures 4,649 mm (15.25 ft) long, 1,860 mm (6.10 ft) wide and 1,380 mm (4.53 ft) high, and its wheelbase is 2,751 mm (9.03 ft). Eight exterior colors are available – a monochrome color, four metallic and pearl effect colors and three crystal effect paints. The soft top is available in black, gray, red or brown. As options, Audi can install a styling package in matt aluminum as well as an engine compartment design package that uses carbon fiber-reinforced polymer (CFRP) materials. The car’s drag coefficient is 0.34; underbody panels make a significant contribution towards aerodynamic refinement.
A typical RS 5 highlight is its three-spoke steering wheel with flat-bottomed rim that is trimmed in perforated leather. The multifunction keys are intuitive, as are all other controls in the RS 5 Cabriolet. The terminal of the optional MMI navigation plus system, for example, only requires six permanent keys for the main menus, and just a single button control suffices for Audi drive select. White numerals on black dials provide a strong contrast and are easy to read. Sport-oriented drivers will find a lap timer for lap times and an oil temperature gauge in the driver information system.
The sport seats have power adjustments, high side panels for optimal lateral support, integrated head restraints, a lumbar support and a pull-out thigh support. They are upholstered in a combination of leather and Alcantara or in the optional black or lunar silver Fine Nappa leather. All leather types are pigmented to inhibit heating by sunlight. Seat alternatives are manually adjustable bucket seats or climate-controlled comfort seats with a ventilation feature.
The interior of the Audi RS 5 Cabriolet is styled in black, and the inner soft top liner can be ordered in the optional color star silver. Fine chrome highlights, understated high-gloss black trim and carbon inlays underscore the car’s dynamic appearance. Upon request, Audi can deliver the inlays in Aluminum Race, piano finish black, matt brushed aluminum or stainless steel mesh at no additional cost.
There are RS logos on the backs of the seats, the aluminum inlays in the door sill plates, the steering wheel, the tachometer and the gear selector grip of the seven-speed S tronic. The inside door handles consist of two slender ribs, and the pedals and many other controls glisten in aluminum look. The Audi exclusive program offers many other customizing options.
Propulsive power for the RS 5 Cabriolet is supplied by a high-revving, naturally aspirated V8 engine with FSI direct injection. From its 4,163 cc of engine displacement, it outputs 331 kW (450 hp) at 8,250 rpm and produces a maximum torque of 430 Nm (317.15 lb-ft) between 4,000 and 6,000 rpm. The 4.2 FSI with red painted cylinder head covers that is manually assembled in the Hungarian plant in Győr achieves a specific power output of 79.5 kW (108.1 hp) per liter engine displacement; each hp only needs to move 4.267 kg (9.41 lb) of vehicle weight. The long-stroke engine with its aluminum crankcase breathes freely; flaps in the exhaust tailpipes vary the sonorous acoustic backdrop. As an option, Audi can deliver a sport exhaust system with black tailpipe trim.
The Audi RS 5 Cabriolet rockets from a standstill to 100 km/h (62.14 mph) in 4.9 seconds. The car’s top speed is limited to 250 km/h (155.34 mph); at customer request, Audi can boost this to 280 km/h (173.98 mph). The powerful V8 has a combined fuel consumption of 10.7 l/100 km (21.98 US mpg). Its cylinder liners and chain drive are optimized for minimal friction, and the oil pump is only driven as needed.
Dual-clutch transmissions like the seven-speed S tronic of the RS 5 Cabriolet are distinguished by a high level of efficiency, which is further improved in this model by the long ratio of the highest gear. Shifts are performed so quickly and smoothly by alternating the clutches that they are hardly perceptible. The driver can have the seven-speed S tronic shift automatically in the D or S program, or he/she can manually shift with the gearshift lever or the paddles on the steering wheel. The Launch Control function is a useful drive-off assistant for the race course. It enables an optimal start by letting out the clutch at an ideal drive-off engine speed.
The quattro permanent all-wheel drive system gives the RS 5 Cabriolet a decisive advantage in traction and stability. Its technological centerpiece, the crown-gear center differential, is lightweight and compact. In normal driving operation, it distributes torque between the front and rear axles at a 40:60 ratio; if necessary, it can direct up to 70 percent to the front or a maximum of 85 percent to the rear. Torque vectoring – an intelligent software solution – completes the center differential’s work tasks.
If a wheel at the inside of a curve begins to lose its grip when cornering at speed, it is braked slightly before any slip occurs – this keeps the RS 5 Cabriolet neutral for an exceptionally long time in extreme driving conditions.
As an option, Audi can install a sport differential that actively distributes power between the rear wheels via two superposition gears. A perfect supplement to the quattro drivetrain, it presses the RS 5 Cabriolet into the curve at the handling limits, counteracting any tendency to oversteer or understeer right from the outset.
The chassis of the four-seat convertible exhibits a high level of technical complexity. Many components of the five-link front suspension and the self-tracking trapezoidal-link rear suspension are made of aluminum. The speed-dependent power steering system utilizes an electromechanical drive unit; it provides direct and sensitive steering feedback and is highly efficient. The body is 20 mm (0.79 in) lower than that of the Audi A5 Cabriolet; its mounts are stiffer, and its anti-roll bars are larger and stronger.
The standard wheels are forged aluminum wheels in machine-polished ten-spoke design, size 9 J x 19 with 265/35 tires; 20-inch wheels in three attractive designs with tires in 275/30 format are available as options.
The brake system employs internally ventilated and perforated discs in a weight-saving wave design; the front discs are 365 mm (14.37 in) in diameter. The wave-shaped outer contour of the friction rings reduces unsprung mass by a total of about three kilograms (6.61 lb). Pins are used to join the discs to the aluminum brake pots – a concept adopted from motorsport. The brake calipers are painted black; the front brakes operate with eight pistons each. The ESC stabilization system has a Sport mode and can also be completely deactivated. Audi can deliver the car with carbon fiber-reinforced ceramic front discs and six-piston calipers as an option.
Audi drive select is a standard feature in the RS 5 Cabriolet. The driver can use this function to vary the characteristics of the steering system, seven-speed S tronic, throttle valves and exhaust system sound flaps to one of the modes comfort, auto or dynamic; if an MMI navigation system is installed, the ‘individual’ mode is also offered. The sport differential, adaptive cruise control and dynamic steering – whose gear ratio can be varied by nearly 100 percent as a function of vehicle speed – can also be incorporated into the system.
Another option that is controlled by Audi drive select is sport suspension plus with Dynamic Ride Control (DRC) – a purely mechanical system that operates without any delays. Each pair of diagonally opposing shock absorbers is interconnected via hydraulic oil lines and a central valve; when cornering at speed, the system increases support of the spring-deflected front wheel at the outside of the curve. The shock absorber characteristic can be adjusted over three levels.
The Audi RS 5 Cabriolet is delivered with an extensive set of standard features. They include the parking system plus, driver and front passenger seat heating, automatic belt feeder, wind deflector, lighting package, driver information system with rest recommendation and a comprehensive package of restraint systems. In case of an impending roll-over accident, strong aluminum plates deploy upwards behind the rear head restraints.
Sporty and luxurious options include three-stage head-level heating, convenience key, high-beam assistant, adaptive light and three-zone deluxe automatic air conditioning.
All assistance systems offered in the A5 model lineup are available as options in the RS 5 Cabriolet as well. Adaptive cruise control maintains the four-seat convertible at the desired distance to a vehicle driving ahead in traffic and supports the driver in braking. At speeds below 30 km/h (18.64 mph), it initiates a full brake application in an emergency situation. Audi side assist monitors the space behind the vehicle, which helps to ensure safe lane changes. Audi active lane assist makes it easier to stay in a driving lane. The parking system plus can be extended to include a reversing camera.
