As far as motor efficiency, we haven't made any noticeable difference since the advent of AC induction motors back in 1887!
With vehicles bloating in weight to the point that at highway speeds rolling resistance is nearly half the energy loss, I'd say that weight (rolling resistance) is probably something we should be paying more attention to even if generally aerodynamic drag is a bit more of a drag.
