It can be good and bad. Kick it's head it all day every day and you are talking mid to low teens, drive it ok and it's the same in the twenties and on the motorway you can be up to about 32mpg.

I did a 350 mile round trip to Blackpool in mine and averaged 27mpg with all types of driving and I wasn't much below 80mph on the motorways.
