Several Formula 1 teams have modified their rear wings with additional winglets for the Monaco Grand Prix after straight mode was removed this weekend.
The change allowed teams to replace the rear wing actuator housing with downforce-generating devices inside the FIA-defined legality box. Mercedes adopted the most radical design, mounting a series of cascading winglets on the mainplane pylon along with additional elements and Gurney flaps. Red Bull fitted two enclosed winglets, while McLaren stacked longer-chord winglets on the mainplane ahead of smaller ones on the upper flap. Audi and Cadillac added cascading elements on the upper rear wing plane, and Racing Bulls extended the central chord with a single tab and Gurney flap. These additions increase downforce at low cornering speeds without creating a meaningful drag penalty on Monaco's short straights.
