....and what performance/range hit are you guys getting? I've been driving the Model S the past week with the cold we've been getting in Chicago area. With a daily driver charge, I'm getting a reported 231 miles per charge HOWEVER with normal use, the range decreases considerably during use. I try to drive with the climate control off and heated seats on, until the windows fog up or I get too cold. In 68 miles of driving yesterday (after a full charge), I had an average of 89 miles left. Today, with 227 miles of range showing on the odometer after a full daily driver charge, I drove 5 miles and the parked the car showing 203 miles left. The car was preheated while still plugged in to the charger both mornings. Am I doing something wrong or is this expected? Anyone driving their cars in similar climate care to share their experiences?
