5.2 miles/kWh has been my average since buying the car in July. This includes AC use. Now that the mornings are getting chillier here in New England, I've started using the heat on the automatic climate control (set to 74F). I've noticed in my Drive Info screen that my range has dropped to about 3.2 miles/kWh. Just curious how this compares to the experience of others. I'd be particularly interested in knowing if our northerly neighbors in Canada who have heat pumps see better performance.
