Ferrari is combating for the F1 Constructors’ Championship, a two-way battle with McLaren. With two Grands Prix remaining within the season, together with a Dash Race in Qatar—a circuit that would show difficult for the Scuderia—the staff should regroup and place itself to carry out at its finest. It is a dedication they owe to themselves and their followers. The title has been absent for the reason that 2008 season, when the mixed factors of Massa and Raikkonen surpassed these of Kovalainen and Hamilton.
Ferrari isn’t experiencing a straightforward second. The present driver pairing, which has labored nicely over 4 years, appears to be nearing its finish. Rumors recommend that they not tolerate one another and that their relationship has reached all-time low. Through the years, misunderstandings have occurred, however disputes have at all times been resolved internally, leaving no important aftermath. Sainz will go away the staff on the finish of the 12 months, making manner for seven-time world champion Lewis Hamilton.
Subsequent 12 months, Sainz will take the wheel of Williams, a staff experiencing important development however nonetheless removed from the highest. For that reason, regardless of his professionalism, Carlos is racing for Ferrari but in addition for himself. And there’s nothing fallacious with that, let’s be clear. At present, to ease the stress, we analyze a state of affairs involving tire administration throughout the third stint of the race—a aggressive state of affairs the place the 2 SF-24s delivered their finest efficiency.
F1, Las Vegas GP: Ferrari and the activation of the Onerous tire with the SF-24
After the race, it was defined how Ferrari “understood” solely throughout the last stint handle the compounds successfully. This permits us to clarify how the Italian staff reached this understanding concerning the Onerous compound and what was virtually essential to optimize so-called “tire administration.” Let’s start with lap 28, the final lap earlier than Carlos Sainz’s second pit cease, the place the Spaniard was getting ready to modify to a second set of white-banded Pirellis—a compound that carried out considerably higher on the SF-24 in comparison with the Mediums.
We observe the dashboard structure, faithfully reproduced primarily based on Ferrari’s steering wheel. Along with the assorted sections of the principle window, our main curiosity lies within the 4 packing containers surrounding the phrase GEAR (gear). Inside these rectangles are numbers indicating the temperature delta of every tire, each entrance and rear, relative to the goal set by the staff. This gives concrete information on how far every tire is from the optimum temperature outlined by the staff. It’s necessary to notice that every staff could have barely totally different targets primarily based on their expertise with the automotive.
Towards the tip of the second stint on the Onerous tires, Sainz enters the pit lane with the entrance left tire exhibiting an in-line studying, because the distinction from the goal is zero (“0”). In the meantime, the entrance proper tire is 3°C beneath the optimum temperature. This means that the tire is colder, with a smaller portion of the tread deforming and struggling to generate warmth. The rear axle, alternatively, is 3°C above the goal for each tires. Sainz then switches to the second set of white-banded Pirellis. Firstly of the stint, the temperatures are nicely beneath the best vary.
The picture above serves as proof. Within the tire blankets, as per the rules established by the Worldwide Federation, the utmost temperature can’t exceed 70°C. Moreover, when the tires are eliminated and positioned by the mechanics on the mat in entrance of the storage, ready for the automotive to reach, the tires naturally lose a few of the temperature beforehand attained on account of ambient circumstances. Moreover, touring by the pit lane at lowered pace—60 km/h within the 2024 season—causes the tires to chill additional.
When an F1 automotive leaves the pit lane and begins pushing, the temperature throughout the 4 tires could be thought of comparatively homogeneous. The truth is, we see that Carlos Sainz’s Ferrari No. 55 reveals values roughly 30°C beneath the “splendid” goal on each axles. It ought to be specified that this refers back to the “floor temperature,” that means the tread, and never the interior carcass values, that are additionally monitored by way of particular sensors. Wanting on the subsequent picture, we are able to confirm the info on the finish of the outlap.
