The Michelin Le Mans Cup is reserved for cars conforming to the current FIA GT3 homologation regulations as well as the LMP3 in conformity with the ACO LMP3 2026 regulations.
Michelin, the title sponsor of the series, will be the exclusive tyre supplier and TotalEnergies will be the official fuel supplier.

LMP3
The LMP3 class was introduced by the Automobile Club de l’Ouest (ACO) in 2015 and in 2025 the third generation of LMP3 was introduced. 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.
