SEAT Exeo ST fuel economy questions
Why is the SEAT Exeo ST 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 SEAT Exeo ST Real MPG page go?

This page is where the SEAT Exeo ST figures now live: rebuilt from the archived Honest John dataset, with the official figures kept alongside, and reopened for new submissions.
