Remember this is the engine that obama bin laden wants you to have not what BMW wants you have. I noticed that the mpg numbers did not change much on the 5 series for 2012 when they put the little Obama 4 popper in it.
It will be interesting to see how that little thing will be holding up after 50,000 miles lugging the big heavy 5 around. My guess it will not be in too good of shape.
