Bargeboard :

Barge boards are an aerodynamic feature between the front wheels and the side pod on open-wheel cars.

This vertical structure is designed to redirect the turbulent or “dirty” air in the wake of the front wing, the front suspension links, and the rotating front wheels.

The change in regulations and shift to ground-effect cars for the 2022 season means the barge board is no longer required on an F1 car.
