ALL AUTOCARS

Power for the concept comes from the automakers race-derived 6.0 liter V12 diesel motor. The engine produces 500 horsepower and 738 pound-feet of torque.

Audi would equip the R8 with a diesel engine for the 2009 model year, although Audi's TDI V8 was assumed to be the leading candidate.

Other highlights of the show car include a glass roof, an increased use of carbon fiber, revised front and rear aprons, and larger air intakes all around.
