Toyota has revealed its latest innovation in motorsports with the introduction of the GR LH2 Racing Concept, a hydrogen-powered hypercar designed to push the boundaries of hydrogen technology on the race track. Unveiled at the Circuit de la Sarthe just days before the prestigious 24 Hours of Le Mans race, the GR LH2 features a hydrogen engine combined with a hybrid system. The concept serves as a tribute to Toyota's 40th anniversary of participating in Le Mans and is based on the GR010 Hybrid Hypercar used in the World Endurance Championship. While specific details on the powertrain and hydrogen system were limited, the GR LH2 was constructed at Toyota's Higashi-Fuji Technical Centre in Japan, with the chassis produced at the Gazoo Racing facility in Cologne, Germany. The GR LH2's design includes new bodywork, revised side intakes, a larger rear wing, and a distinctive white-and-blue livery. Toyota's commitment to hydrogen innovation is further highlighted by the operational nature of the GR LH2 as a running test car, in contrast to the static GR H2 concept. Toyota has been a pioneer in hydrogen engine technology in motorsports since 2021, with ventures like the Super Taikyu racing series in Japan and rally racing with the GR Yaris H2. The GR LH2's development signifies Toyota's continued efforts to promote hydrogen as a sustainable energy source while maintaining performance and enhancing its motorsport presence. By unveiling the GR LH2 ahead of the 24 Hours of Le Mans, Toyota showcases its dedication to advancing hydrogen technology in the automotive industry. The running test car status of the GR LH2 hints at significant progress in Toyota's hydrogen initiatives, underscoring the company's long-term commitment to sustainable innovation in motorsports.
