Ferrari’s latest aerodynamic upgrade has attracted praise from Formula 1 analyst Ted Kravitz, who identified an unusual floor-edge design on Charles Leclerc’s SF-26 ahead of the 2026 United States Grand Prix. The new component, which has been likened to a snowplough, forms part of an aggressive development package intended to increase downforce and improve the efficiency of airflow beneath the car.
After examining the revised floor and diffuser at the Circuit of The Americas, Kravitz expressed particular admiration for the engineering solutions introduced by Ferrari. The changes complete a development programme that began at the Madrid Grand Prix and represent the team’s final planned chassis upgrades of the 2026 Formula 1 season. Maranello hopes the package will help Lewis Hamilton and Charles Leclerc challenge Red Bull for victories during the remaining races.
Ted Kravitz highlights Ferrari’s unusual new floor design at Austin
Speaking on Sky Sports F1, Ted Kravitz focused on the distinctive changes Ferrari has made to the leading edge of the SF-26 floor. One of the most noticeable features is the revised arrangement of the aerodynamic turning vanes, with the outermost element now extending beyond the others.
The design caught the analyst’s attention because of the unconventional way it attempts to manage airflow entering the underside of the car. Kravitz explained that Ferrari has introduced an additional protruding element, informally described as a snowplough, which is intended to capture air and direct it beneath the floor towards the diffuser.
By guiding airflow into this region, Ferrari is seeking to improve how effectively the underfloor aerodynamic system produces downforce. The modification is not simply a change to the appearance of the car. It forms part of a broader effort to optimise the relationship between the floor’s leading edge and the diffuser at the rear.
Kravitz was particularly impressed by the aggressive nature of the solution. Although Ferrari has encountered difficulties on track during the season, he believes its design department continues to demonstrate considerable creativity in developing the SF-26.
The floor-edge modification is one of four areas included in the latest package. Ferrari has revised the floor body, floorboard, sidepod inlet and diffuser, with the changes designed to work together rather than function as isolated developments. A more detailed explanation of the components can be found in our breakdown of Ferrari’s four SF-26 aerodynamic upgrades for Austin.
Ferrari’s new diffuser aims to generate more efficient downforce
Another important element of the United States Grand Prix package is the revised diffuser. According to the technical information discussed by Ted Kravitz, Ferrari has increased its volume with the intention of generating greater aerodynamic load while improving efficiency.
The diffuser plays a central role in the performance of the floor because it manages the expansion of airflow beneath the rear of the car. Its effectiveness depends not only on its own geometry but also on the characteristics of the air arriving from further forward.
This explains the connection between Ferrari’s unusual floor-edge arrangement and the redesigned diffuser. The additional guide element is intended to improve the flow entering the underfloor region, while the revised diffuser aims to make more effective use of that airflow to produce downforce.
Kravitz identified both components as particularly significant developments. He also highlighted the engineering difficulty associated with the guide vane because of its attachment to the monocoque, which introduces additional considerations relating to crash-impact testing.
Ferrari’s approach therefore involves more than a conventional aerodynamic adjustment. The team has adopted a distinctive arrangement that requires the relevant structural and safety requirements to be considered alongside the intended performance benefits.
Ferrari completes development package first introduced at Madrid GP
The Austin changes represent the conclusion of a development programme that began earlier in the 2026 season. Ferrari introduced the initial elements of its revised aerodynamic concept at the Madrid Grand Prix, the 14th round of the championship and the first Spanish Grand Prix held at the new Madring circuit.
That package included a new floorboard and the return of a three-part bargeboard arrangement. The developments provided the foundation for the additional aerodynamic modifications now introduced at the Circuit of The Americas.
Ted Kravitz explained that the latest parts should be considered the completion of that earlier upgrade programme rather than an entirely unrelated direction. The new floor and diffuser developments extend the work already undertaken by Ferrari in its search for greater aerodynamic performance.
The Scuderia has also revised the sidepod inlet area, including changes to the undercut beneath the sidepods. Reports ahead of the United States Grand Prix suggested that Ferrari had been working against time to have the updated sidepod design ready for Austin.
The revised undercut is intended to improve airflow management around the bodywork, complementing the modifications to the floor and rear aerodynamic surfaces.
Ferrari’s package is among the largest introduced at the event, although several rival teams have also brought new components. The wider development picture is examined in our report on Ferrari’s Austin upgrades and the new parts introduced by six rival teams.
