The Audi R10 TDI (Turbo Direct Injection) is a sports prototype designed and built by Audi in partnership with Dallara. Built to the Le Mans Prototype 1 (LMP1) regulations, the R10 was highly successful throughout its career; the R10 became the first diesel-powered car to win the 24 Hours of Le Mans in 2006, in what would be the first of three 24 Hours of Le Mans wins. Unveiled to the public on 13 December 2005 in Paris, the R10 would go on to win the 2006 24 Hours of Le Mans just 200 days later.
The R10 was eventually replaced by the R15 TDI at the conclusion of the 2008 American Le Mans Series. Colin Kolles of ByKolles Racing (known then as 'Kolles') fielded the car for two more years at Le Mans and for a single year in the 2009 Le Mans Series.
