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.[3] All four previous constructors were retained for the new regulations.[2] Upgrades to the car include a completely new cooling system, engine cover and new rear bodywork kit as a result of the new engine.[4][5] New dampers from KW, were also added to improve performance.[6]
Testing started in July 2024, at Estoril with TCR driver Quique Bordas, and continued at Barcelona and Portimão.[7] Wayne Boyd also tested the car in September.[6] Straight-line testing was conducted at Beja Airport with more track testing at Portimão and Estoril. Stéphane Chosse, the CEO of ADESS, reported that aero stability had improved throughout over 3,000 km (1,900 mi) of testing before homologation.[8] In January 2025, ADESS inked a deal with Nielsen Racing and signed Colin Noble as its factory development and race driver.[9]
