I think an electric 4x4 would be fantastic. your guys all bring up great points, torque as soon as you touch the pedal, power to weight far superior to gas, ability to have a multiple motor set up to power each axil or even each wheel independently. an electric motor is actually far simpler and more reliable then gas. there are far fewer moving parts.

It is my understanding that a DC electric motor will run under water, can anyone (who really knows!) confirm? Also they require relatively low voltage, so its not as dangerous as you might think. They are actually using elec. motors in boats right now so they are obviously not that worried about it.

The big problem would be us motorheads wouldnt have much to play withn because once you got it together it would run like a clock and not need much from us at all.

Check this out. http://www.nedra.com/

these guys are putting up impressive numbers on electric only. granted they have no real range at that level, but it gives you an idea.

Yes, DC will run underwater. Most newn DC Motors are broken in by running underwater to set the brushes better on the commutator. Electricity will take the path of least resistance, and water does not conduct better than a metal.

Mud will not hurt it at all. they will seal them and that will take care of that issue.

Exactly. I am pretty sure Jeep would not just throw in some huge DC motor with tons and tons of voltage without protecting it at least a bit.

I have a remote control jeep that runs on a lithium battery, it can climb over a whole mound of dirty laundry!

Just take the same dimensions and increase them like 600 times bigger!!!!
(and leave the remote control!)

Just three more weeks and I'll get to see this new 'Electric Jeep' close up.

To be honest, if Jeep doesn't actually pull through on this one I might have to convert to Subaru. This will be like the 4th time Jeep has made a really cool 2 seat concept car but it seems like all they ever do is produce 5 seat station wagons. I was pretty PO'ed when management put the Jeep label on the Caliber, but when they decided to do it again with the Nitro...well I vowed that they had gone too far.

When it comes to off-roading, there is Jeep and then there is everything else. If management doesn't realize this, then they own the wrong company.

It sure seems that someone ought to be able to scale down the systems that run a locomotive to a smaller and MUCH lighter duty version that could run a full size truck, SUV or other large vehicle as well as or better than the current gas engine. It might require some re-packaging to fit everything in, but I'd love to try and do it w/ an old S-10 or Ranger. Start w/ making it work as a 2wd, then add another motor for the front and a bigger generator to charge it all, then it's just a matter of scaling it down to fit...

They did it with a 4wd evo lancer and it pumps out 200kw and 518nm of torque... it will happen eventually

why use a gas engine? they're terrible for running electric generators. a diesel will run at a steady RPM for FAR longer, get a decent small block detriot, mount that right behind the seats for a good cog, fill the front cavity with batterys, add 2 electric drive motors to the drive shafts to the diffs. (for simplicity of build).

givver!

new problem, needing to replace rubber alot more, being able to floor it and instantly having the wheels moving at full speed will be a hard thing to adjust too, may want to add a computer assist to control the driving styles etc as well as moniter the system.

it would be a pretty fun jeep though

Someone made a mini conversion that has an electric motor powering each wheel, taking up not much more than the space where the brakes were in the real mini.
This would be a awesome setup for a 4WD, provided the motors can be made submersible that is.

Too bad not all motors would spin the same speed. Plus they will wear differently.

Slick101, good point. You could probably actually hook up some sort of alternator to power a heater, but then again there is no such thing as unlimited free power. (recharging a battery running a belt spinning an alternator.)

Actually, each motor would probably be controlled independently. I'm a CNC machinist and part of that job includes knowing exactly what speed to program the spindle; compensating for tool wear, matl. hardness, ect. In theory, an Electric 4WD could have one tire doing all of the work or spread out the work load to any combination of tires...with a very marginal error. In fact, I'd bet a round of beers that an Electric Jeep could give an amatuer driver considerable more control than a convential Jeep (preprogrammed off-roading parameters). You could take it one step farther and let the 'hard-core' off-roading tweek and manage performance in a whole new way.

Who knows, it may very well be the wave of the future.
