The countdown to the revealing 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 in the course of the improvement of challenge 677: “Within the fourth yr of this technical cycle, we now have a wealth of information at our disposal, and the 2025 automobile shall be solely new.” The French Staff Principal additionally disclosed {that a} mere 1% of the 2024 automobile can be carried over to the SF-25. This can be a blunt means of indicating that the 2025 automobile’s improvement 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 crew. The employees, headed by Loic Serra, Ferrari’s new Technical Director, Diego Tondi, liable 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 yr 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 programs 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from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the outdated 2023 automobile. Based on 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 after the proper path is recognized, important features 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 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 inside mechanics, however slightly a extra delicate and exact evolution according to the crew’s aims. Equally, the automobile’s central construction has not skilled an entire overhaul. Whereas different groups, corresponding to Williams (and others), have opted to redistribute the automobile’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 elements. As a substitute, the crew has centered on additional optimizing the present cooling setup. This resolution 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 structure.
There isn’t a 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 crew, in the end helped clear up cooling points, as evidenced by the changes made in the course of the Suzuka race. Ferrari, nevertheless, 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 automobile, staying near the configurations of earlier Ferrari fashions.
As for the SF-25, the 1% of carryover parts from the 2024 Method 1 automobile, the SF24, as talked about by Frederic Vasseur, will embrace, amongst different issues, the hood consumption, which is able to preserve 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 crew’s need to keep away from shifting in the direction of extra central cooling programs, also called centerline cooling. The distinctive “ears” connected to the perimeters of the airbox may also stay current on the complete fleet of Ferrari-powered vehicles by way of 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 house, notably within the sidepod areas.
