Here is the thing about the relentless march of motorsport engineering: sometimes, collaborations that start in the shadows of cooling and aerodynamics suddenly leap forward into something massive. MissionH24 and TOYOTA RACING have officially leveled up their partnership, reaching an agreement that will see the automotive giant supply a hydrogen combustion engine for MissionH24's future prototype, the H24EVO, with a target of zero CO2 emissions.
The Automobile Club de l'Ouest (ACO), MissionH24, and TOYOTA RACING dropped the news jointly at Fuji Speedway in Japan during the sixth round of the 2026 FIA World Endurance Championship campaign. It marks a bold new chapter for an initiative first launched back in 2018 by the ACO and H24Project to champion hydrogen in motorsport.
This support from TOYOTA RACING is a tremendous boost for the H24EVO and MissionH24,
"This new collaboration between MissionH24 and TOYOTA RACING reflects our respective commitments, shared by all of MissionH24's partners, to successfully achieve the energy transition," said Pierre Fillon, President of the ACO and Co-President of MissionH24, noting that hydrogen remains a key solution for decarbonising mobility. "Gaseous and liquid hydrogen, fuel cells and engines all offer opportunities for hydrogen storage and utilisation – and Toyota's support demonstrates MissionH24's determination and ambition."
Under the hood, the beast is taking shape. The TOYOTA RACING power unit is a motorsport-specific 3.5-litre, V6 engine. When combined with the prototype's hybrid system, it is projected to pump out a maximum power output of 650 kW. That is a serious jump in performance, pushing the H24EVO much closer to the capability of a prototype in the European Le Mans Series, a distinct step up from the LMGT3 performance level targeted by its predecessors, the LMPH2G and the H24.
“This support from TOYOTA RACING is a tremendous boost for the H24EVO and MissionH24,” explained Bassel Aslan, Technical Director of MissionH24. The engineering teams are already deep in the trenches together, designing mechanical interfaces between the engine, chassis, and gearbox, alongside mapping out the electrical interfaces, controls, and software requirements.
Kazuki Nakajima, Vice Chairman of TOYOTA RACING GmbH, emphasized that the move follows the demonstration of the TR LH2 Racing Prototype at Le Mans in June. Meanwhile, Jean-Michel Bouresche, CEO of H24Project and Co-President of MissionH24, hailed the deal as a powerful signal of credibility and performance for the entire sector as the H24EVO prepares to undergo its first tests running on liquid hydrogen.
