A lot of attention is turned to more efficient ways of heating up the cabin like heat pumps, using waste heat from motor(s) and battery etc, but I don’t see as many people talking about another important factor which is how well the car is insulated. Are there any companies which claim their EVs are better insulated than others or something like that?
Cost of heating the cabin is pretty negligible compared to the amount of energy you use while driving. I’m not even sure it would be worth the added weight.
