Ferrari’s three-day check on the Circuit de Catalunya in Barcelona follows intently after the preliminary Fiorano run with the SF-23. Amongst its many aims is the gradual return to motion for each principal drivers, notably Lewis Hamilton’s adaptation to the Scuderia, a program that’s uncommon in comparison with how different drivers sometimes combine into a brand new group. The Spanish check primarily confirms Ferrari’s modified strategy underneath its new technical management, following the late-2024 experiments that spotlight a group seizing each alternative to study instantly on observe.
However let’s take an in depth have a look at how the Italian aspect is targeted on altering its strategy. 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 Automobiles days allowed by rules earlier than the season even begins. One may ask why Ferrari hadn’t finished 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 ground rules, 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 distinct 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 observe experimentation every time doable. Past the Barcelona checks, a key choice in late 2024 was to forego additional upgrades in the course of the Constructors’ Championship battle, as a substitute creating an experimental ground for 2025. This funding allowed Ferrari to enhance stability by means of 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 Observe Testing A concentrate on correlation doesn’t essentially imply that wind tunnel and CFD simulations present incorrect outcomes. Even with the problematic 2023 automobile, Ferrari group 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 group brings one thing to the observe, they observe the anticipated features. He defined that if the wind tunnel predicts a rise of X factors of downforce, the group sees exactly that on observe.
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, affect with asphalt and curbs, in addition to the aerodynamic and mechanical response of the automobile to transients—actions when transitioning between completely different trip heights and postures. All of this impacts drivability, which might solely be correctly assessed in actual situations. The French supervisor defined in 2023 that generally it’s simpler to refine improvements on observe quite than within the wind tunnel. He talked about that there are features of the automobile 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 elements or these not supposed for race use. This was the case with the late-2024 ground, which was by no means utilized in a race apart from an unplanned debut in Qatar, and the identical applies to the Barcelona check with a two-year-old automobile. Even with out testing updates, on-track mileage offers a chance 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 elements on the SF-23 throughout the Spanish checks. The rules prohibit the usage of elements “that present any data associated to the present or earlier championship automobiles,” and permit “solely instruments and sensors obligatory for the automobile’s dependable operation.” Nonetheless, 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 injury and downforce losses, but additionally for aerodynamic evaluation. Furthermore, as of this yr, the rules restrict TPC periods to 4 days and 1,000 km per yr for race drivers, signaling FIA and groups’ consciousness of those checks’ significance for improvement and their effort to stop an escalation.
Past Lewis Hamilton’s adaptation and different work applications, the Barcelona check offers a chance to experiment with numerous setup philosophies, research the automobile’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 underneath the present rules, the place extracting efficiency would require pushing the physics of the automobiles to the restrict, rising the danger of undesirable unwanted effects. Moreover, the Spanish observe is the one which, in each 2023 and 2024, most uncovered Ferrari’s weaknesses, akin to porpoising, a slender working window, poor stability in lengthy high-speed corners, and struggles in medium-speed turns. Between TPC checks and experimental flooring, the Maranello group is adopting a renewed, extra pragmatic and direct strategy than up to now. How worthwhile it will likely be, solely the observe will inform.
