I'm actually most concerned about the lifetime of the batteries. From what I've read, the batteries top out at 8 years, and presumably degrade before that. As the $20k Chevy Cruze is the same chassis as the Volt, I guess the batteries come out at ~$15k. That's a huge amount of money to renew use of your $40k car after 8 years (unless you see that $15k as some sort of investment in the environment).
The Volt design could/should succeed. But not with battery tech where it is. Those batteries need to do 10--12 years.
