quattro GmbH 2013

Editorial Franciscus van Meel

Dear reader,

We are celebrating a special anniversary this year at quattro GmbH. For 30 years, our company has stood for high performance and high-tech, in short, for the fascination of quattro. The magical word quattro encapsulates not only an ingenious technology; for us and our fans it also means a dynamic approach to life within the four rings.

As a subsidiary of AUDI AG, we cover three areas of business. The first is the development and construction of Audi’s high-performance models, i.e. the RS and R8 types. The second field of activity encompasses vehicle individualization and accessories. And the third, and most recent, is customer motorsport. We are expanding our success in all three of these areas at an astonishing rate.

Since 1996, quattro GmbH has produced around 75,500 high-performance automobiles, with recent years in particular seeing a further significant rise in output – from 2,500 cars in the year 2000 to around 11,500 in 2012. In the same year, we individualized 160,000 cars and sold almost 2.5 million accessories.

We have also put our collective foot to the floor in Audi Sport customer racing.

Our car, the R8 LMS ultra and its predecessor have chalked up more than 150 victories on four continents in the space of three years. Its wins in 2012 included the 24-hour races on the Nürburgring and in Spa-Francorchamps.

All these successes motivate us to become even stronger. With the RS and R8 models, we are aiming for sales of 15,000 units this year. The engine of this growth is our new high-performance automobiles – the RS 5 Cabriolet, the RS 6 Avant, the RS 7 Sportback and the RS Q3. With a total of eight RS models, we are now presenting our greatest lineup ever. In order to offer it to our customers around the world, we are expanding our activities in the US, China, Russia and the Middle East considerably.

At quattro GmbH we feel we are well prepared for the future. In this booklet, we would like to provide you with an insight into our company. Take a thrilling ride through the dynamic world of quattro GmbH.

Kind regards,

Franciscus van Meel

First RS model in the Q series: Audi RS Q3

“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.

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.

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.

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.

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.

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 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.

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 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.
