Your post said 80 miles daily commute. If one drives very little, the Volt is overkill, IMO. The value proposition just isn't there. If one drives 80 miles per day, the Volt isn't gaining you much over the lower priced Prius. It's sort of a bastard-child surviving in a niche market until someone(most likely Tesla) makes an EV in that price range. Then there will be a ton of imitations(see smart phone market), and a few Kodak's(short sighted companies always fail).
The narrow range I think Volt makes most sense is if it is your only car and you can stay in EV mode a very large percentage of the time while still giving your flexibility for longer trips. For an 80 mile commute a Prius does make more sense most likely.
