Ferrari is continuing to develop the SF-26 despite the approaching end of the 2026 Formula 1 season, with its latest Austin upgrades potentially serving a much bigger purpose than improving performance in the remaining races. The aerodynamic developments could also provide valuable information for the design of the team’s 2027 car, allowing Maranello to explore concepts that may remain relevant under the next set of regulations.
The Scuderia arrives at the United States Grand Prix with a new upgrade package, raising an important question: why continue investing resources in the SF-26 when Formula 1 teams are already concentrating increasingly heavily on their next-generation cars? The answer goes beyond the pursuit of immediate lap-time improvements. By introducing new aerodynamic solutions, Ferrari can test different design approaches, validate its development tools and collect information that could influence future technical decisions.
That makes the Ferrari upgrade package planned for Austin particularly interesting. Its value may ultimately be measured not only by the performance gained during the United States Grand Prix weekend, but also by the knowledge generated for the next phase of the team’s Formula 1 development programme.
Why Ferrari is continuing to develop the SF-26
Several leading Formula 1 teams have introduced significant bodywork and sidepod modifications during the closing stages of the championship. McLaren has presented a revised solution, Mercedes has brought a substantial aerodynamic package to the circuit, and Red Bull has pursued a different approach involving specific concepts in the design of its bodywork.
Ferrari is following this development trend with its own updates for Austin. However, as the next regulatory changes approach, it would be reasonable to question whether concentrating every available resource on the following season’s car might be a better strategy.
The reality is more complicated. Although the 2027 regulations will require changes to specific areas of the cars, this does not automatically mean every aerodynamic concept developed during 2026 will become obsolete. Work carried out on the shape of the bodywork can generate knowledge that remains useful when designing a subsequent generation of Formula 1 machinery.
When engineers make substantial changes to the sidepods and surrounding bodywork surfaces, they are not simply modifying isolated components. They also alter the way airflow is directed towards the rear of the car, influencing the aerodynamic conditions around the rear wheels, above the diffuser and near the rear wing.
Understanding how to manage these airflow structures is essential because the performance of one component is closely connected to the behaviour of surrounding surfaces. A modification to the sidepods can therefore affect several aerodynamic areas simultaneously, creating opportunities to improve the overall efficiency and operating characteristics of the car.
The lessons gained from controlling these flows may provide an important foundation for future design decisions, even when changes to the regulations require individual components to be redesigned.
Ferrari’s aerodynamic upgrades are not only about increasing downforce
One of the most important considerations when examining Ferrari’s latest aerodynamic developments is that an upgrade does not necessarily aim to increase downforce in every operating condition. A revised sidepod shape, for example, can serve several different objectives depending on the weaknesses engineers are attempting to address.
Technical departments may seek additional aerodynamic load, reduced drag or greater stability as the car’s ride height and setup change. These objectives are closely connected, and achieving an improvement in one area can involve compromises elsewhere.
A Formula 1 car capable of generating substantial downforce under one specific set of conditions is not automatically the most effective when its pitch, roll or ride height changes. Engineers must therefore understand how the aerodynamic behaviour evolves across a broad range of operating conditions rather than concentrating exclusively on peak downforce figures.
This process involves constructing what is known as an aerodynamic map, which describes how the car’s aerodynamic performance changes as different parameters are adjusted.
Using computational fluid dynamics, commonly known as CFD, alongside wind tunnel testing, teams investigate variations in total downforce, the distribution of aerodynamic load between the front and rear axles, and the drag generated under different conditions.
These investigations help engineers establish whether a new component improves the overall aerodynamic efficiency of the car or makes its performance less sensitive to changes in ride height and attitude.
A modification to the sidepods might therefore produce relatively modest improvements in maximum downforce while delivering more consistent behaviour across a wider operating window. Depending on the characteristics of the existing car, that consistency can be an important objective in its own right.
For Ferrari, the knowledge obtained through these experiments could be just as valuable as the immediate performance improvements generated by the SF-26 upgrades. The broader development process also forms part of the team’s continuing work on Ferrari aerodynamics, car setup and technical performance.
Why the 2027 regulations will not make Ferrari’s 2026 development irrelevant
The 2027 Formula 1 regulations will introduce different design requirements, forcing teams to reconsider various aerodynamic elements. Particular attention will be required in areas of the floor and in the components that influence the airflow reaching those surfaces.
However, an important distinction must be made between aerodynamic solutions directly affected by regulatory changes and the broader principles used to control airflow around the bodywork.
