    Isn’t the ring gear the wheel body (or whatever it’s called), that is, even a fixed axle would have weight there, the gearteeth even provide stiffness. CV joints also contain unsprung mass, I’d say there might be a bit of a difference but nothing drastic. With modern fancy biomimetic wheel body geometries and everything you’ll probably definitely be lighter than 80s steel rims. What happened to spoked wheels, anyway.

        Half of the hub is unsprung, the transition between sprung and unsprung is at those fancy articulating planetary gears. The drive shaft is definitely sprung, it and the motor is completely static relative to the battery and everything.
