The first details of the joint draft technical regulations for Le Mans Daytona h (LMDh) have been released. LMDh cars will be eligible to race in the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship.
The LMDh platform will be a common car created by ACO-IMSA, based on a cost-capped car with the same spine as LMP2 racers, and only mainstream automotive manufacturers can homologate an LMDh car.
They will feature a manufacturer-branded and stylized bodywork, a manufacturer-branded engine, a common single-source rear-wheel-drive hybrid system, and a minimum homologation period of five years.
The basic rules consist of a minimum car weight of 1,030kg, 500kW peak of combined power, one bodywork package with identical aerodynamic performance, tires supplied by Michelin, and a global BOP to harmonize the overall performance of LMDh and LMH cars.
LMDh race cars are expected to be introduced in 2022 but may be delayed due to the COVID-19 pandemic.
Final regulations are expected to be released before the Le Mans 24 Hours in September 2020.
Ed Bennett, CEO of the International Motor Sports Association (IMSA), said, “These regulations provide a roadmap for manufacturers and constructors to embark on the design process for new LMDh race cars that will revolutionize the top category of premier sportscar racing around the globe.”
