Last couple days I've been driving mainly around town on 35 mph roads. Did one stretch at 55 mph for about 24 miles. Checked miles and Ah used before starting the charger tonight: 71.9 miles, 108.1 Ah, or 1.50 Ah/mile. That indicates a range of about 95 miles at those conditions for my 180Ah, 20.76 kWh pack. Just multiplying by the nominal pack voltage of 115V gives 173 Wh/mile, or 195 MPGe. It likes warm weather.
