FIA World Motor Sport Council approves changes to Le Mans Hypercar regulations

The FIA World Motor Sport Council have approved recent adjustments made to the Le Mans Hypercar technical regulations that will replace LMP1 for Season 9 of the World Endurance Championship.

In a release detailing a number of decisions made by the World Motor Sport Council across a range of motorsports, it revealed how the recent changes to the Le Mans Hypercar (LMH) technical regulations (that were announced last month) have been approved.

The FIA and ACO have worked closely with the upcoming LMH competitors, including Scuderia Cameron Glickenhaus, Toyota GAZOO Racing, and ByKolles (so far).

By tailoring the regulations to the needs of the entries, the FIA WEC can ensure a smooth beginning to the new era as it will take over as the top class of future endurance prototypes.

The release clarified the changes as the maximum power for the LMH was brought down from the initial 585kW (785 hp) to 500kW (670 hp).

There has also been a reduction in the minimum weight of the LMHs down from 1100kg to 1030kg.

This has been done to allow the cars to be run in a more cost-effective manner as the teams can ensure the smooth running and development of the cars, allowing them to achieve “performance objectives.”

“General principles of the convergence between the Le Mans Hypercar and Le Mans Daytona “h” have also been agreed.

“A unique Balance-of-Performance system (BoP) will ensure both types of cars will operate in the same performance window,” adjusting variables like power unit performance, aerodynamic characteristics and weight.

“LMDh will be based on one of the four chassis that will be available, and will be fitted with common rear hybrid system, a manufacturer-branded engine and a manufacturer-stylised bodywork.”

The Le Mans Hypercars are set to debut at the beginning of WEC’s Season 9 in March 2021.

Until then, the technical LMH regulations can be further tailored to the needs of the manufacturers as they venture deeper in their LMH projects.
