We saw it in Detroit, and now it's Europe's turn to ogle the spectacular V12 TDI-powered Audi R8. When it premieres in Geneva tomorrow, it will do so with a new name: the R8 TDI Le Mans. The car's 6.0-liter oil burner powers the concept to the tune of 500 horsepower and an epic 1,000 Newton-meters (737.56 lb-ft) of torque.
The R8 TDI's beastly engine is already Euro 6-compliant thanks to a special catalytic converter downstream of the oxidizing catalyst and particulate filter. Small quantities of "AdBlue," are injected into the exhaust system to split the nitric oxide into nitrogen and water. And with cleanliness comes goodness -- a 4.2-second run from 0-62 mph and a top end over 186 miles per hour. Is this the next evolution of the supercar?
