I just did my first winter trip to Jaffery, NH, it was 11F in NH and a relatively balmy 17F back home in MA. I left with 91% in the battery, returned with 42%, used 49% of the battery capacity.
33KWh/.49 = total capacity 67.34KWh
Maximum range 67340Wh/326Wh = 206 miles
Power per mile is almost exactly 100W/mile higher that this trip in the summer, that's the heater penalty. I never measured the battery capacity in the summer in this way but assuming the reported capacity of 75KWh is correct then cold weather diminishes the capacity by about 11%. All if this is as expected, winter range is 1/3rd less than summer range.
