The Subaru HM-01 Hybrid Concept is powered by a four-cylinder engine that displaces 658cc and mated to a CVT transmission. The 45 horsepower and 43 foot-pounds of torque produced by the engine are sent to the front wheels, while a 42 volt electric motor powers the rear wheels. While in motion, the momentum of the rear wheels is converted into electric power by a high power 3kW alternator in the rear drive unit and re-charges the batteries.
