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 yr of this technical cycle, we have now a wealth of information at our disposal, and the 2025 automotive will likely be completely 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 improvement is akin to ranging from scratch, drawing completely on the in depth information collected 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, accountable for the aerodynamic division, and Fabio Montecchi, the Chief Venture Engineer, has launched daring choices aimed toward making the 2025 season not only a transitional yr however a major 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: targeted 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 significant departure from Ferrari’s earlier designs, with aerodynamics considerably revamped following the problems confronted by the previous 2023 automotive. In accordance with 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 right path is recognized, vital positive aspects 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, significantly relating to 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 inside mechanics, however quite a extra delicate and exact evolution in step with the crew’s aims. Equally, the automotive’s central construction has not skilled an entire 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 crew has targeted on additional optimizing the present cooling setup. This resolution 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 is no such thing as 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 crew, finally helped clear up cooling points, as evidenced by the changes made throughout the Suzuka race. Ferrari, nevertheless, opted to not take this dangerous method. As an alternative, they selected to retain a well-known 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 System 1 automotive, the SF24, as talked about by Frederic Vasseur, will embody, amongst different issues, the hood consumption, which is able to 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 crew’s want to keep away from transferring in the direction of extra central cooling techniques, also referred to as centerline cooling. The distinctive “ears” hooked up to the perimeters of the airbox will even stay current on all the fleet of Ferrari-powered vehicles via 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 additionally repositioning the electrical radiator alongside the automotive’s central axis. This enables for higher utilization of area, significantly within the sidepod areas.
