The Ferrari team has arrived in Spain with its most ambitious upgrade package of the 2026 Formula 1 season, introducing significant aerodynamic modifications to the SF-26 at a pivotal moment in their campaign.
These developments come as Lewis Hamilton continues to build momentum following a series of encouraging performances, including Ferrari’s strongest weekends of the season in Monaco and Canada. While Mercedes continues to set the benchmark in Formula 1, Ferrari hopes that its largest upgrade package to date will finally provide the tools needed to compete for victory.
While Charles Leclerc will debut the new specification, including a copy of Hamilton’s braking system, during Friday practice, recent races have increasingly suggested that Hamilton is Ferrari’s strongest hope of challenging Mercedes in the short term. The seven-time world champion has become progressively more comfortable with the SF-26, whereas Leclerc has often struggled to unlock the car’s full potential throughout a race weekend.
Ferrari remains committed to its original development plan
Several teams have adjusted their development schedules this season following calendar changes and shifting priorities, with some bringing upgrades forward and others delaying them until later races.
Ferrari, however, has remained committed to its original roadmap under technical director Loïc Serra.
The result is a comprehensive package affecting virtually every major aerodynamic area of the SF-26, from the front wing to the diffuser.
Leclerc tested the upgraded package during FP1 in Barcelona, while Ferrari junior Dino Beganovic replaced Hamilton for the opening session and test the previous specification.
This dual programme provided Ferrari with valuable comparative data, while enabling the team to manage its supply of new components carefully throughout the weekend.
Front wing revisions continue the aerodynamic overhaul
The package builds upon Ferrari’s recently introduced front wing concept.
Changes include updates to the upper and lower footplate sections, new vertical aerodynamic appendages, and revised Venturi-style channels beneath the wing. Ferrari has also modified the endplate design and added a new diveplane arrangement.
The flap geometry has been revised and the active aerodynamic adjustment mechanism relocated inside the nose structure. This solution mirrors concepts already adopted by several rival teams and is intended to improve operational efficiency during race weekends.
Ferrari has taken its unique floor concept further than any rival
The most eye-catching changes are found underneath the SF-26.
Ferrari has continued to develop an innovative floor concept that first appeared earlier this season, and which remains one of the most distinctive aerodynamic solutions on the grid.
At the floor entrance, where airflow is directed into the underbody tunnels, Ferrari has traditionally used a horizontal profile to divide the incoming airflow. For Barcelona, however, this concept has evolved significantly.
The updated design features a biplane-style entrance arrangement with a more pronounced, wing-like horizontal element that splits the lower floor inlet into two separate channels.
This unique profile extends longitudinally across the floor entrance, highlighting Ferrari’s willingness to pursue a different aerodynamic direction to many of its rivals.
Redesigned sidepods target a key Ferrari weakness
Ferrari has also revised the external shape of the sidepods to address one of the SF-26’s major shortcomings.
The new design features a straighter profile and a bulkier leading section, which is intended to push the turbulent airflow generated by the front tyres further away from the car.
Since pre-season testing, improving aerodynamic efficiency has been a major objective, with Ferrari identifying airflow management as an area requiring further development after the opening rounds.
The sidepod revisions are therefore intended to generate cleaner airflow throughout the car and help unlock greater overall performance.
Rear-end revisions complete Ferrari’s most significant update package
Additional changes have been made around the sensitive floor-edge region ahead of the rear wheels.
The aim is to improve floor sealing and prevent unwanted airflow disturbances from reducing diffuser performance. Ferrari’s latest solution follows a similar development direction to concepts recently introduced by Mercedes, incorporating additional vertical elements within the floor-edge openings.
The package is completed by further updates to the diffuser and rear aerodynamic structures. The diffuser keel, trailing-edge geometry and several aerodynamic elements associated with the complex rear-end architecture have been revised.
Taken together, these changes represent Ferrari’s most significant development of the season to date.
Hope for Hamiltons’ first win for Ferrari
Equally importantly, these changes come at a time when Hamilton appears to be getting more out of the SF-26 than at any other point in the season.
While Leclerc remains central to Ferrari’s long-term ambitions, recent weekends have suggested that the car’s balance and characteristics are increasingly aligning with Hamilton’s driving style.
If the upgrade package delivers the expected gains, Barcelona could provide the clearest opportunity yet for Hamilton to challenge Mercedes head-on and potentially secure Ferrari’s first Grand Prix victory since he joined the Scuderia.
