63 Willys CJ5

Have a 63 that is really only frame, axles (5:38 gearing), body, transmission, t-case with O/D. The axles are attached with steering an brakes. It is in rough condition, don't think it's worth rebuilding.

What I thought about doing, was to go "green" with it. ( I'm of the belief man made global warming is B.S.). My idea is to use an electric motor powered by a small generator. Since its already striped, it's fairly light. That coupled with the low gearing and Warn overdrive, I figured it might make a good commuter vehicle. If it ends up getting good enough mileage, maybe even be a good light duty 4X4.

Comments please.

start a build thread. this is something I've thought about for years, but never did anything about. I know I'm not the only one. Good Luck perhaps an automatic transmission (maybe Ford C4) might work . The reason for the C4 is that it's short, and it keeps your drivelines longer. And, it doesn't take the horsepower that GM transmissions do. Crap, now you've got me thinking..............not necessarily a good thing. again, good luck

I wouldn't want to tease with a build thread that will never get built. As for the trans, I have done some research over the past year or two and they all say to use the manual trans.

Unless you plan on making aerodynamic changes, as well as a tricked out battery pack, the generator/motor option will not be any greener than a gas engine.

The generator is burning gas/diesel at something like 25% thermal efficiency to do work, which is being reduced roughly another 50% by the rotational to AC conversion at all times. When you are sitting idle without a battery pack to charge, the generator is just wasting fuel. When there IS a battery to charge, it is losing additional efficiency to heat transfer during the charging process AND a conversion loss from AC to DC for the battery/motor.

Wranglers get crappy fuel economy to start with due to their brick-like profile. A hybrid wrangler would get crappy economy due to its brick-like profile AND multiple conversion losses. It WOULD be pretty nice for crawling though, if you went with a beefier motor. Electric has the benefit of being able to deliver 100% torque at zero rpm...

I wasn't trying to create a super commuter. I live 1,25 miles from work and maybe running around the neighborhood. I was thinking along the theory lines of a locomotive- a generator powering an electric motor. I only need to move approximately 1 ton to a max of 40 mph using as little gas as possible
