JCB attempt a new world land speed record with a car powered by hydrogen.

A JCB vehicle has entered the next phase of testing as engineers prepare to attempt a new world land speed record with a car powered by hydrogen.

The Staffordshire manufacturer said its Hydromax car had completed its first test runs under hydrogen power at RAF Wittering, Cambridgeshire, ahead of a planned record attempt in the US in August.

The 32ft-long vehicle has been built to beat JCB's existing diesel land speed record of 350.092 mph, which was set in 2006 by the firm's Dieselmax car.

Powered by two hydrogen-fuelled internal combustion engines, producing a combined 1,600bhp, the Hydromax was unveiled at JCB's headquarters in Rocester in May.
