ORECA (Organisation Exploitation Compétition Automobiles) is a French racing team, founded in 1973 and run by Hugues de Chaunac, former team manager of F1 team AGS. Oreca has had success in many areas of motorsport including Formula Three where drivers including Alain Prost, Jacques Laffite and Jean Alesi have won the French Formula Three Championship for the team a record 11 times.
Since the early 90s the team has concentrated on running sports cars and GT cars running a BMW operation in the French Supertouring Championship, winning the FIA GT Championship and the Le Mans 24 Hours in the GT2 class with a Chrysler Viper GTS-R and overall for Mazda 787B in 1991, on their second attempt and first after a decade; preparing the Renault Clio S1600 for rallying and winning the ice racing Andros Trophy with a Toyota Corolla driven by Alain Prost. More recently, Oreca have assisted Renault in building the new Megane V6 for the Renault Eurocup Megane Sport and fielding an Audi R8 in the 2005 Le Mans 24 Hours with support from Audi France. Also for 2006 Oreca ran the Saleen S7R in the Le Mans Series. The Oreca Saleen S7R had already won the 2006 Spa-Francorchamps Le Mans race.
Oreca worked closely with Dodge on the Dodge Viper Competition Coupe, producing well over 100 customer cars in the period 2006–2007 to GT3 specification.
In 2008 Oreca became a manufacturer, producing the Oreca 01. The 01 was made for the P1 category and was first raced at the 2009 1000 km of Spa with two entries.
During 2009 Oreca started producing the Formula Le Mans 'FLM09'. This was initially run in its own series named the Formula Le Mans Cup until 2010 when it was adapted to allow it to be run three other endurance series including the American Le Mans Series which gave the car its own category (LMPC). The idea was to give an affordable platform for smaller teams to get into endurance racing.
Oreca entered a customer spec Peugeot 908 HDi FAP with 'Semi-works' help for the 2010 Le Mans 24 Hours, as well as for the rest of the Le Mans Series races, taking overall honours at the Autódromo Internacional do Algarve and the overall championship ahead of the factory Peugeot teams.
In 2011, Oreca won the 12 Hours of Sebring race despite still using a 2010-spec car versus the new for 2011 Peugeot 908s. They also introduced their new chassis to accommodate the new regulations for 2011, the Oreca 03. The 03 is a P2 class car as opposed to its predecessor, the Oreca 01, which ran in the P1 class.
In 2012 Oreca was selected to run the Toyota TS030 Hybrid LMP1 car with support from Toyota Motorsport GmbH in the FIA World Endurance Championship (including the 24 Hours of Le Mans). The car showed promising speed but did not finish at Le Mans due to a large crash involving one car and mechanical problems sidelining the other.
