How Red Bull Masters a Design Rule with a Bold New Concept

Highlights

Red Bull debuted a unique 2026 F1 car upgrade in Miami GP
Features sharp sidepod edges exploiting a legal rule loophole
FIA approved design despite it contradicting original regulation spirit
Design boosts downforce by improving underfloor airflow sealing
Rival teams like McLaren studying Red Bull’s aerodynamic innovations
FIA may revise rules for 2027 to address design loophole

Red Bull unveils a major 2026 car update at the Miami Grand Prix, built around a novel interpretation of the bodywork rules. The FIA reviews and approves the concept.

The package spans the car, with visible steps at both ends. A prominent front-wing diveplane and an inverted-style rear wing headline the external changes, supported by extensive floor and bodywork rework.

Key to the concept is a reshaped sidepod architecture. High-walled inlets, broad “waterslides,” and a pronounced sidepod edge reshape flow paths feeding the floor and rear bodywork.

Red Bull’s sharp sidepod-to-floor edge exploits a separation between reference volumes in the rules, creating a legal feature outside usual curvature limits.

That sidepod edge forms an unusually sharp rear corner where most teams use smooth radii. The edge aligns with the floor at an unexpected angle, creating a strong, persistent vortex structure.

Ferrari and Mercedes retain smoother, downward-swept sidepods with more exposed floor. McLaren trends similarly, though its surfaces are less steep and more rounded than Red Bull’s latest form.

Andrea Stella underscores that rival teams will study the geometry closely, given its potential to reshape floor sealing and rear stability under varying ride heights and yaw. -> This line contains tags by mistake. Need fix. We must wrap with
