As EVs began to make their way into the mainstream about 10 years ago, one big question on everyone’s mind was how these cars would hold up over time. And thanks to a new video by Out of Spec Reviews, we can get a sense of exactly that.

The video covers a 2017 Tesla Model X 100D with over 200,000 miles (321,869 km) on it, which we’d say is a sufficiently well-traveled vehicle. On top of that, the owner of the vehicle said 65 to 80 percent of his charges were at Superchargers and other fast-charging stations, which would theoretically deteriorate the battery more than standard ones.

The result of all that? Only a 9.8 percent reduction in battery capacity. When new, the car’s battery was rated at 93.7 kWh of available energy, and now, after 5 years, 200,000 miles, and plenty of hard charging, the battery still hold around 85.4 kWh.

That’s pretty impressive if you ask us. And not only that, but since the video was filmed in Germany, the owner mentioned that just before the day of filming he was able to take the Model X out on the Autobahn, and it had no trouble getting up to its top speed.

Aside from the battery and powertrain, there are a few points of wear on the car, but nothing too out of the ordinary for its age and mileage. The body is in good shape, the interior’s upholstery is only slightly wrinkled, and there’s minor surface rust around some of the areas of the car that open up. The only major issue is that the leather on the steering wheel has begun to deteriorate after such frequent use.

Overall, though, according to the owner, all the parts that wore out did so like they would on normal cars, and it was actually the unconventional powertrain that showed the best longevity.
