The countdown to the disclosing of Ferrari’s new SF-25 on Wednesday, February 19, has formally began. Ferrari crew boss Frederic Vasseur had already confirmed the insights gathered by the Italian web site AutoRacer.it throughout the improvement 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 can be completely new.” The French Group Principal additionally disclosed {that a} mere 1% of the 2024 automobile can be carried over to the SF-25. It is a blunt approach of indicating that the 2025 automobile’s improvement is akin to ranging from scratch, drawing completely on the intensive data amassed over the previous three seasons. This message was additionally clearly conveyed by Frederic Vasseur to the technical crew. The workers, headed by Loic Serra, Ferrari’s new Technical Director, Diego Tondi, liable for the aerodynamic division, and Fabio Montecchi, the Chief Challenge 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 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 techniques are deliberate, however the extremely environment friendly triangular airbox is more likely to keep. The SF-24 was already a automobile that marked a serious 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from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the outdated 2023 automobile.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 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, nevertheless, is something however easy and would require time and cautious studying to totally 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 moderately a extra refined and exact evolution according to the crew’s aims. Equally, the automobile’s central construction has not skilled a whole overhaul. Whereas different groups, similar to 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 elements. As a substitute, the crew has centered on additional optimizing the prevailing cooling setup. This choice maintains the automobile’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 is no such thing as a 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 crew, in the end helped clear up cooling points, as evidenced by the changes made throughout the Suzuka race. Ferrari, nevertheless, opted to not take this dangerous strategy. 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 parts from the 2024 System 1 automobile, 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 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 crew’s need to keep away from shifting in direction of extra central cooling techniques, also called centerline cooling. The distinctive “ears” hooked up to the perimeters of the airbox may even stay current on all the fleet of Ferrari-powered automobiles by 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 in addition repositioning the electrical radiator alongside the automobile’s central axis. This enables for higher utilization of area, notably within the sidepod areas.
