With one-fifth the number of powertrain parts and an almost total elimination of oil (a), the typical automotive dealer will suffer 35% declines in maintenance and service revenue, or roughly $1,300, for an EV versus an internal combustion engine vehicle over a five-year period (b).
But this disruption is not even. Two of the top three maintenance items — oil changes and brake service (24% and 5%, respectively, of all maintenance transactions in the U.S. market) — are reduced or eliminated entirely by the move to EVs (c).
Why are brakes impacted? EVs often use a process called regenerative braking, which slows vehicles down while also saving energy. The reduced wear on pads and rotors is striking: some Toyota Priuses are still operating on their first set of brake pads after more than 100,000 miles of use, whereas you’d normally assume pads would be replaced after about 30,000 miles.
