This JCB doesn't dig – it does 406 mph

On Tuesday, a JCB set a world land speed record by reaching 406 mph (653 kph) at Utah's Bonneville Salt Flats. The vehicle, called the JCB Hydromax, is not a typical digger or dumper, but a hydrogen-powered car driven by Wing Commander Andy Green, a former Royal Air Force fighter pilot. The JCB Hydromax averaged 406.320 mph (653.909 kph) during two runs, making it the fastest hydrogen-powered internal combustion car ever recorded.

The car is powered by two engines made at JCB's factory in Derbyshire, which deliver a combined 1,600 bhp. JCB has invested £100 million in hydrogen engine technology, believing hydrogen is more suitable for heavy equipment due to its long operating hours and rapid refueling capabilities. Burning hydrogen produces no carbon dioxide at the tailpipe, although combustion engines can still emit nitrogen oxides.

JCB states that the two engines in the Hydromax were extensively modified to meet the demands of the speed record attempt, including the use of spark plugs designed for a Le Mans 24 Hour engine. The car's steel-frame chassis is similar to a conventional racing car, and the driver sits in a composite monocoque sub-chassis under a drag racing-style steel roll cage.

JCB's chairman, Tony Bamford, led the hydrogen engine project and aimed for the world land speed record, emphasizing that hydrogen works at the highest level with zero emissions. The FIA officially confirmed the record.
