key technical components behind groups’ optimum working window


Mario Isola, director of Pirelli Motorsport, clarifies the technical components that enable one workforce to realize the optimum working window for his or her tires in comparison with one other. Feedback from the paddock recommend it will depend on the tires, however overheating is definitely associated to the automobiles.

Inside this “window” lies the distinction between success and failure. In System 1, it has grow to be normal apply to reference the “working window” in discussions. Whether or not it’s a driver or an engineer, the idea is a key variable in figuring out if work is progressing in the best path.

Setups are designed to hit the “window,” automobiles are engineered to facilitate this purpose, and drivers adapt their driving types to function inside this vary.

To raised perceive the science behind this “window,” Motorsport.com requested Mario Isola, director of Pirelli Motorsport, to supply an easy rationalization of the technical ideas that dominate workforce briefings: “You must begin with the tread compound, the a part of the tire that touches the asphalt, the place contact generates grip based mostly on temperature,” Mario Isola defined.

“When a driver goes out on monitor, there may be an preliminary warming part the place grip is decreased resulting from low temperature. Because the tire rotates, it heats up, a course of generally known as the warm-up, till it reaches a temperature at which the compound delivers most grip. If this threshold is exceeded, the tire overheats, and grip is misplaced. So the place do drivers all the time need to be? Clearly, on the peak.”

The flexibility to hit the window—outlined by the minimal and most temperatures the place the tire delivers optimum efficiency—will depend on many components. Typically, individuals (particularly drivers) suppose the tire is the trigger, but it surely’s really an impact. The window isn’t solely decided by tire traits however is the results of how a automobile makes use of the tires.

The dimensions of the window varies with completely different compounds, however there are important variations between automobiles. Suspension design is a key variable, however aerodynamic load performs a vital position, because it determines how a lot the tire is pressed towards the asphalt: “If the contact patch is bigger, grip improves, though it’s not the one issue to think about for efficiency,” Mario Isola emphasised. “Distributing the contact floor extra evenly will increase effectivity and reduces overheating as a result of warmth is dissipated over a bigger space. So it’s truthful to say the workforce defines the window with their automobile.”

When Pirelli grew to become the only real tire provider for System 1, one of many requests from groups was to extend the window’s vary, initially outlined as a 3% discount in grip variability. Nonetheless, that vary rapidly grew to become much less related: “A 3% grip distinction right now equates to about one second per lap,” Mario Isola famous, “an unlimited worth given the present stage of competitors in System 1. We’ve labored extensively to realize sensible circumstances in our indoor checks, and now we are able to simulate various kinds of asphalt, temperatures, and circumstances.”

The most recent era of tires has improved in warm-up instances (a sooner course of now) and stabilizes to make sure a broader optimum working window with a extra gradual entry and exit from the window. “The basic instance is overheating,” Isola defined. “When a driver exceeds the window, they really feel a lack of grip and fear they will’t convey the tires again into the optimum vary. Now overheating is extra gradual in comparison with the previous, permitting drivers to note rising temperatures early and handle the state of affairs. To switch the working curve of the tires, we labored on the chemistry and elements of the compounds, reaching barely wider and flatter working curves.”

Pirelli’s problem is advanced, additional difficult by the necessity to present the perfect compromise for ten groups.
“In a single-supplier state of affairs, that’s how it’s,” Mario Isola admitted. “In championships the place tire suppliers compete, the main focus is on the outfitted workforce. It’s a state of affairs we all know nicely from GT championships. However in right now’s System 1, the workforce should design the automobile based on the tire traits. For that reason, groups are asking us for extra knowledge earlier and earlier. We’re already at a stage the place they’ve requested info for 2026 initiatives!”
