Toyota’s Hydrogen GR Corolla Debuts a Superconducting Liquid Hydrogen Pump at the Fuji 24 Hours

Toyota has taken its hydrogen-engine GR Corolla back to long-distance racing and added a piece of technology that sounds more at home in research labs than on a track. Ahead of Round 3 of the Super Taikyu Fuji 24 Hours, Toyota Global Newsroom said its hydrogen-powered GR Corolla once again joined the event in 2026, and this year it ran with an onboard superconducting liquid hydrogen pump described as the first of its kind in the world for a race car.

The program is now in its sixth year, and Toyota’s head of the project, Akio Toyoda, also known as “Morizo,” sent a message to the team before the race. Toyota framed the effort as continuing a longer journey toward future vehicle technologies, but the competitive setting is also central. Racing exposes powertrains and fuel systems to vibration, thermal swings, and repeated high loads, conditions that make advanced components harder to deploy reliably.

Toyota said the core change involves how liquid hydrogen is pumped. Liquid hydrogen sits at extremely low temperatures, around minus 253 degrees Celsius. Toyota’s approach, according to the release, is to exploit those low temperatures to replace the conventional electric motor used to pump the fuel with a smaller, higher-performance superconducting motor.

The release also describes a packaging strategy tied to the new motor. Instead of placing the motor above the tank, Toyota’s design locates it inside the tank. Toyota said that this increases the effective tank capacity, and it cited a doubling of the liquid hydrogen volume compared with the car’s first tank configuration. Toyota linked that volume increase to a longer-term goal: enabling a driving range comparable to gasoline-powered vehicles.

While the promise is bigger range through better use of space and improved pumping performance, Toyota emphasized that superconductors, which conduct electricity without resistance, are usually used in stable, low-vibration environments. That constraint matters in racing, where the whole vehicle experiences constant mechanical shocks and oscillations.

Toyota quoted Kyoto University professor Taketsune Nakamura, who supported development, saying that using a superconducting motor in a race car is “almost unthinkable,” underscoring how unusual and difficult it is to adapt superconducting technology to the vibration-heavy realities of endurance motorsport. The company’s framing was that engineers, mechanics, drivers, and others had to work through multiple challenges step by step to make the system work in the first place.

The release did not provide qualifying performance, lap times, or reliability metrics for this specific round, and it did not confirm what the team expected to learn from the debut beyond the broader technical objective. It also did not specify the operating limits of the pump or superconducting motor, such as endurance duration at full load or how the team handled start-up and thermal conditioning in race conditions.

Still, the story fits into Toyota’s wider use of motorsport as a testbed for propulsion and energy technologies. Endurance races can function as a forcing mechanism, because fuel delivery must remain consistent over hours, and any instability in pumping, thermal behavior, or component durability can translate into missed pit stops, reduced power, or retirement. By pairing liquid hydrogen’s cryogenic properties with superconducting components, Toyota is essentially trying to turn a fundamental challenge of hydrogen storage into an engineering advantage for the fuel system.

What to watch next is whether the superconducting liquid hydrogen pump delivers not only technical feasibility but also repeatable performance over the event’s distance. Toyota’s immediate question is whether the hydrogen-powered GR Corolla makes it to the checkered flag, and the broader question is whether a design that increases liquid hydrogen volume and integrates the motor into the tank can be proven under endurance stresses well enough to move from “world-first” hardware to a more scalable path for future vehicles.
