First winter with a Kia Soul EV here - and at -20° C this past week, after about 10 minutes with just heated seats/steering wheel on and no fan/forced air heating, it starts fogging up and my feet (even in decent winter boots) start getting chilly.
Turn on the heater and crank the fan, and watch the range drop about 3-5km per increment on the fan dial.
Our other vehicle is an old Jeep Liberty with a V6; gas mileage drops on it as well in winter - combination of some pre-warming and using full time 4WD more. I've always planned for 20-40% less range since I started driving well over 30 years ago, it is just something you do living in a truly cold winter climate.
