Red Bull arrive at the Mexico City Grand Prix with a revised RB21 floor, seeking gains against McLaren. The upgrade fails to deliver, exposing setup sensitivities at altitude.
The floor is a reworked module first seen at Monza, adapted for the Autódromo Hermanos Rodríguez. It reflects an incremental path, not a clean-sheet solution.
Trackside chief Paul Monaghan labels it a “make-from,” underlining repurposed components to control cost and time. The approach aligns with focus on 2025, as others eye 2026 earlier.

Mexico City’s thin air cuts downforce and drag, stressing brake cooling and platform control. The bumpy surface further complicates aero consistency and ride height targets.
Red Bull also adjust minor aero details to tune efficiency and load. Correlation looks reasonable, but lap-time return falls short of projections across stints.
McLaren set the competitive reference again, with Lando Norris converting a tidy qualifying and strong race pace. Red Bull do not consistently reach their operating window.
Max Verstappen searches for stability and traction, but peak grip proves elusive. Sergio Pérez, despite circuit familiarity, cannot sustain pace with the front group.
The outcome underlines the risk of late-season, small-step updates when rivals prioritize reliability and predictability. McLaren’s conservative path yields steady, bankable improvements.

Strategically, Red Bull must balance short-term results with 2025 development. Wind tunnel and CFD limits make every iteration choice more consequential.
The team now faces a correlation review to understand losses in low-density conditions. Upcoming circuits should offer cleaner reads on platform and ride control.
