The European Le Mans Series is a European series of endurance races reserved for cars such as "Le Mans Prototypes" and "Le Mans Grand Touring". The ELMS presents three different categories: LMP2, LMP2 Pro/Am, LMP3 and LMGT3.
LMP2
The category below the top LMH class of the FIA World Endurance Championship, LMP2 is a key part of the “Endurance" family which allows teams, as well as drivers, to gradually progress to the highest level. The "Le Mans Prototype 2" (LMP2) class is reserved exclusively for privateer teams independent of constructors and/or engine suppliers.
LMP2 cars have similar characteristics to LMH (carbon monocoque chassis) while respecting strict cost criteria: the price must not exceed €483,000.
The four constructors who supply chassis for the cars that will compete in the LMP2 category are: Dallara, Ligier Automotive, Oreca, and the joint-venture Riley Tech/Multimatic.
In the European Le Mans Series, FIA World Endurance Championship and Asian Le Mans Series all LMP2 cars will be equipped with Gibson Technology engines. The 4-litre V8 engine, which was unveiled at the 2016 24 Hours of Le Mans, delivers around 600bhp.
Cosworth Electronics will be the single electronics supplier. The unique Cosworth electronic unit will also provide a more efficient level of service (equipment, etc.) while enabling the performance of the engines run in the ELMS, FIA WEC, and Asian LMS and in the American series to be managed.
The weight and dimensions of the 2017 LMP2 cars have changed from the closed cockpit cars run previously with the maximum measurements of the new cars being longer, narrower, slightly taller, and 30kg heavier.
Each driver lineup must be made up of at least one "Silver" rated driver. Two Platinum drivers cannot be entered in the same lineup.
LMP2 – 1st and 2nd LMP2 competitors will be invited to the next 24 Hours of Le Mans.

LMP3
The LMP3 class was introduced by the Automobile Club de l’Ouest (ACO) in 2015 and 2025 will mark the introduction of the third generation of LMP3. Four manufacturers have been selected to help the ACO take the class forward: Ligier, Duqueine Engineering, Ginetta and Adess.
Competitive cars, a top-flight sporting programme, an affordable budget, a straightforward mechanical set-up and technology within everyone’s reach will continue to form the backbone of the series. LMP3 was designed as a training ground for endurance racing, an arena in which drivers, team members, engineers and mechanics can hone their skills and prepare for the 24 Hours of Le Mans and the FIA World Endurance Championship.
