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.
It’s winter here in Seattle (more or less) so that means temps in the mid 30s to low 50s. So far I’d put the range loss from the weather at something like 10%, not really a lot.
My config does have a heat pump, if that matters.
