Not true. The CdA (coefficient of drag multiplied by frontal area) matters far more for range than the weight for range. That is a smaller EV, which may very well be heavier can have a higher range and efficiency.

The Cd matters for highway driving, but weight is the dominating factor for city driving.
As efficiency improves across motors and inverters, wouldn't regen make CoD matter more, possibly tilting it to the dominant factor again?
Regen recoups about 80% of the kinetic energy, and it is already up close to the theoretical physical limit without switching to exotic materials.
Cd will never be the dominating factor at speeds which do not produce significant aerodynamic drag.
I don’t think there’s a whole lot of room for improvement there.
