People who know about electric vehicles know that aging is different with electrons. Fewer moving parts mean fewer odometer-related mechanical failures. EV drivers also know that battery degradation tends to be slower and gentler than people fear.

So far, the news about high mileage EVs – those with more than 175,000 miles – is pretty good. But, because the majority of EVs on the road are newer, and have far fewer miles, the story is still developing.

We took a look at the top 100 odometer vehicles in our community. Excluding cars that have reported battery replacements (or those we suspect did), the average range score of these vehicles is 86.6.

This means that, on average, these cars still get 86-87% of their range when new.
