An local off road guru I know of is wrapping up an electric 4x4 buggy build. Just watched a video of it driving in his yard. It’s cool as F
Does something like this have or need a transmission or a 2 speed transfer case? In my first post, the linked article mentions bolting the motor up to a manual transmission, but not an automatic. I don't understand why a transmission is needed.Video of the video but you get the point.

I have no idea honestly. I’ll ask him for some more details.
Looks like he is running an auto and dana 300 looking transfer case. I need to do some more homework on the different electric vehicles to understand how they work better. Here's a picture from his build.Tesla doesn't. Though there seems to be a single gear reduction at the motor.
I ask because of weight. I'm wondering what the weight difference would be if we could somehow put a Tesla battery and motor into a TJ today.
The Model S battery is 1200lbs. The motor is 70lbs. Let's make a wild guess that everything including the wiring, coolers and computer stuff is 1700lbs.
515lbs Jeep 4.0
12lbs motor oil
130lbs NV3550
114lbs 19 gallons gas
20lb gas tank
15lb radiator
22lbs coolant
10lbs wiring
===
838lbs of ICE stuff that gets removed.
What else is there that we can get rid of?

You're right. Hard to see on mobile. Just booted up the laptop to help me bad eyes.That looks like a manual transmission to me.
The transfer case I get, at least the 2/4 part of it. I don't understand what the transmission is for.
One major shift that needs to happen is hot swapping batteries. It’s ridiculous to expect that someone waits at a supercharger for a few hours vs a pump for 5-10mins.
Looking at the gas tank area and for the purposes of convenient swaps, wouldn't it be great to put a big battery there?
As long as it’s got loads of armor!

Wonder if that buggy has a "tuned down" electric motor. I couldn't imagine trying to deal with "0-rpm" max torque off-road. Seems like a recipe to snap a whole lot of driveline components.
One of many things I wish I understood better. Wouldn't something like a torque converter be beneficial? And even moreso for an off-road e vehicle?
Regarding range, charging and infrastructure, that is something I am ignoring for now. I trust that things like that will sort themselves out as the vehicle itself becomes increasingly viable.
