Audi Cross Coupe quattro: The Drivetrain
The Cross Coupe quattro is powered by an all-new 2.0 TDI diesel engine, the first example of the new generation of four-cylinder TDI engines in the Volkswagen/Audi Group. This 150 kW (204 bhp) power plant marries distinctly sporty characteristics peak torque is 400 Nm between 2,000 and 3,500 rpm with a high level of refinement and an impressive degree of economy and efficiency. The compact yet powerful sports car needs just 5.9 litres of diesel for 100 km. The fuel/air mixture is prepared by a common-rail system of the latest generation, which is also employed by Audi in the V6 TDI engines. It has a high-pressure pump and common manifold (rail) for each of the four cylinders. The maximum injection pressure is 2,000 bar. The high injection pressure provides for even finer atomisation of the fuel and thus for a better mixture and more efficient combustion. Piezo injectors allow the number of injection sequences per working cycle to be varied almost at will. A strategy that provides for both softer combustion and for lower untreated emissions in other words, top engine acoustics and at the same time extremely low overall emissions. Without doubt, the 2.0 TDI engine is the current benchmark in its class in both disciplines. More innovative technology on board reduces overall emission even further. For example, the new engine is not only combined with a diesel particulate filter, but also employs the Bluetec injection system to reduce nitric oxides effectively. The heart of the Bluetec technology is a special catalytic converter downstream of the oxidising catalyst and the particulate filter. The second component in the system is an additional tank containing a watery solution of carbamide (urea). Small quantities of the solution, known as “AdBlue”, are injected into the exhaust system. The hot exhaust gases break the solution down to form ammonia, which splits the nitric oxides into nitrogen and water. The system will remain effective for the entire service life of the vehicle. With such extremely clean Bluetec diesel engines, Audi is continuing its tradition of leading from the front in matters of diesel engine technology. In 1989 it was the Ingolstadt brand that developed direct injection technology. Since then the diesel engine has become around 30 percent more economical and the Euro 4 European emission standard has reduced particulate emissions by 93 percent. Long before it came into force, Audi had models on the market that satisfied this standard, even without a particulate filter. This equipment enables the Audi Cross Coupe quattro even today to meet the most stringent regulations currently known, the Euro 6 standard and the strict US emissions legislation. The quattro permanent four-wheel drive system provides for power transmission what else would you expect from an Audi with a powerful engine and offroad qualities? An electronically controlled viscous clutch provides variable power distribution between the front and rear wheels, just as it does on the Audi A3 quattro and the Audi TT. The sporty Audi S tronic direct-shift gearbox enables the driver to execute a gear change within a fraction of a second without a clutch pedal. If he wants, the gearbox will make all gear changes fully automatically. And if he wants to change gear manually, he can do this with the shift paddles in the steering wheel. The newly designed selector lever with integrated control knob for selecting gear is a further development of the shift-by-wire system.
