2017 Bolt EV with 103,000mi. Battery was changed in April. During the peak summer I was getting roughly 300mi of range.
Currently the temperature has dropped from 80 to 20 degrees f. My range has dropped to roughly 140mi non-highway driving. To add to the loss, the CC2 tires have dropped it roughly 15%. A little nervous with subzero temps approaching, but a fun ride.
Technically ice engines run better in the cold. They make more power the colder it is. The cold air is more oxygen dense. This is especially true for turbo engines.
Winter gas(petrol for nonUS readers) in the US negates any positives. Also more air = more fuel and terrible winter fuel = terrible mpg.
