I must say that it's an excellent wintercar. The tractioncontroll system is way better that my other bmw's.
The range calculation seems to be accurate with the temp.
The best is preheating from the connected-app or remotekey. Works with or without the chargingcable plugged in. 15min and the car is warm and cosy
The only thing that i'm missing is the stearingwheel heater.
I was a little worried of the brakeregen icy conditions but the tcs handle that with no supprises so far. The
2017lci update included "50-times faster responses for greater traction and driving stability in adverse road conditions and while
brake energy recuperation."
Haven't tried any deep snow conditions yet
