AutobogGreen brought this to my attention. . . http://www.gm-volt.com/2007/11/14/my-chevy-volt-question-to-bob-lutz/ The funny part was the comment about aerodynamics. The more important part was that GM is "fully committed" to Chevy Volt production and no longer sees much likelihood that battery technology will be a hindrance. It's been great to see how GM's (particularly Lutz's) attitude has changed over a relatively short time. When they first showed the Chevy Volt, the talk was all about how this represented something they'd like to do someday but "the batteries don't exist yet". That brought forth a lot of skepticism and even ridicule. After the huge public response, I think GM felt compelled to look closer at the idea, and the closer they looked the more doable it seemed to be. You can follow the changing attitude in their public comments, which started out very timid and full of caveats and disclaimers, but every new comment from GM has been more confident than the one before. Now they've reached a point where batteries don't look like a problem, and Lutz is talking casually about producing up to 100,000 units in the first year. If it even hits a quarter of that production level it'll send a shock wave through the auto industry.
