Doesn’t fuel efficiency go down, though? I’d say that’s roughly equivalent to the battery losing effectiveness. And generally requires fixing or outright replacing key components to get back to par.
True, the scale isn’t quite the same, but the technology is also much newer. You’d agree that fuel efficiency, much like battery efficiency, does go down, though?
To a certain extent yes. Cams get worn down, coils make less spark, that sort of thing.
But as you said, the scale is way different. It’s the difference between a million miles and a hundred thousand. And at a million miles, even the chassis itself starts to become a maintenance item.
