The thing with weight savings and aerodynamic drag is that in the beginning these didn't play much of a part in efficiency because engines used to be so inefficient. But now that we're getting closer to 90% efficiencies in EV's the only way to improve efficiency will be through aerodynamic drag and rolling resistance improvements.
Of course the other way of thinking is that with engines and motors being so efficient, who cares if the vehicle is a rolling wind brick.

Why are you mixing all those characteristics together? I didn't say that aerodynamics does not play a role in vehicle efficiency. On the contrary, It is the biggest component at high speeds! Weight does play a role in efficiency but the difference in weight between conventionally affordable materials like aluminum and the exotics and expensive carbon fiber is negligible!
As far as motor efficiency, we haven't made any noticeable inroads since the advent of AC induction motors back in 1887!
