I used to drive a truck and will not drive at 56mph in the slow lane along with all the trucks just to save fuel, it wasn’t a very enjoyable experience when I did it in a truck that had great visibility so I don’t want to do it in a car, I drive my 184DSG Alhambra around the 70 mark and have returned an average of 30mpg over 42,000 miles of mostly motorway running, it’s crap compared to their official 50+ figures but who ever expected VAG to tell the truth about the economy of their engines!
