DS 3 fuel economy questions

What is the real-world MPG of a DS 3?

Owners report an average of 52.0 mpg across all DS 3 engines with data, about 81% of the official combined figure. The engine tables on this page give the figure for each engine and generation.

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?

The site 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 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 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.
