Consumer Reports does an MPG test around CT, driving a combined highway/local roads drive with average traffic. When I buy my cars I get close to the MPG of what they get, but usually a little higher (I also live in CT but I live in eastern CT while they are located in central CT).
I don't own this car but since you are not getting any responses I will give you what Consumer Reports got with the 2.0L turbo engine they used. They managed 24 mpg on average. EPA is 17/34 so it is about what you would expect in mixed driving on average.
I also found a site that can give you a decent idea from thousands of owners. It is:
The most people average on that site (895 owners of the Q5) is 22 mpg.
Best of luck.
