Ferrari brings its fourth significant aerodynamic package of the 2026 season to the United States Grand Prix, focusing on floor and sidepod revisions. Engineers aim to increase downforce and widen the operating window of the SF-26 to address performance issues identified at Zandvoort.
FIA technical delegates plan to reduce floor support dimensions from 20mm to 5mm to prevent teams from using structural cables to create sharper sidepod edges. This regulation change targets a design used by Red Bull and Audi to bypass standard radius requirements.
FIA laser distance sensors ensure F1 car planks do not fall below the 9mm thickness limit to prevent illegal aerodynamic advantages. This inspection process is critical at high-speed tracks like Monza where low-downforce setups increase the risk of floor contact.
Ferrari's high-rake philosophy and flexible suspension provide superior floor stability on bumpy tracks like COTA. While Mercedes focuses on sidepod airflow conditioning, Ferrari utilizes a high-temperature engine to reduce cooling mass and improve aerodynamic efficiency.
Max Verstappen faced significant bottoming issues with the RB21 at COTA due to aggressive rear axle ride height. Red Bull engineers resolved the stability struggle by raising the car, allowing Verstappen to secure pole position in the Sprint qualifying.
FIA regulations mandate a 1mm wear margin for underfloor skid blocks to control ride height. McLaren drivers Lando Norris and Oscar Piastri faced disqualification in Las Vegas after their planks exceeded these strict physical limits.
Ferrari utilizes a leading edge tower and three lateral vanes on the SF-26 to mitigate in-wash from floor boards. This aerodynamic setup manages boundary layer separation and protects underfloor efficiency to maintain downforce under 2026 regulations.
The floor is the most powerful aerodynamic device on the car. Here is how venturi tunnels work.
