AI-summarised brief · reviewed before publication

At the Bonneville Salt Flats on August 11, a hydrogen‑powered JCB Hydromax vehicle set a new land speed record, reaching 400.623 mph on the first run and 412.135 mph on the second, averaging 406.320 mph. Wing Commander Andy Green, a former RAF fighter pilot, piloted the car, which is the fastest hydrogen internal‑combustion vehicle ever recorded. The achievement surpasses the previous hydrogen record of 303 mph and demonstrates the engine’s reliability and performance at extreme speeds.

💡 Why It Matters

  • · The record showcases hydrogen’s potential as a high‑performance, low‑emission power source, challenging the dominance of fossil fuels in speed‑critical applications.
  • · It signals a tangible step toward broader adoption of hydrogen technology in heavy‑industry sectors.
