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 venture 677: “Within the fourth 12 months of this technical cycle, we now have a wealth of information at our disposal, and the 2025 automobile will probably be fully new.” The French Workforce Principal additionally disclosed {that a} mere 1% of the 2024 automobile could be carried over to the SF-25. It is a blunt method of indicating that the 2025 automobile’s growth is akin to ranging from scratch, drawing fully on the in depth data gathered over the previous three seasons. This message was additionally clearly conveyed by Frederic Vasseur to the technical group. The workers, headed by Loic Serra, Ferrari’s new Technical Director, Diego Tondi, chargeable for the aerodynamic division, and Fabio Montecchi, the Chief Venture Engineer, has launched daring selections aimed toward making the 2025 season not only a transitional 12 months however a big step ahead earlier than the most important adjustments anticipated in 2026.
The SF-25 introduces substantial adjustments 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from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the outdated 2023 automobile. In response to educated technical sources, “these rules 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 after the proper path is recognized, vital beneficial properties 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 relating to tire administration. The redistribution of mass, nevertheless, is something however easy and would require time and cautious studying to completely optimize the automobile’s setup.
In distinction to this, the rear part of the SF-25 has not undergone a drastic reconfiguration of its inner mechanics, however relatively a extra refined and exact evolution in step with the group’s goals. Equally, the automobile’s central construction has not skilled a whole overhaul. Whereas different groups, reminiscent of Williams (and others), have opted to redistribute the automobile’s mass, with the FW47 notably eliminating the big 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 prevailing cooling setup. This determination maintains the automobile’s unique character whereas permitting changes that accommodate different modifications, such because the adjustments made to the chassis that have an effect on the cooling system format.
There isn’t a drastic transformation akin to Crimson Bull’s 2024 overhaul, which included an intensive redistribution of radiators throughout the RB20, a transfer that, though it posed challenges for the Milton Keynes group, finally helped clear up cooling points, as evidenced by the changes made through the Suzuka race. Ferrari, nevertheless, opted to not take this dangerous method. As a substitute, they selected to retain a well-known weight distribution within the central a part of the automobile, staying near the configurations of earlier Ferrari fashions.
As for the SF-25, the 1% of carryover components from the 2024 Components 1 automobile, the SF24, as talked about by Frederic Vasseur, will embody, amongst different issues, the hood consumption, which can preserve its triangular form, mirroring the design of the roll hoop. This function has been part of Ferrari’s design philosophy because the F1-75 in 2022 (and even earlier with the SF-90) and is a part of the group’s need to keep away from shifting in direction of extra central cooling methods, often known as centerline cooling. The distinctive “ears” connected to the edges of the airbox can even stay current on the complete fleet of Ferrari-powered automobiles via 2024. Even Ferrari’s buyer groups, Sauber and Haas, have opted to centralize their automobile’s mass by shifting not solely the oil radiator to the middle but additionally repositioning the electrical radiator alongside the automobile’s central axis. This permits for higher utilization of area, notably within the sidepod areas.
