Toyota is set to race a proposed hydrogen combustion Hypercar in the 2028 World Endurance Championship, running alongside their current GR010 HYBRID. The car will be developed from the 2023 GR HY Concept and is expected to participate in multiple races in its debut season, including the Le Mans 24 Hours. The ACO and FIA are collaborating to introduce regulations allowing hydrogen cars to compete equally by 2028. Toyota is prioritizing their hydrogen project over building a conventional car to meet the 2030 rules due to development constraints. The governing bodies acknowledge the challenges of integrating hydrogen technology into the WEC's premier class, highlighting the need for extensive planning and coordination among stakeholders for a successful transition.