In the multimedia field, Audi is offering a comprehensive modular component system; at the very top there is MMI navigation plus which includes a large hard drive, DVD drive and seven-inch color monitor. An ideal complement is Audi connect with car phone, which connects the RS 5 Cabriolet to the Internet. Audi connect lets passengers freely surf the web with their mobile end devices via an integrated WLAN hotspot. Customized online services from Audi connect are also available to the driver – they range from Audi traffic information online to navigation with Google Earth images and Street View.
Customer deliveries of the Audi RS 5 Cabriolet begin in April 2013 in Germany. The base price in the home market will be 88,500 euros.
Groundbreaking performance: The new Audi RS 6 Avant
· Powerful twin-turbo V8: 4.0 TFSI with 412 kW (560 hp) and 700 Nm (516.29 lb-ft)
· Reduced weight for greater efficiency and stronger performance
· 0 – 100 km/h (62.14 mph) in 3.9 seconds, top speed 305 km/h (189.52 mph)
Neckarsulm – The new Audi RS 6 Avant stands for groundbreaking performance. It is lighter and more efficient than the previous model, and performance has been improved once again. The sprint from 0 to 100 km/h (62.14 mph) takes just 3.9 seconds, and top speed is 305 km/h (189.52 mph). The 4.0 TFSI develops 412 kW (560 hp), but is content with an average fuel consumption of just 9.8 liters per 100 kilometers (24.00 US mpg).
The new Audi RS6 Avant is a high-performance sports car for everyday use. Its character and uncompromisingly sporty tuning is the work of quattro GmbH, a wholly-owned subsidiary of AUDI AG. The company’s RS models with their powerful engines form the dynamic spearhead of the model program. The abbreviation “RS” stands for the most powerful version of a model series, for quattro permanent all-wheel drive, for extreme handling, for an understated appearance and for full everyday utility.
The 4.0 TFSI, which debuted last year, is a perfect example of Audi’s downsizing strategy in the high-performance category. In the new Audi RS 6 Avant, the twin-turbo V8 delivers confidence-inspiring power in every driving situation from its displacement of 3,993 cc. Peak output of 412 kW (560 hp) is reached between 5,700 and 6,600 rpm, with a constant 700 Nm (516.29 lb-ft) of torque available between 1,750 and 5,500 rpm.
Pulling power develops quickly due in large part to the two large twin-scroll turbochargers. They are mounted together with the intercooler in the inside V of the cylinder banks. The exhaust side of the cylinder heads is also on the inside, the intake side outside. This concept allows for a compact design and short gas paths with minimal flow losses.
The RS-specific engine management and unthrottled intake system also contribute to the eight-cylinder engine’s spontaneous response. The 4.0 TFSI delivers a sporty, full-throated sound. Switchable flaps in the exhaust system make the sound even fuller, if desired. Audi also offers an optional sport exhaust system.
The powerful twin-turbo V8 accelerates the new Audi RS 6 Avant from zero to 100 km/h (62.14 mph) in a best-in-segment 3.9 seconds. In the standard configuration, top speed is electronically limited to 250 km/h (155.34 mph). This is increased to 280 km/h (173.98 mph) with the optional Dynamic package. With the Dynamic plus package, Audi reigns in the engine only upon reaching 305 km/h (189.52 mph). According to the European driving cycle, the high-performance Avant consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg). Among the factors contributing to this figure are the new, standard start-stop system and innovative thermal management. Fuel consumption has been reduced by roughly 30 percent compared to the previous model.
One pioneering efficiency technology in the new Audi RS 6 Avant is the cylinder on demand (COD) system. At low to intermediate loads and engine speeds, it shuts down the intake and exhaust valves of cylinders 2, 3, 5 and 8. The 4.0 TFSI then runs as a four-cylinder engine until the driver accelerates more strongly again. Efficiency in the active cylinders is increased because the operating points are displaced toward higher loads.
The changeover from four and eight-cylinder operation takes just a few hundredths of a second. About the only thing noticeable to the driver is an indication in the instrument cluster. The COD technology reduces ECE fuel consumption by roughly five percent. Even greater savings of approximately 10 percent are possible when driving at moderate speeds. Active engine bearings use out-of-phase counter-oscillations to compensate for the vibrations that occur during four-cylinder operation.
The 4.0 TFSI is paired with an eight-speed tiptronic featuring shortened shift times. The automatic transmission offers D and S modes. Drivers who wish to shift for themselves can use the shift paddles on the steering wheel or the selector lever, which sports a unique RS design. The lower gears of the tiptronic are tightly spaced for sporty performance, while a tall eighth gear reduces fuel consumption.
At the heart of the quattro permanent all-wheel drive system with torque vectoring is a self-locking center differential with an elevated locking value. An oil cooler regulates its temperature. If desired, the sport differential distributes the power steplessly between the rear wheels to further increase agility and stability.
The new RS 6 Avant is the first RS model from Audi to come standard with a specifically tuned air suspension. The dynamic setup of the RS 6 adaptive air suspension lowers the body by 20 millimeters (0.79 in). The system combines the air suspension with controlled damping and takes into account the road conditions, the driving style and the mode chosen in the driving dynamics system Audi drive select, with which the driver can influence the function of key components in multiple steps.
Audi also offers the tauter sport suspension plus with Dynamic Ride Control (DRC) as an alternative to the RS 6 adaptive air suspension. This system uses steel springs and three-way adjustable shock absorbers that are interconnected diagonally by means of oil lines and a central valve for improved body roll stability. Another option is dynamic steering, which features steplessly variable steering boost and ratios. This system can also be integrated into Audi drive select and, just like the standard electromechanical power steering, is tailored specifically for the RS 6 Avant.
The brakes offer uncompromising performance. The four internally vented discs feature a weight-saving wave design with a wave-like outer contour. The front discs measure 390 millimeters (15.35 in) in diameter and are gripped by black, six-piston calipers. Customers can also opt for red brake calipers. Also available as an option are carbon fiber-ceramic brake discs measuring 420 millimeters (16.54 in) in diameter. Their calipers are painted anthracite gray. The electronic stabilization control (ESC) has a Sport mode and can also be deactivated entirely.
The new Audi RS 6 Avant comes standard with high-gloss, 20-inch, forged wheels in a seven twin-spoke design. Optional 21-inch cast wheels are available in three versions: high-gloss silver, polished black and polished titanium-look.
The body plays a major role in the handling. It is roughly 20 percent aluminum and includes numerous components made of high-strength steel. The new Audi RS 6 Avant weighs roughly 100 kilograms (220.46 lb) lighter than its predecessor. The improved power-to-weight ratio contributes to even better handling with improved performance coupled with reduced fuel consumption.
Numerous RS-specific design details underscore the distinctive appearance of the high-performance Avant. Most noticeable are the matte aluminum applications on the body, the high-gloss black protective grille at the front of the car, the bumpers, the fender, sill flares and the large roof spoiler. At the rear of the car, the diffuser and the two large, elliptical exhaust tailpipes make a bold statement.
Two optional appearance packages – Matte Aluminum or Carbon – further customize the look and include such things as quattro badges on the central front air inlet. With the Carbon appearance package, the front splitter and the diffuser are even more boldly shaped. The new Audi RS 6 Avant is available in nine exterior colors, including the exclusive shade Daytona Gray matte. Additional options from the Audi exclusive range offer numerous opportunities for customization.
