The first F1 pre-season test at the Bahrain International Circuit revealed some novel rear wing solutions to active aerodynamics. RacingNews365 technical analyst Paolo Filisetti explains why.
During the first official F1 pre-season test in Bahrain, it was evident that teams are implementing three distinct pivot placements for the movable flaps of the rear wing, as they embrace active aerodynamics in the absence of DRS for the 2026 season. Red Bull opts for the pivot at the trailing edge of the upper flap, Audi chooses the midway position between the mainplane and upper flap, and Alpine places the pivot in line with the leading edge of the mainplane. Each pivot location has specific design and packaging considerations influenced by aerodynamic and mechanical parameters, impacting drag reduction and flap actuation speed. The strategic placement of the pivot also affects aerodynamic outcomes like stall potential and diffuser influence, with variations between low-mounted, central, and high pivot configurations. The technical nuances and performance trade-offs of choosing a pivot location underscore the meticulous approach teams undertake in optimizing their active aerodynamics systems for competitive advantage in Formula 1.
