BMW 7 Series fuel economy questions
Why is the BMW 7 Series 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 BMW 7 Series Real MPG page go?
The site closed in August 2026 and its Real MPG section went with it. This page is where the BMW 7 Series figures now live: rebuilt from the archived dataset, with the official figures kept alongside, and reopened for new submissions.

Where the BMW 7 Series figures come from
If you used the Honest John Real MPG section before the site closed in 2026, this is where the BMW 7 Series figures now live. The owner-reported averages above were rebuilt from the archived dataset (archived page, 2026-06) 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.