The sportily elegant cockpit of the new Audi RS 6 Avant is singularly tailored to the driver. The dial instruments feature black faces, white dials and red needles. The key; the flat-bottomed, three-spoke, multifunction steering wheel; the illuminated entry sills; the tachometer and the displays for the MMI as well as the driver information system (DIS) sport RS logos.
A new feature in the RS menu of the DIS is the shift light. Green segments are illuminated as revs increase. The bar turns red and begins to blink when revs approach the red line. Displays for the gear selected, boost pressure, oil temperature and a digital speedometer round out the RS 6-specific driver information system.
The footrest, pedals and switches in the MMI navigation plus terminal shine in an aluminum-look finish. The decorative bezel surrounding the retractable monitor sports a piano finish; the interior door openers feature a delicate double-bar design – a classic RS feature. Carbon inlays are standard; six additional materials are available as options. A black headlining is standard; Moon Silver or black Alcantara are optional.
RS sport seats with pronounced side bolsters, integrated head restraints and RS 6 logos are standard. They are covered in a combination of black Alcantara and leather, and the center sections feature diamond quilting. The seats can also be covered in high-grade, honeycomb-quilted Valcona leather in either black or Moon Silver. Audi offers optional power-adjustable deluxe seats with memory function.
The Audi RS 6 Avant comes standard with two sportily molded rear seats. A three-person bench seat is available as an option. The luggage compartment holds up to 1,680 liters (59.33 cu ft).
The new Audi RS 6 Avant comes with a generous list of standard equipment, including xenon plus headlights, LED rear lights, a tire-pressure control system, illuminated entry sills and the custom driver-information system. Also on board are the parking system plus, cruise control, three-zone automatic air conditioning, MMI navigation plus with MMI touch and the 10-speaker Audi sound system.
Options include LED headlights with a unique design, ceramic brakes front and rear, the sport differential on the rear axle and the sport suspension plus with Dynamic Ride Control (DRC). The Dynamic package, Dynamic package plus, Comfort package and practically every high-end option available in the model series are also available for the RS 6 Avant. These include the head-up display and the high-performance driver assistance systems as well as the Bang & Olufsen Advanced Sound System with 15 speakers and 1,200 watts of total power. The Bluetooth online car phone – the perfect complement to the MMI navigation plus – delivers web-based Audi connect services to the car.
Customer deliveries of the Audi RS 6 Avant begin in the second half of the year 2013 in Germany. The base price in the home market will be 107,900 euros.
Dynamics at their most beautiful – the Audi RS 7 Sportback
· Outstanding performance with high efficiency
· Twin-turbo V8: 4.0 TFSI with 412 kW (560 hp) and 700 Nm (516.29 lb-ft)
· Optional top speed of 305 km/h (189.52 mph)
Neckarsulm – Audi is expanding its RS model lineup: The RS 7 Sportback stands for dynamics at their most beautiful. The large five-door coupe uses a 4.0 TFSI engine producing 412 kW (560 hp). The sprint from zero to 100 km/h (62.14 mph) takes just 3.9 seconds, and the speed governor can be deactivated upon customer request to permit a top speed of up to 305 km/h (189.52 mph). Despite this superior performance, the Audi RS 7 Sportback consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg).
Aesthetic design, innovative technology and impressive sportiness: The RS 7 Sportback, the large five-door coupe from Audi, combines many strengths to produce a fascinating character. Its strong heart is the 4.0 TFSI, which takes Audi’s downsizing strategy to the high-end category. The twin-turbo V8 displaces 3,993 cc and develops awesome power, with 412 kW (560 hp) available between 5,700 and 6,600 rpm. A constant 700 Nm (516.29 lb-ft) of torque are available between 1,750 and 5,500 rpm.
Because the high-revving four-liter engine has been rigorously designed for low load-change and flow losses, it develops this power quickly and spontaneously. The cylinder heads have the exhaust side on the inside and the intake side on the outside. The two twin-scroll turbochargers, which produce up to 1.2 bars of relative boost pressure, are located together with the intercooler in the inside V of the cylinder banks. Consequently, the gas paths are very short and response very good. The RS-specific engine management and unthrottled intake system also contribute to the dynamic character of the twin-turbo V8. Switchable flaps in the exhaust system make the engine sound even fuller at the push of a button or under strong acceleration. Audi also offers an optional sport exhaust system.
The RS 7 Sportback sprints from 0 to 100 km/h (62.14 mph) in just 3.9 seconds. Audi limits the top speed in the standard configuration to 250 km/h (155.34 mph). Top speed with the optional dynamic package is 280 km/h (173.98 mph) and 305 km/h (189.52 mph) with the dynamic package plus.
Yet the new top model of the model series consumes on average just 9.8 liters of fuel per 100 km (24.00 US mpg). This top value is due in part to the standard start-stop system and innovative thermal management.
The most innovative efficiency technology in the new Audi RS 7 Sportback is the cylinder on demand (COD) system. At low to medium loads and engine speeds, it deactivates cylinders 2, 3, 5 and 8 by closing their valves via electromechanical actuators. The 4.0 TFSI then runs as a four-cylinder engine until the driver accelerates more strongly again. The operating points in the active cylinders are displaced toward higher loads, increasing efficiency.
All of these operations take just a few hundredths of a second and occur so smoothly and quickly that they can hardly be felt or heard. Active engine bearings, another high-end solution from Audi, use out-of-phase counter-oscillations to compensate for the slight vibrations that occur during four-cylinder operation. The COD technology reduces NEDC fuel consumption by roughly five percent, and even greater savings of approximately 10 percent are possible when driving at moderate speeds.
The standard eight-speed tiptronic is specially tuned to the sporty character of the Audi RS 7 Sportback. Drivers can choose between the modes D and S or change gears themselves using the shift paddles on the steering wheel or the selector lever, which sports a unique RS design. While the lower gears of the tiptronic are closely spaced for sporty response, eighth gear is tall like an overdrive to reduce fuel consumption.
The Audi RS 7 Sportback comes standard with quattro permanent all-wheel drive for its decisive advantage in traction and driving safety compared with its two-wheel-drive competitors. At the heart of the quattro system is a center differential with a high locking rate and a separate oil cooler to regulate its temperature. It distributes the power as needed within a wide range between the front and rear axles. In the standard configuration, 60 percent flows to the rear and 40 percent to the front.
An intelligent software solution called torque vectoring supports the work of the differential at the cornering limit with minimal braking of the wheels that are under a reduced load. Audi also offers the optional sport differential for the rear axle, which uses two superposition gears to actively distribute the power between the wheels.
The Audi RS 7 Sportback comes standard with polished, 20-inch forged lightweight wheels in a seven twin-spoke design. The five-door high-performance coupe also rolls on optional 21-inch cast wheels in a choice of three designs.
Powerful brakes are located behind the large wheels. The four internally vented discs feature a weight-saving wave design and measure 390 millimeters (15.35 in) in diameter up front. Pins decouple the steel friction rings from the aluminum brake caps. Black painted six-piston calipers – optionally available in red – grip the discs. Audi also offers optional 420 millimeter (16.54 in) carbon fiber ceramic discs with anthracite gray calipers. The electronic stabilization control (ESC) has a Sport mode and can also be deactivated entirely.
Equipped with the air suspension, which harmonizes perfectly with the dynamic character of a sport coupe, the new RS 7 Sportback is sporty, yet still comfortable. The RS 7 adaptive air suspension lowers the body by 20 millimeters (0.79 in). Adaptive damping, another of the system’s features, adjusts the suspension’s response to the condition of the road, the driver’s style and the mode selected in the Audi drive select system, with which the driver can alter the function of key components in multiple steps.
