JCB Dieselmax wins Bonneville speed record with 317 mph measured-mile

No faster diesel-powered vehicle exists than the JCB Dieselmax, now that the needle-sharp vehicle has broken the diesel land speed record at the Bonneville Salt Flats with a measured-mile speed of 317 mph Thursday. The JCB Dieselmax did two runs of 308 and 325 mph, giving an average (and record establishing) speed of 317.021. The vehicle's engine was developed by Ricardo, and Ricardo director of diesel engineering Ian Penny said, "Establishing a new Bonneville course record in excess of 300 mph is a major achievement for the team and demonstrates the power and capability both of the vehicle and its Ricardo-developed JCB444-LSR engines. We have every confidence that the JCB Dieselmax has the capability to take the official international FIA record in the next few days."
