DS 3 fuel economy questions
Why is the DS 3 real MPG lower than the official figure?
Official figures come from a laboratory test cycle, not the road. Cold starts, short trips, hills, load, tyres and driving style all cost fuel the test does not see. A gap of 10 to 30 per cent is normal; a much bigger gap on one engine usually points at a fault, a heavy right foot, or a diesel that never gets warm.
Where did the Honest John DS 3 Real MPG page go?
Honest John closed in August 2026 and its Real MPG section went with it. This page is where the DS 3 figures now live: rebuilt from the archived Honest John dataset, with the official figures kept alongside, and reopened for new submissions.

Where the DS 3 figures come from
If you used the Honest John Real MPG section before the site closed in 2026, this is where the DS 3 figures now live. The owner-reported averages above were rebuilt from the archived Honest John dataset (archived page, 2025-07) alongside the official NEDC and WLTP figures and new submissions from CarAdCheck readers, and the section is open so they keep improving. Real-world figures also feed the running-cost estimate in our free advert check.
