It does, however, use one of DCX's existing engines – the 2.4L four-cylinder World Engine that sends 172 horsepower and 165 ft-lbs. of torque to the rear wheels through a six-speed manual gearbox. Dodge officials tell us a number of engines could be used in the Demon, including the 1.8 or 2.0L World Engine. A 300-hp motor, probably the one that powers the Caliber SRT-4, was also spoken of when we were initially introduced to the Demon by DCX.
