Which feature of electric vehicles reduces brake wear particles?

  • A.Regenerative braking doing most of the deceleration
  • B.Lighter weight, which reduces the energy the brakes must dissipate during each stop the vehicle makes
  • C.Nothing
  • D.Recovery of the braking energy by the motor, so the friction brakes are used only for the final stop and emergencies

Answer: A

Regeneration means the friction brakes do very little work. The last option explains exactly that, which makes it a correct and more detailed version. The greater mass works against them for tyre wear. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. A single measurement chosen to respond to the one asymmetry beats several that respond to shared behaviour.
