In the end, unless you're down with having the cabin be freezing during your drive, you're going to spend a good bit of energy warming the car. This energy was "free" in an ICE, but it has to come from somewhere in an EV, and that somewhere is the same place as where you get your range energy.

  It's the second one, and ICE typically uses energy that is otherwise wasted when it isn't cold outside. Mind you it has the effect that it takes longer to warm up an ICE car because you need to warm up the engine etc. before the habitacle gets warm where you cet there very quickly with an EV.

Yes but once the car is warm, it doesn't consume that much to keep température unless you open the doors, at least on my 2019 Tesla 3. I found that pavement conditions, how much snow and ice is stuck to the car etc. have a bigger influence on range than temperature once the car is warmed up. The trips I did during or just after a snowstorn always required some careful management of charge and keeping a good buffer.

  I do agree, snow/ice stuck to the car changes the aero drag a good bit and pushing slush definitely adds a lot of tire drag as well. This can definitely be a major factor. I live in an area where it can get pretty cold, but usually in quick cold snaps and rarely a lot of snow on the ground. I've found preheating when plugged in completely negated the extra energy needs on shorter drives, but the longer 100mi highway drives still ended up needing a lot of energy to keep the cabin warm. And yes, it takes a ton of energy to go from a freezing cold cabin to warm compared to trying to keep things warm. Every time you stop for a few hours and then go again without having any external power to preheat you use a lot of energy.
