The countdown to the disclosing of Ferrari’s new SF-25 on Wednesday, February 19, has formally began. Ferrari group boss Frederic Vasseur had already confirmed the insights gathered by the Italian web site AutoRacer.it through the growth of mission 677: “Within the fourth yr of this technical cycle, we have now a wealth of information at our disposal, and the 2025 automotive will likely be solely new.” The French Workforce Principal additionally disclosed {that a} mere 1% of the 2024 automotive could be carried over to the SF-25. It is a blunt method of indicating that the 2025 automotive’s growth is akin to ranging from scratch, drawing solely on the in depth information gathered over the previous three seasons. This message was additionally clearly conveyed by Frederic Vasseur to the technical group. The employees, headed by Loic Serra, Ferrari’s new Technical Director, Diego Tondi, accountable for the aerodynamic division, and Fabio Montecchi, the Chief Mission Engineer, has launched daring selections geared toward making the 2025 season not only a transitional yr however a major step ahead earlier than the most important modifications anticipated in 2026.
The SF-25 introduces substantial modifications on the outside, whereas the inside stays much less revolutionary: centered changes to cooling methods are deliberate, however the extremely environment friendly triangular airbox is more likely to keep. The SF-24 was already a car that marked a significant departure from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the outdated 2023 automotive. In response to educated technical sources, “these laws nonetheless have untapped potential,” which means there’s nonetheless appreciable room for enchancment. Whereas this course of is undoubtedly difficult, there’s a consensus that when the proper path is recognized, vital positive aspects can observe. Ferrari’s technique revolves round aggressively adopting the entrance pull-rod, not simply to beat the intense limitations that the SF-24 endured all through the season, notably concerning tire administration. The redistribution of mass, nonetheless, is something however easy and would require time and cautious studying to completely optimize the automotive’s setup.
In distinction to this, the rear part of the SF-25 has not undergone a drastic reconfiguration of its inside mechanics, however somewhat a extra delicate and exact evolution consistent with the group’s aims. Equally, the automotive’s central construction has not skilled an entire overhaul. Whereas different groups, similar to Williams (and others), have opted to redistribute the automotive’s mass, with the FW47 notably eliminating the massive central radiator positioned behind the airscoop, Ferrari has chosen to not undertake such a heavy redistribution of cooling parts. As a substitute, the group has centered on additional optimizing the present cooling setup. This determination maintains the automotive’s authentic character whereas permitting changes that accommodate different modifications, such because the modifications made to the chassis that have an effect on the cooling system structure.
There isn’t any drastic transformation akin to Purple Bull’s 2024 overhaul, which included an in depth redistribution of radiators throughout the RB20, a transfer that, though it posed challenges for the Milton Keynes group, finally helped remedy cooling points, as evidenced by the changes made through the Suzuka race. Ferrari, nonetheless, opted to not take this dangerous method. As a substitute, they selected to retain a well-recognized weight distribution within the central a part of the automotive, staying near the configurations of earlier Ferrari fashions.
As for the SF-25, the 1% of carryover components from the 2024 Formulation 1 automotive, the SF24, as talked about by Frederic Vasseur, will embrace, amongst different issues, the hood consumption, which can preserve its triangular form, mirroring the design of the roll hoop. This characteristic has been part of Ferrari’s design philosophy for the reason that F1-75 in 2022 (and even earlier with the SF-90) and is a part of the group’s want to keep away from shifting in the direction of extra central cooling methods, also called centerline cooling. The distinctive “ears” connected to the perimeters of the airbox may even stay current on the complete fleet of Ferrari-powered vehicles by means of 2024. Even Ferrari’s buyer groups, Sauber and Haas, have opted to centralize their automotive’s mass by shifting not solely the oil radiator to the middle but additionally repositioning the electrical radiator alongside the automotive’s central axis. This enables for higher utilization of house, notably within the sidepod areas.
