We all the time say that Dash Race weekends can present a great indication of the methods we would see within the Sunday race. This time, nonetheless, fortuitously, that’s not fully true. The climate situations on Saturday, with rain arriving simply minutes earlier than the beginning of the Dash, didn’t permit groups and drivers to check their tempo on slick tyres, which can depart everybody heading to the beginning grid in a state of deep uncertainty. Particularly since rain is anticipated once more tomorrow. Showers are forecast proper within the afternoon.
Pirelli’s recommendation – Miami Worldwide Autodrome – 57 laps
Earlier than entering into the main points, let’s hear from Mario Isola, Pirelli’s Motorsport Director, who shared his ideas after Saturday and the recommendation he gave to the groups: “The Dash was filled with twists, primarily because of the climate. The Intermediate tyres suffered from excessive put on as soon as the racing line dried out, notably on the entrance proper. The change to slicks proved instantly very aggressive, a lot so that everybody moved to dry tyres, even those that had constructed a big benefit.”
“This issue may play a significant position within the race if rain returns: in that case, drivers might want to handle the Intermediates very fastidiously. If it stays dry, the restricted knowledge gathered solely confirms the pre-race predictions by way of technique. Regardless of introducing a tyre compound one step softer than in 2024, a single cease technique is, on paper, the quickest, with Medium and Exhausting tyres taking centre stage. 9 out of ten groups (the one exception being Racing Bulls) saved two units of C3s, not a lot to make use of each within the race, however to have one as a backup in case of security automobiles or pink flags—situations which might be something however unlikely on a observe like this,” Isola concluded.
For drivers and engineers, it will likely be like happening a blind date
Drivers and groups have collected little or no knowledge on any sort of compound. If it rains, groups can depend on about 10 laps of expertise on Intermediates, whereas if it stays dry, solely Mercedes, having accomplished a full mini race simulation in the course of the sole free observe session, has knowledge on the C4 tyre to base its technique on.
Nonetheless, it’s not too dangerous. From what was seen in the course of the Dash, the truth that, when it was time to modify from Intermediates to slicks, groups selected to suit the C4 Mediums for the handful of laps left (round eight), offers a transparent indication of the very low confidence within the Gentle compound’s efficiency. Nonetheless, Lewis Hamilton confirmed promising tempo within the few laps he was capable of run freely, which, not less than in line with the writer, makes the C5 an fascinating tyre for the race in case, as within the Dash, there’s a necessity to modify from Intermediates to slicks.
If as an alternative it doesn’t rain and the observe stays absolutely dry, somebody may attempt to full the GP with a Medium/Exhausting one-stop technique, as George Russell and Kimi Antonelli accomplished a future of 18 laps on the C4 throughout observe. If degradation is extra important, groups may change to M-H-H (most groups have two units of Hards), or M-H-M, and even M-H-S.
The C5, contemplating what Hamilton was capable of do, looks like fairly an fascinating choice. A Security Automotive late within the race will surely favour its use. In variable situations, and with doubtlessly excessive degradation, the undercut may change into a really highly effective device. Overtaking is feasible, particularly if the situations change. For that cause, methods involving two stops appear to be the most suitable choice in the intervening time. The one-stop choice additionally stays very aggressive, so there are a number of viable paths forward, all technically intriguing. After all, the choices engineers should make on the pit wall will closely depend upon the precise climate situations on observe.
