Autoblog drove this, too. Personally, I'm done with the Volt. If they manage to come out with a finished product, it will still only seat 4 and cost too much...and it certainly won't save GM. Toyota has sold over a million Prii and the new one is even better than the first - and yet they still experience quarterly losses in this Carpocalypse.
The Volt may well end up being only marginally more successful than GM's current listless phalanx of hybrids, and I forsee the typical GM fiasco of having either too many or too few on dealer lots, with resulting price-gauging or incentivizing.
