Ferrari’s extended diffuser catches rival attention
The SF26 stands out for its extended diffuser, a solution that has already caught the attention of rival teams. The first open-track testing session provides ample photographic coverage of the new cars, revealing details that had remained hidden in recent weeks. Ferrari, in particular, has showcased a very distinctive diffuser, already drawing the curiosity of competitors. Meanwhile, the first development package is awaited, with the SF26 expected to evolve before its competitive debut in Melbourne.
The SF26 diffuser
From Bahrain come the first images of the rear of the new Ferrari, highlighting the diffuser solution. At Maranello, engineers carefully interpreted the regulations, exploiting the available volumes to extend the extractor. Two small central extensions climb along the sides of the rear impact structure. This geometry helps enhance the extraction of airflow from the diffuser, increasing the downforce generated by the floor. Furthermore, the appendages are positioned closer to the upper rear wing, making them more sensitive to the opening of the movable profiles on the straights.
The SF26 rear has piqued the interest of competitors since the Barcelona tests. Mercedes also employs a similar geometry, although less elaborate than Ferrari’s. Structurally, replicating this solution does not appear difficult—it essentially involves adding two carbon flaps—but making it work is another challenge. In aerodynamics, every component interacts with others, even those far apart, so it remains to be seen what adjustments are necessary to optimize the extended diffuser.
Other points of interest
Photos of the SF26 running in Bahrain also reveal another solution previously glimpsed in the Fiorano shakedown and later in Barcelona. These are the side radiator openings, shaped lower down and tapering near the chassis. This area is important not only for cooling efficiency but also for channeling airflow under the sidepods and pressurizing the space around the cockpit, creating a high-pressure zone that helps repel wheel-induced turbulence.
Finally, the three-quarter rear view provides a fresh perspective on the multi-link front suspension, with the steering mechanism positioned between the two lower elements, similar to the McLaren 2025 design. Ferrari’s design in this area is noticeably more aggressive than in recent years, tilting the upper triangle to guide airflow from the front wing. However, it is also evident that the SF26’s front-end is less advanced than its direct rivals, particularly regarding the rearward upper arm, which is not as elongated as on competing cars. Nevertheless, Ferrari’s car contains several areas of interest, leaving fans and engineers eager to evaluate the updates that will arrive with the forthcoming development package.
The SF-26 therefore stands out as a sophisticated blend of aggressive innovation and calculated refinement. While rivals Mercedes and Red Bull look to counter with their own technical updates, the focus on rear-end efficiency and sidepod management suggests that Ferrari is prioritizing a stable aerodynamic platform to take on the radical challenges of the new 2026 Formula 1 era.
