A 2019 Tesla Model 3 hit 380,000 miles on its original battery pack. Range took a serious hit, the kind most owners would call alarming. Even so, it still cleared triple-digit highway miles in real-world testing. Electric vehicles have plenty of advantages over combustion cars but all of them have an uncomfortable truth sitting under the sheet metal. Engines wear out over time, but the size of their gas tank doesn’t shrink. EVs will suffer battery and range degradation no matter what. The only question is how bad it’ll get before the battery fails. One seven-year-old Tesla still running on its original battery is providing some insight. At over 380,000 miles (610,000 km), one Tesla Model 3 owned by the YouTube channel Drive Protected is going strong long after most vehicles (combustion or EV) are long dead. When new, it offered 240 miles of range. Today, a full charge shows 158 miles. That’s an 82-mile drop, or about 34.2 percent gone. There’s really no sugarcoating it. That’s substantial degradation and puts the battery well below 70 percent of its original capacity.

The car was put through a real-world highway test at a steady 68 mph, returning 138.3 miles before hitting zero. That’s not impressive on paper, but it’s far from unusable. For shorter commutes or city duty, it’s still very much a functioning vehicle. The numbers back that up. Over the test, it consumed 32.4 kWh. That’s well below the roughly 49 kWh it would have had when new. That aligns with the reduced range estimate and confirms the degradation isn’t just theoretical. Still, despite losing over a third of its capacity, nothing else about the car appears fundamentally broken. No catastrophic failure, no sudden shutdowns. It’s just a steady erosion of range over time, and about double the miles of most cars when they head to the scrap yard. In a way, this car is making a case for and against EVs. Yes, battery degradation is real, measurable, and significant. Making batteries cheaper and easier to replace in the near future is key to EV sustainability and longevity. But it also shows that even after mileage that would retire most vehicles, an EV can keep going, albeit with a shorter range.
