528i, 535i Cd = 0.29
550i Cd = 0.30
So it is a Petrol vs Diesel difference. Possibly due to a different and more aerodynamic engine undertray.
Which configurator are you using? I'm using BMW UK, and ALL the engines I quoted are the same drag factor on that site. I've just double checked what I was reading last evening and I confirm the models are listed as the same.
520d, 530d, 535d and 535i F11 M-sport Tourings. So NOT a petrol vs. diesel factor in this instance.
