Toyota unveiled its innovative GR LH2 Racing Concept, a hydrogen-powered prototype, at the Circuit de la Sarthe on June 10, 2025, just days before the 24 Hours of Le Mans. This event marks a significant step in Toyota’s commitment to hydrogen combustion engine technology in motorsport, signalling a future for sustainable racing, as reported by Autosport.
The GR LH2 Racing Concept uses the chassis from Toyota’s GR010 Hybrid Hypercar, which competes in the World Endurance Championship (WEC). Toyota’s Higashi-Fuji Technical Centre in Japan developed the hydrogen system and powertrain to enhance the capabilities of hydrogen combustion engines. Toyota Gazoo Racing’s facility in Cologne, Germany, constructed the chassis.
Kazuki Nakajima, vice chairman of Toyota’s WEC team and a three-time Le Mans winner, emphasised the project’s goals: “We aim to expand the possibilities of hydrogen combustion engine technology and learn about infrastructure and fueling systems.” While the company has not disclosed technical details, the prototype demonstrates Toyota’s commitment to green racing innovation.

Toyota’s hydrogen racing focus supports its broader sustainability efforts. The company has tested hydrogen technology in motorsport, with the GR LH2 marking a key milestone. Although Toyota delayed plans to introduce hydrogen-powered cars to WEC by 2024, the FIA’s recent approval of liquid hydrogen storage rules sets a 2028 integration target, according to the FIA.
Nakajima hinted that the GR LH2’s racing debut is imminent, though he did not confirm an exact timeline. The prototype’s development could pave the way for hydrogen-powered vehicles in global racing circuits.
The GR LH2 Racing Concept positions Toyota as a leader in sustainable motorsport. Hydrogen combustion engines offer a low-carbon alternative to traditional fuels, reducing emissions while maintaining high performance. The technology’s success in racing could accelerate its adoption in consumer vehicles, supporting global decarbonization goals.
Fans on X expressed excitement, with many praising Toyota’s innovation as a game-changer for Le Mans and beyond. The unveiling has sparked discussions about hydrogen’s role in motorsport’s future.
