A Reuters article in Planet Ark quotes GM's product chief and Vice Chairman Bob Lutz as saying that GM has set 2010 as the target date for introducing the Volt.
Lutz said the major uncertainty facing the Chevrolet Volt, a concept vehicle GM unveiled in January, was whether lithium-ion batteries can be developed to power it economically and safely.
A running Volt prototype is expected by the end of 2007.
GM has said it is aiming for the Volt to be able to run for 40 miles on pure electric power, meaning many commuters would be able to get through a day without using gasoline.
Lutz said GM's initial work had shown that the production version of the Volt would have to shed some of the bold styling cues of the concept, including the extreme front placement of the wheels.
