Ferrari bets on new Floor to Fix SF-25: All the upgrades explained – F1 Tech Bahrain GP

Ferrari’s hopes for the SF-25 rely on the new Bahrain floor, with hidden details and fresh concepts aiming to “unlock” the car’s potential

After three rounds with few encouraging results – excluding the Sprint in China – Ferrari is determined to unlock the SF-25. The first upgrade package makes its debut at the Sahkir circuit, a crucial venue for comparing data with the “baseline” version of the 677. The new Ferrari floor, debuting in Bahrain, features notable innovations and concepts borrowed from rival cars, offering key insights into Ferrari’s latest iteration.

This initial update package marks a pivotal step for the Maranello-based squad. It’s the first evolution stemming from development work that began in late 2024, when the team started outlining the upgrade path for the 677. Alongside this first evolutionary step, the Scuderia plans to complete the full floor package in due course.

This component will be key to greenlighting the second phase of development, arriving at a critical point in F1 history, right on the edge of a regulatory transformation.

Small details for a greater goal

The latest SF-25 spec features several targeted changes aimed at managing airflow vortices more effectively. Ferrari’s aero department has worked on multiple areas of the floor—both the floor edge and the underside.

The most significant change is around the floor edge and the fences at the Venturi inlet. A series of micro-adjustments aim to energize the sealing vortices that prevent dirty airflow from disrupting the floor. The outermost fence now has a stepped profile instead of a linear one, likely to redirect airflow more precisely along the floor edge. Meanwhile, the inner fence has been extended, allowing for more refined vortex control in that area.

In parallel with the new floor fences, Diego Tondi’s aero team has refined the floor edge architecture—a key performance area in this generation of ground-effect cars, where the Floor Edge Wing plays a central role.

As expected, the most visible change lies in the winglet zone, where Ferrari has introduced a new vortex generator. The structure has also been redesigned to energize the sealing flow more effectively. With this larger setup, the SF-25 now appears capable of operating at higher ride heights than originally designed.

That’s an important gain for this early part of the season, especially for a car that still seems forced to run in a “crossover mode”.

Crucial updates to the SF-25 diffuser spotted in Bahrain

Following changes to the Floor Edge Wing, Ferrari’s aerodynamicists have also made significant modifications to the SF-25’s diffuser. The new specification appears to draw directly from the version seen on the SF-24 in Monza.

The diffuser keel has been narrowed and its flanks reshaped to better manage pressure recovery underneath the floor. These changes aim to expand the available airflow volume.

This is vital to prevent instability during pressure recovery at the floor exit, where airflow must transition cleanly into the beam wing region. External wing elements now benefit from reduced flexing, allowing for more stable and consistent airflow exiting the floor, resulting in more reliable downforce.

Ferrari’s hopes rest on this updated spec, though—as noted yesterday—a new floor alone won’t solve all the SF-25’s deeper issues.