Audi offers the taut sport suspension plus with dynamic ride control (DRC) as an alternative to the air suspension. It uses steel springs and three-stage adjustable dampers that are connected to one another via diagonal oil lines and a central valve. Another option, which can also be integrated into Audi drive select, is the dynamic steering with its steplessly variable steering boost and ratio. As with the standard electromechanical steering, its characteristics are specially tailored for the RS 7 Sportback.
The body of the Audi RS 7 Sportback includes up to 20 percent aluminum and includes many parts of high-strength and ultra high-strength steels. Its high rigidity is the foundation for the precise handling, excellent workmanship and quiet cabin free of intrusive noise.
The character of the Audi RS 7 Sportback is immediately obvious. A series of specific design details give a sporty edge to its flowing coupe design. These include the distinctive bumpers and high-gloss black protective grille with honeycomb structure at the front of the car as well as add-on parts in matt aluminum. At the rear of the car, which features a power extending spoiler, the diffuser and the two large, elliptical tailpipe trims of the exhaust system catch the eye.
The RS 7 Sportback is available in a choice of ten exterior colors, including the new shade Nardo gray and the exclusive finish Daytona gray, matt effect. Two styling packages – matt aluminum and carbon – further customize the appearance. With these, the front center air inlet also sports a quattro badge. With the carbon styling package, the front splitter and the diffuser are somewhat more boldly shaped. Other options include the exterior mirrors with exposed carbon housings and the all-LED headlights, whose designer trims are tinted for a unique look.
The elegant dynamics carry over to the cockpit of the Audi RS 7 Sportback. The dial instruments have black faces, white scales and red needles. A 3D RS 7 logo in the tachometer is a further accent. The key, the flat-bottomed, three-spoke leather steering wheel, the illuminated door entry sills and the displays for the MMI and driver information system also sport RS badges. The driver information system includes a shift light, which indicates when the rev limit is reached. Displays for boost pressure and oil temperature plus a lap timer round out the RS 7-specific menu.
Colors and materials provide for further differentiation. The footrest, pedals and soft keys in the standard MMI navigation plus terminal shine in an aluminum-look finish. The decorative trim below the retractable monitor sports a piano finish.
Carbon inlays are standard, with four additional materials available as options. The headlining comes standard in black cloth, with options for lunar silver or black Alcantara. Of course, the Audi RS 7 Sportback can also be personalized using the Audi exclusive program.
RS sport seats with pronounced side bolsters, integrated head restraints and RS 7 logos are standard. They are covered in a combination of black Alcantara and leather, and the center sections feature diamond quilting. The seats can also be covered alternatively in high-grade, honeycomb-quilted Valcona leather in either black or lunar silver. Audi offers optional power-adjustable comfort seats with memory function. The two rear seats are powerfully contoured. Luggage capacity ranges from 535 to 1,390 liters (18.89 to 49.09 cu ft) depending on the position of the rear seat backs.
The Audi RS 7 Sportback comes with a generous list of standard equipment, including xenon plus headlights, a tire pressure monitoring system, the parking system plus, three-zone automatic air conditioning, cruise control and the Audi sound system in addition to features mentioned previously. High-end options include a head-up display, a comfort package, the dynamic package and the dynamic package plus.
The Bluetooth online car phone is an ideal complement to the standard MMI navigation plus. Its UMTS module delivers the tailored Audi connect services to the on-board monitor, and a WLAN hotspot connects the passengers’ mobile devices. Topping the range of audio modules is the Advanced Sound System from Bang & Olufsen.
The Audi RS 7 Sportback also leads the pack when it comes to driver assistance systems. One of these is the adaptive cruise control with stop & go function including Audi pre sense front. This keeps the powerful coupe at the proper distance from the car ahead and in many situations can help to avoid accidents or mitigate their consequences.
Audi active lane assist helps the driver to keep the RS 7 Sportback on course. The park assist handles the steering when parking. The night vision assistant with highlighting of detected persons reduces the stress of driving in the dark. Audi side assist and the speed limit display round out the list.
Customer deliveries of the Audi RS 7 Sportback begin in the second half of the year 2013 in Germany. The base price in the home market will be 113,000 euros.
The Audi TT RS: A Pure Driving Machine developing 340 bhp
Neckarsulm – The TT RS has a turbocharged 2.5-liter engine with direct gasoline injection; it produces 250 kW (340 bhp) and 450 Nm (331.90 lb.-ft.) of torque. The blazing five-cylinder engine enables the TT RS to perform extraordinary feats. In conjunction with quattro permanent all-wheel drive and a high-performance chassis, the engine makes the compact Audi TT RS a top-notch sports car – available as a coupé or roadster.
Sporty five-cylinder gasoline engines have a long legacy at Audi. The most famous is arguably the turbocharged 2.1-liter engine in the Audi quattro. The first version, which was launched in 1980, offered an impressive 147 kW (200 bhp). And the Sport quattro from 1984, directly inspired by motorsport, delivered a whopping 225 kW (306 bhp). For 25 years, turbochargers and quattro have been a dynamic formula for success.
Audi has resumed using this recipe. Designed from scratch, the five-cylinder engine combines a turbocharger with FSI direct gasoline injection to elevate the TT RS to a high-performance sports car. The TFSI delivers 250 kW (340 bhp) from a displacement of 2,480 cc (151.34 cu in): a specific output of 100.8 kW (137.1 bhp) per liter.
The power-to-weight ratio is also outstanding. In the case of the Coupé, which weighs in at a mere 1,450 kilograms (3,196.70 pounds), the power-to-weight ratio is just 4.3 kilograms per bhp. The Roadster has a weight of 1,510 kilograms (3,328.98 pounds) and a power-to-weight ratio of 4.4 kilograms per bhp – thanks to its extremely lightweight and largely aluminum body constructed as per the Audi Space Frame principle.
The TT RS Coupé rockets from 0 to 100 km/h (0 to 62.14 mph) in 4.6 seconds; the Roadster needs just a tenth of a second longer. The limited top speed of 250 km/h (155.34 mph) is merely the official figure for both versions; as an option, Audi can increase it to 280 km/h (173.98 mph).
Almost even more impressive is the aggressive pulling power. The maximum torque of 450 Nm (331.90 lb.-ft.) is always available between 1,600 and 5,300 rpm. In addition, the TT RS overtakes without the slightest effort. Last but not least, its engine makes passengers’ skin tingle time and again thanks to its speedy and powerful response, its inspiring free-revving character, and its unmistakably guttural tailpipes: five-cylinder classical music by Audi!
Compact and Lightweight: The Five-cylinder TFSI
As an uncompromising sports-car engine, the 2.5-liter TFSI is ultra-compact. Just 49 centimeters (19.29 inches) in length, it is ideally suited for transverse installation in the TT RS. And its weight of just 183 kilograms (403.45 pounds) also sets a record. The crankcase is made of vermicular-graphite cast iron. This high-tech material unites the utmost in strength with low weight; it has otherwise only been used for the large TDI engines from Audi. Perfectly placed reinforcements enhance the block’s loadability. The lightweight cylinder head, the pistons, and the connecting rod are lightweight as well as high-strength.
The ultra-powerful five-cylinder engine is extremely fuel-efficient, requiring an average of just 9.0 liters/100 km [26.13 mpg] as regards the Coupé (Roadster: 9.1 l/100 km [25.85 mpg]). Switchable flaps in the intake manifold mix the incoming air in a calculated configuration. Injected at a pressure as high as 120 bar by the common-rail system, the gasoline swirls intensely in the combustion chamber – which in turn cools the walls. This subsequently facilitates a compression ratio of 10.0:1, which is very high for a turbocharged engine. Both of the adjustable camshafts, controlled via chains, also enhance charging efficiency with respect to the air-fuel mixture.
