2.3 to 2.5 mi/KWh is what I typically get in 60 F weather and above. Now that it is turning cooler, I expect my full charge will be a little less, as will my maximum mi/KWh. It will be a little hard for me to judge. I just switched off my 21" All Season" tires (which I use from March to November) for my 19" studless "Winter" tires. From what I have read, the 19" tires should give me better mileage. I'm just wondering how long studless winter tires will last on a car with such a high instant torque.
