The FIA will ban Red Bull’s sidepod interpretation for 2027, closing a loophole used to boost performance this season.

The RB22 deployed a floor body stay acting like a structural cable along the sidepod’s lower edge, sharpening the undercut.

Sidepod edges require smooth radii, but a 20mm allowance around the stay existed. Red Bull used it to energize floor airflow, first appearing in Austria.

Rivals, including Audi, introduced similar geometry during the season, validating the concept’s effectiveness.

Technical analyst Craig Scarborough dissected the approach at Silverstone, outlining why it complied with 2026 wording.

The FIA now deems the interpretation unacceptable for 2027 to align design intent with the regulations.

Reports indicate the allowable floor body stay diameter will drop to 5mm, preventing robust cable-style structures.

Red Bull and adopters must rework sidepods before pre-season testing, reconsidering structure, cooling, and flow conditioning.

This follows F1’s familiar pattern: innovation, advantage, and subsequent clarification to safeguard competitive equity.

The FIA’s broader stance, from technical directives to the Malaysia investigation, signals firmer oversight entering the 2027 cycle.

For Red Bull, aerodynamic tasks now dovetail with its 2027 programme, including power unit integration and a new solution for 2027.

Regulatory politics also remain influential, as seen when a Williams rule change was blocked earlier this month.

Expect reshaped sidepod profiles and alternative load paths to recover floor sealing and downforce.

The ruling narrows freedom around floor stays, increasing trade-offs and potentially reshuffling early-season competitiveness.
