My experience with Turtle Mode: I thought Turtle Mode meant that the car would only go a short distance at 3 or 4 mph. It also means you can safely drive down to zero charge in emergencies. That’s 15% range loss over 3 years and 80,000+ miles if you want to count that way - not quite as bad. Using that figure, I calculate 264/310 =. My car went into Turtle Mode at 264 miles (after 13 more miles). I heard that the car wouldn’t be dead at zero miles but would eventually go into “Turtle Mode.” The car performed normally as I drove around the neighborhood in smaller and smaller circles. At that point, the distance since the last charge read 251 miles. Then I drove around my neighborhood in big circles until the SoC was zero miles. How did I get the state of charge down to zero and “below”? Over two days and two trips to Salt Lake City, my state of charge (SoC) on arriving home was 11 miles. If you drive at about 25 mph, your car can go hundreds of miles further than a normal mix of highway & city driving, whereas if you drive 90 mph on the Interstate, your car will go a far shorter distance than its generally estimated range. However, the next time I visit a delivery center, I will compare the EPA rating with the in-car 100% computer estimate for a new car to see how different/similar they are.Įditor’s note: Again, note that the speed at which you drive will affect your range. So, I can’t just run to a Tesla delivery center to check on a new car. New Model 3 Long Range cars have an EPA range of 358 miles. You would also need to do this test when the car is new to compare, if you want to get an accurate figure by this method. Wow! That’s a lot! The degradation would be less if you believe that Tesla’s EPA range of 310 miles for the Model 3 Long Range is unrealistically high. If we use that measure, my car has lost 19% of its range in 3 years and 80,000+ miles. If we compare that to the 310 mile EPA range of the car, we get 81% of its original rated range.

This is a measure of current range that doesn’t depend on Tesla’s algorithm - but does depend on what kind (speed) of driving you’ve been doing. When I reached 0% charge, the distance since last charge was 251 miles, with the car doing a mix of city and mostly freeway driving at 70 mph. If you go to the Trips heading on the main menu in the car, one of the results is miles since your last charge. Yesterday, I made a more real-life estimate of my current range. You don’t actually have to charge to 100%. Note: I now realize that all you have to do is set the charge limit to 100% and it will give you the range estimate. That’s 92.6% of its original range, or 7.4% battery degradation, after 3 years and more than 80,000 miles. The EPA range of our car new was 310 miles. When I checked the range at 100% charge, it gave me 287 miles (462 km).

But we have traveled to Utah to Wisconsin (and back) 3 times, to North Carolina and back once, and to Southern California and back once, so we have about 12,000 Supercharger miles logged (which are more stressful on the battery). Most of my charging is done at home on level 2 charging, which is the easiest on the battery. I’m trying to be as easy as I can on the battery. I always set the charge limit to 80% at home and only occasionally go as high as 90% on the road. I wanted to determine how much battery degradation had occurred over that time and mileage, so I recently set the charge limit to 100% - for the first time since we bought the car - to do a range test. We’ve just passed our 3 year anniversary! Our odometer as I write this reads 80,821 miles.

We were totally excited on Octowhen we drove our Tesla Model 3 Long Range away from the Tesla Salt Lake City Delivery Center.
