Ferrari is continuing development of the SF-26, with a new package set to arrive at Sepang featuring changes to the T-tray, revised aerodynamic elements near the diffuser and an optimisation of the hydraulic system controlling the car’s active aerodynamics. The work led by Chassis Technical Director Loïc Serra is aimed not only at improving the current car, but also at laying technical foundations for Ferrari’s 2027 project.
According to Rosario Giuliana of AutoRacer.it, the Maranello team is continuing to refine the competitiveness of the SF-26 while simultaneously using its 2026 development programme to prepare solutions and concepts that could influence next year’s car.
Ferrari SF-26 upgrades for Sepang target T-tray and active aerodynamics
Ferrari approaches the Bahrain Grand Prix, which will take place at Sepang because of the current geopolitical situation, with another proactive development programme. That has been a recurring theme throughout the season, with the team continuing to introduce refinements rather than freezing development of the current car.
The package making its debut in Malaysia will serve two purposes. First, it will act as a test bed for the more substantial upgrade planned for Austin. At the same time, the work is intended to strengthen the technical base on which development of Ferrari’s 2027 car will be built.
The Sepang weekend therefore represents another important stage in the SF-26 programme, alongside the broader technical work being carried out as Ferrari prepares for the 2026 Bahrain Grand Prix at Sepang.
Ferrari modifies underfloor airflow management
More specifically, the updates will focus on airflow management beneath the car, continuing the programme of work that began at Zandvoort. Ferrari will modify the T-tray covering, while the small aerodynamic winglets positioned close to the diffuser will receive a new design.
These changes underline the continuing attention being placed on the lower aerodynamic surfaces of the SF-26, an area that remains central to the car’s overall performance. The latest developments can also be viewed in the context of Ferrari’s wider SF-26 technical development programme during the 2026 season.
Active aero hydraulics also receive an update
The least visible element of the package is also one of the most technically interesting. Ferrari has optimised the hydraulic circuit responsible for controlling the active aerodynamic system at both the front and rear of the SF-26.
The work carried out by the group led by Head of Aerodynamics Diego Tondi has focused primarily on the logic and response of the fluid-management system. Rather than representing a major visible aerodynamic redesign, the change concerns how the hydraulic system responds and manages the active aero mechanisms during operation.
This means the Sepang package combines visible aerodynamic refinements with less obvious work beneath the surface, allowing Ferrari to gather information across several areas before introducing the larger update scheduled for Austin.
Sepang upgrades also support Ferrari’s 2027 development
The importance of the Malaysia package therefore extends beyond the immediate objective of improving the SF-26. Ferrari is using the remaining development programme to validate concepts and working methods that can contribute to the next car, creating a bridge between the current season and the 2027 project.
That longer-term objective is particularly relevant as Ferrari continues to assess the technical challenges that will shape its next Formula 1 car. The team has already been examining how lessons from the SF-26 can influence the technical direction of Ferrari’s 2027 project.
Sepang will therefore provide an important opportunity to evaluate the revised T-tray area, new diffuser-adjacent winglets and updated active-aero hydraulic management before Ferrari moves on to the more extensive package planned for Austin.
