What speed were you driving? Were you doing just 60mph or were u doing around 75mph on average? I understand that the above figures are tested at sustained speeds of about 75mph.

Also the above figures for the '05 model. Not sure if Ford has improved the engine for fuel economy, since then.

Sounds good. Wonder if the Which Car testers got it wrong!

Can I suggest that a very relevant factor is driving style. I've driven quite a few focuses (what's the correct plural?) recently as rental cars.

I find the petrol 1.6 to be hopeless on motorways. But I am driving in a manner where shortest journey time is my priority - not lowest fuel economy. To make progress with the 1.6 you need to wring its neck. Not pleasant - it's thrashy at high revs - it's relatively low geared - and as a consequence it chews the juice. I've never bothered to do a precise check on the fuel economy - but I would never have a 1.6 petrol for motorway use as the car is just too much like hard work if you need to make decent progress.

The diesels are my preference - just because they have more grunt and so don't have to be thrashed so hard.

But if you're driving style is more oriented towards economy rather than speed, I expect your perceptions and results would be very different.
