Toyota Motor Corporation announced it will advance hydrogen engine technology at the ENEOS Super Taikyu Series 2025 Empowered by BRIDGESTONE Round 7, taking place from November 15 to 16. The company will enter the #32 TGRR GR Corolla H2 concept, a vehicle powered by liquid hydrogen fuel.
Toyota has also reached a new stage in developing superconductivity technology for use with liquid hydrogen engines. Vehicles equipped with superconducting motors for liquid hydrogen pumps are now operational, and Toyota plans to continue this development with its partners for future races.
According to Toyota, these efforts are part of its multi-pathway strategy aimed at achieving carbon neutrality. The company stated: “Achieving zero, and adding new value beyond it.” Toyota added that it is working to address societal issues and reduce negative impacts on people and the environment, while seeking ways to improve lives and society for the future.
The GR Corolla H2 concept previously achieved progress during the ENEOS Super Taikyu Series Round 3 NAPAC Fuji 24 Hours Race earlier this year. Improvements included enhanced safety, weight reduction through a new filling valve, and successful demonstration of combustion switching technology. The vehicle completed the race without needing a pump replacement, confirming improved durability. However, increased engine output continues to challenge pump durability under continuous maximum load. Toyota will conduct further tests during this event to verify boost performance and durability.
The integration of superconductivity technology allows vehicles to run with a superconducting pump inside the fuel tank. This design could increase tank capacity by more than 1.3 times and improve cruising range due to space savings from compact motor installation. Other expected benefits include reduced vehicle weight, lower center of gravity, and decreased boil-off volume as heat input sources are minimized.
The -253°C temperature required for liquid hydrogen is suitable for superconductivity applications because certain materials lose all electrical resistance at extremely low temperatures.
In addition to racing activities, Toyota will participate in an automotive cultural exchange event organized by the Automobile Business & Culture Association of Japan during the race weekend. U.S.-produced vehicles such as the Camry sedan, Highlander SUV, and Tundra pickup truck will be displayed at the event plaza on November 15-16. Visitors can see and ride in these models not typically available in Japan.
Toyota’s broader goals include developing innovative products that support mobility for all while contributing toward sustainability objectives outlined in its Beyond Zero initiative and SDGs Initiatives.
