The details of the LMDh regulations have been released as part of the convergence between IMSA and WEC in the long-term future for sportscar endurance motorsport.

An extended LMDh press conference and presentation was planned at the SuperSebring race weekend, where IMSA’s 12 Hours of Sebring and WEC’s 1000 Miles of Sebring would come together. This was until the events were postponed following the COVID-19 pandemic circumstances.

The initial details were first released last week, in the intention to interest automotive manufacturers and chassis constructors. The four main chassis constructors include Dallara, Ligier, Multimatic and Oreca.

The cars themselves are set to feature:

  • A manufacturer branded and stylized bodywork
  • A manufacturer-branded engine
  • A common single source rear-wheel-drive hybrid system
  • A minimum homologation period of five years

Based on the LMDh joint regulations, the new LMDh will comprise of:

  • Minimum car weight at 1030 kg
  • 500 kW peak of combined power (sum of power resulting from internal combustion engine [ICE] and hybrid system)
  • One bodywork package with identical aerodynamic performance
  • Single tire supplier (i.e. Michelin)
  • Global BOP (Balance-of-Performance) to establish the overall performance of the LMDh and LMH cars

“Officially launched in Daytona in January, the ACO-IMSA convergence is now entering an important phase in its implementation,” Pierre Fillon, President of ACO, said.

“We are unveiling the basic technical details of this new LMDh category which will see the same car being allowed to race in the FIA World Endurance Championship and the IMSA WeatherTech SportsCar Championship, without any modification necessary to the car. The dream of many manufacturers is finally coming true.

“Le Mans Daytona H. and Le Mans Hypercar will embody the top category of endurance racing. This is a historic and decisive moment for the future of our discipline. ”

Ed Bennett, CEO of IMSA said: “We have reached another key milestone with the release of our draft technical regulations for LMDh.”

“There is still more work to be done, but the positive spirit of collaboration between the ACO and IMSA, as well as our four constructors and many interested manufacturers, has been fantastic and truly unprecedented.

“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 sports car racing around the globe.”

The CEO of the FIA World Endurance Championship, Gérard Neveu also commented: “Since the coronavirus pandemic, the way in which motorsport will be thought about in the future has undoubtedly been affected.”

“Our strategy for LMDh is to try to find the best answer to manufacturers’ technical and competitive wishes, as well as offering them the greatest global visibility for their brands.

“The top category of competition will now include low cost, high performing cars which respond to the needs of both our respective championships.”
