Audi R18
Audi R18-based R20 is the latest supercar to bring the Le Mans experience to the road Audi

The Audi Sport racing program has won 11 of the last 13 grueling 24 Hours of Le Mans endurance races. Celebrating a remarkable dynasty, the automaker from Ingolstadt is slated to unveil an extreme R18 inspired Le Mans road car.

According to Car and Driver, a source from inside Audi has spoken out, sharing some interesting details on the project, internally known as "Scorpion":

"It wouldn't make sense to use anything but the R18′s racing engine in the Scorpion," said the source.

The exotic R18 racing engine is a 3.7 liter V6 TDI engine with a front mid-mounted hybrid system. In race car form, the engine intakes are restricted. Performance specs are rated at more than 500 hp and 625 lb.-ft. of torque. That said, the automaker will likely crank up the power even more for the ultra-exclusive production car. Industry observers believe that the hyper-Audi will not be unveiled until 2017.

Despite wild success with its main line of mass production models, Audi research and development chief Wolfgang Dürheimer believes that a Le Mans road car can add luster to the brand in order to raise its profile and keep its motorsports efforts relevant.
