I believe mine usually gets around 24 - 26 as an average of mostly round town and local area which is a max of 40mph when able to do so.
On a decent run where I managed to keep reasonably sensible for the majority it managed about 36mpg iirc but I'm well used to the fact now that my car is not going to set any records for best consumption ever especially with my usual driving style, not saying I drive like a **** there but I enjoy the car.
If I was to get anything else it'd be an older turbo which in honesty would be roughly the same figures anyway. Never going to get a normal economical car as would be far too bored.
Great figures there on the graphs, forgotten my login on the one I use so still trying to get back on to upload mine lol
