Within the Bahrain Grand Prix pre-race, Ferrari’s technique with Charles Leclerc and Lewis Hamilton was unclear, particularly concerning the selection of beginning tire. Within the main group, everybody opted for the Delicate tire for the primary stint on the 5.412-kilometre Bahrain Worldwide Circuit in Sakhir, whereas the 2 SF-25 vehicles began with Mediums. The choice was based mostly on the concept, with a full gas load, the Italian automobile would have extra tendency to slip.
Using the yellow tire, which has a barely greater working temperature vary, might assist enhance the thermal administration of the rear. The choice was due to this fact made contemplating the truth that Bahrain is without doubt one of 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 pink band solely within the last part of the Bahrain Grand Prix, when the automobile can be lighter and its habits extra predictable. However, those that began with the pink tire had higher acceleration from the grid. George Russell and Lando Norris, for instance, with much less rear-sensitive vehicles, warmed their tires extra slowly however in a managed method. Within the first laps, Charles Leclerc struggled with the Medium tire. A number of 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 monitor. The Monegasque responded that he would do a “Raise and Coast.” Within the first part of the stint, it was evident that the Delicate was extra constant. From the tenth lap onward, nonetheless, even the vehicles with the pink tire began to undergo, with Oscar Piastri reporting rear overheating.
Lewis Hamilton reported that the tires had been bettering, 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 part 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 techniques 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, then again, complained of overheating on the entrance and a common lack of grip.
The RB21 single-seater proves very delicate to temperatures, and the Austrian F1 workforce selected to mount the Arduous tire, which is extra manageable however supplies much less grip. Lando Norris, 4 laps later, obtained the brand new Medium compound: in response to the engineers of the Italian workforce, it was extra aggressive than a used Delicate.
At Ferrari, Charles Leclerc made his first cease on lap 19, with the mechanics mounting a second set of Mediums on his automobile. 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 workforce.
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, retaining it about +10 levels celsius over the goal. The SF-25 single-seater confirmed good steadiness and responsiveness throughout this part. At this level, the Maranello workforce’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. In addition 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 very best of the Bahrain Grand Prix
The Security Automobile on lap 30 neutralized any potential undercut. All of the groups had been already within the perfect pit cease window and thus referred to as their drivers in. McLaren mounted the final set of Mediums, confirming the wonderful strategic administration of the workforce. George Russell switched to used Softs, regardless of having Arduous tires accessible.
Ferrari, then again, fitted Arduous tires on each vehicles, ignoring the potential of mounting the used Softs. The concept was to goal for extra manageable thermal administration. Nevertheless, when the race restarted, the boundaries turned clear: Lewis Hamilton instantly reported points with the entrance tires, talking of an absence of rotation. The understeer of the SF-25 turned evident, particularly with the white compound.
In hindsight, Ferrari might 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 potential they communicated through the steering wheel to keep away from giving any references to rivals.
In comparison with 2024, the SF-25 automobile took a step again by way of race tempo. The Bahrain Grand Prix as soon as once more confirmed this, particularly on the very abrasive monitor floor. The primary stint with the Mediums and full gas confirmed an excessive amount of degradation. Issues improved afterward, however pure efficiency remains to be missing.
Charles Leclerc acknowledged it clearly: the automobile is just not but as full because the McLaren, making it tough to discover a aggressive setup on each monitor. The SF-25 works effectively with the Medium tire, struggles with the Arduous, and is delicate to each exterior situation. There’s a whole lot of work to do. The following race in Saudi Arabia on the Jeddah circuit might spotlight the Ferrari’s rear-end effectivity. And there, each technical and strategic choice will weigh closely.
