The Chevrolet Volt is a plug-in hybrid electric vehicle to be produced by the Chevrolet division of General Motors and expected to be launched in November 2010 as a 2011 model. Its price is estimated to be near $40,000, which would give a net price of about $32,500 after the $7,500 Federal tax credit. The automaker has kept the Volt on or ahead of schedule, despite GM's Chapter 11 reorganization.
Volt's propulsion system will be based on GM's new Voltec (formerly known as E-Flex) electric vehicle platform, which differs significantly from GM's earlier BAS Hybrid and Two-Mode Hybrid systems. The first pre-production test car based on the full Volt design was built in June 2009 in Warren, Michigan[6] and by October 80 Volts had been built and were being tested in various conditions.
For up to the first 40 miles, the Volt is powered by electricity stored in its on-board lithium-ion batteries which are charged by an electrical power outlet. The Volt's 16 kWh (8.0 kWh usable) lithium-ion battery pack can be fully charged by plugging the car into a 120-240VAC residential electrical outlet using the provided SAE J1772compliant charging cord.
No external charging station will be required.Unlike most current commercially available electric hybrids, the actual propulsion of the Volt is accomplished exclusively by the electric motor.
With fully charged batteries, enough electrical energy will be stored to power the Volt up to 40 miles (64 km). This distance is capable of satisfying the daily commute for 75% of Americans, whose commute is on average 33 miles (53 km).
After 40 miles (64 km), a small 4-cylinder gasoline internal combustion engine creates electricity on-board to 53 kW (71 hp) generator extend the Volt's range to over 300 miles (483 km) The electrical power from the generator is sent to either the electric motor or the batteries, depending on the state of charge (SOC) of the battery pack and the power demanded at the wheels. The distribution is controlled by the electronic control unit (ECU) of the vehicle