The large turbocharger generates up to 1.2 bar of boost pressure. The intercooler, fed air ideally by the lower segment of the single frame radiator grille, reduces the temperature of compressed air by over 80 percent at full load.
When an Audi TT RS driver pushes the standard Sport button on the center tunnel, a flap installed in the left exhaust tailpipe renders the exhaust noise even more robust and intense while boosting engine responsiveness. An optional Sport exhaust system is available with matt black tailpipe trims and sound flap.
For Purists: The Driveline
The Audi TT RS is the first classic sports car in the Audi RS family. Like the RS 4 and the RS 6, the Audi TT RS was developed by quattro GmbH as a pure, no-holds-barred driving machine. A new six-speed manual transmission (option: 7 gear S tronic) conveys the engine’s tremendous power, and permits easy and precise operation thanks to a specially designed shift lever boasting particularly short shift travel. The transmission’s defining characteristics are a high efficiency ratio and a sportily narrow spread of the gear ratios.
The Audi TT RS features quattro permanent all-wheel drive as standard equipment. Its heart lies at the rear axle: an electronically controlled, hydraulic multi-plate clutch. If a situation calls for it, the clutch redirects a majority of the torque input from the front wheels to the rear wheels.
Within milliseconds, a powerful electrical pump in conjunction with an accumulator presses together the clutch’s plates via hydraulic pressure. Additions to the quattro powertrain include a constant velocity joint before the propeller shaft and a compact rear-axle differential – both are heavy-duty components.
The quattro drivetrain grants the Audi TT RS outstanding traction, fascinating dynamics, and superb stability. Winding rural routes or some laps around a racetrack allow the superior handling to shine. The precise and responsive steering, the instantaneous reactions of the chassis, the neutrality at the cornering limit, the grip while exiting a curve, and – time and again – the engine’s thrilling power: every mile in an Audi TT RS exudes the distilled essence of sportiness.
High-tech Excellence from Audi: Chassis and Body
The chassis of the Audi TT RS builds on the cutting-edge foundation of the base TT design. The four-link rear suspension, which handles longitudinal and lateral forces separately, plays a crucial role. The electromechanical steering is highly efficient and the power steering adjusts to the vehicle’s speed. With aluminum in the front and sheet steel in the back, the body’s innovative mixture of materials results in a well-balanced axle-load distribution, excellent crash safety, and the outstanding rigidity which lays the cornerstone for the car’s precise handling.
The standard sports chassis, which lowers the body by 10 millimeters (0.39 inches), features tightly tuned springs and shock absorbers. The optional Audi magnetic ride adaptive damping system allows the driver to select one of two modes for the shock absorbers by simply pushing the Sport button. Dynamic mode enables the TT RS to hug the road; Comfort mode provides a pleasantly balanced ride perfect for long journeys.
The sportiest version in the TT model line boasts 18-inch wheels fitted with 245/45 tires. They are complemented by mighty ventilated disc brakes, which measure 370 millimeters (14.57 inches) in diameter at the front and 310 millimeters (12.20 inches) at the rear. So that heat dissipates quickly, the front friction rings are perforated. They, in turn, are connected by hollow pins to the aluminum brake discs, which are encircled by black four-piston brake calipers made of aluminum and bearing RS logos.
The Electronic Stabilization Program (ESP) can be switched off partially or entirely. In Sport mode, the engine does not intervene to monitor traction and, correspondingly, the brakes engage later than otherwise. In the second mode, the ESP is fully deactivated.
The Face of Power: The Exterior
At just 4.20 meters (13.78 feet) in length, the vigorously compact Audi TT RS hints at its explosive potential from the very first glimpse. The front spoiler tapers downward into a splitter, reminiscent of a racing car. The large and squared air inlets have diamond-shaped inserts. And the high-gloss black single frame grille with a frame in matt aluminum look and the TT RS badge bear the same styling. The xenon plus headlights with LED daytime running lights notify faraway drivers that an Audi TT RS is approaching.
The sides of the vehicle are accentuated by large wheels in 5 twin-spoke design, vigorous side sills, and exterior-mirror casings in matt aluminum look. At the tail end, the two large oval exhaust tailpipes – spaced apart – are encircled by a diffuser insert. Here, too, is a TT RS badge. A stationary rear spoiler is standard, though customers can opt for one which automatically extends and retracts. Thanks to a drag coefficient of just 0.3, the 2+2-seat coupé and the two-seat roadster glide effortlessly through the wind. Audi offers the TT RS in eight colors. Among them are four exclusive options: Daytona Gray, pearl effect; Mugello Blue, pearl effect; Sepang Blue, pearl effect; and Suzuka Gray, metallic. The Roadster’s soft top comes in black or dark gray.
Exclusive Character: Interior and Equipment Packages
The dynamic exterior of the Audi TT RS is matched by the interior. The leather multifunction sports steering wheel has an especially thick rim, is flat-bottomed, and is covered with perforated leather. Integrated in the instrument panel, the driver information system can display boost pressure and oil temperature as well as a lap timer for chronicling feats at the racetrack. The door handles consist of two slim strips – typical of Audi RS models. An automatic climate-control system and the concert sound system are standard, as are an electrohydraulic soft top and an electric wind deflector for the Roadster.
The entire interior is black. The heated sports seats feature an Alcantara/leather combination with silver contrasting stitching and embossed TT RS logos in the front backrests. Additional badges and logos appear on the steering wheel, in the rev counter, and on the door sill trims. The inlays are made from brushed aluminum. Floor mats feature silver piping trim; footrests and pedals are in aluminum look.
Audi offers TT RS customers a diverse range of optional equipment: variably styled wheels measuring 18, 19 or 20 inches in diameter; bucket seats with folding backrests; seat upholstery in Silk Nappa leather with perforations or Fine Nappa leather with special TT perforations; inlays with Ibis White or Phantom Black paint finish as well as matt aluminum-look inlays for the exterior. In addition, there are high-tech navigation and multimedia systems available.
Delivery of the Audi TT RS started in Germany in July 2009 at a base price of €56,750 for the TT RS Coupé and €59.600 for the TT RS Roadster.
Technical highlights of RS models
The RS models from quattro GmbH use a variety of technologies in the quattro powertrain. Longitudinal-engine models are equipped with a purely mechanical center differential that normally distributes the power in a ratio of 40:60 between the front and rear axles. If one axle experiences slip, the differential sends the majority of the torque to the axle with the better traction. The center differential can be combined with the optional sport differential, which actively distributes the power between the rear wheels.
The Audi RS Q3, the Audi TT RS and the TT RS Roadster, in which the engine is mounted transversely, use an electronically controlled, hydraulic multi-plate clutch mounted on the end of the crankshaft for better axle load distribution. During normal driving, the clutch sends most of the engine’s power to the front wheels. If the front axle loses grip, the clutch can transfer torque to the rear axle steplessly.
The crown gear center differential
The compact and lightweight crown gear center differential gets its name from the two special toothed wheels in its interior. During normal operation, it sends the power to the front and rear axles in a ratio of 40:60. It can send up to 85 percent of the torque to the rear and a maximum of 70 percent to the front, if necessary. The distribution of power is broad, fast and homogenous. Torque vectoring is a software solution that complements the work of the crown gear center differential during fast cornering with minimal braking impulses at the inside wheels. The result is sporty, virtually neutral handling with outstanding traction.
