Does the 2023 Toyota Prius have auto start-stop?

Yes. The EPA lists automatic engine start-stop on every 2023 Toyota Prius configuration.

Key takeaways

  • Start-stop cars restart the engine many times per drive, so they are usually fitted with an AGM or EFB battery - replace like with like.
  • Most systems have an off button that disables start-stop until the engine is next started; some models remember the setting.
