What would be involved in converting an old SUV into an electric vehicle

This is just a thought experiment at this point, and probably will remain so. In the back of my mind I have the idea that when my old SUV finally gives up the ghost I might rip out the internal combustion drivetrain and convert it to an electric vehicle, possibly with a removable range-extender generator. Setting practicality aside for the moment, can you help me envision what this would involve? [more inside]

How might I squeeze a little extra mpg out of my old truck?

I've become mildly obsessed with trying to improve the fuel efficiency of my old truck. I've already done all the basic things and I realize that I'm fighting physics at this point, but what else might I consider if I wanted to make a bit of a hobby out of it? [more inside]

When is E85 worth it in a FlexFuel vehicle?

Our vanpool just switched to a 2014 Dodge Grand Caravan. It's a FlexFuel vehicle and we'd like to know when/if it makes sense to use E85 fuel. We live in Minnesota. Our typical commute is 40 miles at highway speeds. Environmental concerns will be weighed, but so will economical ones.

Is cruising in neutral really saving me gas?

I drive a 2003 Manual-Transmission Honda Element, and I've gotten into the habit of shifting into neutral at every opportunity, usually when I'm at the top of a large hill. I do this under the impression that this is saving me gas, but I'm curious about the specifics. [more inside]

Is it true that it is good for a car to fill it up with higher grade gas once in a while?

Is it true that it is good for a car to fill it up with higher grade gas once in a while? I usually fill up at Shell, and there is 87, 89 and 91 kinds of gas, with 87 being the cheapeast and 91 being the most expensive. I usually get 87. However, I heard that if you own a car and want it to last longer, it is beneficial to fill it up with the most expensive gas, to "clean the engine". Is that true? If so, what is the explanation behind it? I drive a 2002 Kia Rio, if that makes any difference.

look at that S car go

My friend says the fuel injection in my 2002 Jetta wagon (non-diesel) suffers if I let the tank get less than 1/4 full. She also believes that "el cheapo" gasoline, from locally-owned non-chain stations, isn't as good, or is actively bad, for the car. Is there any truth to either of these claims?

Does gasoline burn at different rates in my car's gastank?

In three cars I've driven, I get about 300 miles per tank of gas. But with all three cars, I can get up to 200 miles by the time I hit 1/2 tank. But invariably, by the time I near the 300 mile mark, I'm on E. Am I nuts or do gas seem to burn faster in the lower 1/2 of my tank? Is this mental or by design? [more inside]

Mileage on full and empty tank

I was on a road trip recently, and we fell to wondering whether the car uses gas faster when full or nearly empty. My friend said one thing, I had heard another, and harbor a suspicion that it's all urban myth anyway. Any ideas?
