>If you use 1 motor per wheel, at full torque you don't have double the power but the same power as one motor on the axle.

That's like saying if you double the power of an engine you get the same power at the wheels? The limiting factor is the grip. The more power you add the more you get out until that limit is reached.

But anyway, I'm not sure the one motor per wheel is all about more power. You could use 2 smaller motors instead of one large one. And then you can get rid of the axle and diff which are weighty items, so I don't think it's necssarily the heavier solution.

Plus there's ground clearance. The diff is often the lowest point in an offroader. A motor at each wheel removes that limitation.

Then you've got packaging. A centrally mounted motor uses space that could be used for cabin space or batteries. Hub motors are using otherwise dead space.

Then there's reliability. If you lose one motor you've still got another to get you somewhere, and it's probably easier to replace too.

Thank you. I oversaw the aspect of what happens until the motors reach max power and all the other aspects you have mentioned.
