The first response is a great one.
I have driven a Tesla Model S60 for over two years now. If you start your drive with a frozen battery the 208 mile range will be reduced because the car warms the battery up to improve performance and increase the range as compared to a cold battery. If you can warm the battery while the car is plugged in you will not see much change in range in temps over 10 degree F. That can be done using the phone APP buy starting the charging process and/or turning on the heat an hour ahead of time. In temps below 10 degrees I think the heat pump used to keep things warm becomes inefficiant and a resistive heat system turns on. That's menas you will loss more range.
After driving the first 10 miles or so in cold weather typically the pwoer draw will reduce because things are warmed up. That will be your initial range loss. After that things should not be too bad unless the temps are in the single digits. So when starting off with a Model S range appears to be reduced a lot more than it will be.
In Spring, Summer and Fall I drive an averave watt/mile of under 310. (a/c or heat on)
In winter I have an average watt/mile of 339.
My S60 has a 60,000kWh battery. I charge it to 90% so I drive off with 54,000 watts/hour to use.
The math from this point is easy.
In Spring, Summer and Fall I can comfortabley drive 174 miles.
In winter I can comfortabley drive 159 miles.
If you need mor range get the S85D.
Driving slower than I do and not... putting your foot down will also improve watt/mile dramaticaly.
I have managed 218 watt/mile before on local state highways with speeds between 45-60mph, level ground. That's by far my best and rare.
I can realistically get 240-280 watt/mile by driving carefully.
