The introduction of the current ruleset in 2022 brought a seemingly prescriptive approach to developing the rear wing, with the prevailing design trend creating a curved merging of the upper element and mainplane into the rear wing endplate.
This was introduced to reduce the turbulence produced by the rear wing; fewer exposed edges offered less opportunity to produce tip vortices, which the aerodynamicists could build into the car's wake to enhance downforce generation. A larger low-pressure area behind the car, produced by the melding of the wing vortices and the diffuser exit, helped to boost the acceleration of the underbody flow and produced more downforce.
