Bargeboard

A bargeboard is an aerodynamic panel positioned on either side of a racing car between the front wheels and sidepods, designed to manage airflow around the vehicle.

Bargeboards redirect turbulent air coming from the front wing and wheels, improving the car's overall aerodynamic efficiency. By controlling this airflow, they help generate downforce (which increases grip) and reduce drag, making the car faster and more stable through corners.

First introduced by McLaren in 1993, bargeboards became increasingly complex in Formula 1, evolving from simple panels to intricate multi-element structures. They were standard on F1 cars until 2022, when regulation changes eliminated them to simplify aerodynamics and promote closer racing.
