Does the 2020 Koenigsegg Regera have auto start-stop?

No. The EPA lists no automatic engine start-stop on the 2020 Koenigsegg Regera.

Key takeaways

  • Without start-stop, most cars take a standard flooded battery unless the manufacturer fitted AGM.
  • Most systems have an off button that disables start-stop until the engine is next started; some models remember the setting.
