Every car, ICE or electric has its peculiar features and the Model S is no exception. Here are some features I have found as applied to winter driving. Maybe others can add their experiences: 1) Snow or ice accumulation on a parking assist sensor will result in a drivers notification that park assist is disabled. That is ok and not unexpected. However, each time the car slows to less than 5mph, an alert chime is given to stop to avoid a collision, even if all is clear. Ignore it or get out of the car and wipe off the sensors. 2) In very cold conditions, maybe around zero F, the regen may be totally disabled until the battery warms. A drivers alert is given. Disabled regen will result in very free coasting which may be an unexpected driving behavior. Be careful. 3) I have found that the charge port can ice up so that it does not pop open when released. A few gentle taps seems to be enough to break the ice so the port will open. 4) If the battery starts cold, a significant amount of power will be used to heat it during the first miles. This means that energy consumption for a 20 mile trip may double from a normal 300 Wh/ mile to over 600. For a 100 mile trip the consumption in 10 degree F weather may approach 350 Wh/mile, in line with the 20% penalty others have reported. For a 3 mile trip the energy consumption may average off the chart. 5) I have found that the traction is better than a Mercedes E class I formerly had. probably due to the rear biased weight and the high pressure tires. I will not get snow tires. I love the car, it just takes some understanding to use its technology in cold conditions.
