Holy mother of cold weather range reduction...
I’m at the 1st charge stop. Prior to leaving I charged the battery up before heading out and charged to 97% and headed out.
Temps are mid 30’s and 1st stop is 90 miles of driving. Just arrived with 42% battery left.
That’s a 55% usage for 90 miles of driving. Kept the speed at 70 mph almost the entire way.
This leg of the trip does have a small’ish mountain and it is cold but 55% for 90 miles? Cabin temp set to 65 so I don’t think the heater is causing any extra drain.
5 charge stations here, one down but only one other M3 here charging so all good there.
I’ll update at my next stop which is about 110 miles but flatter...
