We have the 2.0d x drive 2 series Gran Coupe and it is always driven in comfort mode. On an 11 hour trip to the Isle of Skye it averaged over 50 mpg. Eco pro I find a little distracting as the tendency is to try and stop the display turning grey but to me it just removes the whole point of driving a BMW in the first place. With 4 children I am not a fast driver but love the safety of quick overtakes and being able to pull out of junctions and get up to speed quickly.
