Does the 2026 Mercedes-Benz GLC have auto start-stop?
Yes. The EPA lists automatic engine start-stop on every 2026 Mercedes-Benz GLC 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 2.0L 4-cylinder turbo hybrid mild hybrid is 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.
