Interesting. It's been pretty cold this week. 5F one morning this week, teens and 20s every other day. I've noticed that as long as I have range mode off and a decent SOC, I've been pleased with the heating. The preheating from the app works much faster than before. I typically preheat to 74, get in the car and turn it of relying solely on seat heaters...until either it gets too cold (rare) or the windows fog up, then I set it at 64.
