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?
I can tell you that the quietest EV I’ve driven is also the one with the worst efficiency, Audi etron, and that’s probably for a reason. It is incredibly solid.
