I just came back from a day business trip to Montreal (return to Ottawa). I filled up last night and immediately upon my return home. Total trip km's were 429 with about 10% of total mileage in heavy stop and go traffic (Montreal core at 3:45 PM and Ottawa 417 traffic at 5:30 PM.

I had the cruise set at 120kph for almost the entire trip. On the return my odometer rolled past 12,000 km. The car calculated trip consumption at 9.4 and fuelly.com calculated 9.8. I'm really pleased with both the accuracy of the car computer and the fuelly calculated 9.8 especially given my average speed over most of the highway miles and the stop and go rush hour traffic in both Montreal and Ottawa.

I have had zero issues with my 3.2 Q sline since pick-up in Sept 2010. My first Audi and definitely not my last.....luv'n the Q.

 

That sounds right...
I get around 9.7l/100km hwy in my 3.2L Q5. (calculated by 3rd party software, not in the Q5)
