Overview
- The FIA barred 2026 active‑aero straight‑mode zones for the Monaco Grand Prix, leaving actuator hardware redundant and opening a legal volume above the rear wing that teams may fill with bodywork.
- Seven teams have confirmed Monaco‑specific rear‑wing revisions in the FIA update disclosure, including Mercedes, Red Bull, McLaren, Racing Bulls, Haas, Audi and Alpine.
- Designs vary widely: Mercedes fitted an especially dense triple‑flap/array that removes the traditional actuator column, Red Bull and McLaren used simpler two‑ or three‑element cascades, and some teams removed housings entirely to cut blockage and weight.
- Paddock sources and technical analysts say the winglets give only modest gains on Monaco’s low‑speed layout—typically hundredths of a second per lap with extreme designs possibly worth up to a few tenths—so the changes are mainly one‑race, circuit‑specific optimisations.
- The episode shows how a safety decision by the FIA created a narrow regulatory opening that teams quickly exploited under the actuator‑housing dimensional rules and underscores how small aerodynamic margins remain valuable in F1 development.
