Audi is ending an era. On Saturday, November 19, not only the current season of the FIA World Endurance Championship (WEC) will end in Bahrain but also Audi ceasing its Le Mans sports prototype program after 18 years. Audi’s sports prototypes, from the Audi R8, the Audi R10 TDI and the Audi R15 TDI to the Audi R18, have shaped an entire racing era. They represent one of Audi Sport’s most successful periods and are symbols of the technical progress achieved by the brand with the four rings.
