Scuderia Ferrari heads to Japan for the race weekend on the Suzuka Worldwide Racing Course after the thrilling one-two end on the Albert Park circuit in Australia and the Maranello group not desires to play the straightforward function of a follower within the 2024 Components 1 season. The efficiency delta that the SF-24 automotive at the moment nonetheless has in opposition to the Purple Bull RB20 is the results of numerous components. That is what Ferrari group principal Frederic Vasseur claims. The French supervisor is for certain: the group led by Christian Horner doesn’t have only one single factor able to offering them with the present race tempo benefit, quite we’re speaking about many small particulars that added collectively make the distinction.
Because of this, the Frenchman thinks Ferrari has the potential to “chip away” at efficiency right here and there by optimizing the present bundle of the 2024 Components 1 automotive. A maneuver that, if put into observe with talent, may in truth show efficient. That is the essential thought on which the Maranello group is focusing its most effort forward of the Japanese Grand Prix.
One of many prerogatives at stake considerations measures helpful for tire administration. Ferrari has labored loads on the suspension kinematics, as a way to receive exact dynamic management of the tire. Each motion of the compounds and its subsequent conduct is in truth managed by a sequence of parameters associated to the suspension kinematics. Because of this it’s greater than important to first optimize this space of curiosity. In Components 1, the compound itself is among the most complex fashions to develop and perceive via mathematical calculation.
They had been much more so within the earlier period when the edges had a smaller diameter and the tire deformation was larger. If the three-dimensional motion of the covers just isn’t correctly managed, it’s doable that the ensuing micro-skidding on the observe floor within the three instructions will result in extreme tire overheating. A short dive into the previous, particularly the 2023 Components One season, serves us to recollect how usually the SF-23 was pressured to run on observe with a static camber angle, on common larger than what was seen on the Purple Bull RB19 single-seater. Because of this the interior shoulder of the compound tended to overheat excessively.
The second path in direction of which the Prancing Horse has labored and continues to be working considerations the administration of the automotive on the observe. On this entrance, Frederic Vasseur acknowledged that in the intervening time the pink automotive just isn’t but capable of totally exploit the complete out there potential of the automotive. Between the Bahrain Grand Prix and the Australian Grand Prix, the Maranello group made the utmost effort to increase the lifetime of the compounds as a lot as doable. To do that, they intervened on the so-called “warm-up technique.” A Components 1 tire warms up due to a hysteresis course of, which implies the attribute of a system in reacting to utilized stresses.

F1 | Ferrari: SF-24 takes care of the warm-up technique. “Sluggish introduction” key for lengthy sturdiness
Through the first laps of the primary 2024 World Championship race, which was held on the Sakhir circuit, we nonetheless keep in mind how Charles Leclerc pushed exhausting to attempt to sustain with the Purple Bull of Max Verstappen. In doing so, the tyre administration was severely compromised, as the mandatory and likewise requested “gradual introduction” at the start of a brand new stint was not current. On this explicit section, the compound continues to be chilly. The grip is subsequently not but exploitable and slipping in cornering phases is most, a scenario that, as we are able to think about, creates then irreparable harm to the tyres. That’s why, merely, the perfect tactic that can be utilized considerations the gradual activation in direction of the right temperature window.
Clearly, throughout a Components 1 race, you can’t do a gradual out-lap like in qualifying, the place the warm-up technique may be managed with out the fear of getting to test the rearview mirrors. It’s essential to pay a number of consideration particularly within the areas of the observe outlined as “strategic”, the place the stresses on the tire are most. Moreover, the 4 tires should enter the right working window concurrently, so as to not enable the creation of pointless imbalances that result in untimely put on.
We mentioned that to hit the tire utilization window, a exact hysteresis cycle have to be adopted. A transparent context that’s outlined throughout the first free observe classes, via the traditional course of that entails comparative assessments on totally different settings, adopted by fine-tuning primarily based on the collected knowledge. It’s then understood which curves may be tackled on the most out there efficiency and quite the opposite, these the place administration is required, primarily based on the structure of the observe to optimize the activation of the tires.
F1 | Ferrari SF-24: “further aids” decisive
Let’s make an instance to higher perceive the scenario. In Australia, on the Albert Park circuit, the part of the observe the place Charles Leclerc was requested for extra correct “tyre-management” was flip 12. On the identical time, the Monegasque driver sought to discover a right mixture between static stability in braking, the so-called “brake migration” and the differential lock for every nook of the observe. Changes that may be made instantly by way of the paddles on the steering wheel that help you load or unload an axle throughout the passage of a nook.
We’re speaking about “corrections” in sure pre-mapped circumstances due to the usage of small toggles, levers positioned on the rear a part of the steering wheel that, along with offering right stability, are capable of improve or lower the contribution of power enter on the tires. We’re speaking about “further aids”, a exact job that must be put into observe particularly after the pit cease throughout the first kilometers of the tire’s life, to range the settings of the aforementioned parameters to strategically shift the burden on the 2 axes of the automotive. An efficient measure that’s rising tire administration whereas closing the hole on the Purple Bull RB20 within the race.
Additionally due to a number of research carried out throughout the winter, the Scuderia Ferrari technicians have managed to enhance the administration of the compounds, whereas ready for the key aerodynamic updates deliberate for the Imola Grand Prix, the primary substantial bundle of the 2024 Components 1 season for the SF-24 automotive as a way to present an additional step ahead when it comes to tire administration. Then again, as emphasised by Frederic Vasseur himself, it’s time to take dangers, in a managed method, to optimize the technical materials out there as a result of though Purple Bull continues to take pleasure in a sure hole in its favor estimated by the Maranello itself at about 3/4 tenths, the will of the Italian group to struggle for essential targets this 12 months is keen.
