Does the 2017 Ford Focus have auto start-stop?

On some configurations. Yes on the 2.3L 4-cylinder turbo. No on the 2.0L 4-cylinder and 2.0L 4-cylinder turbo. The 1.0L 3-cylinder turbo is listed both with and without it, depending on the build.

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.