The sport suspension with Dynamic Ride Control (DRC)
Audi offers the sport suspension with Dynamic Ride Control (DRC) in the RS 4 Avant and above. It uses steel springs and three-stage adjustable shock absorbers that are connected to one another via diagonal oil lines and a central valve. During fast cornering, the valves regulate the oil flow in the shock absorber of the deflected front outside wheel. This increases the support provided and reduces lateral tilt, thus connecting the car even more tightly to the road.
The wave brake discs
Many RS models use vented and perforated brake discs in wave design. All together, their wave-like outer contour reduces weight by nearly three kilograms (6.61 lb). Stainless steel pins connect the steel friction rings to the aluminum brake caps. This concept borrowed from racing reduces tensions and quickly dissipates the heat. The calipers on the front axle have either six or eight pistons. quattro GmbH also offers optional carbon fiber-ceramic discs for the front or all four wheels.
Still more acuity for the super sports car
· Presenting the R8 family from Audi, overhauled in numerous details
· The new top model R8 V10 plus, with the new 7-speed S tronic for all variants
· LED headlights and indicator lights with dynamic display are standard
Audi has made its R8 high-performance sports car even more attractive and dynamic. The R8 V10 plus is a new top model in the model series, with a totally new 7-speed S tronic. The LED headlights and the new rear indicator lights with dynamicized display are standard equipment on all variants.
4.44 meters (14.44 ft) long, 1.90 meters (6.23 ft) wide and only 1.25 (4.10 ft) meters high (Spyder: 1.24 meters (4.07 ft)) – the broad Audi R8, developed and built by quattro GmbH, stands firmly on the road, ready to pounce. New details lend its design even more acuity. The single-frame grille with the beveled upper corners is painted high-gloss black, with horizontal chrome inserts adorning the struts on the V10 variants. The bumper is also new, with the air inlets bearing three crossbars each. As an option, Audi installs a front splitter made of carbon fiber reinforced plastic (CFRP). The splitter is standard on the new R8 V10 plus.
LED headlights with a new technology are now standard on all variants of the Audi R8. The light-emitting diodes for the high and low beams have been placed above and below the strip-shaped daytime running lights, which are specially actuated to serve as indicators. In addition, static turning lights are integrated in the headlights.
The housings of the outside mirrors and the side blades, the lateral air inlets on the Coupé, are made from CFRP on the new R8 V10 plus top model. In the 10-cylinder variants the blades extend outwards farther than on the V8 and have special edging; small marks of distinction also occur at the sills. The vent louvers next to the rear window have an aluminum look on the R8 V10 Coupé (matt black on the R8 V8 Coupé and R8 V10 plus). As an option, LEDs illuminate the engine compartment; in the R8 V10 plus this illumination as well as a partial CFRP lining for the engine compartment are standard.
The LED lights dominate the rear of the Audi R8. One innovation from Audi is the indicator light with dynamic display at the bottom edge of the lamp – its light always proceeds towards the outside, in the direction the driver wishes to turn. Above the high-gloss black area between the vent openings sits the new badge – the letter “R” resting partly on a red diamond, the Audi Sport signature. The large diffusor, optionally CFRP (standard on the R8 V10 plus), has been pulled far upwards. In all engine versions the exhaust system terminates in two round, glossy tailpipe trim sections, painted black on the R8 V10 plus.
Audi offers the R8 in the two solid colors Ibis White and Brilliant Red, in four metallic shades and with five pearl effect / crystal effect coatings. For the R8 V10 plus a matt effect color is available as an exclusive feature. The side blades on the Coupé come in eight colors, while the soft top of the R8 Spyder comes in black, red or brown.
The R8 embodies Audi’s full expertise in ultra-lightweight design. The aluminum body with the Audi Space Frame (ASF) weighs only 210 kilograms (462.97 lb) on the Coupé, and 216 kilograms (476.20 lb) on the Spyder. The unladen R8 V8 Coupé with manual transmission registers just 1,560 kilograms (3439.21 lb) on the scales, while the open-top sports car weighs 1,660 kilograms (3659.67 lb). The R8 V10 plus, available only as a coupé, brings the needle to 1,570 kilograms (3461.26 lb). Adjustable bucket seats with glass fiber reinforced plastic (GFRP) chassis, less use of insulating materials, special light alloy wheels and chassis components, including the standard ceramic brakes, as well the CFRP add-on parts at the body all contribute to lowering the weight.
On the Audi R8 Spyder the lid on the soft top compartment and the side parts are also CFRP. The elegant, lightweight fabric top, with its largely aluminum and magnesium linkage, is the crowning touch to the ultra-lightweight design. The top opens and closes electrohydraulically in 19 seconds, and during driving at up to 50 km/h (31.07 mph). The heated window pane in the bulkhead between the passenger and engine compartments stands apart from the soft top; the window can be retracted and extended by a switch and also serves as a wind deflector. In case of a pending rollover, two strong, spring-tensioned sections shoot upwards from the seats.
As in car racing, the aerodynamics of the Audi R8 has been optimized for propulsion. The underfloor contains five NACA nozzles, along with two diffusors in the front section, which increase the propulsion at the front axle. The drag coefficient is 0.35 or 0.36 depending on the engine version and body shape; the frontal area measures 1.99 m2 (21.42 ft2).
The engines are assembled by hand. The V8 with 4,163 cc displacement and the V10 with its 5,204 cc displacement are captivating, naturally aspirated heavy-duty engines packed with power. The interplay with the new 7-speed S tronic has reduced CO2 emissions by up to 22 grams/km (35.41 g/mile) and decreased the sprint from zero to 100 km/h (62.14 mph) by three-tenths of a second. Both engines are compact and comparatively lightweight. The crankcase is an aluminum-silicon alloy; the bed plate structure provides high rigidity. The dry-sump lubrication allows low positioning of the engines; the pressure recirculation pump operates load-dependently, for increased efficiency.
The FSI direct fuel injection system allows a high compression of 12.5 : 1. Four adjustable camshafts control the valves. At low load and engine speed, flaps in the intake ducts bring about a precise, cylindrical rotation of the incoming air. The exhaust system is designed for low back pressure. The two tailpipes contain flaps; they open during sharp acceleration to produce a fuller sound.
The 4.2 FSI engine produces 316 kW (430 hp) at 7,900 rpm, with a torque of 430 Nm (317.15 lb-ft) between 4,500 and 6,000 rpm. The unit accelerates the R8 Coupé with S tronic from rest to 100 km/h (62.14 mph) in 4.3 seconds and to a top speed of 300 km/h (186.41 mph) (with manual transmission: 4.6 seconds and 302 km/h (187.65 mph)). For the R8 V8 Spyder the corresponding values are 4.5 and 4.8 seconds, respectively, and also 300 km/h (186.41 mph). On average the R8 V8 quattro as a coupé with S tronic consumes 12.4 liters of fuel per 100 km (18.97 US mpg).
The V10 engine provides a torque of 530 Nm (390.91 lb-ft) at 6,500 rpm, with 386 kW (525 hp) at 8,000 rpm. Its crankshaft is a common-pin design, yielding alternating ignition intervals of 54 and 90 degrees. This design combines maximum rigidity and low weight, while at the same time generating the unique car racing-like sound of the V10.
