The JCB Hydromax set a speed record among hydrogen-powered cars
The JCB Hydromax set a new speed record for hydrogen-powered vehicles, achieving an average speed of 406.320 miles per hour on the Bonneville Salt Flats in the United States. According to InsideEVs, this is the highest result among all vehicles that use hydrogen as an energy source.
The record was determined based on the results of two runs conducted over the course of an hour. During the first run, the car reached 400.623 miles per hour, and during the second, 412.135 miles per hour. The previous record for a vehicle with a hydrogen internal combustion engine was held by the BMW H2R: in 2004, it reached 185.5 miles per hour. The fastest hydrogen fuel cell car prior to this had reached 303 miles per hour.
The JCB Hydromax is equipped with two 4.8-liter turbocharged inline four-cylinder internal combustion engines that run on hydrogen. Each engine produces 800 horsepower, and the total power output of the powertrain is 1,600 horsepower. One engine drives the front axle via a six-speed Xtrac transmission, while the other drives the rear axle.

According to the publication, during the record-breaking run, the car consumed two kilograms of hydrogen and emitted 18 liters of water. Hydrogen contains no carbon, so no CO2 was produced during the runs, although the emissions also contained a certain amount of nitrous oxide. At the wheel of the JCB Hydromax was Air Commodore Andy Green, who also holds the absolute land speed record of 763.035 miles per hour.
FIA President Mohammed Ben Sulayem stated that this new achievement demonstrates the potential of hydrogen combustion for sustainable mobility. The article also notes that Toyota is competing in races with the hydrogen-powered Toyota GR Corolla H2 and has developed the GR LH2 Racing Concept for Le Mans.
