British prototype equipped with two hydrogen internal combustion engines averaged 406.320 mph at Bonneville; result still awaits official FIA ratification
British manufacturer JCB has taken hydrogen combustion technology to a new level of performance. The JCB Hydromax prototype achieved an average speed of 406.320 mph, equivalent to approximately 653.9 km/h, during a record attempt on the Bonneville Salt Flats in the United States.
The result was obtained from two runs in opposite directions, as required by Fédération Internationale de l’Automobile (FIA) regulations. On the first run, the Hydromax recorded 400.623 mph (644.7 km/h). On the second, it reached 412.135 mph (663.3 km/h).
The average of the two runs placed the car well above the previous benchmark for vehicles equipped with hydrogen-powered internal combustion engines. The BMW H2R had recorded 185.5 mph, around 298.5 km/h, in 2004.
Despite the result, the new record is still subject to official FIA ratification. The attempt was made in Category A, Group XIV, Class 7 of the World Flying Start Land Speed Records.
