I am slated to take delivery next week (Model X Plaid, White, 20 in. wheels in Chicago). I currently have a 2016 Model S and have a couple of questions. Does anyone have experience with both that can speak to range, especially during cold weather? I have found that I lose 30-40% of my range in the cold, but have heard the new versions are more efficient. Are you getting close to the rated range? Also, what is your rate of supercharging? I've always felt like my Model S charges much slower than the rates I hear from people with Model 3's and Y's.
