I hear all the claims about how far a Tesla can run. But lets get real. The car has to run in the real world. Some owners, in a city like Chicago, might have to use it in extreme heat or extreme cold. I was curious how much battery charge would have to be used to heat or cool the interior on a hot or cold day?

You lose a few miles of range by running A/C. My understanding is that it will take more of a hit in extreme cold (maybe 20-25%) but I have no first hand experience. My Model 3 has a 310 mile range so a bit of range loss won’t be a cause for concern.

Put one somewhere like Florida and the ac needs to be used almost year round. Turning it off to conserve power doesn’t cut it if you don’t want to soaked in sweat when you arrive at your destination.

Well, if the AC does impact range by about 20%-25%, then a fully-charged Model 3 LR should be able to travel 230+ miles with the AC running.

I do have first hand knowledge and your guesstimate is about right. I've had my Model S for almost 3.5 years. I'm in Colorado and drive to the ski areas in Summit Co. weekly in the winter.

Heat uses about 3x the energy that AC does, so you'll have no issues in Florida. I don't notice any range loss from AC because with the AC off and the windows open at highway speed it's a wash due to increased drag from open windows or sunroof. As a matter of fact, one of my favorite features this time of year is leaving the AC running (you can do that since it's electric and not dependent on an engine transferring motion from a fan belt) when I'm running errands. Come out to a nice cool car!

Same here. It's nice to be able to run the climate control in the driveway (or even the garage) without worrying about the fumes.

Isn’t that essentially the same thing as running an engine to keep the car cool as you run errands?

While a 300 mile range is great for most daily driving applications the problem starts when you are on a trip and you reach your 300 mile range and theres still 500 miles to go ,now what?

What do you do when you drive 300 miles and your car is low on gas? You stop and refill. Its just going to take a little longer with the Telsa.
