Yes - Rubicon! I think I see a front diff! I hope someone thinks to get some photos from the under side showing more detail, esp the rear...
From some of the earlier spy photos it does have a front axle (no IFS), but it did look like they were CV axles instead of a ujoint at the knuckle

Thanks for 12 entertaining pages! But, the guys from the old Top Gear already figured out electric cars and perfected one - remember the Geoff?

This is cool and interesting but not for me. If I'm going electric, I'm going 100% electric. I also want at least 500miles of range.

Giving it Supercharger compatibility would help as well.

Thanks for those pics. Would be good to get one underneath the front as well, so we can see what base motor we're dealing with.

They did a pretty good job locating the batteries. Looks like still an equivalent size gas tank as the non-EV models, which is good. You can see the coolant lines for the batteries draped around the frame rails.

I think from earlier spy shots we also saw that the front axle will have CV shafts.

I think you guys are on to something here. I would like to see a full electric Wrangler with an on-board ICE to charge the batteries. Sort of like the diesel-electric locomotives. You could ditch the transmission completely, and possibly even the transfer case.
This is how the BMW i3 works. There's a 33hp scooter engine in the trunk. It has no connection to the drivetrain, it only charges the batteries.

The problem is it doesn't do it quite fast enough. The BMW i3 is VERY clever, and they made the thing super lightweight (relatively) by completing rethinking the design and manufacture from first principles. The passenger module is a carbon-fiber / plastic composite, the door panels are glued on, the interior panels are made from hemp, the tires are custom super narrow things that look like they belong on a motorcycle more than a car. The whole thing is weird (and awesome) in the name of weight savings. Meanwhile the car doesn't really do a great job of keeping up with demand if a) you're running the heater + b) at highway speed + c) experience a sustained incline. In moments like that, the buffer between what the batteries need to sustain output and what the motor is able to supply goes into a net negative, and the car has to go into a turtle mode (limiting to 45mph and reducing climate) so that the motor's "buffer" can catch up with energy demand.

I mention this because the Wrangler would not benefit from all of this engineering and would simply be heavy, and so clearly the generator would have to be bigger and at what point does that generator become something approximately equivalent to a 2.0T? That's the question I'd love for an engineer on here to answer.

Super interesting to think about though.

I've heard this before, but never really looked into it. Does it retain the CVT from the scooter to power the generator? I can't find any photos that show otherwise. If so, it seems like a terrible decision, as the CVT would loose around 25% of it's efficiency before any generating is actually done. Either way, I was thinking the range extender would be more for slower speed off-roading than freeway speeds.

After seeing how the ZF transmission incorporates the electric motor, I'm actually pretty impressed with their design. https://www.zf.com/products/en/lcv/products_50899.html

You are spot on. This is the exact reason why, although EV vehicles have been around for a century and a half, and ICE vehicles for nearly as long, nobody has made a successful business model out of combining the two in any application other than light duty personal transportation.

Uh, locomotives?
