British driver Andy Green set a new hydrogen-powered land-speed record of 406.320 mph on Tuesday [1].
The achievement serves as a high-profile test of hydrogen-combustion technology, suggesting that zero-carbon fuels can sustain extreme performance levels previously reserved for fossil fuels [2, 4].
Green reached the record speed of 406.320 mph, or 653.908 km/h, while driving the JCB Hydromax [1]. The run took place on Aug. 11 at the Bonneville Salt Flats in Utah [1, 2].
Green is already known in the racing world as a former supersonic land-speed record holder [1, 4]. This latest attempt focused on the potential of hydrogen as a viable power source for high-speed vehicles [2, 4].
The JCB Hydromax is designed to showcase how hydrogen-combustion engines can operate under extreme stress, a key requirement for industrial applications and high-performance transport [2]. By utilizing the flat, expansive terrain of the Utah salt flats, the team was able to push the vehicle to its absolute limit [2, 3].
While some reports rounded the figure to 406 mph, official data confirms the precise speed of 406.320 mph [1, 3]. The event marks a significant milestone for the JCB project and the broader effort to transition away from traditional internal combustion engines without sacrificing power [2, 4].

This record demonstrates that hydrogen combustion can match the raw power and speed of traditional fuels. While land-speed records are specialized events, the successful application of this technology at 406 mph provides a proof-of-concept for hydrogen in heavy-duty transport and high-performance engineering, potentially accelerating the shift toward carbon-neutral combustion engines.
