Within the Bahrain Grand Prix pre-race, Ferrari’s technique with Charles Leclerc and Lewis Hamilton was unclear, particularly relating to the selection of beginning tire. Within the main group, everybody opted for the Tender tire for the primary stint on the 5.412-kilometre Bahrain Worldwide Circuit in Sakhir, whereas the 2 SF-25 automobiles began with Mediums. The choice was primarily based on the concept that, with a full gas load, the Italian automotive would have extra tendency to slip.
The usage of the yellow tire, which has a barely increased working temperature vary, may assist enhance the thermal administration of the rear. The choice was subsequently made contemplating the truth that Bahrain is among the most demanding circuits for tire thermal degradation and that the principle restrict is the overheating of the rear, particularly throughout acceleration phases.
With this technique, Ferrari deliberate to make use of the Pirelli tires with the purple band solely within the remaining section of the Bahrain Grand Prix, when the automotive could be lighter and its conduct extra predictable. However, those that began with the purple tire had higher acceleration from the grid. George Russell and Lando Norris, for instance, with much less rear-sensitive automobiles, warmed their tires extra slowly however in a managed method. Within the first laps, Charles Leclerc struggled with the Medium tire. Numerous oversteer, indicating sophisticated thermal administration of the rear. The Monegasque driver additionally reported brake points, described as “inconsistent,” whereas Lewis Hamilton complained of poor grip, once more on the Medium tires. Numerous directions got here from the Ferrari pit.
These referred to the temperatures, together with recommendation on nook speeds at particular factors on the observe. The Monegasque responded that he would do a “Carry and Coast.” Within the first section of the stint, it was evident that the Tender was extra constant. From the tenth lap onward, nevertheless, even the automobiles with the purple tire began to undergo, with Oscar Piastri reporting rear overheating.
Lewis Hamilton reported that the tires had been enhancing, suggesting delaying the pit cease, as his Ferrari race engineer Riccardo Adami confirmed that that they had switched to “Plan B.” Tire cooling on this section is linked to the discount of tread thickness: because the tire wears, it deforms much less, producing much less warmth.
Let’s additionally check out the pit stops and methods to see who made your best option. The primary to pit had been Lando Norris and Max Verstappen. McLaren mounted the Medium tire to strive an undercut on George Russell, contemplating the 5-second penalty. On a high-degradation circuit like Sakhir, the undercut is extraordinarily efficient. Max Verstappen, however, complained of overheating on the entrance and a basic lack of grip.
The RB21 single-seater proves very delicate to temperatures, and the Austrian F1 staff selected to mount the Arduous tire, which is extra manageable however gives much less grip. Lando Norris, 4 laps later, obtained the brand new Medium compound: in line with the engineers of the Italian staff, it was extra aggressive than a used Tender.
At Ferrari, Charles Leclerc made his first cease on lap 19, with the mechanics mounting a second set of Mediums on his automotive. The Arduous tire was discarded after Max Verstappen’s stories, who had radioed in saying there was no grip in any respect. The identical alternative was made for the British driver of the Italian staff.
With the second set of Mediums, Charles Leclerc confirmed wonderful race tempo, recovering time on the main group. Based mostly on the onboard footage, it’s evident how Charles Leclerc managed to stabilize the rear tire temperature, protecting it about +10 levels celsius over the goal. The SF-25 single-seater confirmed good stability and responsiveness throughout this section. At this level, the Maranello staff’s technique was “uncovered” and wanted to make one other cease to alter tire compounds.
However, that they had solely used the Mediums. McLaren was contemplating a double cease, deeming the single-stop technique too sluggish. Additionally they defined to Lando Norris that Charles Leclerc had handed him solely due to a tire that was 4 laps brisker, and that not one of the drivers forward had any Mediums left. A compound that, ultimately, was the perfect of the Bahrain Grand Prix
The Security Automotive on lap 30 neutralized any potential undercut. All of the groups had been already within the superb pit cease window and thus referred to as their drivers in. McLaren mounted the final set of Mediums, confirming the superb strategic administration of the staff. George Russell switched to used Softs, regardless of having Arduous tires accessible.
Ferrari, however, fitted Arduous tires on each automobiles, ignoring the opportunity of mounting the used Softs. The thought was to goal for extra manageable thermal administration. Nonetheless, when the race restarted, the bounds turned clear: Lewis Hamilton instantly reported points with the entrance tires, talking of a scarcity of rotation. The understeer of the SF-25 turned evident, particularly with the white compound.
In hindsight, Ferrari may need cut up the technique and put Softs on one of many two drivers. There was no radio communication discussing tire desire with Charles Leclerc or Lewis Hamilton, though it’s doable they communicated through the steering wheel to keep away from giving any references to rivals.
In comparison with 2024, the SF-25 automotive took a step again when it comes to race tempo. The Bahrain Grand Prix as soon as once more confirmed this, particularly on the very abrasive observe floor. The primary stint with the Mediums and full gas confirmed an excessive amount of degradation. Issues improved afterward, however pure efficiency continues to be missing.
Charles Leclerc acknowledged it clearly: the automotive is just not but as full because the McLaren, making it tough to discover a aggressive setup on each observe. The SF-25 works nicely with the Medium tire, struggles with the Arduous, and is delicate to each exterior situation. There’s a number of work to do. The subsequent race in Saudi Arabia on the Jeddah circuit may spotlight the Ferrari’s rear-end effectivity. And there, each technical and strategic choice will weigh closely.