On the finish of the primary lap after rejoining the monitor following the tire change, the state of affairs is as displayed on the dashboard above. We’re at lap 30. Whereas the temperatures start to rise, they continue to be removed from the best values wanted to correctly exploit the tires. The front-right tire is the closest to the required worth, as it’s the most confused among the many 4, given the circuit’s structure. The Spaniard performs a single “introduction,” a transfer that barely delays activation however ensures the estimated helpful lifetime of the tire.
For that reason, he tries to be cautious throughout acceleration phases, because the entrance axle is less complicated to carry to temperature. The pit wall, by way of race engineer Riccardo Adami, units a lap time goal of 37.5 seconds. Nevertheless, it’s famous that the Ferrari driver finally ends up barely sooner than required, decreasing the lap time by about two-tenths in comparison with the goal set by the pit wall, which is carefully linked to the distant storage offering all the required information to guage each issue and carry out successfully.
Wanting on the subsequent picture, we discover improved temperatures within the subsequent lap. Essentially the most difficult operation includes activating the front-left tire, which stays persistently colder than the best tire on the identical axle. Sainz and Adami subsequently agree to attenuate the steering angle in gradual corners to assist heat up the whole entrance finish of the Ferrari, as was accomplished final season. This system isn’t simple to execute however proves extremely efficient, concurrently avoiding extreme stress on the rear tires.
To take care of management of the rear finish, Sainz employs “energy administration” in particular corners, equivalent to Flip 6, aiming to protect the entrance from graining. Graining happens when the entrance tires are too chilly and slide excessively, making a layer of abraded rubber on the tread’s floor, decreasing total grip. To stop this, the entrance axle should be saved as shut as potential to the best temperature. The purpose is to stabilize the temperatures across the goal worth.
By lap 32, Sainz has skillfully introduced all 4 tires as much as temperature in a gradual and simulated method. This method not solely extends tire life but in addition stabilizes the floor temperature, permitting the tires to realize optimum grip. Within the chilly circumstances of Las Vegas, the compounds have a tendency to chill, dropping as much as 4–5°C on the straights. The front-left tire has practically the identical temperature because the rear tires, which avoids activation asynchrony, a frequent challenge in tire administration.
Transferring to lap 40, close to the tip of the stint, Riccardo Adami radios in to congratulate Sainz. He commends the Spaniard’s efficiency, which was considerably higher than throughout the second stint, the place tire administration was removed from splendid. Moreover, the Italian race engineer advises in opposition to reaching the tires’ saturation level in Flip 7, a measure meant to stop overheating.
Contemplating the structure of the nook, a medium-speed left-hander, the Ferrari’s technique, developed with the pit wall, aimed to cut back the SF-24’s pace on entry. The reason being easy: to keep away from including extreme temperature to the front-right tire, which, on this case, is the outer tire.
Certainly, the front-right compound was already 4°C above the goal temperature, whereas the front-left was virtually at its splendid worth. Demanding an excessive amount of from the Italian F1 automotive in Flip 7 would have overheated the tire and, as a consequence, created a temperature delta resulting in asynchrony. This could have compromised tire administration. Comparable measures have been taken in Flip 10 for a similar purpose.
By lap 41, the ultimate reference level, the front-left tire was progressively warming, whereas the rear finish was now 7–9°C above the goal temperature. Sainz gave his most, and with this Ferrari, he may do no extra. Though issues undoubtedly improved throughout the third a part of the race, the entrance finish ultimately cooled once more, leading to a degree of grip inadequate to get rid of understeer totally.
Total, the Scuderia did not handle its tires as successfully as Mercedes. Within the third stint, Lewis Hamilton’s tempo was superior, permitting him to cross the end line 4.5 seconds forward of Sainz’s automotive. Ferrari was missing a couple of tenth per lap even throughout the race. The Brackley automobiles excelled at shortly discovering and stabilizing temperatures and demonstrated an unmatched capacity to delay the onset of tire graining in comparison with all different groups.
