Ferrari used its Monza filming day to explore a bold aerodynamic concept that had previously raised questions with the FIA, as the SF-26 was spotted running with modified Halo-mounted winglets ahead of the Miami Grand Prix. The appearance of these revised elements, combined with a broader upgrade package, underlines Ferrari’s aggressive approach to development in the 2026 Formula 1 season.
Despite strict operational restrictions typically associated with filming days, several images from the private test session surfaced online, offering valuable insight into the direction taken by the Maranello-based team. The outing was not only focused on gathering promotional footage, but also served as a critical opportunity to validate new components designed to improve aerodynamic efficiency and overall car balance.
SF-26 Halo fins return in revised configuration
One of the most intriguing aspects of the Monza session was the reappearance of aerodynamic appendages mounted on the Halo structure of the Ferrari SF-26. These elements had previously been deemed non-compliant during the Chinese Grand Prix weekend, primarily due to concerns related to the materials used in their construction.
However, the version tested at Monza appears to have undergone significant revisions. The updated design features carbon-laminated fins integrated directly into the Halo, suggesting that Ferrari has worked to address the FIA’s earlier concerns while retaining the aerodynamic intent of the concept.
Although the fins are not transparent, their extremely compact size and carefully considered positioning are understood to minimise any potential impact on driver visibility. Both Charles Leclerc and Lewis Hamilton were able to complete their respective programmes without reporting visibility issues, indicating that the revised solution may now meet both safety and performance criteria.
A broader upgrade package in development
The Halo fins were only one element of a wider set of upgrades Ferrari evaluated during the Monza test. The SF-26 was also equipped with a revised front wing assembly and an updated floor, both aimed at increasing downforce consistency and improving airflow management across different phases of the lap.
In addition, Ferrari continued to refine its much-discussed “Macarena” rear wing concept, which is expected to become a permanent feature of the car following earlier experimental runs. The integration of these components reflects a coordinated development strategy, with each element designed to work in synergy rather than as isolated upgrades.
Charles Leclerc and Lewis Hamilton played a key role in providing feedback on the behaviour of the updated car, allowing Ferrari engineers to correlate real-world data with simulation models. Their input is considered essential in determining whether the new aerodynamic solutions can deliver consistent performance gains under race conditions.
Regulatory challenges and strategic decisions
The reintroduction of Halo-mounted aerodynamic elements highlights the fine balance teams must strike between innovation and regulatory compliance in modern Formula 1. The FIA’s initial rejection of the concept in China demonstrated the strict scrutiny applied to even minor design details, particularly when they involve safety-critical structures like the Halo.
By presenting a revised version at Monza, Ferrari appears to be testing the boundaries of the regulations once again, while attempting to remain within acceptable limits. Whether this solution will ultimately receive full approval for race use remains uncertain, and further clarification from the governing body could be required before it is officially deployed in competition.
Focus shifts to Miami Grand Prix debut
With the Miami Grand Prix approaching, the Maranello engineerd and technicians now face a key decision regarding which elements of its upgrade package will be introduced on race weekend. While the revised Halo fins have shown potential, the team may opt for a cautious approach if additional validation is deemed necessary.
In contrast, other components like the new floor and front wing are expected to play a more immediate role, forming the backbone of Ferrari’s effort to close the gap to its main competitors in the 2026 Formula 1 championship.
The coming race in Miami will provide the first true competitive benchmark for these developments, offering a clearer indication of whether Ferrari’s aggressive innovation strategy can translate into measurable on-track performance gains.
Final analysis
Ferrari’s decision to revisit the Halo wing concept, even in a revised form, reflects the team’s determination to extract every possible aerodynamic advantage from the SF-26. In a season where development speed is critical, such bold experimentation could prove decisive.
However, regulatory approval remains a key variable. If the updated design is cleared for racing, it could represent a subtle yet effective performance gain. If not, Ferrari will need to rely on the rest of its upgrade package to maintain momentum in the development race. Either way, the Monza filming day has confirmed that Maranello is pushing hard on all fronts in its pursuit of success in Formula 1 2026.
