Breaking new ground at lightning speed, JCB‘s Hydromax has shattered records at the legendary Bonneville Salt Flats in Utah. This formidable machine, designed with dual 800 horsepower hydrogen-powered engines, reached a remarkable 406.320 mph (653.6 km/h). It now stands as the fastest hydrogen-powered vehicle ever, achieving the top honor for hydrogen internal-combustion cars.
The 32-foot streamliner isn’t just about speed; it innovates by burning hydrogen directly in its combustion engines. These engines are crafted at JCB’s facility in Foston, Derbyshire, the same ones powering their renowned construction machinery in the UK.
Hydrogen Speed Milestones
The record success was orchestrated by the skilled hands of Wing Commander Andy Green OBE. Despite the challenge of maintaining precision, Green managed speeds of 400.623 mph and 412.135 mph during a meticulously executed run, delivering the official average. This performance obliterated the previous hydrogen combustion benchmark of 185.5 mph set by BMW’s H2R in 2004, further solidifying the championship claim.
Ryan Ballard, JCB Engineering Director, highlighted the dedication involved, saying, “This record is a testament to the engineering prowess that transformed a hydrogen digger engine into the world’s fastest of its kind. From its conception last February, the project faced immense challenges yet emerged triumphantly prepared.”
The path to this achievement was paved with previous successes. At the 2026 Bonneville Speed Week, Hydromax set an SCTA record averaging 368.347 mph. Each trial contributed valuable insights, especially crucial before its FIA-sanctioned attempt, ultimately leading to the remarkable accomplishment.
Hydromax is a feat of engineering aimed at balancing extreme speed and control. Equipped with a four-wheel drive and advanced aerodynamic design, its components like suspension and traction control were rigorously tested. Collaborations with Prodrive, Ricardo, and Xtrac ensured peak performance in build, engine tuning, and transmission, all contributing to the ultimate goal.
JCB’s journey is one of legacy and innovation. Exactly two decades after Andy Green set the diesel record in the JCB Dieselmax at the same location, he returns to set an even higher bar with hydrogen. The Hydromax story, originating in 2025, showcases JCB’s commitment to advancing hydrogen combustion technology, crowned by their definitive achievement.
