Why not develop an axel with an integrated motor? It’d be easily scaled to any vehicle with a solid rear axle. Fill the engine bay with batteries… It seems like an easy approach to get a widely applicable EV conversion kit. Offer a few widths and diameter axles… Is it bad to have the motor in an unsprung position?I see hub motors, so I think not. I guess air conditioning would be another thing.
If you look into it, you’ll find that something like a Wrangler Rubicon can actually produce more torque thanks to crazy low gearing. It can only do it at speeds so low that it is only useful for off road rock crawling at a walking pace, but it does it it with drive shafts and differentials that aren’t very special and don’t explode.
