The Chevrolet Volt is GM's first plug-in hybrid model capable of traveling 40 miles on battery-only power. Any further, and a 1.4-liter four-cylinder gas engine kicks in. At slow speed or stops, a regenerative braking system charges the system. Standard features include OnStar, remote keyless entry, navigation, satellite radio, Bluetooth, cargo cover, Bose audio with 30GB hard drive, and seating for four. Pricing starts at $39,145.
