On the occasion of the 2020 Rolex 24 At Daytona, the two sanctioning bodies unveiled the guiding principle for this platform – the introduction as the top category of competition of LMDh, which will be eligible for both the FIA World Endurance Championship (WEC) and the IMSA WeatherTech SportsCar Championship. This joint platform responds to the wishes of numerous manufacturers.
The ACO and IMSA have together established the basis for joint regulations to govern the new LMDh category. The objective is that, from September 2021 in the FIA WEC and from January 2022 in the WeatherTech Championship, manufacturers will be able to enter the top category and compete in the two leading championships in endurance racing with this new model of car, LMDh.
The two sanctioning bodies were inspired by elements from each of their respective regulations, namely from the ACO’s Le Mans Hypercar and those in preparation by IMSA for the DPi 2.0.
The result of this convergence, the LMDh car will be:
• Based on a new chassis common to both ACO and IMSA, using elements of the Le Mans Hypercar and LMP2 chassis, and built by the four current LMP2 manufacturers: Dallara, Ligier, Multimatic and Oreca. This chassis will also be used for the new generation LMP2.
• The car will use a common hybrid KERS system, on the rear axle.
• Its silhouette and design will be modifiable, developed according to the brand or style of the manufacturer which will provide the engine power for the car
More technical details for the car will be revealed in March at SuperSebring, in a presentation from the ACO and IMSA Technical Departments.
In the future the top category of endurance racing will include both LMDh and Le Mans Hypercar. A balance of performance system will ensure fair competition.
