Hydrogen Officially Enters Le Mans Top Class: H2 Hypercar Debuts in 2030

H2 Hypercar: Hydrogen Becomes a Full Part of Le Mans' Highest Class

At the annual ACO press conference at Circuit de la Sarthe — held on the Friday before the 94th edition of the 24 Hours of Le Mans — the FIA, the Automobile Club de l'Ouest (ACO) and IMSA made a historic announcement: hydrogen will be officially integrated into the Hypercar class from 2030, the highest level of endurance racing.

It marks the first time in the history of endurance racing that the FIA and ACO have formally agreed on the use of hydrogen at the sport's top tier.

Two Technologies, One Class

Manufacturers wishing to compete with hydrogen may choose between two powertrain solutions: a fuel cell or a hydrogen internal combustion engine. Both are officially permitted and approved. H2 Hypercars will follow the new converged 2030 regulations — rear-wheel drive, hybrid — with several specific adaptations:

• Minimum weight of 1,200 kg (versus 1,040 kg for a conventional Hypercar)
• Dedicated tyres due to the additional weight
• Liquid hydrogen as the storage method — denser than gaseous hydrogen and selected by the FIA for the future category
• An Equivalence of Technology scheme to manage performance differences between hydrogen and conventional Hypercars, without granting a competitive advantage to either

Toyota Already Running on Liquid Hydrogen at Le Mans

One day before the press conference, on 11 June 2026, the Toyota TR LH2 Racing Prototype completed a demonstration lap on the legendary circuit powered by liquid hydrogen — a first for the Sarthe. Toyota has invested for years in both fuel cell and hydrogen combustion technology, and was the first manufacturer to respond enthusiastically to the ACO's plans.

Garage 56 as a Stepping Stone

ACO president Pierre Fillon did not rule out seeing hydrogen prototypes at Le Mans before 2030 through the Garage 56 class — the experimental entry slot reserved for cutting-edge technology. The regulations permit a hydrogen entry from 2028 onwards; the question is whether manufacturers will be ready by then.

A Single New Platform for 2030

The H2 Hypercar announcement forms part of a broader regulatory package. The FIA, ACO and IMSA also presented a new, converged technical platform for the entire Hypercar class from 2030 — a unified foundation for both the WEC and the IMSA WeatherTech SportsCar Championship. The current distinction between LMH (Le Mans Hypercar) and LMDh regulations will disappear as a result.

The Hypercar regulations have been extended until the end of 2032, providing manufacturers with unprecedented stability and long-term planning certainty. Ford and McLaren were also confirmed as new WEC entrants from 2027.

Hydrogen and Motorsport as a Laboratory

Le Mans has always served as a testbed for new technology — from diesel to hybrid powertrains. Integrating hydrogen into the top class is more than a sporting choice: it is a public demonstration that hydrogen is ready for the most demanding conditions, with high power outputs, rapid refuelling and extreme reliability requirements. That signal extends well beyond the circuit.
