Not a new idea, military trucks used reduction gear drives in the wheels before WWII. Edit: Portal Gears.

One downside to doing this is adding unsprung weight, which is not a good idea.

And it will still need a CV at the wheel to accommodate suspension travel.

    You're right on unsprung weight, this is going to add quite a bit, especially if you fill the thing with oil.

    Not sure how you still need a CV though, as this performs that function. Watch the video, there's a good animation. Basically this is a reduction gear and CV joint in one unit.

    Camber. It allows the wheels to tilt allowing them to keep their entire tread on the ground when only one side of the vehicles suspension is compressed, like during a turn.
