Here is a hub motor by NSK containing planetary gears and a way to select ratio. (NSK is usually a manufacturer of wheel bearings etc.)

Hub motors would add quite some weight to the wheel hub / carrier, and it will be a challenge to find space without full re-design of the suspension parts.
Have anyone looked up Ford's patent to see what they actually are trying to limit others from doing?
