The Chevrolet Volt is a plug-in hybrid electric vehicle being produced by the Chevrolet
division of General Motors and will be launched in November 2010 as a 2011 model. Its propulsion system is based on GM's new Voltec (formerly known as E-Flex) electric automobile platform, which differs significantly from GM's earlier BAS Hybrid and Two-Mode Hybrid systems. The Volt is capable of traveling between 25 to 50 miles (40 to 80 km) solely powered by the electrical energy stored in its on-board battery pack.
