Today marks 4 years (!) since we picked up our 2022 Tesla Model 3 from the delivery center in Knoxville, TN.
To date, it’s been fun to drive and remarkably reliable - only one repair, under warranty, for an inoperative rear window defroster. Over 90,000 miles, maintenance has been 2 sets of tires, one alignment, 12v battery replacement as preventive maintenance, 1 cabin air filter and windshield washer fluid. And that’s it.
Only negatives? The road and wind noise are pretty loud, and the paint seems a bit “soft” and prone to blemishes.
Lots of highway miles, taking us from our E TN home north as far as Ottawa, south as far as Key West, and innumerable other trips up and down the eastern U.S. With the Supercharger network, range anxiety has been a non-issue.
But speaking of range…
How does one get from 358 miles of advertised range to 237 miles or even less of day-to-day range? None of this is meant as a complaint - to paraphrase Scotty, “You canna complain about the laws of physics!”. But still, that decrease in range needs some explanation.
First, in 2022 Tesla’s range estimates were known to be pretty optimistic. I hear they’re more realistic now.
Second, physics and battery chemistry dictate that your range will only go downhill from your very first drive. The decline is relatively rapid at first, but supposedly levels off a lot over time and miles.
Third, the chemistry in our model’s batteries dictate charging to no more than 80% in day-to-day driving.
Fourth, cold temps don’t help, and it’s been pretty chilly this winter in E TN.
Fifth, I decided on our most recent tire purchase to go with non-EV tires - Michelin CrossClimate 2’s. That was based on availability, price, a longer tread wear warranty, and better usability in snow. That alone accounted for more than a 10% range loss.
Bear in mind, when the car “guesses” a certain range, in my case roughly 237 miles at 80% charge, when actually driving the miles traveled since charge plus miles remaining virtually never equal the car’s estimate.
Our most recent battery test showed our battery still had 84% of its original capacity, which Tesla considers “An expected range based on the car’s age and mileage”. Charging to 100%, which we rarely do, now shows 300 miles of range. In any case the 80% is more than adequate for around town, and no real hardship on road trips, since we don’t mind stopping every 3 hours or so to charge. But the decrease in range has definitely eaten into the healthy battery reserves we like to maintain on trips.
Basic lesson? When EV shopping, go for range well beyond what you think you might need, especially if you plan on keeping the car for the long haul.
