The record-breaking JCB444-LSR engine displaces 5-litres, weighs 382kg (dry), and produces 750bhp at 3,800rpm and in excess of 1,500Nm of torque at 2,500 rpm. Two engines were used to set the new record at Bonneville Salt Flats USA in August 2006, with a total power output of 1,500bhp. Yet despite having twice the power and more than four times the weight of an F1 car, DIESELMAX had only half the fuel consumption.
