Ferrari’s three-day take a look at on the Circuit de Catalunya in Barcelona follows intently after the preliminary Fiorano run with the SF-23. Amongst its many targets is the gradual return to motion for each major drivers, notably Lewis Hamilton’s adaptation to the Scuderia, a program that’s uncommon in comparison with how different drivers usually combine into a brand new group. The Spanish take a look at primarily confirms Ferrari’s modified method beneath its new technical management, following the late-2024 experiments that spotlight a group seizing each alternative to be taught straight on monitor.
However let’s take an in depth take a look at how the Italian aspect is concentrated on altering its method. In Barcelona, the Maranello-based group has launched into a three-day testing program, as first reported by the Italian media. Lewis Hamilton and Charles Leclerc are alternating behind the wheel of the SF-23, utilizing up all 4 Testing of Earlier Vehicles days allowed by rules earlier than the season even begins. One may ask why Ferrari hadn’t completed the identical in earlier seasons. A key incentive for utilizing TPC days is the power, beginning in 2025, to run with 2023 automobiles—the primary totally compliant with present flooring rules, which had their edges raised by 15mm after the primary season of ground-effect guidelines to mitigate porpoising. Nevertheless, the first causes lie elsewhere. Ferrari’s winter testing is rooted in a special work technique, formed by new management figures.
Final July, Diego Tondi took cost of the aerodynamics division following Enrico Cardile’s departure, adopted by Loic Serra’s arrival as technical director in October. Since then, Ferrari has proven a extra pragmatic method, emphasizing direct monitor experimentation at any time when potential. Past the Barcelona exams, a key determination in late 2024 was to forego additional upgrades in the midst of the Constructors’ Championship battle, as an alternative creating an experimental flooring for 2025. This funding allowed Ferrari to enhance stability by lengthy, high-speed corners and, extra importantly, to check aerodynamic habits when the ground runs near the asphalt, strengthening the correlation between real-world and digital knowledge.
The Significance of Monitor Testing A give attention to correlation doesn’t essentially imply that wind tunnel and CFD simulations present incorrect outcomes. Even with the problematic 2023 automotive, Ferrari group principal Frederic Vasseur positively commented on the alignment between simulations and real-world efficiency in eventualities replicable within the manufacturing facility. Frederic Vasseur said that when the group brings one thing to the monitor, they observe the anticipated positive factors. He defined that if the wind tunnel predicts a rise of X factors of downforce, the group sees exactly that on monitor.
The problems, frequent to all groups, come up with phenomena that can not be simulated in CFD or the wind tunnel. These embrace sensitivity to porpoising, impression with asphalt and curbs, in addition to the aerodynamic and mechanical response of the automotive to transients—actions when transitioning between completely different journey heights and postures. All of this impacts drivability, which may solely be correctly assessed in actual situations. The French supervisor defined in 2023 that generally it’s simpler to refine improvements on monitor fairly than within the wind tunnel. He talked about that there are elements of the automotive that can not be replicated within the wind tunnel, noting that this wasn’t the case up to now, however with the present floor impact, it’s now.
That is the place the nice benefit of on-track experimentation lies. It’s no coincidence that Ferrari has mitigated current seasons’ points after take a look at classes performed at Zandvoort and Silverstone in 2023 and 2024, respectively. Experiments additionally show helpful even with older parts or these not meant for race use. This was the case with the late-2024 flooring, which was by no means utilized in a race aside from an unplanned debut in Qatar, and the identical applies to the Barcelona take a look at with a two-year-old automotive. Even with out testing updates, on-track mileage gives a possibility to deepen the understanding of physics at play and grasp varied phenomena, data that may be utilized to future developments.
As a TPC session, Ferrari won’t be able to put in any new parts on the SF-23 through the Spanish exams. The rules prohibit the usage of components “that present any data associated to the present or earlier championship automobiles,” and permit “solely instruments and sensors essential for the automotive’s dependable operation.” Nevertheless, this stays a grey space, as strain sensors are all the time current on the ground—not just for security causes, as they assist monitor potential harm and downforce losses, but additionally for aerodynamic evaluation. Furthermore, as of this 12 months, the rules restrict TPC classes to 4 days and 1,000 km per 12 months for race drivers, signaling FIA and groups’ consciousness of those exams’ significance for improvement and their effort to stop an escalation.
Past Lewis Hamilton’s adaptation and different work packages, the Barcelona take a look at gives a possibility to experiment with varied setup philosophies, research the automotive’s responses, and strengthen the understanding of floor impact in eventualities that can not be replicated within the manufacturing facility. This all takes place on the eve of the ultimate season beneath the present rules, the place extracting efficiency would require pushing the physics of the automobiles to the restrict, rising the chance of undesirable unwanted side effects. Moreover, the Spanish monitor is the one which, in each 2023 and 2024, most uncovered Ferrari’s weaknesses, similar to porpoising, a slim working window, poor stability in lengthy high-speed corners, and struggles in medium-speed turns. Between TPC exams and experimental flooring, the Maranello group is adopting a renewed, extra pragmatic and direct method than up to now. How worthwhile will probably be, solely the monitor will inform.
