Even at -7 still getting 200 miles and its not important. I dont do 200 miles a day, it doesnt matter, I can recharge anywhere. People still worry about something that is inconsequential.
I had a diesel focus 12 years ago and would ger 65 mpg easy. Until it winter.
One winter was quite bad and I only drove a mile to see my brother and a mile back. I done that for a week, and noticed the car has used half a tank! 2 miles per day for a week and half a tank used.
Its not just EV.S. That get hit by cold weather.
If you only get 150 miles, its enough, unless you are driving the length and breadth of the country every day…its enough.
