Interesting. we picked our 2013 X3 28i up in mid January and have yet to break thru the 20 mpg barrier on any trip. It has been cold here in MO and we will be stuck on reforumlated gas until sometime in March. I'm hoping MPG really starts improving or I'm gonna be rethinking this purchase. My wife is the primary driver and she does not punch the vehicle like I do when I drive. She uses the start/stop feature and drives with the tranny in D. We currently have only 1800 miles on it and run 91 to 93 octane.
Looking back at the records for our previous '09 535i Sport we would at least break thru 20 MPG in the winter months. That car was a helluva lot quicker and faster than this X3.
