Just purchased a new (2010 with 1000 miles) S60 and am wondering what I can realisticially expect in terms of fuel economy?

 

Mine is a 2007 with over 100k miles...as long as I keep the tires filled and the wheel wells free of junk (I live in a rural area with some dirt roads, so mud can cake up in there and reduce fuel economy) I tend to get around 25 MPG. Sometimes 22 in the winter when most of my driving is on slush.

 

We own a 2008 2.5T with 60k and we average 25-27 mpg, but this car will get 32+ at a constant 65 mph highway. We have been very pleased. Also, we run 89 octane.
