Just like all other vehicles (including internal combustion engine’d vehicles), the Tesla Model 3 is less efficient in cold weather than during warm weather.
How to combat cold weather range loss in Tesla Model 3
The largest consumer of electric battery packs is trying to heat the interior of the vehicle. Pre-heat the vehicle while plugged in whenever possible to help increase range. Note that on the Model 3, there is no way to manually engage the battery management system to preheat the battery – it will decide itself when the battery needs to be warmed and will circulate the heat generated from the motor and inverter into the battery pack.
Check your tire pressure and make sure, despite the cold weather, tires have the correct pressure.
Keep your Model 3 clear of snow and frost – anything on the surface of the vehicle affects the coefficient of drag, even dirt to some extent. However, big piles of snow or thick frost have an even greater drag.

This YouTuber didn’t preheat the cabin and the battery has been sitting all night in -6 degree celcius weather. After a 35 mile trip into the city with the heater and seat-heater on, found that range was around 275 miles.
