The first car designed, built and managed entirely by Oreca, the 01 of the LMP1 class was presented in 2009 and took its first steps in April of that year before participating in the European Le Mans Series and the 24 Hours of Le Mans. The 01 was the best private car, also ranking twice in the top five at Le Mans (fifth in 2009 and fourth in 2010). Equipped with the 650 horsepower AIM V10 engine, the Oreca 01 soon became an outsider against the greats, also winning the 6 Hours of Silverstone and getting several pole positions. It was also used in the Asian Le Mans Series and in the ALMS, where it obtained a fifth place at Road Atlanta behind Peugeot and Audi. The 01 was the basis for the following cars: 03, 03R, 05 and 07.
