Red Bull’s Revised Formula 1 Floor Design for Miami Grand Prix

Get ready for an exciting weekend at the Miami Grand Prix as Red Bull unveils a revamped floor design aimed at closing the performance gap with McLaren. Despite the RB21 showing promising signs of competitiveness in the opening five rounds, its handling characteristics and tire degradation issues have been a concern.

Detailed Changes to Enhance Performance and Stability

In an attempt to improve baseline performance, Red Bull has made several intricate modifications to the underbody of their 2025 F1 car. The team has repositioned the fences inside the floor’s opening, aiming to “extract a small increase in load for the same flow stability.” Furthermore, the floor edge wing now boasts greater camber (wing curvature) to maximize downforce in this area.

Meanwhile, neither McLaren nor Ferrari have registered any changes for Miami. Ferrari introduced a new floor at the Middle Eastern races, while ‘s diffuser modifications were only seen during practice sessions at Jeddah.

Downforce Optimization and Top Speed Improvements

Mercedes has brought a new rear wing assembly to Miami, featuring a lower-camber upper rear wing flap to reduce downforce (and hence drag) in an effort to enhance the W16’s top speed along the DRS zones. Aston Martin has also introduced a new wing package addressing both the front and rear of the car, featuring a less aggressive front wing profile to balance the changes made to the rear wing.

The long straights between Turn 8 and Turn 11, as well as those between Turns 16 and 17, necessitate teams to minimize downforce to maximize top speed. As such, Aston Martin has also introduced a new wing package to address both the front and rear of the car.

Other Notable Upgrades for Miami Grand Prix

Williams has a shorter-chord beam wing to cut drag out of this weekend’s package. Alpine has prepared new front brake ducts and front suspension members to improve flow in these areas and increase brake cooling efficiency, but will not run them this weekend due to the nature of the sprint weekend. Sauber has modified its lower front suspension wishbone fairings to aid in their ongoing aerodynamic improvements.
