Yeah, the Volt actually is the real deal. We've seen several go thru the shop on testing. Everybodys first comment is the power. The prime issue I see with one and it's going to be an issue with any of them and that's in a wreck. The body of the car can become charged. Responding fire fighters, etc, can get killed from just touching the car. None of the car makers have installed an impact switch yet that would turn off the battery. The responders may take longer than necessary to extract an injured person and time maybe something the injured person doesn't have. Another issue that any of the hybrids have is the fuel tank. I hope yer keeping a fuel stabilizer in the fuel. The bug spray we buy today for gas has a stable life of only 2 weeks. After that, it can get dicey. If separation happens, the tank must be removed and the tank chemically stripped or replaced. Fires with these batteries are no more common than any battery fire. The lead/acid batteries are also known to cause fires, you just don't hear about those like the hybrids.
I'm not sold the technology yet. If everybody went out and bought one tomorrow, we'd all be walking in 2 days. There's not near enough infrastructure to support much in the of electric cars charged via a wall plug. For those that think it's a free ride, you need to know that carbon producing fuel is being generated to either make the electricity or the parts you have installed that make current. If you really want a free ride, the technology is out there, only you can't have it. You can make your own fuel from your garbage and use it in an opposed single cylinder, 2 piston headless engine, like that of Dr Pauls. The Germans are also working on a similar engine and expect to have it on the roads in Europe by 2020. Here's a vid on Dr Pauls engine....that you can't have and by the way, with after cooling, it is a ZERO emissions engine-you can breath the exhaust.
