McLaren Adopts Monaco Rear Wing Concept Alongside Mercedes and Red Bull

McLaren has introduced a rear wing fitted with extra winglets for the Monaco Grand Prix, joining Mercedes and Red Bull in chasing maximum downforce without active aero. The change leads a six-part package for the MCL40, targeting both performance and reliability at Formula 1's slowest venue.

Why it matters:

Monaco's tight layout demands relentless mechanical grip and aerodynamic load. With active aero deactivated and rear wings fixed in place, teams must recover downforce through static elements alone. The convergence of McLaren, Mercedes, and Red Bull on comparable winglet solutions highlights the narrow engineering window that defines Monte Carlo.

The details:

• McLaren's winglet cascade and a new front suspension are Monaco-specific items within a six-part package that also includes a larger engine cover, revised beam wing, and rear corner tweaks.
• The added winglets compensate for the fixed-wing configuration, recovering grip normally generated by active elements.
• Mercedes added small winglets within its rear wing fairing, while Red Bull extended the SM fairing with a central extension.
• A new floor stay attached to the diffuser addresses reliability by improving robustness and deflection control.
• Ferrari has brought a new front suspension, floor, and diffuser, while Alpine and Racing Bulls added rear wing tweaks of their own.

The big picture:

Monaco remains a calendar outlier, but the development push shows no team can afford to treat it lightly. For McLaren, extracting every fraction of performance at a circuit where qualifying is king is essential to defending championship momentum. Though these parts are circuit-specific, the lessons on low-speed balance often influence broader seasonal upgrades.
