What Is a Beam Wing in F1?

A beam wing is a small aerodynamic wing mounted low at the rear of a Formula 1 car, positioned between the diffuser and the main rear wing. Despite its modest size, it plays an important role in managing airflow exiting from underneath the car and contributes to rear downforce. Teams adjust the size and angle of the beam wing depending on the circuit’s demands. It is sometimes removed entirely at low-downforce circuits like Monza.

Example: Red Bull have removed the beam wing entirely this weekend in pursuit of maximum straight-line speed.
