Ferrari’s three-day take a look at on the Circuit de Catalunya in Barcelona follows carefully after the preliminary Fiorano run with the SF-23. Amongst its many aims is the gradual return to motion for each most important drivers, significantly Lewis Hamilton’s adaptation to the Scuderia, a program that’s uncommon in comparison with how different drivers usually combine into a brand new staff. The Spanish take a look at 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 observe.
However let’s take an in depth take a look at how the Italian aspect 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 Vehicles days allowed by rules earlier than the season even begins. One may ask why Ferrari hadn’t accomplished the identical in earlier seasons. A key incentive for utilizing TPC days is the flexibility, beginning in 2025, to run with 2023 vehicles—the primary absolutely compliant with present ground 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 strategy, emphasizing direct observe experimentation each time doable. Past the Barcelona exams, a key determination in late 2024 was to forego additional upgrades in the course of the Constructors’ Championship battle, as an alternative growing an experimental ground for 2025. This funding allowed Ferrari to enhance stability by way 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 knowledge.
The Significance of Observe 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 staff principal Frederic Vasseur positively commented on the alignment between simulations and real-world efficiency in eventualities replicable within the manufacturing unit. Frederic Vasseur acknowledged that when the staff 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 staff sees exactly that on observe.
The problems, frequent to all groups, come up with phenomena that can’t be simulated in CFD or the wind tunnel. These embrace sensitivity to porpoising, affect with asphalt and curbs, in addition to the aerodynamic and mechanical response of the automotive to transients—actions when transitioning between totally different experience heights and postures. All of this impacts drivability, which may solely be correctly assessed in actual circumstances. The French supervisor defined in 2023 that generally it’s simpler to refine improvements on observe reasonably than within the wind tunnel. He talked about that there are features of the automotive that can’t be replicated within the wind tunnel, noting that this wasn’t the case previously, 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 latest seasons’ points after take a look at periods performed 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 take a look at with a two-year-old automotive. Even with out testing updates, on-track mileage offers a possibility to deepen the understanding of physics at play and grasp numerous phenomena, data 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 exams. The rules prohibit using elements “that present any data associated to the present or earlier championship vehicles,” and permit “solely instruments and sensors obligatory for the automotive’s dependable operation.” Nevertheless, this stays a grey space, as stress sensors are at all times current on the ground—not just for security causes, as they assist monitor potential harm and downforce losses, but in addition for aerodynamic evaluation. Furthermore, as of this 12 months, the rules restrict TPC periods to 4 days and 1,000 km per 12 months for race drivers, signaling FIA and groups’ consciousness of those exams’ significance for growth and their effort to forestall an escalation.
Past Lewis Hamilton’s adaptation and different work packages, the Barcelona take a look at offers a possibility to experiment with numerous setup philosophies, research the automotive’s responses, and strengthen the understanding of floor impact in eventualities that can’t be replicated within the manufacturing unit. 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 vehicles to the restrict, rising the chance of undesirable uncomfortable side effects. Moreover, the Spanish observe is the one which, in each 2023 and 2024, most uncovered Ferrari’s weaknesses, reminiscent of porpoising, a slender working window, poor stability in lengthy high-speed corners, and struggles in medium-speed turns. Between TPC exams and experimental flooring, the Maranello staff is adopting a renewed, extra pragmatic and direct strategy than previously. How worthwhile it will likely be, solely the observe will inform.