A concept developed for the SF-26 will not necessarily be transferable to the 2027 Ferrari without modifications. The geometry, operating conditions and interactions between components may change, meaning that solutions effective on the current car could require substantial adaptation.
Nevertheless, the experimental data obtained during development can help engineers understand which aerodynamic approaches are effective, which compromises deliver the best results and which design directions deserve further investigation.
This means that the value of an aerodynamic upgrade cannot be measured exclusively through the tenths of a second gained over a single lap. Every development programme can also produce knowledge that influences the technical decisions made for a future car.
For Ferrari, continuing to investigate new bodywork concepts in 2026 could therefore contribute to the design process for 2027, even if the final components used on the next car look significantly different.
Ferrari can use the Austin upgrades as a real-world test
The United States Grand Prix represents an important opportunity for Ferrari to evaluate its aerodynamic developments under genuine racing conditions. The Circuit of the Americas combines several different challenges, making it a useful venue for examining how the upgraded SF-26 behaves across a variety of corner types and operating demands.
The opening sector features fast corners and rapid changes of direction, while other sections require strong traction, stability and an effective compromise between aerodynamic downforce and straight-line speed.
These characteristics make Austin particularly relevant when examining the relationship between aerodynamic efficiency and overall vehicle behaviour. Engineers will need to establish whether the new components provide the expected benefits and whether the car’s response matches the predictions generated during development.
Ferrari’s evaluation will also extend to how well the updated configuration performs in different conditions. The team’s engineers can compare the behaviour observed on track with their existing simulations and wind tunnel results, looking for areas where the two sets of information agree or diverge.
The 2026 United States Grand Prix weekend at Austin will provide the setting for this assessment, with the available running offering opportunities to understand the upgraded package before the race.
Importantly, introducing a substantial aerodynamic development does not necessarily mean its full potential will become apparent immediately. Even a promising upgrade may require further setup work before the team can obtain the performance anticipated during its design.
Why car setup will be crucial to unlocking the SF-26 updates
CFD simulations and wind tunnel experiments allow Formula 1 teams to reduce uncertainty before bringing new components to the circuit, but neither method can reproduce every condition encountered during a race weekend.
Once the upgraded parts have been fitted to the car, engineers must verify the information collected during development and identify any adjustments necessary to achieve the most effective overall balance.
Setup therefore becomes particularly important. Ride heights, stiffness settings and suspension adjustments need to be matched to the aerodynamic characteristics of the car while also accounting for tyre behaviour.
Because aerodynamic performance changes as the car moves through different operating conditions, the most effective configuration may not be immediately obvious. Engineers must examine how the updated package behaves and determine which adjustments help it deliver consistent performance.
This process may explain why significant developments sometimes require additional track running before their full benefits can be understood. Initial results do not necessarily provide a complete picture of what an upgrade can achieve once its characteristics have been properly assessed.
The importance of collecting representative track data also extends to evaluating performance over longer runs. Ferrari’s behaviour during practice sessions can be examined alongside broader Formula 1 trends through the F1 practice and long-run analysis, which provides additional context for comparing on-track performance.
Ferrari’s bigger objective is to build knowledge for 2027
The central consideration behind Ferrari’s continued SF-26 development is that Formula 1 engineering does not end with the immediate result of an upgrade. Every new aerodynamic solution needs to be tested, its behaviour understood and its effects compared with the predictions made during the design process.
By examining differences between simulated and observed performance, teams can refine their development tools and improve their understanding of the aerodynamic behaviour of their cars. These lessons can then influence the direction of future projects.
Ferrari’s decision to continue developing the SF-26 may consequently offer two distinct benefits. The first is the possibility of extracting additional performance during the final races of the 2026 championship. The second is the opportunity to collect information that could support the design and development of its 2027 Formula 1 car.
Neither outcome is guaranteed. Not every aerodynamic update produces the improvements originally anticipated, and lessons learned from one car cannot always be applied directly to another, particularly when regulations change.
The usefulness of the information gathered will depend on the quality of the data and the engineers’ ability to interpret it correctly. Even when a particular concept does not deliver the expected performance, understanding why it behaves differently can help inform subsequent development decisions.
For Maranello, the challenge is therefore to transform the Austin upgrades into meaningful improvements for the SF-26 while also building a stronger technical foundation for the future.
The behaviour of the updated Ferrari during the United States Grand Prix weekend, together with the technical feedback gathered over the following sessions, will provide the first indications of whether the latest development work is meeting expectations. Beyond the immediate pursuit of performance in 2026, those findings could prove valuable as Ferrari continues preparing its next Formula 1 car.
