Driver who broke the sound barrier attempts another land speed record in Utah

WENDOVER, Utah (AP) — The first — and only — person to break the sound barrier in a car hits the track in Utah this week with new wheels and his eye on another record.

Twenty years ago, British driver Andy Green set the land speed record for a diesel-powered car, reaching 350.092 mph (563.4 kph) at Utah’s famous Bonneville Salt Flats. Green will return to the lunarlike landscape Tuesday and try to beat that mark, this time with a hydrogen-powered car.

The retired Royal Air Force fighter pilot aims not only to win another accolade but to showcase the power of hydrogen as a clean-energy alternative. It’s the “fuel of the future,” Green told The Associated Press in a July interview.

Green will be driving the 32-foot (9.75-meter) JCB Hydromax, the brainchild of British construction equipment manufacturer JCB. The car is bright yellow, long and slim, resembling a pencil. It’s powered by two hydrogen internal combustion engines with a combined 1,600 horsepower, which were adapted from engines used in the company’s construction machinery. They mix pressurized hydrogen gas with air and ignite it to create bursts of power.

In targeting the diesel-powered record, Green also hopes to easily clear the world land speed records for hydrogen internal co...
