Ferrari used its Monza filming day to validate a technical package focused on aerodynamic efficiency, with the promotion and further development of the “Macarena” wing acting as a clear and increasingly important sign of a potential shift in the overall development direction of the SF-26 project.
Although the official schedule for the day was simply labelled as a “filming day,” those familiar with Formula 1 development programmes, particularly within Ferrari and other top teams like Red Bull, Mercedes, and McLaren, know that similar events often reveal far more than the official terminology suggests. Ferrari’s day at the Autodromo Nazionale Monza was not limited to producing polished social media content, promotional footage, or marketing visuals featuring Charles Leclerc, Lewis Hamilton, and the team environment under cinematic lighting conditions. Instead, it represented structured and highly valuable technical running, carefully organised within the strict 200-kilometre limitation imposed by Formula 1 regulations, but clearly designed with performance evaluation for upcoming race weekends in mind, including the Miami Grand Prix.
The Ferrari SF-26 was deployed with a very specific engineering objective: to verify whether the expectations generated by simulator correlation work in Maranello match real-world aerodynamic and mechanical behaviour on track conditions. At the same time, the team evaluated an initial development package designed to modify and refine the overall aerodynamic characteristics of the car. As Ferrari technical director Loic Serra had already indicated in recent days, the factory in Maranello had not slowed down its development cycle, continuing parallel work in the wind tunnel, CFD simulations, and track correlation programmes. Monza therefore functioned as a critical real-world benchmark for validating the progress achieved internally.
The choice of Monza as the testing venue was far from random or purely logistical. The Temple of Speed is widely recognised across Formula 1 as one of the most revealing circuits in the world when it comes to identifying aerodynamic inefficiencies. Long straights, like the Rettifilo and the back straight between Ascari and Parabolica, immediately expose drag levels, with every additional kilogram of aerodynamic resistance translating directly into lost lap time and reduced top speed. At the same time, heavy braking zones into Variante del Rettifilo and Variante Ascari allow engineers to assess how effectively a car transitions between low-drag and high-downforce configurations. It is precisely in this sensitive balance between straight-line efficiency and cornering stability that the SF-26 has shown certain inconsistencies during the opening phase of the season.
Ferrari SF-26: a wing that “dances”
The most technically interesting element of the entire Monza filming day revolves around a component internally referred to as the “Macarena” wing. The nickname, attributed to Ferrari’s team principal Frederic Vasseur, refers to its dynamic and slightly flexible behaviour, and it is not accidental in its description. The concept introduces a more adaptive aerodynamic response compared to previous Ferrari rear wing solutions used on the SF-26 during earlier races.
The fundamental idea behind the concept is to reduce aerodynamic drag on straights, when excess downforce becomes a disadvantage in terms of top speed, while still preserving sufficient grip, stability, and load in high-speed and medium-speed cornering phases where aerodynamic performance is essential for lap time.
This concept itself is not entirely new within Ferrari’s development history, as the component was initially tested during the Bahrain pre-season winter running programme and later briefly revisited during the Chinese Grand Prix weekend before being temporarily set aside for further refinement. However, its renewed development and reintroduction during this Monza filming day clearly indicate a shift in Ferrari’s engineering mindset. The team has refined the component by reworking the geometry of the wing support structures, adjusting load paths, and improving the opening and closing mechanisms to ensure greater consistency across varying speed ranges.
The technical department at Maranello is no longer focused on simply increasing downforce at all costs, a philosophy that historically characterised several Ferrari projects in the hybrid era. Instead, the current objective is to significantly improve overall aerodynamic efficiency and balance, making the SF-26 more versatile and competitive across a broader range of circuits, from high-speed tracks like Monza and Baku to more technical layouts such as Monaco or Singapore. In engineering terminology, this relates to the so-called “efficiency map,” which defines the operating window in which the car performs at its optimal level. Ferrari’s current development direction aims to shift that optimal window towards conditions that are more competitive in high-speed sections, where the team has historically lost ground to rivals.
Monza amplifies everything, for better and worse
There is a clear and well-established reason why Formula 1 teams choose specific circuits for specific testing programmes. Monza does not hide inefficiencies; instead, it exposes them with extreme clarity and technical brutality. It is also one of the most effective circuits for collecting hybrid system data, as braking and acceleration phases are highly structured, predictable, and easy to analyse from both a mechanical and energy recovery perspective.
The work carried out during the Ferrari filming day did not stop at the rear wing development alone. It also included modifications to the floor geometry of the SF-26, refinements to the halo aerodynamic structures based on previously circulated trackside images, and a broader revision of aerodynamic configurations as a complete package. According to paddock information, weight optimisation was also part of the programme. This type of development, although often less visible than aerodynamic upgrades, can deliver significant performance gains, as even small reductions in mass have a direct and measurable impact on lap time, tyre degradation, and overall vehicle dynamics.
However, raw performance data collected during short filming day runs is only one part of the overall evaluation process. The second and equally important part is correlation analysis: determining how closely real-world data matches the predictions generated by Ferrari’s simulator systems in Maranello. This step is critical in modern Formula 1 development, as it determines whether future upgrades can be reliably predicted or whether further model refinement is required. If the Monza data aligns closely with expectations, Ferrari will gain a more stable and confident foundation for upcoming developments and race-specific setups.
On a parallel technical track, the Ferrari engineers and technicians also focused on testing new electronic engine mapping configurations, particularly aimed at addressing perceived weaknesses in energy recovery and electrical deployment when compared to Mercedes power units, which have shown strong performance in hybrid energy management. Whether these adjustments have achieved the desired improvement will only become clear once the package is evaluated under full competitive race conditions, as no official performance figures or comparative data have been released at this stage.
Miami becomes the first real test
All the technical work carried out during the Monza filming day ultimately converges towards one key objective: the Miami Grand Prix. It is in Miami that the updated SF-26 package is expected to appear in a more complete and integrated form, moving beyond controlled testing conditions and into full competitive race scenarios against direct rivals Mercedes and potentially also Red Bull and McLaren, depending on their development progress.
This will not represent an immediate or dramatic revolution in performance, but rather a first structured and measured step in a clearly defined development direction. Ferrari appears to be building its progression incrementally, focusing on stability, correlation accuracy, and gradual efficiency gains rather than aggressive one-off upgrades.
However, there is a broader technical and strategic implication that goes beyond pure lap time performance. Introducing more sophisticated aerodynamic solutions, like a rear wing with controlled flexibility or adaptive movement characteristics, inevitably raises new questions regarding operational management during race conditions, long-run consistency, and mechanical reliability over a full Grand Prix weekend. If the balance between performance gain and stability is not correctly achieved, the potential risks could outweigh the advantages in straight-line speed.
This is precisely why the Ferrari engineers chose to introduce and validate these developments during a controlled regulatory window, using the filming day opportunity to gather initial real-world feedback before committing the package to a full race weekend environment. It is also important to consider that the Miami Grand Prix will be held under the sprint format, which significantly reduces preparation time, making early validation even more critical for competitive readiness.
Ferrari appears to have targeted one of the most visible and persistent weaknesses of the SF-26 project: aerodynamic inefficiency on high-speed sections and inconsistent balance between straight-line performance and cornering stability. The key question moving forward is whether the efficiency gains achieved through this updated package will be sufficient to meaningfully close the performance gap to the leading team, and extend the performance advantage over Red Bull and McLaren, and whether the new aerodynamic philosophy will remain effective across a wide variety of circuits beyond the unique characteristics of Monza.
As always in Formula 1, regardless of simulation data, wind tunnel results, or filming day impressions, the final and only definitive answer will come from the track itself.
