100% torque at any RPM.....Why?

Unless you are running around your own property, it sounds like "I ran out of charge and my friends had to tow the heavy pig back". If you want it for economy it might be one thing. If you want torque, install a diesel.100% torque at any RPM.....
Its a rock crawlers wet dream.
Ill be following this.
Stinking, rattling diesels out in the woods aint my thing. If one shows up to wheel with us, they have to be at the end of the line. And a new guy gets stuck being in front of them.

Anything can work but you are talking many hundreds of pounds of batteries. Batteries are not cheap and they age. A good gas of diesel motor lasts many years and if you do not use it, it does not degrade like electric batteries will. If it is what you want, more power to you. I like the security of knowing that I can carry 5 gallons of fuel as a reserve for my 20 gallon tank and I will be able to make it back to the road even after a long day.Stinking, rattling diesels out in the woods aint my thing.

On an average trip, we do about 10-15 miles. I burn about 10 gallons of gas, depending on terrain.
I think it could work.
I love the idea of electric vehicles. But I think the resistance here has to do with the fact that the CJ is extremely heavy, but has very little storage. That link you had of someone with an Electric CJ5- it was a fiberglass body on a VW chassis, and he still had to charge it at every short trip.I do not want to start a debate on ecology. I chose to make an electric jeep for the challenge.
My thought on how to do it simply, would just be the electric motor coupled to a manual transmission and transfer case. That way you could pick the optimal RPM range for the motor to work in while crawling. Being able to lay out the batteries for weight bias would be a big plus in a crawler.l am all in on this. I have also wanted to do this. I am in the battery market sector (Li-Ion) and I think this is a fantastic application particularly rock crawler for the reason Skiz Riz pointed out of 100% torque at any rpm. You will not need near as much battery as a Volt/Leaf/Tesla as you really don't need the range or speed of these vehicles. I am curious of your choice of motor and number. It may may make sense to go with hub motors at each wheel but I have not found any that were durable / cost efficient. I think it definitely makes sense to go Li-Ion as I think you could go with about 12 kWh and probably keep the weight under 1,000 Lbs.
My budget for this project is $ 10,000.---. How much are you willing to throw at it? ---
I'm interested as well.I hope you can pull it off, it's an interesting project. With today's small and powerful electric motors and batteries, there's no reason you can't.
