With the Audi R18 e-tron quattro, the brand with the four rings scored the first victory for a hybrid racecar in the 24 Hours of Le Mans. Furthermore, Audi won the new FIA World Endurance Championship (WEC) and is thus the first World Champion in history with a hybrid sports car. Audi starts the WEC as defending champion in 2013. Audi Sport Team Joest competes with a brace of further developed Audi R18 e-tron quattro prototypes. For the 24 Hours of Le Mans and in the WEC race at Spa, which once again acts as a “dress rehearsal” for Le Mans, an additional R18 e-tron quattro joins the grid.
