Rear Diffuser For BMW 550i 11-16 Sedan With M Sport Bumper F10 Sedan Matte Black. Note: For F10 Sedan 550i models only. The rear end of a car underbody is where a diffuser is usually located. It accelerates the velocity of the airflow underneath the car to create downforce. The pressure under the car is affected by the diffuser so that it can expand back to ambient in the diffuser, as the car moves forward, such that the pressure decreases while the velocity increases. Since the pressure below the car is lower than on the side and above the car, downforce is produced if implemented correctly. The diffuser “drives” the underbody, which produces the downforce.
