Aston Martin F1 sponsor JCB has built its reputation on heavy lifting. Rather than digging, hauling or lifting, Hydromax went hunting for speed – powered by two production-based 4.8-litre hydrogen engines producing around 1,600 bhp combined. “To set a world record with hydrogen, 20 years after Dieselmax, is a privilege. The result more than doubled the previous hydrogen internal-combustion record of 185.5 mph and also eclipsed the 303 mph hydrogen fuel-cell mark, making Hydromax the fastest hydrogen-powered vehicle ever. As Lord Bamford put it: “It shows hydrogen works, and it works today at the highest level with zero emissions.”
