The difference has to be in the battery side of the equation. It's gonna be bigger than the Roadster, so it'll need a bigger (at least in terms of capacity) battery than the Roadster has.
This suggests that a future Roadster model will have either longer range or less weight as the higher-capacity battery tech moves there.

But I remember quite clearly that the Roadster can go into a "half torque" mode that significantly increases the remaining range, so there is still probably some relation between power output and efficiency, though in general the efficiency of an EV shouldn't vary too much based on power.
