I searched and found a few other threads on this, but thought I would ask my question with a fresh one given it may be unique to the seasons changing and that "Winter is Coming...". My 90D w/ 20" wheels gets a 90% charge of about 232-233 miles of rated range (i.e what the battery icon shows when it's charged to 90%). However, it seems that unless I drive 45mph or less without much stopping and going, there is no way I would get that type of range in reality. That's okay since I know even EPA estimates of MPG are not always reality and only in the best of driving conditions. I've had my X since August, and the rated range hasn't changed all that much, but it seems recently and with the weather getting colder, my "real range" is dropping dramatically. For example, yesterday after charging overnight to 90%, I did about 110 miles of driving (half highway, half local), and came home with about 75 miles of remaining range. Doing the math, that would give me about 185 total miles, well off of what the 232 rated range is. I recognize that the rated range is really under perfect driving conditions and/or will be better if I was doing a steady 55-65mph on highways. However, 185 or probably much less (reality may have been about 150-160 total miles yesterday) seems to be a lot less than the rated range and that I would expect. When I bought the X, I expected a reality range of at least 200 miles of driving under similar conditions...didn't think I would lose 1/3 of my range to using the vehicle's heating/cooling and road/weather conditions. I don't think I have a lead foot and rarely slam on the accelerator... My question is, were my expectations off or is this just the nature of electric cars and doing a mix of local/highway driving along with the polar vortex...?
