Lewis Hamilton’s first Ferrari has lastly come to mild, and with it, the anticipation grows to see it compete on monitor towards Crimson Bull, McLaren and Mercedes. The brand new Ferrari single-seater, developed beneath the shut scrutiny of Technical Director Loic Serra, who joined mid-2024, and Ferrari crew principal Frederic Vasseur, is able to struggle for each Method 1 titles within the 2025 championship. With expectations rising and the drivers extremely motivated, let’s discover the improvements aboard the Ferrari SF-25 in comparison with final 12 months’s SF-24, which got here very near successful the Constructors’ title.
The one-seater pushed by Lewis Hamilton and Charles Leclerc has undergone a radical transformation, significantly from a technical standpoint. Challenge 677, known as upon to compete for the world championship, has chosen to revolutionize its entrance suspension idea by adopting the pull-rod system. The setup is now a double pull-rod, with the entrance that includes a rigorously organized arm configuration.

The higher wishbone doesn’t undertake an excessive anti-dive setup like McLaren and Crimson Bull however takes a barely extra conservative strategy. The explanations behind this technical alternative might differ and be linked to each aerodynamics and mechanics. The brand new configuration and positioning of the assorted arms permit for an airflow channel in direction of the undercut and the brand new radiator inlets. Moreover, the brand new pull suspension rod, in addition to being thinner, directs the airflow within the central space of the automotive.
The central part of the single-seater has been considerably refined, showing extra tapered and sinuous in comparison with the SF-24. Ranging from the inlet, the SF-25 automotive now has a extra pronounced higher lip to higher separate the airflow directed in direction of the undercut from that flowing above the sidepods. The higher lip is now extremely refined, that includes a mirror housing with a double shell for micro-aerodynamic functions. On this space, the Ferrari technicians and engineers have additionally added a micro-aero element that generates a vortex to guard the airflow passing over the sidepod ramp.
Advanced and shorter rear finish for more room on the ground

The rear part of the SF-25 has undergone quite a few modifications, with intensive optimization and refinement of the mechanics. The rear suspension, revolutionized within the 2024 Method 1 season, now has an much more compact housing and a revised positioning of the arms. The response strut, typical of the pull-rod system, has now been moved a couple of millimeters towards the rear. This has allowed the SF-25 to realize effectivity and enhance airflow cleanliness in that space.
A much less seen however nonetheless vital innovation on the SF-25 is the brand new association of the sidepods in relation to the automotive’s flooring. The ground has been prolonged by a couple of millimeters together with the wheelbase, confirming the data which has lately been reported by F1inGenerale in one in every of their unique protection a couple of weeks in the past. With extra maneuvering house, the Maranello crew has been capable of refine the 3D geometry of the ground and its means to generate downforce at each high and low speeds. Moreover, an extended wheelbase gives higher stability in medium to high-speed long-radius corners.
The sidepods at the moment are shorter and extra compact to create more room for the facility unit’s radiators and all auxiliary techniques, corresponding to hydraulics. To keep up effectivity and, most significantly, reliability, Enrico Gualtieri’s energy unit division has relocated some cooling components to the engine cowl. This variation is seen via the brand new form of the quilt, which is now extra prolonged and includes a smaller fin in comparison with the SF-24. The relocation of elements can be justified by the presence of some vents on the rear of the engine cowl and close to the driving force’s race quantity.
