F15 X5 Real World MPG

[Engrik]

I have an F15 40d (on a 15 plate), I'm getting 33mpg doing relatively short trips in a very hilly environment. Few weeks back did an 800 mile trip, largely motorway, cruise at 70 much of the time, and in eco mode - that gave me 37mpg. Hope that's useful. P.S., used to have a 2009 x5 3.0d, that averaged 22mpg doing the same short, hilly trips. So, besides being around 50% better on fuel, the F15 is a MUCH better car in every respect. (Smoothness, quietness, power, mpg, comfort - everything)
