The 2022 F1 season saw a significant change in aerodynamic regulations, bringing back ground-effect formula for the first time since 1982. The aim was to reduce the reliance on wings for downforce and instead focus on the floor and its venturi tunnels to develop downforce. This change also included the switch to 18-inch tires, bodywork around the wheels, and the removal of bargeboard devices. Despite the changes, the cars were generally only a second slower overall than in 2021. However, porpoising and bouncing emerged as problems caused by the ground effect aerodynamics, resulting in discomfort and a lack of visibility for drivers. To mitigate this, the FIA introduced an Aerodynamic Oscillation Metric (AOM) for 2022 and 2023. Teams must adhere to a set upper limit of 10 J/kg/100km, and the FIA can disqualify drivers whose cars surpass this metric. In 2023, floor changes will be implemented to keep any wild oscillations in check. Here is a 3D model of F1 2023 concept car attached (3dm & STL) for CFD analysis and 3D renderings (GLB).
