When this man did a health check on a 2021 Tesla Model 3 Long Range with 250,000 miles, he was stunned by what he leaned.
YouTube channel RSymons decided to take stock of the EV after it’d racked up hundreds of thousands of miles over a four year period.
When doing a test like this, you’d brace yourself for some bad news, right?
Well, let’s just say that this man was going to be left surprised by the end of his video.
The fear around high-mileage EVs
At face value, high-mileage cars can elicit impressed reactions.
Many will applaud the fact that a car has lasted for so long.
But behind that figure, issues can often lurk.
And this is often a fear many people harbor when it comes to EVs that have been around the block a lot.
Despite real-world data showing that EV batteries often outlast their cars, the fear persists that the batteries can’t handle high mileage.
Plenty of EV owners have ran the numbers on their Teslas to see how they fare after hundreds of miles, with some interesting results.
How had this Tesla Model 3 Long Range held up after 250,000 miles?
YouTube channel RSymons performed a full health check on this Tesla Model 3 Long Range.
Technically it was just sitting beneath 250,000 miles, but over the course of the video they bumped up the figure.
But regardless of the exact mileage, how had this car held up?
Initial diagnostics from Scan My Tesla found that the battery had retained 84 percent of its original capacity, which meant it offered between 285 and 300 miles of range.
That’s slightly down on the 330 promised when brand new, but it’s still a strong showing.
Even though the car had exceeded Tesla’s warranty mileage considerably, the battery degradation was negligible.
There was plenty of positives to go around – the car retained its responsiveness, and responded wonderfully at the supercharger.
When the RSymons team pulled up, it was at 16 percent and added on 30 percent within 11 minutes.
All in all, the car passed with flying colors and received a hearty endorsement from its reviewer.
“Combustion cars are kind of known for losing their horses as they get older… but I don’t think that’s a thing with electric cars. This feels as quick as the day it was new,” he said.
“I would genuinely just get in this car now and drive it across Europe… turn up and just plug it in. You don’t even have to get payment cards out.”
