Developmental history

On July 7, 2024, the Automobile Club de I'Ouest formally announced that 2025 would be the first year of the third generation Le Mans Prototype 3 (LMP3) cars using the previously announced, Oreca built, Toyota V35A V6 twin-turbocharged engines.^[5] All four previous constructors were retained for the new regulations.^[2] Upgrades to the car's cooling system were required due to the new twin-turbo engine.^[6] At the European Le Mans Series 4 Hours of Spa, Ligier was present to showcase the new car with changes to its front end to increase airflow to the rear.^[7]

Olivier Pla tested the car at Magny-Cours and Barcelona, completing around 400 km (250 mi) over six test days. Test results were positive overall, with the new cooling system working well, however there was an issue with downshifting that was discovered and fixed with help from Oreca.^[7]
