Battery degradation remains a huge concern among EV-curious customers. I hear it all the time. I love the idea of an EV, they say, but will its battery last? This is a good question, but I find almost everyone who asks it drastically overstates their commitment to their vehicle. They want to know about how the battery will fare in 250,000 miles, even if they only keep their cars for 30,000 or 60,000 miles on average. Generally, I tell them not to worry. Modern EV batteries are exceptionally reliable, and they will likely go far longer than the average internal combustion vehicle without serious issues. Yet they will degrade. A new video from Out Of Spec Motoring shows how much a 2019 Tesla Model S battery degraded after 250,000 miles, and it's more than I expected. Still, racking up that many miles in less than six years means it was likely Supercharged frequently and driven constantly. We also don't know if this car underperformed its EPA range when it was new. Either way, though, I'm hopeful about the future of EV longevity. Range slowly degrading means the car will remain useful for shorter journeys for many, many more miles. —Mack Hogan, Deputy Editor |