Loic Serra’s Ferrari technical department maintains aggressive SF-26 approach
Ferrari’s chassis development programme is overseen by technical director Loic Serra, whose department has continued exploring ambitious aerodynamic concepts throughout the first season of Formula 1’s new regulations.
Team principal Fred Vasseur gave the engineering group considerable freedom to pursue an aggressive technical approach for 2026. That philosophy has already produced several distinctive solutions, including the SF-26’s FTM exhaust flap and the unconventional Macarena rear wing.
The latest floor arrangement follows the same philosophy. Rather than restricting development to modest revisions of established components, Ferrari has continued examining alternative ways of managing airflow and generating aerodynamic load.
Ted Kravitz’s assessment reflects that distinction between the creativity of Ferrari’s design office and the competitive difficulties occasionally experienced on track. The former has continued to attract attention even when the latter has prevented the team from converting its aerodynamic strengths into consistent victories.
The development of Ferrari’s chassis has been particularly relevant because the SF-26 has frequently demonstrated strong performance in medium- and high-speed corners. Its downforce characteristics have provided an important foundation, although that advantage has not always translated into overall superiority across a complete Grand Prix weekend.
Ferrari hopes Austin upgrades will address high-speed cornering weakness
Despite its established aerodynamic strengths, Ferrari has identified areas where the SF-26 still needs improvement. Reports suggest the team hopes its latest floor development will reduce the car’s vulnerability in high-speed corners, following an evaluation of data gathered by Charles Leclerc and Lewis Hamilton with previous upgrade packages.
That objective is particularly significant because a Formula 1 car’s performance cannot be assessed solely through its peak downforce figures. The amount of aerodynamic load generated, how efficiently it is produced and how consistently it can be maintained all influence the driver’s ability to exploit the car.
Ferrari’s latest modifications are intended to increase downforce while improving the efficiency of the floor and diffuser system. The team will therefore be looking for gains that translate into usable performance through different sections of the circuit.
The importance of this challenge was already apparent in the technical preparations for Austin, where Ferrari targeted improvements in high-speed cornering through its revised aerodynamic package.
The United States Grand Prix provides an important opportunity to evaluate those changes against the competition. With Ferrari expecting a significant performance improvement, the team’s engineers will be examining whether the new components deliver the anticipated benefits during practice, qualifying and the race.
Can Ferrari’s final SF-26 upgrade help challenge Red Bull?
The timing of Ferrari’s final planned chassis upgrade reflects the competitive challenge facing the team during the closing stages of 2026. Lewis Hamilton and Charles Leclerc have each claimed one Grand Prix victory this season, but Red Bull has recently strengthened its position at the front.
Lewis Hamilton secured his first victory for Ferrari at Barcelona, while Charles Leclerc won the British Grand Prix at Silverstone. However, Max Verstappen subsequently claimed consecutive victories at Sepang and Singapore, underlining Red Bull’s improving competitiveness.
Ferrari therefore arrives at Austin seeking to recover ground against a rival that has gained momentum. The new floor, diffuser and sidepod modifications are intended to provide the additional aerodynamic performance needed to make that challenge more effective.
According to Ted Kravitz, there are considerable expectations within the Ferrari garage surrounding the latest components. He explained that the team hopes the completed upgrade package will improve its prospects of beating Red Bull to the top step of the podium.
The United States Grand Prix is the 18th round of the 23-race season, leaving Ferrari with a limited number of opportunities to evaluate and exploit its final chassis developments before attention moves fully towards the following championship.
For Charles Leclerc and Lewis Hamilton, the objective is to translate the engineering department’s latest work into stronger on-track performance. The updated SF-26 represents another attempt to improve the balance between aerodynamic load and efficiency, with its distinctive floor-edge design illustrating how far Ferrari is prepared to explore new technical solutions.
The potential importance of those developments also extends to the team’s longer-term direction. Our examination of Ferrari’s final SF-26 evolution and the weaknesses it aims to address explains why the concluding stages of the current development programme remain significant.
Ted Kravitz has already delivered an enthusiastic assessment of the package’s design, particularly the unconventional floor guide element and larger diffuser. Ferrari’s next challenge is to demonstrate that the aerodynamic creativity seen in the Austin garage can produce the performance required to compete with Red Bull for victories.
