On the first day of the second Bahrain test session, the Ferrari SF-26 revealed a very interesting technical update at the rear: a completely new aerodynamic element placed immediately behind the exhaust. This detail is not isolated but part of a clear overall design philosophy, confirming what had already been noted earlier: the SF-26 stands out especially at the rear.
Looking at the car as a whole, a distinct philosophy emerges. The front is relatively conservative, certainly less aggressive than cars like the McLaren, followed by a highly worked central section and an extremely sophisticated rear. The true identity of the SF-26 is concentrated in the floor and rear end, based on what has been seen on track so far, and this is unlikely to change drastically before Melbourne. The new element behind the exhaust, debuting on the first day of the second test session, reinforces this reading.
The diffuser’s architecture already highlighted a near-obsessive search for efficiency in extracting airflow. With the addition of this new profile, Ferrari adds another layer of control over hot gas flow and its interaction with the exhaust, particularly relevant this year given the more energetic gases due to the absence of the MGU-H and the rear wing. Importantly, this solution had to wait for an extensive FIA approval, as it was considered borderline—a very aggressive interpretation of the technical regulations regarding the volumes used. Ferrari wanted to use it to surgically control the quality of the flow exiting the diffuser. It is a fine but ambitious piece of work.
Another notable aspect is how Ferrari managed this first day of testing. The team changed the lineup at the last minute, following the FIA’s approval of the new rear solution. Both Charles Leclerc and Lewis Hamilton were given the chance to test the updates on the same day. These updates also include a new engine cover with a smaller exhaust outlet at the rear and two openings at the front, similar to the SF-25. This choice was deliberate, as collecting feedback from both drivers on the same day allows for a more insightful evening debrief and better optimization of work in the following days.
This approach aligns perfectly with what Charles Leclerc had mentioned in previous days, stating that Ferrari’s pre-season program has been planned and is being managed in a much more efficient and less complicated way compared to last year.
As the Scuderia moves through its Bahrain program, the focus remains on extracting every millisecond from this ambitious aerodynamic package. By securing FIA approval for their most complex components early, Maranello has ensured that the SF-26 heads to the season opener with a validated technical foundation. Whether these sophisticated rear-end solutions will provide the definitive edge over their rivals is the central question as the 2026 season draws near, but the early signs suggest a team operating with newfound confidence and precision.
The Ferrari SF-26 has therefore introduced a highly sophisticated rear aerodynamic profile following a lengthy FIA approval process, allowing both Charles Leclerc and Lewis Hamilton to provide immediate feedback on the aggressive new design during Bahrain testing.
