Ferrari took the most conservative component on a Formula 1 car and made it spin. The 2026 technical regulations retired DRS and introduced fully active aerodynamics: driver-selectable Z-mode for high downforce in corners and X-mode for low drag on straights. The rules define the start and end positions of the movable elements in detail, but say remarkably little about the path between them. Ferrari found the opportunity in that gap. On a conventional wing, low-drag mode means reducing flap incidence and widening the slot gap. The SF-26 flap does something far more aggressive: - The flap rotates beyond 180 degrees, flipping its aerofoil profile completely upside down - In the inverted position, the flow over the element separates and the wing effectively stalls, collapsing both downforce and induced drag - The central actuator was removed and relocated into a bulge on one endplate, leaving the centre of the wing unobstructed - Regulations permit a single actuator, so the opposite en...
