Is the Volt an idea vehicle that will be produced on a very small scale too small to have any impact in the car buying scene or worse still an idea vehicle that is ways off a prototype stage or is it something more serious? The battery is a critcal part of this. Toyota worked with Matsushita and Toshiba to develop its battery for the hybrids. GM needs some highly capable partners with large R&D budgets to come up with a suitable battery for the Volt but little information on this is available or GM has not really thought this part through yet.
