Ferrari 2025: how floor aerodynamics and internal fluid dynamics will differ from SF-24. Ferrari: developments concerning the underbody and the internal fluid dynamics.

During the last few days, we have been gathering news and details about the new Ferrari Formula 1 single-seater for the 2025 championship. After previewing potential updates to the suspension and sidepods, we can now reveal developments concerning the underbody and, particularly, the internal fluid dynamics of what is expected to be called the SF-25, currently known within Ferrari’s racing department as Project 677.

F1 Ferrari 2025: underbody aerodynamics
The car’s underbody is a key element for all single-seaters, especially in modern Formula 1, which relies on ground effect via venturi channels. 2025 will mark the final year of the current regulations, and by now, most teams have learned how to optimize the underbody aerodynamics and the downforce it generates to enhance performance. The days of porpoising troubling drivers on track and engineers in the wind tunnel are long gone.

After facing some difficulties last summer, Ferrari introduced a final version of the underbody, which became the foundation for further evolutionary steps. The underbody set to debut on the new Ferrari car during its first shakedown at the Fiorano circuit and the winter tests in Bahrain will feature a new specification with aerodynamic updates focused on the entry elements of the venturi channels.

Some optimization work will also address the floor edges to generate vortex structures that better seal the car to the ground, consistent with advancements made last year. These modifications were necessary as a consequence of updates to the sidepods.

Internal fluid dynamics
Like the car’s underbody, its internal fluid dynamics is a less visible but highly critical aspect. Inspired by observations from rival teams last year, particularly Red Bull, Ferrari’s technical team established a dedicated group to work on this crucial aspect of Project 677. The main goal was to minimize the intake area of the traditional sidepods, both the horizontal opening and the vertical slot near the chassis, while relocating openings to other areas to cool auxiliary mini radiators.

This may also lead to a redesign of the classic triangular engine air intake, a feature Ferrari has uniquely maintained for years with a compact cross-section. As of now, even though all components of Project 677 have been finalized, there is no confirmed information on the outcome of this work. We may need to wait a few more weeks, or perhaps until the first images of the new single-seater for Lewis Hamilton and Charles Leclerc, set to be unveiled on February 19, the day of the official presentation.
