Within the 2024 Formulation 1 season, Ferrari has proven simple progress. In comparison with the earlier championship, the SF-24 single-seater has resolved some points that emerged with its predecessor and managed to win as many as 5 races. From the one Singapore occasion in 2023 to a quintet, specifically Australia, Monaco, Italy, USA, Mexico, that just about allowed the Prancing Horse crew to safe a constructors’ title, which might have been astonishing.
Over the course of a single season, the Italian crew moved from third to second place within the constructors’ standings, overtaking Mercedes and, most significantly, Crimson Bull, which had appeared unattainable to everybody till the second a part of 2024. This development now must be confirmed and solidified. Many inventions will characterize Mission 677, which is the inner code for the Maranello crew’s 2025 Formulation 1 automobile, improvements which have not too long ago been confirmed by Ferrari crew principal Frederic Vasseur himself, however there may be one space particularly which will obtain particular consideration: the brakes.
The technical battle between Maranello and Woking in 2024 additionally performed out on this entrance and it’s value mentioning that the Ferrari SF-24 had a a lot less complicated brake configuration in comparison with McLaren MCL38. Within the Mexico Metropolis Grand Prix, essentially the most difficult of the complete championship for cooling because of the skinny air, important variations emerged. Although Ferrari received the race on the on the Autódromo Hermanos Rodríguez, McLaren appeared much less troubled. It appears paradoxical, however that’s the way it was. Let’s rewind the tape.
The Ferrari engineers and technicians had opted for an aggressive configuration of the brake duct inlets, with a extra pronounced narrowing of the opening, betting on the power to run in clear air. We recall that Carlos Sainz began from pole place and Charles Leclerc from fourth place.
The technique labored for the Spaniard, who, as soon as he overtook Max Verstappen, which was faster off the road, sped towards victory. Charles Leclerc was additionally performing effectively in second place, however lapped visitors within the last phases negatively impacted the strategic plan, permitting Lando Norris to catch up and overtake, benefiting from a mistake by the Monegasque driver which was battling brake temperatures.
Charles Leclerc’s points had already begun within the early phases of the Mexico Metropolis Grand Prix. When the Monegasque driver was lower than two seconds behind his Maranello teammate, the brake caliper temperatures started rising alarmingly. This necessitated the usage of the lift-and-coast method, a necessity magnified and misunderstood within the scattered post-race social commentary.
The technical battle on that event between the 2 championship-leading groups targeted on brake cooling, an space the place McLaren outperformed Ferrari, regardless of the Mexican Grand Prix being received by the SF-24 automobile of Carlos Sainz. Andrea Stella, crew principal of the Woking crew (and likewise an engineer, it’s value noting), praised his technical workers for designing and producing the brand new brake cooling parts in time for the Mexican Grand Prix.
The Italian supervisor, who was additionally a part of the Ferrari F1 crew for greater than a decade, between 2000 and 2015, emphasised that, because of the brand new parts, the difficulty of “cooling” was by no means a priority for McLaren throughout the Mexican weekend, permitting for wonderful cooling ranges with out compromising aerodynamic effectivity.
The McLaren MCL38 and the Ferrari SF-24 due to this fact had two completely different approaches to brake cooling. The brake caliper cooling system of the papaya-colored automobile includes a bigger air consumption in comparison with its purple counterpart. Furthermore, on the MCL38, the ducts break up right into a “dual-headed” cooling channel. This part, amongst different issues, is manufactured from carbon fiber, whereas Ferrari’s is aluminum. Carbon fiber is extra thermally manageable, because it conducts much less warmth than metals, together with aluminum.
In Mexico Metropolis, Ferrari’s system, less complicated in design regardless of the addition of extra holes on the discs, didn’t dissipate warmth successfully throughout stress phases, akin to throughout the late lapping maneuvers Charles Leclerc needed to carry out. This induced overheating, contributing to the Monegasque driver’s error, which Lando Norris capitalized on. Projecting this distinction onto the overall conduct of the 2 vehicles, one would possibly speculate, with out claiming to disclose technical insights via easy logical reasoning, that the occasional problem the SF-24 had in managing the tire’s thermal window was partly as a consequence of this issue. Over the 2024 Formulation 1 championship, McLaren was extra according to the Pirelli tires, inflicting much less stress and adapting higher to assorted situations. Ferrari, against this, encountered severe challenges when air and observe temperatures fell beneath a sure threshold.
The warmth dissipated by the brakes is a key think about controlling tire temperature, and it’s seemingly that McLaren’s extra complicated system, mixed with the usage of composite supplies, resulted in much less sensitivity to thermal fluctuations, finally benefiting constant efficiency and decreasing tire thermal degradation.
Ferrari delivered true masterclasses in compound administration, as seen within the Italian Grand Prix on the Monza circuit, but additionally confronted important struggles in different eventualities, akin to in Canada or Brazil. These races, supporting the argument, had been run in moist situations and low temperatures.
The automobile to be entrusted to Lewis Hamilton and Charles Leclerc will characteristic over 90% new elements, in line with Fred Vasseur. This was introduced sensationally, although it’s fairly regular even beneath a regulatory framework of continuity.
Among the many updates will seemingly be a brand new design for the brake air intakes, inside fluid dynamics, and ducts for dissipating scorching air. Aluminum is anticipated to get replaced by carbon, which is lighter (a serious benefit in steadiness, contemplating it includes unsprung plenty) and, most significantly, offers extra constant thermal responses, avoiding the fluctuations that negatively influence tires.
These components have an effect on thermal degradation and likewise hysteresis, the tire’s capability to deform and return to its authentic form. Having a extra responsive “shoe” on this respect is of significant significance. Callum Frith, head of the tire division, has pushed to attain extra constant situations for establishing simpler pit exit procedures, with which Leclerc, particularly, struggled final season.
Exactly as a result of there shall be no regulatory modifications between 2024 and 2025, Ferrari needs to deal with refining particulars to intentionally intention for each titles. The second half of the final season demonstrated that Maranello has the whole lot it takes to compete. The Prancing Horse is severe about producing a much less “moody” automobile, much less depending on environmental situations.
