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.

Sorry, that's not correct.

From the Car Configurator:

520d EfficientDynamics Cd = 0.27
520d, 530d, 535d Cd = 0.28
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.
