Ferrari is preparing a fourth aerodynamic upgrade package for the SF-26, with the United States Grand Prix in Austin expected to become the key date for the final major step in the car’s 2026 development programme. The Maranello team has fallen behind after McLaren’s recent improvements pushed the Woking squad forward in the competitive order, even making it more competitive than Mercedes in recent races.
Ferrari does not believe the SF-26 itself has suddenly become less competitive. Instead, its rivals have developed at a faster rate, leaving the Scuderia outside the podium positions during a difficult recent run. Maranello’s response is set to arrive with a fourth upgrade package designed to correct the development direction taken after Zandvoort and extract more performance from the current car.
Ferrari prepares fourth SF-26 upgrade after McLaren’s progress
McLaren made an important step in Hungary with aerodynamic modifications focused around the floor, before introducing further circuit-specific solutions for faster tracks. The Woking team has also improved its understanding of both the tyres and the power unit, helping it move forward in the competitive hierarchy.
Ferrari, by contrast, already knew that the floor introduced at Zandvoort would not deliver a major performance increase. Changes were made while that development was still in progress as the technical direction evolved, prompting the team to postpone some of the other planned interventions rather than rushing them onto the SF-26.
The technicians working under Loïc Serra therefore chose not to accelerate production simply to meet the Dutch Grand Prix development window. Instead, Ferrari gave its aerodynamic department additional time to study several areas and maximise the performance potential of the next package. The broader evolution of the car can be followed through ScuderiaFans’ Ferrari technical analysis coverage.
Why Ferrari delayed part of its development programme
The decision effectively meant accepting a compromise through the middle part of the season. Rather than introducing an incomplete sequence of solutions immediately, Ferrari preferred to delay further changes in the hope of increasing their overall impact when they eventually reached the car.
Work at Maranello has continued in particular around the outer edge of the floor, with the engineers attempting to meet their development targets while also respecting Formula 1’s cost cap. This is expected to form part of a more substantial evolution of the SF-26 rather than another isolated modification.
The department led by Diego Tondi has carried out an intensive development programme in the wind tunnel, repeatedly combining new and older components to evaluate different configurations. Some of the solutions studied did not produce the results Ferrari had expected from the factory data, forcing the aerodynamic group to continue refining the package rather than approving every concept for production.
That approach helps explain why Maranello did not simply bring every available update to Zandvoort. The team preferred to extend the development phase and concentrate the postponed changes into a more complete package.
Austin expected to debut Ferrari’s major floor evolution
The United States Grand Prix at the Circuit of the Americas, scheduled towards the end of October, is now expected to mark the debut of the delayed modifications. Their position in the remaining campaign can be seen in the 2026 Formula 1 calendar.
The package should include an important evolution of the floor together with changes to other areas of the SF-26 that Ferrari’s aerodynamicists have been developing since the Catalunya Grand Prix in June. In this sense, Austin represents the culmination of work that has been continuing for several months rather than a response designed only in the wake of the latest disappointing results.
Logistics are also part of the reason for choosing the Texas event, while the characteristics of the Circuit of the Americas are considered useful for evaluating whether the latest aerodynamic work has delivered the expected progress. The weekend could therefore become a particularly important reference point for Ferrari’s remaining 2026 ambitions.
Austin could reveal whether Ferrari can return to winning contention
The significance of the fourth upgrade package extends beyond individual aerodynamic gains. Ferrari wants Austin to provide a clearer answer about whether the SF-26 can return to fighting for Grand Prix victories before the end of the season.
The team has recently found itself behind rivals that have progressed more quickly, with McLaren’s development rate particularly significant. Ferrari’s recent difficulties have already raised questions over how aggressively the SF-26 should continue to be developed, an issue also reflected in the wider debate over Ferrari’s remaining 2026 development priorities.
However, continuing to work on the current car does not necessarily mean sacrificing the future programme. Ferrari believes that elements of the work being carried out on the SF-26 can also remain relevant beyond the present campaign, with current SF-26 development also contributing to the 2027 project.
Ferrari still sees the power unit as the SF-26’s underlying limitation
Despite the planned aerodynamic progress, the SF-26 is still not regarded as a genuinely winning car because of what is described as the original weakness of its engine concept. The fourth package is intended to improve the chassis and aerodynamic performance, but it cannot completely remove every limitation built into the current technical package.
This makes the remaining development programme a balancing act. Ferrari wants to extract more from the SF-26 and determine whether the car can return to victory contention, while simultaneously gathering information that can strengthen its longer-term technical direction.
Towards 2027, the current power unit concept is set to be completely overhauled. Until then, Austin should provide one of the clearest tests of whether Ferrari’s decision to postpone part of its aerodynamic programme was worthwhile and whether the fourth upgrade package can deliver the final meaningful step expected from the SF-26 in 2026.
