Well, first off GM lied and claimed it was an electric vehicle with onboard generator. It wasn't.
The car was propelled by the onboard gasoline engine and not very efficiently at that.
So it was a hybrid. A lousy hybrid.
On electric power the vehicle had a range of 25 miles. Fine for some government bureaucrat commuting between Georgetown and K-street but ridiculous for real people.
Then of course there was the vehicle's predisposition to BURN after a minor accident. Every see lithium burn? Think thermite.
And then there was the way that GM screwed its bondholders and gave the company to the UAW basically assuring that no self-respecting republican would buy a GM product for perpetuity.
GM says it will restart production at some point but it is laying off 1300 workers from the Volt factory. Yeah, they'll be rehired. Welcome to the 99-week boogie.