The Audi R8 V10 Coupé with S tronic accelerates from zero to 100 km/h (62.14 mph) in 3.6 seconds and reaches a top speed of 314 km/h (195.11 mph). With manual transmission the values are 3.9 seconds and 316 km/h (196.35 mph). The R8 V10 Spyder with S tronic completes the standard sprint in 3.8 seconds and has a top speed of 311 km/h (193.25 mph) (with manual transmission: 4.1 seconds and 313 km/h (194.49 mph)). The average consumption rate of the R8 V10 Coupé with S tronic lies at 13.1 liters of fuel per 100 km (17.96 US mpg).
The new top model of the model series is the Audi R8 V10 plus. Developing 404 kW (550 hp), its maximum torque is 540 Nm (398.28 lb-ft) at 6,500 rpm. With S tronic, the R8 V10 plus, available only as a coupé, catapults from zero to 100 km/h (62.14 mph) in 3.5 seconds and achieves a top speed of 317 km/h (196.97 mph); the average fuel consumption rate is 12.9 liters per 100 km (18.23 US mpg). The key data with manual transmission are 3.8 seconds, 319 km/h (198.22 mph) and 14.9 liters (15.79 US mpg).
Two power transmission systems are available for the overhauled Audi R8. The manual 6-speed transmission, with its lever leading into an open stainless steel gate, is standard on the V8 and optional on the V10. The new 7-speed S tronic – optional on the V8 and standard on the V10 – spaces the gears closely in a sporty mode; the final drive position has a wide gear ratio. The dual clutch transmission can be shifted at the selector lever or at the steering wheel paddles; a sports mode is alternatively available. At the press of a button the launch control manages starting at an increased initial engine speed and with optimal tire slip.
The new 7-speed S tronic, with a three-shaft layout, is less than 60 centimeters (23.62 inches) in length. Two multi-plate clutches lying behind one another (a new feature), serve two mutually independent sub-transmissions; gears are shifted directly as the clutches alternately open and close. Gearshifting occurs practically without interruption of tractive power within hundredths of a second, and so dynamically, smoothly and comfortably as to be hardly noticeable.
From the 7-speed S tronic the propeller shaft runs through the crankcase of the engine to the front axle, where a viscous coupling distributes the torque. In normal operation the coupling directs about 15 per cent of the torque to the front axle; when the rear wheels start to spin, a maximum additional 15 per cent flows to the front. A mechanical locking differential operates at the rear axle.
The rear-load distribution of the forces ideally harmonizes with the mid-engined concept of the Audi R8. The axle-load distribution is 43 : 57 (front : rear), with small differences between the individual variants.
The chassis of the high-performance sports car employs technologies from car racing. Double wishbones forged from aluminum guide all four wheels. On the R8 V10 plus the springs and shock absorbers have been specially tuned and the camber values at the front axle adapted accordingly. The Audi magnetic ride adaptive damping is standard on the R8 V10 and optional for the V8 variants; it offers a normal mode and a sports mode. The power steering delivers finely differentiated, super-sensitive feedback, with sporty, direct gear ratios.
The overhauled R8 rolls along on large wheels. The V8 engine versions have the standard wheel dimensions of 8.5 J x 18 at the front and 10.5 J x 18 at the rear, with tire sizes 235/40 and 285/35. On the V10 versions Audi mounts 19-inch wheels of widths 8.5 and 11 inches; the tires come in the sizes 235/35 and 295/30 respectively. The optional wheels have especially attractive designs – polished to a high gloss, with a titanium look or (on the R8 V10 plus) in black gloss.
The steel brake disks of the high-performance sports car are internally ventilated, perforated and joined to the aluminum disk bowls by pins. The new “Wave” design of the disks – the wavy exterior contour – lowers the weight overall by about two kilograms (4.41 lb) compared with round disks of the same dimensions. The aluminum brake calipers operate at the front wheels with eight pistons each, and at the rear wheels with four pistons each. In combination with the 19-inch wheels, Audi can provide optional carbon fiber ceramic brake disks (standard on the R8 V10 plus). The electronic stabilization control system ESC offers a sports mode and can also be fully deactivated.
The Audi R8 is a sports car with excellent practical skills. The front luggage compartment has a capacity of 100 liters (3.53 cubic ft); the Coupé accommodates an additional 90 liters (3.18 cubic ft) behind the seats. The long wheelbase of 2.65 meters (8.69 cubic ft) affords generous space. The interior conveys a car racing atmosphere on the luxury level; its dominant feature is the monoposto – the long arc curve running around the cockpit in the area of the driver.
The flattened rim of the optional, more contoured R8 leather-covered multifunction sports steering wheel bears the new R8 badge, which also appears at the gearshift or selector lever, at the door sill trims, in the instrument cluster and on the start screen of the on-board monitor.
The electrically adjustable sports seats are optional on the V8 engine versions and standard on the V10 variants. Depending on the model variant, the seat upholstery is an Alcantara/leather combination or Fine Nappa; on the R8 Spyder a special pigmentation reduces heating from direct sunlight. Audi also offers optional bucket seats with prominent side sections for better lateral support (standard on the R8 V10 plus).
Numerous control and trim elements shine with subdued chrome strips or with black paint; the needles in the instrument cluster and the shift paddles have been slightly modified. The center console and the handbrake lever are covered with leather, adorned by delicate seams; in the V10 models the molding around the standard navigation system plus is also leather-covered.
With the diamond-stitched, Fine Nappa full-leather equipment level, the seats and the door trim feature quilted upholstery; for the R8 Coupé a quilted Alcantara headlining is also available. More individualistic customers can choose between leather items in different colors, inlays in Carbon Sigma (standard on the R8 V10 plus) and piano finish black. A wide range of design, styling and leather packages from the Audi exclusive customization line is also available.
The R8 V10 and the R8 V10 plus come with the navigation system plus and the Bang & Olufsen Sound System as standard on-board features. Other options for all R8 variants include a high-beam assistant, a stowage package, various travel case sets, a cell phone preparation, with belt microphone and voice control, and the parking system plus with reversing camera.
The overhauled Audi R8 will roll off the line to European customers at the end of the year. The base price is EUR 113,500 for the V8 Coupé, and EUR 124,800 for the Spyder. The V10 variants are listed at EUR 154,600 and EUR 165,900 respectively, while the R8 V10 plus costs EUR 173,200.
Technical highlights of R8 models
ultra lightweight construction from Audi
The models built by quattro GmbH tap the full potential of Audi’s ultra lightweight construction to enhance dynamics and significantly reduce fuel consumption.
The bodies of the Audi TT RS models are made largely of aluminum., whereas the Audi R8 features an all-aluminum body. Thanks to ASF (Audi Space Frame) construction, they weigh little more than 200 kilograms (440.92 lb). The body of the R8 Spyder, furthermore, includes large components made of carbon fiber-reinforced polymer (CFRP). A variety of interior and exterior parts made of CFRP are available for the RS models.
The 7-speed S tronic
The Audi R8 high-performance sports car received a new, tailored dual-clutch transmission as part of the update in 2012. Located behind the mid-mounted engine, the seven-speed S tronic features a space-saving, three-shaft configuration. It comprises two separate gearboxes operated via two clutches. Direct gear changes, which are made by changing the clutch, take just a few hundredths of a second with virtually no interruption of pulling power. Compared with the R tronic used previously, the seven-speed S tronic offers better acceleration while reducing fuel consumption thanks to its tall last gear.
Audi Sport customer racing – The anatomy of a winner
The motorsport professionals at Audi Sport customer racing have two fast cars available for customer teams – the R8 LMS ultra and the racing version of the TT RS. Last season saw the large GT racer score victory after victory.
