British driver Andy Green, the only person to break the sound barrier in a car, returns to Utah’s Bonneville Salt Flats to attempt another land speed record. Twenty years after his earlier run, which set a record of 350.092 mph (563.4 km/h) in a diesel-powered car, Green plans to target a faster result this time using a hydrogen-powered vehicle. He is scheduled to make another attempt on Tuesday at the salt flats.

Outlets describe the effort as a bid to surpass Green’s own long-standing benchmark while also highlighting the hydrogen aspect of the technology. One report frames the attempt primarily as a second shot at the land speed record, emphasizing that his previous success came two decades earlier. Another report, drawing on an AP dispatch, underscores that Green sets or earns a world record during the hydrogen run, presenting it as evidence of hydrogen power in a high-speed setting. The core details across sources are Green’s identity, the Utah location, and his transition from diesel to hydrogen for the attempt.
