BMW list the same figure for the F11 520d, 530d, 535d and 535i, so not a petrol vs. diesel thing as such.
Wonder how the F30 is so different with the same frontal area and panel designs. Could it be the flaps? Not a bit of trickery is it, on whether open or closed?
Need to do a bit of research on this.
