Andy Green, who in 1997 broke the sound barrier on land in Thrust SSC, piloted DieselMax to reach a top speed of 350.09mph, increasing the existing record set in 1973 by over 100mph. Helping the JCB DieselMax achieve this is a drag coefficient of just 0.174 and two 4.4-liter four-cylinder engines, each producing 750PS.
