The FINANCIAL — Audi, the inventor of TDI, blazes a trail in the field of engine manufacture. At the 27th annual Lake Wörther Tour being held at the end of May in the Austrian province of Carinthia, the brand behind the four rings is showcasing this technology's potential with a sensational study.
The two-liter TDI unit under the bonnet of the Audi A3 TDI clubsport quattro delivers 165 kW (224 hp) and musters up 450 Nm (331.90 lb-ft) of torque – the sort of pulling power normally associated with a sports car. The show car races from 0 to 100 km/h (62.14 mph) in just 6.6 seconds and attains a top speed of 240 km/h (149.13 mph).
The Audi A3 TDI clubsport quattro projects its power with supreme confidence – both acoustically courtesy of its sonorous exhaust and visually with a series of exclusive parts mounted on the body and in the interior. Exterior components such as the large DTM-look rear spoiler and the bolt-on wheel arch extensions give the car a dynamic air, while the racing bucket seats and open gear lever gate in aluminum form the highlights of the interior.
The show car is a true high-tech sports car. The drive power is directed to the 20-inch wheels via a six-speed transmission and the quattro all-wheel-drive system. At the front wheels, stopping power is provided by six-piston brake calipers and ceramic discs. The Audi drive select driving dynamics system allows the driver to vary at will the throttle response characteristic, the exhaust sound, the level of power assistance for the steering, the cut-in thresholds for the ESP stabilization system, as well as the operating mode of the dampers. The dampers deploy Audi magnetic ride technology, enabling them to react to changes in the driving situation with lightning speed.
Audi – the trailblazer of engine manufacture
Audi is the trailblazer of engine manufacture. Since their debut back in 1989, the TDI engines have long since established themselves helped by their powerful, refined and efficient character. The triumphant advance that the diesel-powered Audi R10 TDI racing car has been enjoying for two years now in the Le Mans 24 Hours and in the American Le Mans Series is clear testimony to this technology's tremendous potential.
The engine in the R8 TDI Le Mans study is closely related to the diesel race engine technically speaking – the high-performance sports car is equipped with a six-liter V12 power unit whose output of 368 kW (500 hp) and torque of 1,000 Nm (737.56 lb-ft) are good for a top speed comfortably in excess of 300 km/h (186.41 mph). The R8 TDI can also be seen at the Lake Wörther Tour, as the major annual gathering of horsepower-happy Audi and VW enthusiasts is known. Audi has already transferred the superior power of the TDI engines into its road-going cars: the TT and TT Roadster both feature a mighty two-liter unit generating 125 kW (170 hp) and 350 Nm (258.15 lb-ft) of peak torque, coupled to the quattro all-wheel-drive system. As is plain to see, Audi continues to build on its lead in the technology stakes.
