Ferrari experiments with radical SF-26 concept at Miami Grand Prix. Ferrari introduced several innovative aerodynamic updates on the SF-26 during the Miami weekend.

Ferrari surprises in Miami with an unusual aerodynamic solution

Ferrari brought a series of important upgrades to the SF-26 in Miami. Today we take a closer look at some of these solutions to better understand how the Scuderia has chosen to interpret the new Formula 1 2026 regulations. These are highly interesting concepts focused on cleaner airflow management in order to maximize the aerodynamic efficiency of the Italian car. The updates have been judged positively overall, although further analysis and optimization work will still be required following their debut at the Miami Grand Prix.

Ferrari introduces an innovative solution on the SF-26

In addition to the revisions made to the front wing endplate area, Ferrari introduced several modifications across different sections of the car in Miami. Around the bargeboard zone, as already anticipated during the Monza test sessions, the vertical deflector has now been divided into three separate sections, unlike the previous one-piece configuration.

This is a rather unusual technical choice and one that could potentially inspire other teams in the future, especially considering that most Formula 1 teams currently prefer to split these elements along the horizontal axis instead. Ferrari’s solution appears aimed at increasing the aerodynamic efficiency of the device while also improving management of the wake generated by the front tyre.

The turbulence produced by the rolling front tyre is particularly problematic under the 2026 Formula 1 regulations, as airflow now travels much closer to the bodywork. Ferrari also introduced smaller micro-aerodynamic changes to the so-called “saracinesca,” namely the three horizontal elements positioned next to the previously mentioned appendages, altering both their angle and terminal shape.

Ferrari reshapes the floor to improve turbulent airflow management

Continuing the analysis further along the floor area, a targeted intervention can be seen on the trailing edge positioned ahead of the rear wheels. As highlighted in the image, Ferrari engineers created two slots designed to channel airflow underneath the floor. This device once again plays a key role in controlling the turbulence generated by the rolling rear tyre.

The primary goal is to reduce the vortices created by the so-called tyre squirt effect, which travel parallel to the lower section of the tyre. The inset image also provides a closer look at the small appendage responsible for generating a downward vertical push, an element that helps create ground pressure useful for cleaning turbulence in that specific area.

The SF-26 takes a step back on the FTM exhaust solution

Finally, the update package also involved the FTM system. As already discussed in a recent technical analysis, it is crucial to further investigate the engineering concepts behind this particular solution. Ferrari decided to take a slight step backwards, introducing a hybrid configuration that combines the previous specification with the version originally seen during pre-season testing in Bahrain.

The appendage is now divided into three separate segments: a central section directly exposed to the airflow and two lateral fins positioned alongside the exhaust outlet. Although the side elements do not interact directly with the exhaust gases — and therefore generate less vertical thrust — they still remain important for producing rear-end downforce on the Ferrari SF-26.

Compared to the previous version, the surface area exposed to the exhaust gases has been reduced, likely accompanied by a lower incidence angle of the appendage itself. This theory is supported by the thinner support structure now visible on the component. Thermal analysis work is also continuing in parallel, as demonstrated by the sensor patches installed to monitor the operating temperatures of these parts.

Looking closely at the same image, additional vertical deflectors can also be seen beneath the lateral appendages. These elements help further increase aerodynamic load while improving airflow extraction from underneath the floor. Part of the suspension arm is also visible, specifically profiled to generate an upwash effect on the airflow.

The technical evolution of the Ferrari SF-26 in Miami highlights the Scuderia’s commitment to mastering the complex “micro-aerodynamics” of the 2026 era. By splitting the bargeboard deflectors vertically—an unusual move compared to the rest of the grid—Ferrari is seeking to reclaim control over the sensitive front-tire wake that dictates overall car balance. While the hybrid approach to the FTM exhaust suggests Maranello is still fine-tuning the balance between thermal thrust and pure downforce, these updates represent a clear design philosophy focused on precision and flow stability. As the 2026 championship intensifies, the success of these innovative slots and vanes in mitigating “tyre-squirt” will be the deciding factor in whether Ferrari can gain a competitive edge on high-speed circuits.
