Yes, the higher performance model will often have a higher drag coefficient, as the fenders are flared, there are scoops and intakes directing air different places, it has wider tires than the base model, etc. Your M3, for example, has a higher drag coefficient than a 320 (0.34 vs. 0.26). In fact, at 0.34 your M3 has a higher drag coefficient than the X3 M40i. So the X3 M40 is pretty low, it just happens that the X3 30i is extremely low.
