Driving a highly engineered specialty race car designed by construction equipment firm JCB called the Hydromax, the retired 64-year-old British fighter pilot made two attempts. In the first, he recorded an average speed of 400.623 miles per hour (mph), while on the second, he hit 412.135 mph, for an average top speed of 406.320 mph. Green is best known for holding the current land speed record, having hit 763.035 miles per hour driving a more conventional race in 1997. Tuesday's race shattered three Fédération Internationale de l’Automobile—the global governing body for motorsports—records: fastest hydrogen internal combustion engine (185.5 mph), fastest hydrogen fuel cell car (303 mph) and fastest electric vehicle (342 mph). The JCB Hydromax is among a class of race car designed to hit incredibly high speeds on straightaways known as gas blown streamliner.
