Took my first hwy trip today of 380 miles and I got 30.9 mpg which is pretty damn impressive considering I was driving 75-80 the entire way. Up to this point I had been disappointed in mostly city driving getting 21 mpg but maybe it just needed a good break in run. Just for comparison our 2007 X3 use to get 22 to 22.5 mpg on the hwy. it's making you can drive 75 and barely break 2000 rpm.
