BMW 3-Series Rear Diffusers

A diffuser is an aerodynamic device for reducing drag caused by the transition of airflow rapidly moving underneath the vehicle. For that purpose, the rear diffuser is normally accompanied by the front spoiler and side skirts, which can be either integrated into the vehicle's body or installed individually. While providing significant aerodynamic advantages, diffusers are applied all over the motorsport world. These aerodynamic parts are also installed on high-performance road cars, where they, however, most often serve styling purposes.
