It also loves city driving with 3.75-4.5 mi/kwh! I got mine in January as well and got 2.0 kWh without preconditioning driving about 4K in Colorado mountains. No garage to precondition in.
I am getting 3.5 or so around town in 60-70 weather, so if you need a generator in an emergency situation that would be more useful. My winter was 2 mi/kwh in a very cold colorado winter over 4K miles mostly to the mountains and back.
Get a large solar array and you can charge for free after...
