Ferrari’s three-day check on the Circuit de Catalunya in Barcelona follows carefully after the preliminary Fiorano run with the SF-23. Amongst its many goals is the gradual return to motion for each major drivers, significantly Lewis Hamilton’s adaptation to the Scuderia, a program that’s uncommon in comparison with how different drivers sometimes combine into a brand new staff. The Spanish check primarily confirms Ferrari’s modified strategy beneath its new technical management, following the late-2024 experiments that spotlight a staff seizing each alternative to study straight on monitor.
However let’s take an in depth have a look at how the Italian facet is targeted on altering its strategy. In Barcelona, the Maranello-based staff 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 Automobiles days allowed by laws earlier than the season even begins. One may ask why Ferrari hadn’t executed 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 absolutely compliant with present flooring laws, which had their edges raised by 15mm after the primary season of ground-effect guidelines to mitigate porpoising. Nonetheless, 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 strategy, emphasizing direct monitor experimentation each time attainable. Past the Barcelona assessments, 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 via lengthy, high-speed corners and, extra importantly, to check aerodynamic conduct when the ground runs near the asphalt, strengthening the correlation between real-world and digital information.
The Significance of Monitor Testing A deal with correlation doesn’t essentially imply that wind tunnel and CFD simulations present incorrect outcomes. Even with the problematic 2023 automotive, Ferrari staff principal Frederic Vasseur positively commented on the alignment between simulations and real-world efficiency in situations replicable within the manufacturing unit. Frederic Vasseur acknowledged that when the staff brings one thing to the monitor, they observe the anticipated positive aspects. He defined that if the wind tunnel predicts a rise of X factors of downforce, the staff sees exactly that on monitor.
The problems, widespread to all groups, come up with phenomena that can not be simulated in CFD or the wind tunnel. These embody 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 totally different trip heights and postures. All of this impacts drivability, which may solely be correctly assessed in actual situations. The French supervisor defined in 2023 that typically it’s simpler to refine improvements on monitor quite 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 good benefit of on-track experimentation lies. It’s no coincidence that Ferrari has mitigated current seasons’ points after check periods carried out at Zandvoort and Silverstone in 2023 and 2024, respectively. Experiments additionally show helpful even with older parts or these not supposed 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 check with a two-year-old automotive. Even with out testing updates, on-track mileage supplies a possibility to deepen the understanding of physics at play and grasp numerous phenomena, information 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 in the course of the Spanish assessments. The laws prohibit using elements “that present any info associated to the present or earlier championship automobiles,” and permit “solely instruments and sensors vital for the automotive’s dependable operation.” Nonetheless, this stays a grey space, as strain sensors are at all times current on the ground—not just for security causes, as they assist monitor potential injury and downforce losses, but in addition for aerodynamic evaluation. Furthermore, as of this yr, the laws restrict TPC periods to 4 days and 1,000 km per yr for race drivers, signaling FIA and groups’ consciousness of those assessments’ significance for growth and their effort to forestall an escalation.
Past Lewis Hamilton’s adaptation and different work applications, the Barcelona check supplies a possibility to experiment with numerous setup philosophies, examine the automotive’s responses, and strengthen the understanding of floor impact in situations that can not be replicated within the manufacturing unit. This all takes place on the eve of the ultimate season beneath the present laws, the place extracting efficiency would require pushing the physics of the automobiles to the restrict, growing the chance of undesirable unintended effects. Moreover, the Spanish monitor is the one which, in each 2023 and 2024, most uncovered Ferrari’s weaknesses, corresponding to porpoising, a slim working window, poor stability in lengthy high-speed corners, and struggles in medium-speed turns. Between TPC assessments and experimental flooring, the Maranello staff is adopting a renewed, extra pragmatic and direct strategy than up to now. How worthwhile will probably be, solely the monitor will inform.
