Audi R8 V12 TDI concept

Audi presented the R8 V12 TDI concept in Detroit in early 2008. A few weeks later, the R8 TDI Le Mans was exhibited at the Geneva Motor Show. Both show cars were powered by a six-liter V12 TDI. The 368 kW (500 hp) engine, developing 1,000 Nm (737.56 lb ft) of torque at 1,750 rpm, accelerated the two-seater from naught to 100 km/h (62.14 mph) in 4.2 seconds and up to a top speed of over 300 km/h (186 mph). The fuel consumption of the concept car was calculated as less than 10 liters per 100 km (23.52 US mpg).
