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]

My car weighs 4013lbs (with me in it) and averages 17mpg on my 21.7m (roundtrip) commute.
My gas tank holds 20 gallons, but I only ever fill it up half-full. The reason I do this, is because my brain knows how heavy 4 x 2.5 gallon containers of water
is, and thinks that not carrying this additional approx 60lbs of weight (1.5% of the 4013lbs) will be better for both mpg and performance (i.e. less liquid sloshing around the tank). Is my brain crazy?

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]

New Jersey gasoline is more efficient than Massachusetts gasoline? I seem to get much better gas mileage with both my cars when they are filled up in NJ. What gives? [more inside]

Simple tricks to improve MPG?
For instance, I've thought about removing the rear seats/internal molding to lighten my car. I've also thought about aero-improvements, such as moon-disc wheel covers, or even somehow making a cover over my rear wheel wells. I'll be removing my rear wing this weekend, but what other tweaks could I do? [more inside]

Last night on ABC news there was a guy with a VW beetle (silver) who put a wicked-huge wing on the back and claimed some ridiculously-high MPG figure. Alas, my google fu fails me. Why would this wing possibly work? They guy wasn't a tuner, AFAICT.
