Driver definitely plays a large part in the mpg equation, up to 30% variation according to studies.

As already mentioned the old 56mph figure has nothing to do with the current test regime.

The key problem with the quest for more economical figures in the official test, even economy minded drivers, using all the best techniques cannot achieve the good averages we once could, when there was slack in the system. We'll still get good figures but not the same percentage improvement over official, compared to a few years back.

As a general point mpg shortfall (as an average) is climbing, the more the official figures impress, the worse shortfall is getting. The 'eco' models are even worse for shortfall, than the average models. Hence why there are so many users seeing the figures as a complete farce.
