Ferrari is preparing to introduce its latest aerodynamic upgrade package for the SF-26 at the 2026 United States Grand Prix, with a new floor designed to improve downforce, aerodynamic stability and tyre management. The objective is to give Charles Leclerc and Lewis Hamilton a more predictable car at Austin, allowing the team to move away from the extreme setups used in recent races and unlock a broader operating window.
The Maranello team is playing one of its final development cards of the season. This will be the fourth upgrade package planned for 2026, with the technical department already concentrating much of its attention on the SF-27. Ferrari nevertheless believes there is still performance to extract from its current Formula 1 car before the championship reaches its conclusion.
Charles Leclerc’s second-place finish at the Singapore Grand Prix, combined with Lewis Hamilton’s disappointing sixth position, strengthened Ferrari’s hold on second place in the Constructors’ Championship. However, the Scuderia’s ambition extends beyond consolidating that position. It wants to return to winning races, something it has not achieved since the British Grand Prix in early July.
There is also frustration surrounding the power unit. The latest changes associated with the second evolution of the 067/6 engine, introduced through ADUO2, have not delivered the on-track improvements Ferrari had anticipated. Another significant step is therefore needed if the Italian team is to finish a campaign marked by repeated fluctuations in performance on a positive note.
Ferrari’s new SF-26 floor aims to improve aerodynamic stability
The technical group led by Loic Serra has been working to extract the remaining potential from the SF-26, a car that is now approaching its development ceiling. Ferrari invested heavily in improvements during the opening part of 2026, and next year’s challenger is expected to be substantially different from the current machine.
The Austin package was approved in time using the final wind tunnel development updates, although there is still uncertainty over whether every planned component will be available for the United States Grand Prix.
One element is certain: Ferrari will introduce an evolved floor. The team has also been working against the clock to ship revised sidepods featuring different bodywork. Any components that are not ready for the Circuit of the Americas should make their debut in Mexico City the following week.
The new floor is intended to generate greater downforce from the car’s underbody, or alternatively maintain the current level of aerodynamic load while allowing Ferrari to use a less rigid suspension setup.
This distinction is particularly important. The objective is not simply to produce more aerodynamic load, but to widen the SF-26’s operating window and make its behaviour more consistent across different types of corners.
Ferrari wants a more stable aerodynamic platform in both slow-speed and medium-to-high-speed sections, reducing the need for the particularly stiff configurations adopted recently. That should also provide greater scope to protect the tyres without sacrificing the aerodynamic performance needed to remain competitive.
The importance of this issue was already evident in the Ferrari SF-26 technical analysis from Singapore, where rear-end behaviour and tyre management emerged as important factors in the team’s performance.
Why Austin will be a demanding test for Ferrari’s upgrades
The Circuit of the Americas should provide a particularly revealing indication of Ferrari’s progress over the final six Grands Prix of the season. The Texas venue requires a medium-downforce configuration and features a varied selection of corners that can expose the strengths and weaknesses of a Formula 1 car.
One of the biggest challenges comes from the circuit’s increasingly uneven surface. The ground beneath the asphalt is not completely stable, and the bumps become more pronounced each year. These irregularities can cause sudden losses of grip and disrupt the aerodynamic load generated by the car.
The famous Snake section adds another demanding element. Its sequence of high-speed changes of direction places considerable lateral loads on the tyres, making the relationship between aerodynamic balance and mechanical setup especially important.
For Charles Leclerc and Lewis Hamilton, the ability to maintain a consistent aerodynamic platform without relying on excessive suspension stiffness could therefore prove essential.
Rather than pursuing maximum downforce at the expense of overall balance, Ferrari is attempting to create a more adaptable SF-26 that performs consistently across a wider range of corner speeds and track conditions.
The wider significance of the development has already been highlighted by Charles Leclerc’s concerns about Ferrari losing ground to its Formula 1 rivals, making the Austin upgrade an important opportunity to assess how much competitiveness remains in the existing package.
Ferrari studies revised sidepods to reduce drag and improve energy deployment
Alongside the new floor, Ferrari is pursuing improvements around the radiator inlets and sidepods, with the objective of increasing overall aerodynamic efficiency.
Reducing drag should allow the power unit’s available energy to be distributed and used more effectively over the course of a lap. This would be particularly valuable given the limitations that have affected the latest evolution of Ferrari’s 067/6 power unit.
The revised design is expected to feature a smaller frontal radiator opening. Importantly, this reduction should not compromise cooling performance, because the existing cooling system has not fully exploited the opportunities offered by the engine’s thermal characteristics.
Another interesting aspect will be Ferrari’s chosen sidepod philosophy. Rival teams have pursued distinctly different approaches, with some adopting heavily sloping sidepods while others have retained a more pronounced sidepod wall to manage the aerodynamic losses caused by turbulence from the front wheels.
Ferrari’s final configuration will reveal which development direction its engineers believe offers the best compromise between airflow management, drag reduction and overall aerodynamic performance.
The combination of floor, sidepod and bodywork changes could therefore offer more than a simple increase in peak downforce. The intended improvement is a car that produces its aerodynamic performance more efficiently and delivers that performance across a broader range of conditions.
Ferrari faces a crucial battle with Red Bull, Mercedes and McLaren
Ferrari will not be the only leading team bringing developments into the final part of the championship.
McLaren has announced further upgrades, while Mercedes plans to field a more developed version of its W17, including the new wing that underwent only a brief test at Singapore.
Both teams are aiming to challenge Red Bull, which completed its upgrade programme at Baku and subsequently won at Sepang and Singapore with Max Verstappen.
Ferrari’s challenge is to establish where its latest developments place the SF-26 in this competitive picture. The team cannot afford to rely exclusively on its Singapore result, particularly as its rivals continue to extract performance from their own packages.
The Austin weekend will therefore be important both for Ferrari’s immediate performance and for understanding the remaining limitations of its 2026 car. Fans preparing for the event can also consult the 2026 United States Grand Prix schedule and Circuit of the Americas guide.
For Ferrari supporters, Austin also brings back memories of Charles Leclerc’s victory at the circuit in 2024. That success still feels relatively recent, yet the Scuderia now arrives in Texas searching for the improvement needed to return to the front.
Whether the new SF-26 floor and associated aerodynamic changes can deliver that breakthrough remains to be seen. What is clear is that Ferrari has identified aerodynamic stability, setup flexibility and efficiency as the key areas in which it hopes to make its final significant gains of the 2026 season.
