2021 FIA World Endurance Championship

The championship will introduce the Le Mans Hypercar category as a replacement for the Le Mans Prototypes.[14][15] Manufacturers will be free to build and enter bespoke designs without homologation requirement or cars based on existing road-going models subject to a homologation requirement of building at least twenty road-legal models over a two-year period.[16] The cars will have a minimum weight of 1,040 kg (2,290 lb) and may use a hybrid powertrain. The power output will be fixed at 750 bhp (560 kW) to achieve a benchmark lap time of three minutes and thirty seconds at the Circuit de la Sarthe.[16] Cars that use a hybrid powertrain will not be permitted to derive more than 270 bhp (200 kW) from the hybrid system. A Balance of Performance system modelled on the system used by the GTE class will be applied to ensure parity between hybrid and non-hybrid models.[16] Manufacturers will be given greater freedoms in designing the bodywork of Hypercars compared to Le Mans Prototypes provided that bodywork styling does not affect safety standards.[16]

LMP2 cars would receive a power decrease of 40 horsepower, to 560 horsepower, and a specification tyre would be introduced in the class, ending the tyre war between Goodyear and Michelin.[17]

At the World Motorsport Council on March 6th 2020[18], details emerged on the previously announced LMDh category, in that it would join Le Mans Hypercar as the top category in the series. LMDh will be a common platform to both the FIA World Endurance Championship as well as the IMSA WeatherTech SportsCar Championship, and will be designed to match performance levels with the Le Mans Hypercar class.
