I have had my SD for just on 2500 miles now and the average fuel consumption has been 56mpg. The variation (5 fill-ups) has been from 55 to 57.5.
There has been a small improvement over time, ie some small running-in benefit of around 1.5mpg. The car has seen a mix of A road and Motorway driving, but no real city driving. My 15 mile drive to work has only a single set of traffic lights and seldom any traffic, at the time I am on the road
By the way that is real mpg. The OBC is showing 61mpg for the last 1000 miles, about 4 mpg too high.
