Chevrolet introduced the all-new, 2011 Volt electric vehicle with extended range, establishing an entirely new segment in the global automotive market. The five-door, four-passenger Chevrolet Volt is designed to provide the benefits of an electric vehicle without the range limitations associated with other electric vehicles in the market.
The Chevrolet Volt is not a hybrid. It is a one-of-a-kind, all-electrically driven vehicle designed and engineered to operate in all climates. Powered by GM's revolutionary Voltec propulsion system, it consists of a 16-kWh lithium-ion battery pack and electric drive unit that provide pure electric range between 25 and 50 miles, depending on terrain, driving techniques and temperature. A 1.4L gasoline-powered engine extends the range up to an additional 310 miles on a full tank of fuel by operating the vehicle's electric drive system until the car can be plugged in and recharged or refueled. This distinguishes the Volt from electric-only vehicles, which cannot be operated when recharging is not immediately available - such as during a power interruption or on a long-distance trip.
