Why the Floor Stay Trick Will Be Banned in 2027
Highlights
- Red Bull and Audi exploited “floor stay” loophole in 2024 F1 season
- Loophole allowed sharper sidepod shapes improving aerodynamic airflow
- FIA will ban this floor stay method in 2027 regulations
- New rules close loophole limiting radius on sidepod edges
- Change forces teams to find new aerodynamic solutions
- Loophole ban illustrates ongoing regulation and innovation battle
The FIA will ban a sidepod-related “floor stay” loophole from the 2027 regulations, removing an aerodynamic trick exploited by Red Bull and Audi during the 2024 season.
The device enabled sharper sidepod edges and a deeper undercut, cleaning the airflow towards the car’s rear and improving overall efficiency without breaching the written rules.
FIA targets floor-edge tricks for 2027, closing a route to sharper sidepod geometries and cleaner underfloor flow.
Current rules cap the allowable radius on bodywork corners to control shapes for safety and competitive equity. The loophole hinged on how the floor’s edge was supported near the sidepod.
By managing the interface between the floor and sidepod, teams shaped the flow under the flank more aggressively. The result was less drag in yaw and stronger underbody load.
Sharper sidepod undercuts improved rear airflow management, aiding downforce and straightline efficiency.
Crucially, the approach observed the letter of the radius rules, even if it sidestepped their intent. The unusual floor stay configuration made the geometry feasible and robust.
From 2027, the FIA will explicitly outlaw any solutions that use floor edges to bypass sidepod corner radius limits. That closes the avenue and clarifies enforcement.
The change should narrow design freedom around the undercut, likely prompting either convergence or fresh concepts in cooling layouts, inlet positioning, and floor edge treatments.
Rule clarity should reduce grey areas but will redirect development to other aerodynamic battlegrounds.
Red Bull and Audi continue to capitalise this season, with trackside data reflecting the efficiency gains where underbody performance dominates.
Rival teams will scrutinise the detail, especially given FIA’s clampdown on the sidepod trick arrives for 2027, demanding re-optimised sidepod and floor interfaces.
For Audi, the picture sits within Audi’s works programme and power unit build-up, alongside focus on addressing a potential engine flaw highlighted earlier this month.
At Red Bull, aerodynamic refinement intersects with Red Bull’s in-house power unit push, making 2027’s chassis reset a key integration challenge.
Closing the loophole underscores F1’s cycle of innovation and regulation. Teams probe for gains; the rulebook follows to maintain clarity, safety, and a balanced competitive landscape.
Visual Summary
🚪 Loophole!
2027 BAN
💨
Red Bull & Audi’s secret “floor stay” trick unlocked ultra-aggressive sidepods, boosting their speed.
🚗
By shaping floor edges, they channeled cleaner airflow for stronger downforce & quicker laps.
🛑
Now, the FIA has locked this loophole for 2027. The game of innovation vs. regulation rolls on.
Bottom line:
The “floor stay” sidepod loophole gave Red Bull and Audi a crucial edge— but in 2027, it’s officially locked out.
