Today I kind of tested the high way drive efficiently at cold weather (it is cold but not coldest in GTA).
I drove from Markham to Pearson this morning. Outside temperature was -14C, inside temperature set to 19.5C, and three seats warmer turned on for two bars, speed is about 110km set on AP. See the picture for the return trip, the efficiency was about 60%, that means in this condition for a full charge Model 3 LR range could be only 300Km. (BTW, I prewarm the battery before departure and only did drop and go at airports).
