thats very low IMO for your car unless town driven all the time.
Unfortunately i've only really driven the commute so far since I picked the car up. It's littered with temporary traffic lights and in the cold mornings the start-stop hasn't been available so i've barely got to 20+mpg before it slowly drops at the traffic lights! It was only yesterday however i realised that the mpg on the trip view on the dash is the one that is since I got the car and the trip computer showing the journey mpg is on the iDrive screen! I had thought it wasn't very dynamic and that's why!
