    If you are in a traffic jam, you lose range because of the heating. For gas cars, that doesn’t matter at all.

      A 1kw heater (less, given they’re all heat pumps these days) isn’t doing squat to the range compared to an 80kw motor.

      A gas car has to idle its engine to get heat. It’s burning fuel constantly… that’s why you frequently see broken down gas cars in heavy traffic.

        From cooling the engine. When you are standing still and the engine is running it consumes about 1l/h. I just looked up some numbers for EVs: 100kWh battery, heating takes 1kW for every 10K temperature difference, so 3kWh in -10°C. Its higher if you use additional stuff like the heating for the seats. With 150kWh/100km consumption you lose 20km every hour you are in the heated car. I would say that’s a noticeable difference compared to no heating. I also checked how much an AC takes in summer and its about 1 to 2kW for 30°C.

            The answers to your question is already in my post and the 150 was obviously a typo, because the loss in range checks out. It should be 15. AC uses less because the temperature difference is less.
