The heart of the Chevrolet Volt is its exclusive Voltec propulsion system, the world's first plug-in, electrically driven, extended-range system in a production vehicle. It delivers ultra-high efficiency unlike that in any other vehicle, with between 25 and 50 miles of pure electric driving (depending on terrain, driving techniques and temperature), and an onboard Ecotec 1.4L (LUU) gasoline engine that extends the Volt's range to a total of up to 379 miles.
Importantly, the 1.4L Ecotec engine does not provide drive power to the wheels. That's accomplished with a 111-kW (149-hp) electric drive unit. Positioned under the hood next to the engine, it packages a pair of electric motors and a multi-mode transaxle with continuously variable capability. The engine serves as a generator to provide power to the vehicle's electric motors.
