I saw one of these at an arms show on Fort Benning and it had a diesel engine that powered a generator. The generator then gave electricity to a motor on each of the 4 wheels. The guy said one wheel motor will pull the vehicle at 60 mph even if the other 3 motors were destroyed. Pretty sweet rig if you ask me.

check out this site, http://www.revconversions.com/

They have a totally electric TJ, with a trailer mounted generator to boost the range.
I think if you search youtube, they have some videos about it.

what are the advantage of having 4 electric power hubs on each wheel?

Also, who said the chemical exchange had too happen in the Jeep? Couldn't "power stations" be readily available like gas stations, maybe instead of paying for gas you pay for a battery exchange or we develop a way of charging batteries in 5ish minutes, plus we could have a solar charge and add a sort of windmill to the front so batteries are being charged while the vehicle is moving. convert the heat from braking back to energy for the battery, there are a lot of technologies out there that could be combined to make one awesome vehicle.

Chris. I miss driving my Jeep. Can't wait to get into another one.

I am not sure of on all 4 wheel. I would guess for 4 wheel drive. Having the motor attached at the wheel probably has a few advantages. First in no transimission. Three advantages to that; first one less assembly. 2nd no loss of power by going through a transmission, so better efficiency. The third is that a motor if reversed is a generator. So, the motor can act as a brake and then regerate electricity to the battery.

Motors on all 4 wheels really wouldn't be that big a deal. From what I know about CNC motors, the possible control over how each one of the wheels performs is virtually limitless. If you wanted to get really crazy, you could have 4 wheel steering with your 4WD. It'd be the ultimate in short area maneuverability with incredible torque!

I'm curious to see how rising gas prices affect the future the Jeep lineup. I would really love to see a small diesel/electric 4WD.

I don't think it will be long before we see a production hybrid Jeep thats still capable of the power and torque a jeep has now.

Imagine the clearance problems that could be solved with four electric motors at the hubs. No more transmission or transfer case means more room under the belly, and no more differentials means you wouldn't even need a straight tube between the wheels—you could put in a solid yet bent axle that curves up and gives clearance straight down the center of the vehicle. No gas tank, no oil pan, no driveshafts. That would be awesome!

In addition to guns and Jeeps, I also like photography. Some of my work can be seen at www.pdbreske.com

Also, think about the possibility of torque at very low RPMs.

Why not?
You can enclose the motor, and set up a fan/blower with a filter, to keep the motor cool, and keep debree out. And just like a regular vehicle, if you are going to be in deep mud/water, just waterproof the electronics.

I think the benifit of maximum torque at low/0 RPM would be worth any extra work to seal/protect the components of an electric off roader.

in a military application, the 4 motors allows the vehicle to continue its mission if one is blown up or shot out. The rep on site said that one motor will pull the vehicle at 60 mph so they can lose three and still keep on keeping on.
