I'm really interested in the Volt. Albeit I won't be in the market for years. I can't afford to take a chance on a car that hasn't had the kinks worked out yet, so I guess it's good I won't need a new one for quite some time.
My understanding of a hybrid is that it switches to gas whenever you are driving over a certain speed. I remember hearing it was 35 mph, but just now I was looking at this site...Car Talk, and they are saying for the Fusion it kicks in at 47 mph.
Unless I'm on a side street, going to my house 4 blocks away from a main road, I'm almost always going over 35 mph. In that case, I don't see the benefit of the electric component of a hybrid at all. I don't have a lead foot or anything, but 35 mph on the roads around here is pretty slow. I'll check today going to work, to see just how fast I drive down Lamar, keeping up with other traffic.
At 47 mph, well, that helps, if I'm going to be doing little multi-lane highway driving.
I'd say over the last 15 years, the bulk of the mileage on my cars has been on highways where I'm driving 60-65 miles an hour. If I had a 15 to 20 mile drive to work, maybe 3 of those miles would be at the slow in town speeds....even then that means driving anywhere from 40 to 50 mph, 35 if it's a really small road, or a lot of lights.
That said, I would opt for the vehicle that would give me the most mileage in electric.
