Corolla Attempts Groundbreaking 24-Hour Liquid Hydrogen Endurance Test
The world-first liquid hydrogen-powered Toyota GR Corolla H2 Concept made history by completing a 24-hour endurance race at Fuji International Speedway on May 28, 2023. The event, marked by technical challenges and operational hurdles, was a significant step forward in advancing hydrogen-powered motorsports.
The Challenges
Liquid hydrogen as a fuel presents unique challenges in storage, handling, and stable combustion due to its low temperature and volatility. Endurance races require sustained performance, reliability, and safety in harsh racing conditions such as fog and variable weather at Fuji Speedway. The team had to continuously develop and improve vehicle systems to manage fuel consumption and optimize powertrain efficiency during the race.
Key Developments
The 2023 race marked the car’s second 24-hour endurance participation, demonstrating Toyota's progress in building both the team and the car since the first event. The car completed 468 laps, a major improvement over the previous year's performance, reflecting advancements in vehicle endurance and fuel system reliability despite adverse conditions.
Technical improvements included enhanced liquid hydrogen fuel technologies and strategies refined through continuous data collection and feedback during the race to push the car’s endurance capabilities. Toyota's participation supports their broader zero-emission goals by using liquid hydrogen, advancing efforts toward carbon neutrality in motorsport and automotive technology.
No critical fuel-related issues were reported during this intense endurance race, signaling solid progress toward practical use of liquid hydrogen fuel in demanding motorsport environments.
The Corolla's Journey
The Corolla faced an unprecedented challenge and unrelenting trials during its development. The endeavor to run the Corolla on liquid hydrogen involved a great deal of trial and error. The team's challenges included maintaining the extreme temperature of -253°C and keeping the pump operational.
In a frantic effort to get back on track, the developers managed to shed 50 kg from the Corolla for the 24-hour race. The Corolla's successful run in the 24-hour race brought great delight to the mechanics, drivers, and all involved.
The number of laps completed by the Corolla (358) and the total distance covered (1,634 km) are significant, as they match the Corolla's previous feat at Fuji International Speedway, achieved two years earlier using gaseous hydrogen.
Partnership and Progress
New partners joined in the development process for the 24-hour race, contributing to the team's success. The developers' mantra for the endeavor was "The finish line is our starting line," reflecting their determination to overcome challenges and continue pushing the boundaries of hydrogen-powered motorsports.
