Hydromax Breaks Bonneville Speed Bar With Hydrogen Power Ahead of FIA Bid

JCB’s Hydromax hydrogen-burning streamliner set a SCTA class record at Bonneville with a two-run average of 368.347 mph (367.141 mph first run, 369.554 mph second), fueled by twin 1,600 hp hydrogen internal-combustion engines. The result, a repeatable benchmark under SCTA rules, paves the way for an FIA-sanctioned world-record attempt while highlighting the heat and reliability challenges that must be managed under FIA restrictions.
