Lewis Hamilton’s first Ferrari has lastly come to mild, and with it, the anticipation grows to see it compete on observe in opposition to Purple Bull, McLaren and Mercedes. The brand new Ferrari single-seater, developed below the shut scrutiny of Technical Director Loic Serra, who joined mid-2024, and Ferrari workforce principal Frederic Vasseur, is able to struggle for each Formulation 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 yr’s SF-24, which got here very near successful the Constructors’ title.
The only-seater pushed by Lewis Hamilton and Charles Leclerc has undergone a radical transformation, notably from a technical standpoint. Challenge 677, referred to 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 fastidiously organized arm configuration.

The higher wishbone doesn’t undertake an excessive anti-dive setup like McLaren and Purple Bull however takes a barely extra conservative strategy. The explanations behind this technical selection may range and be linked to each aerodynamics and mechanics. The brand new configuration and positioning of the varied arms enable for an airflow channel in direction of the undercut and the brand new radiator inlets. Moreover, the brand new pull suspension rod, apart from 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 raised 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 in depth optimization and refinement of the mechanics. The rear suspension, revolutionized within the 2024 Formulation 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 just a few millimeters towards the rear. This has allowed the SF-25 to achieve 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 just a few millimeters together with the wheelbase, confirming the knowledge which has just lately been reported by F1inGenerale in one in every of their unique protection just a few weeks in the past. With extra maneuvering area, the Maranello workforce has been capable of refine the 3D geometry of the ground and its skill to generate downforce at each high and low speeds. Moreover, an extended wheelbase gives larger 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 ability unit’s radiators and all auxiliary methods, equivalent to hydraulics. To take care of effectivity and, most significantly, reliability, Enrico Gualtieri’s energy unit division has relocated some cooling parts to the engine cowl. This modification is seen via the brand new form of the quilt, which is now extra prolonged and incorporates 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.
