After a long enduring domination at Le Mans by Audi since 2000, Peugeot has beaten Audi in 2009 where the R15 was introduced.
Now in 2010, Audi strikes back and brings an evolution racer of the R15 to the starter grid, called Audi R15 "plus".
Efficiency was a focal point during the R15 TDI evolution project - particularly in the complex area of aerodynamics. "This year, the Le Mans regulations prescribe air restrictors with a smaller diameter and reduced supercharging pressure for diesel-powered vehicles," says Dr. Martin Mühlmeier, Head of Technology at Audi Sport. "Due to the reduction of engine power as a result of the regulations we have tried to make the car's aerodynamics even more efficient than before and to improve the Cd value and downforce parameters."

Late changes in regulations that were announced in November 2009 forced Audi to completely modify the front section of the R15 TDI. Consequently, the diesel race sports car has a new, distinctive face featuring a split nose.
