HUB motor with CV Joints

[DardenneEbike]

With a 4x4 set up in mind.
I have had an idea in my head of placing 4 powerful hub motor in the middle of a vehicle and connecting CV joints to it running to the wheels. Braking would occur at the hub as well, just like on a HMMWV.
The Hub motors I had in mind where:

I'm thinking this would allow the motors to be internalized and shielded from from the elements.

Option B would be placing one in front and one to the rear of a where the transfer would be. This would let them benefit from the gearing in the axles, but not sure if the power would be sufficient.

Please let me know the pros and cons of either of these set ups.

There's an e.v maker and vehicle called Edison thats got a a few youtube videos, it uses four motors with cv's its a nice build worth a look, Its easier to use four motors there's no need for any mechanical diff's it can all be done electronically for a constant four wheel drive or even change to two wheel drive eco mode, If one motor drove both front or rear wheels so the car has two motors a diff would have to be incorporated, I think that the diff weight is better used as the extra motor as its give more torque, speed and regen ability and like mentioned an eco mode could be implemented in some way but even if fully electric braking is used in most circumstances there has to be disk brakes of sorts to stop you in case of electric faluire/emergency, but they don't need to be big 300mm + disks if they are only assisting the regen main thing is keep the weight low as possible and inboard like an rc car.

I like the idea of a reverse three wheelers like the t-rex trike one big arse motor plenty of volts and amps for a damn fast dual seater with a bit of weather coverage make the batterys the floor pan and then roll cage on top with all the subframe and engine mounts fibreglass shell.
