Does the 2026 Land Rover Defender have auto start-stop?

Yes. The EPA lists automatic engine start-stop on every 2026 Land Rover Defender 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.
  • The 3.0L 6-cylinder turbo hybrid mild hybrid and 4.4L 8-cylinder turbo hybrid mild hybrid are a mild hybrid, with a separate higher-voltage battery besides the 12V one.
  • Most systems have an off button that disables start-stop until the engine is next started; some models remember the setting.
