The Formula Le Mans car is built by French manufacturer Oreca and known as the FLM09. The chassis is based on Oreca's LC75 LMP2 chassis, while the car's carbon fiber and kevlar bodywork is a simplified version of the LC75's design. All FLM09s use a production-based General Motors small block LS3 V8 which produces approximately 430 horsepower (440 PS). Transmissions are supplied by Xtrac and feature a six-speed sequential transmission operated by paddle shifters. Engine management is regulated by Magneti Marelli. All cars run on Michelin slick tires based on their LMP tires. Reinforced carbon-carbon disc brakes are supplied by Brembo.

In order to accommodate endurance races in 2010, Oreca also offers an endurance upgrade for the FLM09 which adds an air restrictor to the engine to increase reliability as well as slowing the car in comparison to LMP2 category cars.



American Le Mans Series

On August 16, 2009, the International Motor Sports Association announced a reorganization of the class structure of the American Le Mans Series, creating a new category known as Le Mans Prototype Challenge. This class will utilize the Formula Le Mans ruleset similar to the Le Mans Series, although LMP Challenge cars will compete in all nine American Le Mans Series events.[2] American Le Mans Series regular Intersport Racing became the first North American team to purchase an FLM09, allowing the team to progress drivers from IMSA Lites, through LMP Challenge, and into their LMP1 category entry.[1]
