Rules 2014

Cars entered in the European Le Mans Series fall into two main categories, prototypes and GT. Each is sub-divided in two categories: LMP2 (Le Mans Prototype 2) and LMPC (Le Mans Prototype Challenge) and GTE (Grand Touring Endurance) and GTC (Grand Touring Challenge), the latter being a new category which aims to be a launch pad for competitors taking part in other GT championships but who wish to move towards endurance racing.

Therefore, in order to offer teams the opportunity to recoup their investments and defray operational costs by entering complementary events, the ACO has decided to expand the eligibility of the European Le Mans Series GTC class to GT3 cars. Since 2013, only cars homologated by the FIA GT3 are eligible.
Below are the main technical specifications for each category. In order to balance power output between different makes, cars are equipped with air restrictors. Their diameter is varied according to the engine configuration, induction system, the type of fuel used for Prototypes, and weight for GT cars.
