car Cd drops after adding inlet and outlet?
 
Hi all,

When adding air inlets or outlets to a car, is it possible that the Cd would drop as a result? I have made a basic car model as shown below. After adding the inlet on the hood and outlet on the roof, the Cd drops from 0.489 to 0.443. Did i make a mistake here?
