Toyota has unveiled the GR LH2 Racing Concept, a liquid hydrogen prototype, at the Circuit de la Sarthe ahead of the 2025 Le Mans 24 Hours race. This hydrogen-powered race car is based on the GR010 Hybrid Hypercar and was developed by Toyota Gazoo Racing Europe in Germany. The powertrain engineering for the vehicle was conducted at Toyota's Higashi-Fuji Technical Centre in Japan. While specific technical details are yet to be disclosed, the GR LH2 Racing Concept represents Toyota's continued dedication to pushing the boundaries of hydrogen technology in endurance racing. Since 2021, Toyota has been actively involved in hydrogen racing through events like Japan's Super Taikyu series. The brand made a significant advancement in 2023 with the introduction of the GR Corolla H2, transitioning from gaseous to liquid hydrogen technology. The recent unveiling of the GR LH2 Racing Concept is a testament to Toyota's ongoing efforts in promoting sustainable racing practices. With the approval of liquid hydrogen safety regulations by the FIA World Motor Sport Council, which includes stringent guidelines for storage systems, vehicle integration, and refueling protocols, Toyota is now better positioned to pursue its hydrogen-powered Le Mans ambitions. These safety measures, such as pressure-tested compartments and hydrogen leak detection systems, ensure a regulated framework for manufacturers like Toyota to participate in hydrogen motorsport. The introduction of the GR LH2 Racing Concept signifies Toyota's leadership in hydrogen fuel innovation within endurance racing. While an official race debut is yet to be confirmed, the recent FIA approvals and Toyota's continuous research and development indicate a promising future for hydrogen-powered entries in events like Le Mans and the World Endurance Championship. This development marks a significant milestone in sustainable racing by utilizing liquid hydrogen combustion technology.
