The countdown to the disclosing of Ferrari’s new SF-25 on Wednesday, February 19, has formally began. Ferrari workforce boss Frederic Vasseur had already confirmed the insights gathered by the Italian web site AutoRacer.it through the growth of challenge 677: “Within the fourth 12 months of this technical cycle, now we have a wealth of information at our disposal, and the 2025 automotive will likely be solely new.” The French Group Principal additionally disclosed {that a} mere 1% of the 2024 automotive can be carried over to the SF-25. This can be a blunt approach of indicating that the 2025 automotive’s growth is akin to ranging from scratch, drawing solely on the in depth information collected over the previous three seasons. This message was additionally clearly conveyed by Frederic Vasseur to the technical workforce. The employees, headed by Loic Serra, Ferrari’s new Technical Director, Diego Tondi, liable for the aerodynamic division, and Fabio Montecchi, the Chief Mission Engineer, has launched daring choices geared toward making the 2025 season not only a transitional 12 months however a major step ahead earlier than the key adjustments anticipated in 2026.
The SF-25 introduces substantial adjustments on the outside, whereas the inside stays much less revolutionary: centered changes to cooling techniques are deliberate, however the extremely environment friendly triangular airbox is prone to keep. The SF-24 was already a car that marked a serious departure from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the previous 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, important positive aspects can comply with. 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, nevertheless, is something however easy and would require time and cautious studying to totally optimize the automotive’s setup.
In distinction to this, the rear part of the SF-25 has not undergone a drastic reconfiguration of its inner mechanics, however quite a extra delicate and exact evolution in keeping with the workforce’s aims. Equally, the automotive’s central construction has not skilled a whole overhaul. Whereas different groups, reminiscent of Williams (and others), have opted to redistribute the automotive’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 elements. As an alternative, the workforce has centered on additional optimizing the prevailing cooling setup. This determination maintains the automotive’s authentic 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 any drastic transformation akin to Pink 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 workforce, in the end 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 an alternative, 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 parts from the 2024 System 1 automotive, the SF24, as talked about by Frederic Vasseur, will embody, amongst different issues, the hood consumption, which is able to keep its triangular form, mirroring the design of the roll hoop. This function 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 workforce’s want to keep away from transferring in direction of extra central cooling techniques, often known as centerline cooling. The distinctive “ears” connected to the perimeters of the airbox can even stay current on your entire fleet of Ferrari-powered vehicles by way 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 in addition repositioning the electrical radiator alongside the automotive’s central axis. This enables for higher utilization of house, notably within the sidepod areas.
