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, 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 crew. The Spanish check primarily confirms Ferrari’s modified strategy underneath its new technical management, following the late-2024 experiments that spotlight a crew seizing each alternative to study straight on observe.
However let’s take an in depth take a look at how the Italian facet is targeted on altering its strategy. In Barcelona, the Maranello-based crew 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 would possibly ask why Ferrari hadn’t carried out 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 totally 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 at any time when attainable. Past the Barcelona checks, a key choice in late 2024 was to forego additional upgrades in the midst of the Constructors’ Championship battle, as an alternative creating an experimental ground for 2025. This funding allowed Ferrari to enhance stability via lengthy, high-speed corners and, extra importantly, to review aerodynamic conduct 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 automobile, Ferrari crew principal Frederic Vasseur positively commented on the alignment between simulations and real-world efficiency in situations replicable within the manufacturing facility. Frederic Vasseur said that when the crew 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 crew sees exactly that on observe.
The problems, widespread to all groups, come up with phenomena that can’t be simulated in CFD or the wind tunnel. These embody sensitivity to porpoising, influence 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 circumstances. The French supervisor defined in 2023 that typically it’s simpler to refine improvements on observe somewhat than within the wind tunnel. He talked about that there are features of the automobile that can’t be replicated within the wind tunnel, noting that this wasn’t the case prior 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 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 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 gives a chance 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 will be unable to put in any new parts on the SF-23 in the course of the Spanish checks. The rules prohibit using elements “that present any data associated to the present or earlier championship vehicles,” and permit “solely instruments and sensors essential for the automobile’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 injury 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 checks’ significance for growth and their effort to forestall an escalation.
Past Lewis Hamilton’s adaptation and different work applications, the Barcelona check gives a chance to experiment with numerous setup philosophies, research the automobile’s responses, and strengthen the understanding of floor impact in situations that can’t be replicated within the manufacturing facility. 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 vehicles to the restrict, rising the danger of undesirable negative effects. Moreover, the Spanish observe is the one which, in each 2023 and 2024, most uncovered Ferrari’s weaknesses, similar 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 crew is adopting a renewed, extra pragmatic and direct strategy than prior to now. How worthwhile it will likely be, solely the observe will inform.
