A sports prototype racing car built by the French automobile manufacturer Peugeot to compete in the 24 Hours of Le Mans endurance race, starting in 2007 and eventually winning in 2009. This effort, in development since 2005, was publicly unveiled on 15 June 2005. It first competed against the Audi R10 TDI, becoming the second diesel engined sportscar from a major manufacturer, and then against the Audi R15 TDI. This was Peugeot's first Le Mans effort since the end of the Peugeot 905 project in 1993.
