The 2024 Formulation 1 season delivered its remaining verdicts within the championship’s concluding act, the Abu Dhabi Grand Prix on the 5.281-kilometre Yas Marina Circuit on Yas Island, however there are nonetheless many extremely attention-grabbing insights to be drawn from the automobiles that characterised this championship, beginning with the truth that their performances exceeded expectations.
This theme was highlighted by the qualifying occasions at among the remaining races of the 2024 Formulation 1 marketing campaign, the place, due to sure components, a larger-than-expected leap ahead in lap occasions was noticed, shocking not solely the groups but in addition Pirelli.
Talking throughout the 12 months’s remaining race weekend, the Italian producer defined how the speeds and enhancements achieved by the 2024 automobiles, each in lap occasions and cargo peaks, turned out to be increased than the simulations had predicted.
Yearly, Pirelli receives efficiency and improvement simulations from the groups for the upcoming season to determine a reference for the potential masses on the tires. Along with its inner simulations, the producer makes use of crew information for comparability, together with long-distance simulations and extra detailed stories shared simply weeks earlier than a Grand Prix.
It’s from evaluating the anticipated information in these simulations with the occasions and cargo peaks recorded on observe that notably attention-grabbing insights emerged. “Within the final races, we witnessed a greater-than-expected efficiency improve and noticed very excessive masses, particularly from two or three groups,” defined Simone Berra, Pirelli’s chief engineer, who carefully analyzes this information to grasp the load ranges performing on every tire throughout the Grands Prix.
“From the simulations, we normally have one for the tip of the season and one for mid-year, and nobody anticipated we might see this stage of load. These load ranges are virtually past expectations.”
Even in the Abu Dhabi Grand Prix, the step ahead was evident, with an enchancment of virtually a second in comparison with the pole place time in 2023. This hole turns into much more pronounced when evaluating Lando Norris‘s 2024 pole time to the place McLaren was 12 months earlier, exceeding a full second. Observing the record of enhancements all through the season clearly highlights the developments, notably on sure tracks.
By late November, Pirelli had already acquired simulations for the following season, that are at the moment underneath analysis and evaluation. For the 2025 Formulation 1 automobiles, nonetheless, the Italian producer has already taken steps in latest months with a purpose to deal with additional will increase in load, modifying tire building to raised reply to the anticipated load values from the groups, which can undoubtedly proceed to rise.
For that reason, it’s not anticipated that building will must be modified mid-season because it was in 2023, a really explicit case the place Pirelli nonetheless reacted rapidly. “We don’t need to change the development throughout the season as a result of we consider it’s not proper. We offer a specification, and this could stay the identical for the remainder of the season,” Simone Berra defined.
“For Silverstone final 12 months, the rationale was that the rise in stress on the tire was fairly important, and we proposed this variation to enhance tire integrity. However we don’t count on to come across an analogous scenario subsequent 12 months [in 2025], as the brand new construction has improved resistance to tire stress.”
Within the case of unexpected points and masses even increased than anticipated, one choice could possibly be to reply by rising tire pressures, a facet that might successfully be evaluated on a race-by-race foundation relying on the circumstances. Nevertheless, Pirelli would favor to not improve pressures an excessive amount of, as this might have unwanted effects.
“We might react by adjusting the stress, however we would favor to not elevate it an excessive amount of, and I believe the groups agree. It’s because rising stress can result in overheating and graining. So, we need to preserve stress as little as attainable,” added Simone Berra. It must also be famous that the brand new 2025 compounds have been designed and developed particularly to cut back graining, which in some circumstances this 12 months was barely above expectations.
Looking forward to the 2025 Formulation 1 championship, there is a crucial consideration: the event curve of the groups won’t observe the identical trajectory seen this 12 months. That is partly as a result of the technical cycle is nearing its finish and partly as a result of the 2026 Formulation 1 season will convey a serious technical revolution. Many groups are already working to find out the very best window to shift focus from the 2025 automobiles to the brand new technical laws. For that reason, in contrast to 2024, when groups launched important aerodynamic updates even till the ultimate Grands Prix, improvement in 2025 could possibly be extra restrained.
