Given all other factors that normally influence range, I do not believe you will be able to tell.
Weight is less critical to EVs than ICE because kinetic energy put in can be largely recovered again. There is no inefficient engine working hard to push energy into the chassis only to lose it again as heat in braking.
As a matter of comment, IMHO, the future for EVs is that they will get much bigger and heavier, because they do not succumb to the inefficiencies of heavy cars like ICE do, and by making the car linearly D% bigger you get D^3% volume (thus potential battery carrying capacity) increase.
