Audi has done a great job this season by winning two major 24 hours races with two different brand new cars. First was the Nurbrugring 24 Hours with the Audi R8 LMS ultra in May. A month later was Le Mans with the Audi R18 e-tron quattro. The cars were at the Norisring DTM weekend doing some demo laps celebrating these two maiden wins. Marcel Fassler drove the LMP1 hybrid racer, while Markus Winckelhoc with the R16 GT3. Rainy weather but the big crowd and German fans really enjoyed it.
