Averaging a tick over 15mpg city. Has been as low as 11mpg. Blended city/highway is averaging around 19 to 20. I ususally have the car in the more aggressive sport settings also.

Now, took a over the road vacation after I got my 1200 mile service done. Total roundtrip mileage was around 2400 miles. During that trip, I average 26.8 mpg. That was with all settings in Efficient and Comfort for the most of the highway trip. Honestly I thought that was more than acceptable on the MPG front for this car. Oh yeah, that was on the winter tires and wheel setup. So not sure if the 20" summer tires would have made any difference.
