Picked up my Q5 and set off on a 1900 mile holiday to France the next day. Have to say very impressed with the economy. Generally i am getting over 40mpg, but I don't do much town driving. The best I?ve had so far is 45.5mpg on a 241mile trip back to the port in France, on our way home. Very much keeping to the speed limits and cruising at 70 - 75 mph with perhaps the odd overtake at 80 ish. I find the Q5 is a car you tend to drive a little slower and I don't have a problem with that at all and it makes a big improvement on the economy. I think there is about 5 - 6 mpg to be saved by cruising at 75 instead of 85 and you don't run the risk of points on your licence - I have 6 already.
