Chevy has announced their next generation EV/PHEV named the Volt which will use their new E-Flex Series Hybrid propulsion system and be based on the Cobalt chassis. The E-Flex system is designed to integrate into their next generation of vehicle platforms due in 2009, and capable of using bio-ethanol, bio-diesel, or HFC technology for the electric generator. The genset in the current Volt concept uses a turbocharged 1-liter, 3-cylinder engine coupled to a 53 kW generator which is capable of maintaining 100mph or delivering about 50mpg at more moderate speeds. The Volt will be a front wheel drive pushed by a 120 kW (160 HP) motor that develops 320 Nm (236 lb-ft) of torque, for a top speed of 120mph and acceleration from 0-60mph in about 8.5 seconds. With it's 16 kWh Li-ion battery pack the Volt will have 40 miles of EV-only range and recharge in about 6 hours at home from a 120vac 15A outlet. The batteries are expected to be kept within a 30% to 80% window much like current hybrids. GM is working with battery makers Cobasys/A123Systems and Johnson Controls/Saft to develop these batteries. The batteries are arranged in a spine down the center of the car's floor much like the GM EV1. With it's twin 6 gallon gas tanks and a full charge the Volt should have a 640 mile range at 70mph consuming about 12.8 gal.
