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 undertaking 677: “Within the fourth 12 months of this technical cycle, we’ve a wealth of information at our disposal, and the 2025 automotive might be totally new.” The French Staff Principal additionally disclosed {that a} mere 1% of the 2024 automotive can be carried over to the SF-25. It is a blunt means of indicating that the 2025 automotive’s growth is akin to ranging from scratch, drawing totally on the intensive data 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, answerable 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 big step ahead earlier than the main 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 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. Based on educated technical sources, “these laws nonetheless have untapped potential,” that 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 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 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 inner mechanics, however fairly 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, corresponding to Williams (and others), have opted to redistribute the automotive’s mass, with the FW47 notably eliminating the big central radiator situated behind the airscoop, Ferrari has chosen to not undertake such a heavy redistribution of cooling parts. As a substitute, the workforce has centered on additional optimizing the prevailing cooling setup. This choice maintains the automotive’s unique character whereas permitting changes that accommodate different modifications, such because the modifications 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 in depth 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, 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 Method 1 automotive, the SF24, as talked about by Frederic Vasseur, will embody, amongst different issues, the hood consumption, which can keep its triangular form, mirroring the design of the roll hoop. This characteristic 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 workforce’s want to keep away from transferring in direction of extra central cooling methods, also called centerline cooling. The distinctive “ears” hooked up to the perimeters of the airbox may also stay current on your entire fleet of Ferrari-powered vehicles by 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.
