Cars covered in flo-vis paint are one of the most distinctive sights of Formula 1 testing. But what are teams actually learn from this colourful and messy-looking tool?
During pre-season Formula 1 testing, teams use flo-vis paint to visualize airflow around their cars by starting with aero rakes and then covering the cars in flo-vis paint to analyze body surface airflow. In 2024, Williams used an excessive amount of flo-vis paint on their front wing to understand the attachment of the front wing underside airflow, though it may have been too thick for detailed analysis. The goal was to track the front wing wake and its impact on the sidepods. Detailed analysis involves extending flo-vis lines to identify airflow sources and potential issues like radiator duct spillage affecting airflow through the sidepod undercut. Observations are made on airflow from the wheel, chassis, and nose, providing valuable insights for teams to refine their aerodynamic setups based on data collected during testing sessions.
