Hi Nick, even if you have a very heavy right foot 250 mile's is easily achievable I would have thought. I personally don't intend using the paddles or the sport mode there's plenty for me in Auto,early days I know can't see me getting less than 35mpg.The same mileage I used to get in the plus4 duratec. What i have noticed is there is a lot more air being sucked in the back of the car around the neck area when your marching on a bit. What we all tend to forget of course we will get slightly more with the hood up, but that ain't never going to happen....
