The official figure is what a MINI Countryman managed in a laboratory. These are the figures owners report from the road, engine by engine, for every generation we hold. Add your own at the bottom and the averages get better for the next buyer.

All figures in miles per gallon (UK). “Owners report” is the spread of individual submissions for that engine. * Measured against the WLTP figure rather than NEDC.
What does yours actually do? Read it off the trip computer over a full tank or work it out from litres and miles. No postcode, no sign-up. The more people add, the better the averages get, and this page stays free.
Owners report an average of 40.8 mpg across all MINI Countryman engines with data, about 80% of the official combined figure. The engine tables on this page give the figure for each engine and generation.
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.
Honest John closed in August 2026 and its Real MPG section went with it. This page is where the MINI Countryman figures now live: rebuilt from the archived Honest John dataset, with the official figures kept alongside, and reopened for new submissions.

If you used the Honest John Real MPG section before the site closed in 2026, this is where the MINI Countryman figures now live. The owner-reported averages above were rebuilt from the archived Honest John dataset (archived page, 2026-08) 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.
