AUDI R10

THIS CAR revolutionised modern endurance racing. Its 5.5-litre twin-turbo V12 was the first diesel-powered car to win at Le Mans. It clocked three victories between 2006-08, with its final win being the last time a V12 won Le Mans outright. Run at a cost of US$15m a year, it was Audi’s most expensive racing project ever.
