Hi,

I have been driving my ID3 58kwh model now over 11000km. In winter times the heating really beats the mileage. In summer heat pump uses 2 kwh but on winter easily 4 kwh or more. That just sucks. I will do something to solve this problem. Most of the cold comes from windows. You could swap all windows to acrylic, but that takes lot a time and taking doors open in this car is not easy task.

Other option would be to put plastic films on all windows which would help little maybe 20% or so.

But lately I figured even better and more effective way to solve this problem.

At the moment I almost always need only the front seats. So all rear windows are cooling the cabin without any sense.

I will build a wall from about 60mm think semi hard mattress. To see back I will cut there a opening and put between the mattress 3mm acryl window there.

This will more than half the heated interior volume and more than half the cold window surface area. I am betting I can see a difference in real life driving.

This would also create real two zone climate inside the car as I can control the temperatures little bit separately through the leg heating function.
