JCB hits 368mph at Bonneville: hydrogen ICE performance insights for engineers
Reviewed by Joe Ashwell

First reported on The Construction Index
30 Second Briefing
JCB’s Hydromax hydrogen-powered streamliner has reached 368.347mph at the Bonneville Salt Flats, breaking the Southern California Timing Association Blown Gas Streamliner (AA/BGS, 500+ cubic inches) class record of 348.342mph set by the Spectre Streamliner in 2010. Driven by Wing Commander Andy Green OBE, the car uses two production-based JCB hydrogen internal combustion engines now being pushed towards a combined 1,600hp. The team is preparing the vehicle for an FIA-sanctioned outright world land speed record attempt next week, positioning hydrogen ICE as a zero-emission, high-load power option for heavy plant.
Technical Brief
- Hydromax runs two production-based JCB hydrogen ICE units, not bespoke race-only prototypes.
- Powertrain tuning is being progressively increased towards the engines’ full combined 1,600 hp capability.
- Record was certified under Southern California Timing Association AA/BGS (500+ cubic inches, blown gas) rules.
- New class mark exceeds the prior SCTA AA/BGS record by 20.005 mph.
- AA/BGS class record had stood unbroken since 2010, with no improvement for 16 years.
Our Take
JCB’s use of the Hydromax hydrogen engine at Bonneville gives it a high‑profile demonstrator that complements its more conventional fleet upgrades seen in our database, such as the LiveLink telematics enhancements for Hi‑Viz Loadalls, signalling that alternative fuels are being explored alongside digital efficiency gains rather than instead of them.
For quarrying and concrete operators already buying JCB equipment – like Base Concrete’s recent TM420 purchase – a 368mph hydrogen record run by a UK manufacturer helps de‑risk perceptions around hydrogen combustion technology, making it easier to justify trialling low‑carbon powertrains on loaders and telehandlers in future procurement cycles.
