RED MENACE: Audi R8 TDI Le Mans infiltrates Geneva

The Audi R8 V12 TDI concept that made such a splash in Detroit has a fraternal twin, and it's headed to Geneva. Finished in Brilliant Red paint and dubbed the R8 TDI Le Mans -- the association with the fabled endurance race carries a lot more weight on the Continent -- the car arrives in Geneva with the same impressive spec sheet as its silver counterpart. A 6.0L V12 TDI is crammed in the space behind the R8's passenger compartment. It packs a bit of a punch, too -- 500 horsepower and enough torque (737 lb-ft) to alter the earth's rotation allow for a 0-62 mph time of just 4.2 seconds and a 186 mph top end. That's Euro 6-compliant power, too. Clean and mean -- emphasis on the mean.
