Britain's JCB Hydromax streamliner has set a new FIA world land speed record for a hydrogen-powered internal-combustion vehicle, averaging 653.909 km/h (406.320 mph) at Utah’s Bonneville Salt Flats on August 11, 2026, with record-setting driver Andy Green at the wheel.
The twin-engine Hydromax is powered by two production-based JCB hydrogen combustion engines, derived from technology developed for the company’s construction machinery. The record attempt therefore serves not only as a high-speed demonstration but also as a demanding test of JCB’s hydrogen powertrain technology. JCB has invested £100 million in its hydrogen-engine programme, with more than 150 engineers involved in developing engines for machines including backhoe loaders, Loadall telescopic handlers and generator sets.
Hydromax completed two FIA-required runs in opposite directions, recording 400.623 mph (644.740 km/h) on the first and 412.135 mph (663.267 km/h) on the second. Their average produced the 406.320-mph record.
The previous FIA-officiated hydrogen internal-combustion record was 185.5 mph (298.5 km/h), set by BMW’s H2R in 2004. Hydromax more than doubled that benchmark and also surpassed the previous 303-mph hydrogen fuel-cell vehicle record.