The close relationship between the Audi R8 LMS ultra and the series-production R8 is the result of a consistent and systematic strategy – suitability for motorsport was in the vehicle specification right from the start of the R8 development program. Romolo Liebchen, who is now head of Audi Sport customer racing, was tasked with safeguarding the necessary potential. He was, for example, able to convince his colleagues in series-production development to adopt double-wishbone suspension design for the rear axle, which offers good setup capabilities for racing applications. There were also a number of issues to be agreed with Audi Design, primarily around the rear end. The outcome of this discussion was a road-going sports car of dynamic elegance and with excellent motorsport qualities.
The finished production model delivers more than 50 percent of the parts for the race car. This unusually high proportion underscores the sporting competence of the series-production R8 and, at the same time, keeps a lid on the costs for the customer compared with some competitors. Audi Sport customer racing offers the R8 LMS ultra for 339,000 Euros plus tax.
It is not only development, but also production of the racing and road-going R8 that are closely intermeshed – the entire team at quattro GmbH is incredibly committed and enthusiastic. Specialists in bodyshell production at the Neckarsulm plant extract the Space Frame of the R8 LMS ultra from the production process and equip it with special fixing points for the running gear, because the race car sits a good deal lower than the road car. The underbody is also fitted with fixing points for the pneumatic jack; a steel safety cage is welded into the cell. After that, the bodyshell goes through cathodic dip coating in the same way as the regular R8.
Because of the cage, the body-in-white of the Audi R8 LMS ultra is 56 kilograms heavier than that of the road car; but, when finished, it has a curb weight of just 1,250 kilograms. Its outer skin, except for the roof, is made from carbon-fiber reinforced polymer (CFRP); it is 80 millimeters wider than the series-production model and has a larger rear spoiler. The Audi Sport customer racing workshop at the satellite assembly facility in Heilbronn-Biberach is left with a lot of additional equipment to install – from the air conditioning, through the insulating materials to the many components of the vehicle electronics system. Not including the engine, the parts list consists of around 4,000 components; 1,000 less than the series-production R8. Two specialist assembly technicians work for around ten days on an R8 LMS ultra.
Aside from the reinforced bearing shells, the 5.2-liter engine is directly off-the-shelf. Even the intake tract is largely series-standard; all it requires is space for the two airflow restrictors that limit the output in line with regulations. The water cooler is somewhat set back in the chassis to ensure that the car remains drivable after a mild collision. The engine masters all the demands of racing service with ease – including 24-hour races with distances of around 4,000 kilometers, more than half under full load. The V10 is generally able to survive the season without overhaul.
When it comes to the transmission, the Audi R8 LMS ultra plows its own furrow. The specially developed racing transmission is equipped with a pneumatic manual shift controlled by the driver via steering wheel paddles. In line with regulations, the power flows only to the rear wheels. The wheel mounts and steering are from the series-production vehicle, while the adjustable anti-roll bars, springs and dampers are racing parts. The racing brake system features steel discs that allow the pads to be changed very quickly; the wheels are 18 inches in diameter.
The fire extinguisher system comes from the Audi Le Mans prototype; it is more expensive than conventional systems, but also considerably more effective. The racing seat is a brand new design made from CFRP; like the high-speed refueling system, it significantly exceeds the required safety standards. The CFRP doors reduce weight, while increasing passive safety with their energy-absorbing impact foam.
Two dozen new Audi R8 LMS ultra are being built for the 2013 season, increasing the number of R8 GT racing cars ever built to 120. A few weeks ago, quattro GmbH completed the 100th R8 LMS ultra. The race car is receiving a host of improvements for the 2013 season. They impact the aerodynamics, front-suspension pivot points and the wheels.
The new GT race cars are continuing in some highly successful tracks. From 2009 to 2011, the R8 LMS won 13 international titles, with the last season adding a further five new championships to the list. In 2012, no competitor scored more GT victories than Audi. There are no less than 18 successes on the list, including four achieved at tough endurance races – the 24-hour races at the Nurburgring, in Spa and Zolder, as well as the 12-hour race in Bathurst, Australia.
Customer sport with the R8 LMS is an international business. In 2012, Audi launched a single-brand trophy in China, the R8 LMS Cup. The brand is also active in North America, where January 2013 saw the revised Audi R8 GRAND-AM get the new season off to a great start – with victory in the GT category at the 24-hours of Daytona. Audi Sport customer racing supports ist customer teams worldwide – the parts store has 4,650 entries; last year, 47,862 parts were dispatched in 817 deliveries to 42 customers. Outside of the regular racing business, Audi customers can also book training courses with the R8 LMS ultra; the three-stage program extends all the way to participating in an actual race on the Nurburgring.
The TT RS has been part of the customer sport activities since 2011. The compact race car is specifically adapted for the SP4T class or the VLN Endurance Cup – it is a specialist for the Nurburgring Nordschleife. The five-cylinder turbo engine is derived from series production and generates 280 kW (380 hp); the driver operates the racing transmission sequentially. The car is front-wheel drive and, thanks to its sophisticated kinematics and efficient aerodynamics, the TT RS boasts outstanding traction and excellent handling.
Audi exclusive – Equipment made-to-measure
For demanding customers looking for their personal expression, quattro GmbH offers an extremely broad range. Be it color, leather or trim; bodyshell, wheels or interior – when it comes to individualizing cars, quattro GmbH offers the biggest range in the competitive field with its Audi exclusive program.
The exterior choices include around 100 paint colors and a whole host of styling packages that are designed specifically for the respective model range. They also include off-road packages for the Audi Q3 and Q5. Customers who place even greater value on their very own personal expression can order paintwork in the color of their choice, mixed specifically for them. For the Audi R8 and even for other models, too, there are a range of matte paint finishes that achieve a spectacular effect. The range of alloy wheels – a bestseller for quattro GmbH – is growing constantly and extends all the way to the titanium-look 21-inch wheel.
The interior program consists of 16 interior colors, two leather qualities, Alcantara and nine carpet shades. For the seats, almost all options can be individually configured and accented with contrasting stitching; the color of the leather is also fully open to choice. To complement the leather, quattro GmbH offers exclusive trim inlays – in piano lacquer, metal and fine wood veneer. For the full-size models, the Audi exclusive program encompasses fine solutions for the headliner and instrument panel; the flagship A8 offers features like a cool box, a folding table and fully adjustable reading lights in the rear.
In fall 2009, quattro GmbH brought out its first limited special edition under the name Audi exclusive concept. The Audi Q7 V12 TDI with 368 kW (500 hp), was painted in pearlescent Ipanema Brown, a shade that seems to shift constantly between brown and bronze. Its leather upholstery was in two colors – the seats and door panels in Alabaster White, the instrument panel and center tunnel in Chestnut Brown. The trim was made from American walnut with inlays in smoked oak; even the floor of the luggage compartment and the backs of the rear seat backrests were clad in this fine veneer.
In 2011, the line was continued with the A8 L W12 Audi exclusive concept. The Monsoon Gray exterior of the Audi flagship with 368 kW (500 hp) enveloped an interior that was dominated by cognac leather from Italian furniture studio Poltrona Frau; it was a hide with a particularly supple, even and natural finish. The trim elements were made from natural olive ash; its gray/brown tone harmonizing perfectly with the Granite Gray cording on the seats.
The most recent model in the range is the SQ5 TDI Audi exclusive concept with 230 kW (313 hp) presented in fall 2012; its Ara Blue crystal paintwork has an amazing depth of finish. The interior is one of powerful contrasts – the upholstery is in black, accentuated by white stitching, while the center panels are clad in woven leather. The headliner and door inserts, on the other hand, gleam in snow white.
The trim elements are made from grained ash veneer, with the grain beautifully and powerfully accentuated using a special processing technique.
