This third-generation hydrogen prototype, unveiled at Le Mans in June, will feature significant technological advances. The new liquid hydrogen storage system will operate at -253 degrees Celsius in thermally insulated tanks, carrying between 11-14kg of hydrogen. This upgrade extends the driving range to at least 40 minutes, a 10+ minute improvement over the previous system.
Key specifications include:
- 300kW Symbio fuel cell
- 650 KW (872 hp) electric motor
- Target weight: 1300 kg
- Projected top speed: 211.3 mph
- Performance target: GT3 pace level
The development timeline includes:
- May 2025: Design freeze
- June 2025: Second appearance at Le Mans Hydrogen Village
- October 2025: Bench testing
- February 2026: Full assembly of ADESS-based prototype
- April 2026: Track testing
ACO President Pierre Fillon emphasized at the Hyvolution Paris exhibition that this transition represents a crucial phase in achieving zero CO2 emissions in motor racing, combining liquid hydrogen competition with the challenge of matching conventional combustion engine performance.
The Automobile Club de l'Ouest (ACO) continues to develop regulations with manufacturers for hydrogen-powered prototypes to compete at Le Mans and in the FIA WEC by the decade's end, though specific regulatory timelines remain undisclosed.
