Looks pretty good, actually. 
But I've watched Who Killed the Electric Car recently, and now I'm left wondering what's taking GM so long? I had no idea the technology had been so far advanced ten years ago... with that in mind, it seems crazy there isn't a Volt on the road already.
I keep thinking about the 'getting to the moon' issue. The US of A, the first country to do it with slide rules, a couple of computers the size of a football field, and remedial-at-best launch and return program, sez it'll cost a BAHzillion dollars and 10+ years just to GO there, much less have anything remotely looking like a base.
Worst case:
1. Pull out the 40 year plans your great-grandfather at NASA drew with a No. 2 pencil. Hopefully the cigarette ashes (after all, you would smoke at your desk back then) didn't burn too much of the knob-and-tube wiring schematics.
2. Build the thing - it worked 6+ times before.
3. Add upgraded 21 century technology.
4. Go.
If 90% of the cost is development, and you've already got a proven system, USE the %&*%&*(%^& thing, even in upgraded form.
The shuttles are perfect examples of 30 year old technology being ket aloft by upgrades to it platforms.
