Why are there so many designs with motors mounted so as to be unsprung?
It's not a good idea, if you want a nice ride and good handling.
Electric motors of real power are heavy. Putting them in the wheels
themselves is even dumber, although it seems to be a popular choice.

How about mounting them on some sort of gimbal, or even a pivot, with
axles with CV joints at the wheels? Admittedly, et's a lot of hardware,
but as you said, at least they'd be on the sprung side.

You mean something like -- a modern vehicle drive train?

Yes, something very much like that, but with an electric motor (or two,
or four); batteries (assuming we've got enough battery technology to make
it worthwhile) and a gasoline, propane, LNG, or diesel generator.

And regenerative braking, which would depend on fast-charge battery
technology.

Thanks,
