Toyota joins final 2025 Super Taikyu race to push hydrogen engine technology

After highlighting its multi-pathway approach in achieving carbon neutrality at the 2025 Japan Mobility Show, Toyota is showing no signs of slowing down.

In fact, Toyota recently joined Round 7 of the 2025 ENEOS Super Taikyu Final Thanksgiving Festival last November 15 – 16, 2025. There, Toyota competed with the TGRR GR Corolla H2 Concept, which runs on liquid hydrogen fuel.

This is not the first time Toyota has joined a race with a GR Corolla that runs on liquid hydrogen. Back in December 2022, Toyota joined the Idemitsu 1500 Super Endurance Race at the Chang International Circuit in Buriram, Thailand, with a GR Corolla H2 Concept and a GR86 that ran on carbon-neutral fuel.

Back to the Super Taikyu race, the liquid hydrogen-powered GR Corolla that competed last weekend achieved significant progress. Not only did the hot hatch show it can perform while using liquid hydrogen, but the car was able to finish the race with ease. However, Toyota did say that the increased engine output placed a greater load on the fuel pump, presenting durability challenges when the car was running at maximum output during the 24 Hours of Fuji earlier this year.

Toyota is hoping that with continuous endurance race tests, it will be able to achieve continuous operation of the pump even at maximum output.

The automaker is also working on superconductivity technology to expand the potential of liquid hydrogen technology by installing a superconducting pump inside a fuel tank. By using a compact superconducting fuel pump, Toyota says it creates more volume, which translates to more than a 1.3-fold increase in tank capacity, thus increasing cruising range. There's also the matter of keeping hydrogen in liquid form, which can be done by keeping the temperature at -253 degrees Celsius, which can be troublesome when used in production cars.

For now, the use of liquid hydrogen as a fuel source remains exclusive to racing. But with Toyota's commitment to a multi-pathway approach in achieving carbon neutrality, the automaker plans to greatly expand the potential of hydrogen engine vehicles.
