A fully developed active energy recovery suspension system could
ultimately overcome this problem of 'unsprung mass'. It's also worth
remembering that the suspension components themselves (spring, damper and
drive shaft on each driven wheel) form a part of this 'unsprung mass'.
Also, let's not forget the mass of the disk brake assemblies which, with
regenerative braking, can be reduced in size thus offering yet a further
reduction in 'unsprung mass'.

If you're going to put a drive shaft for each wheel connected to an
electric motor why not put the disc inboard next to it? That would
really cut the unsprung weight (to just half the shaft)

One problem with that is that it moves the disc (and pads) out of reach of
easy inspection/service.
