Here's two additional items to add to the list:

* Regenerative shock absorbers: MIT has a method of using hydraulics to drive a generator, eliminating the need for a mechanically driven alternator; or, to charge the electric drive batteries. These can also be used to lift and level the vehicle, to improve aerodynamics under different loads.

* Use a composite wheel/tire that has low weight, very low rolling resistance (by being strong enough to stay round), and low aerodynamic drag, no worries about inflation -- and re-tune the suspension to work with said wheel/tire. (see item above)
