Overview

• Red Bull introduced modified floor fences and edges on Verstappen's RB21 in Miami, marking the second phase of its three-step development plan.
• The new floor aims to enhance downforce and cornering balance while maintaining aerodynamic stability, according to Red Bull's chief engineer Paul Monaghan.
• Only Max Verstappen is running the updated floor in Miami, with Yuki Tsunoda set to receive the upgrade at Imola later this month.
• Data suggests the update reduces understeer as intended, but Red Bull's decision to use a worn power unit limits top-end speed compared to rivals like Mercedes, who deployed a fresh engine for Miami.
• The final phase of Red Bull's aerodynamic upgrades is scheduled for the Emilia Romagna Grand Prix, as the team seeks consistent performance gains across diverse circuits.
