MissionH24 and TOYOTA RACING are stepping up their partnership. Following collaborations on cooling and aerodynamics, a new milestone has been reached with an agreement to supply a hydrogen combustion engine for MissionH24’s future prototype. The result will be enhanced performance for the H24EVO and zero CO2 emission.
September 26, 2026, at Fuji Speedway marks a new chapter in the history of MissionH24.
Launched in 2018 as a collaborative program between the Automobile Club de l’Ouest and H24Project to promote hydrogen in racing, the initiative is reaching a significant stage in its development. After the LMPH2G and the H24, which paved the way for zero CO2 emission racing using gaseous hydrogen and fuel cells, the H24EVO will soon undergo its first tests, equipped with a combustion engine and tanks storing liquid hydrogen.
The Automobile Club de l’Ouest, MissionH24, and Toyota Racing shared this announcement with the public and the media during the FIA World Endurance Championship round currently taking place at Fuji Speedway.
The TOYOTA RACING engine, is based on a 3.5-liter V6 developed specifically for motorsport. When paired with the prototype’s hybrid system, it is expected to deliver a maximum power output of 650 kW, significantly boosting the H24EVO’s performance and bringing it closer to the level of a prototype in ELMS (European Le Mans Series) ; a step up from the LMGT3 performance level targeted by its predecessors.
Pierre Fillon, President of the Automobile Club de l’Ouest and Co-President of MissionH24:
“This new collaboration between MissionH24 and TOYOTA RACING reflects our respective commitments, shared by all MissionH24’s partners, to successfully achieve the energy transition. Hydrogen is one of the solutions for decarbonizing mobility. This pioneering program involves various phases. We stated this from the very beginning, hence the name ‘MissionH24’, because while we know our goal, we do not necessarily know every step we will need to take to get there. Gaseous and liquid hydrogen, fuel cells, and engines all offer opportunities for hydrogen storage and utilization. TOYOTA’s support demonstrates MissionH24’s determination and ambition.”
Kazuki Nakajima, Vice Chairman of TOYOTA RACING GmbH:
“We are excited about this next step of our cooperation between MissionH24 and TOYOTA RACING, and I would like to thank MissionH24 for their trust and expectation for TOYOTA RACING’s hydrogen combustion engine. This is an important milestone for TOYOTA RACING since our mission is the continuous pursuit of the possibilities for combustion engine development, including hydrogen technology, and to deliver its potential to a wider range of stakeholders. I would also like to thank our colleagues in Japan for their effort and commitment to drive the hydrogen combustion engine development and its supply for MissionH24. This is a great step for the future after the demonstration of TR LH2 Racing Prototype back in Le Mans in June, and I’m grateful to see expansion of hydrogen technology possibilities.”
Jean-Michel Bouresche, CEO of H24Project and Co-President of MissionH24:
“I am delighted that, via TOYOTA RACING, the world’s leading car manufacturer and a long-standing pioneer in hydrogen technology, is stepping up its commitment to MissionH24 by supplying its hydrogen combustion engine for the H24EVO. This sends a powerful signal to all stakeholders in the hydrogen sector and to all MissionH24 partners. Using the TOYOTA RACING’s engine will allow us to reach a major milestone, both in terms of credibility and performance. It is a source of great satisfaction and immense motivation for all our partners and the entire MissionH24 team.”
Bassel Aslan, Technical Director of MissionH24:
“This support from TOYOTA RACING is a tremendous boost for the H24EVO and MissionH24. It is already taking concrete form, as MissionH24 and TOYOTA RACING teams are currently working together on the engineering required to integrate the engine into the H24EVO. This work includes, in particular: designing the mechanical interfaces between the engine, chassis, and gearbox ; and defining the communication architecture, electrical interfaces, controls, and associated software requirements. This engine also offers high efficiency, a key asset for optimizing the use of onboard liquid hydrogen and, consequently, the vehicle’s range, which is a major advantage in endurance racing.”
