Here in MN with a noisy gearbox, winter tires and no heat at 13f I'm looking at 2.7 miles per kilowatt hour on the highway at 60mph for 11 miles. Earlier around town I got 1.9 miles per kilowatt hour after 4 miles with heat on at 72f. I was hoping for 2.7 with heat on. I'm way below that. What is everyone else getting?
I'm getting better miles/kwh in winter as I don't run the AC too often.. Well, I'm in Florida, so I doubt that I'll ever need to use my heater unless I travel north..
I've been getting around 2.8 in the morning on my 50 mile (mostly highway, 75 MPH) commute when it's below 25F. When it goes over 35F, it's closer to 3.3. And last week we had a warm day at 50F and it was back to 4.2. Huge effect of temperature on range. I do have different tires (Michelin Primacy Tour), so I'm sure that contributes some too. It is very disappointing to see 185 miles of range at 100% charge though... Looking forward to spring!
