EVs have less maintenance costs than ICEs in general, but they have particularly less maintenance requirements during the for the lifespan rental companies keep their cars, often less then 30k miles. During that time you are really just looking at oil changes, fluids, and filters, which EVs don’t have or have less of.<p>Later in a car’s lifecycle you’ll start seeing things like tires, brakes (better with regenerative!), and trim start needing replacement, along with the battery. My older ICE’s most expensive maintenance issues in the last 2 years were the window regulators all failed- that has nothing to do with the power train.<p>Which is all to say EVs are cheaper to run overall, but they are suited to save even more money for rental companies than individual consumers.
