The range goes down in cold weather, both because batteries deliver less power when cold, and because energy for heating the interior comes from the batteries rather than being a free byproduct of engine operation.
The batteries are a large percentage of the total cost. Tesla is evasive about the cost of replacement batteries. You WILL need replacement batteries eventually.
Bottom line: The Tesla S is a very expensive toy right now.
What I said.
And I really am confident the S Model was not created for Iowa, or deep rural areas with ever changing extreme weather.
Probably the same reason why ya don't see too many Porsche's in Minnesota or rural Ohio...Especially in winter.
Just a wild guess, but I'd say most people purchasing the S Model, will not be located in snow and ice country.
This is not an Oldsmobile nor will it be mass produced like an a typical SUV.
Once again, people who live in snow and ice country would be much better off with a typical SUV.
