Heating in cold weather and poor insulation ?

[Schulmann]

My 2020 model cant heat enough when weather is cold: -14c wind 50km/h heating maxed. My M3 uses 280mwh/km !!!! Dry weather but cloudy.

The heater works but I have the impression that I lose heat because of poor insulation.

are there some critical places where a little foam insulation can help ?

This is a pain point for all models. Even in my S I can feel coldness on the side of my left leg. It could certainly use some insulation. I'm not sure if sound deadening materials have any R factors but if so that could be a 2 for 1 in also helping with noise.

I keep eyeing aerogel for this application

Yeah, glass is a poor insulator. Covering all the glass areas with bubble insulation may help.

Here is a little update ( Temps is below -10c) On highway (70 km/h) heater M3 can t keep up with cold. However in city driving (stop and go) I dont have any issue !

I dont know if it is an insulation issue or a battery output problem.


Preconditioning only delays the issue.
