Toyota Gazoo Racing unveils liquid hydrogen-powered GR LH2 concept at Le Mans
On 11 June 2025 in Le Mans, France, Toyota Gazoo Racing (TGR) unveiled its GR LH2 Racing Concept, a liquid hydrogen-fuelled test car, at the H2 Village during the 24 Hours of Le Mans. This experiment aims to bring hydrogen combustion technology closer to being viable in motorsport - and potentially in a future Le Mans hydrogen class.
Why hydrogen? Why now?
Toyota's carbon-neutral goal: The company sees hydrogen combustion as a zero-emission alternative to fossil fuels, complementing its efforts in battery-electric and hybrid technology.
Racing R&D: Since 2021, TGR has been testing hydrogen engines in Japan’s Super Taikyu Series, first with gaseous hydrogen and then with liquid.
Le Mans Legacy: Last year's GR H2 Concept hinted at a hydrogen category, and this LH2 version represents a significant technical advancement.
Based on the Toyota Le Mans Hypercar (GR010 Hybrid), the GR LH2 features a Liquid Hydrogen V6 engine (specific details are undisclosed, but it is likely to be derived from the Corolla H2 racer) and a hybrid system that retains electric boost for acceleration. With a length of 5.1 m and a width of 2.05 m, it is identical in size to the GR010 to ensure regulatory parity.
The big question: Will hydrogen ever race at Le Mans?
Although there is no official hydrogen class yet, Toyota’s investments and the ACO’s H2 Village showcase signal growing momentum. If liquid hydrogen proves to be a viable option for endurance racing, it could transform the world of sustainable motorsport.
