JCB, which sponsors Aston Martin in F1, will return to the Bonneville Salt Flats in Utah after two decades.
The FIA will oversee a hydrogen-fueled land speed record attempt by British manufacturer JCB at the Bonneville Salt Flats in Utah, marking their return to record-breaking after 20 years with a new benchmark using hydrogen internal combustion engine technology.
Wing Commander Andy Green OBE, the only person to break the sound barrier on land, will pilot JCB’s purpose-built Hydromax vehicle, aiming to surpass the FIA world diesel land speed record of 350.092mph set by JCB’s Dieselmax in 2006.
FIA President Mohammed Ben Sulayem described the endeavor as a historic moment for speed, technology, and innovation, pushing boundaries of aerodynamics, engineering excellence, and human bravery, symbolizing a collaboration of ambition and innovation.
The 32-foot Hydromax vehicle will feature two JCB hydrogen combustion engines producing 1,600bhp, part of the company’s broader hydrogen program developed through a significant investment.
Preceding testing in the UK, the team will participate in Bonneville SpeedWeek to target officially recognized world records under FIA regulations, showcasing the ongoing progress in engineering and innovation through record attempts.
