Formula 1, Sportrik Media - Pirelli has officially confirmed that Mario Isola will step down from his role overseeing Formula 1 tyre operations, ending a three-decade association with the championship and a ten-year tenure leading the company’s exclusive supply programme in modern F1.
Isola has been one of the most recognisable technical figures in the paddock since Pirelli returned as the sole tyre supplier to Formula 1 in 2011. Over the past decade, he has overseen the development of tyre constructions and compounds through multiple regulatory cycles, including the major aerodynamic overhaul introduced in 2022 and preparations for the all-new 2026 power unit regulations.
From March 1, Dario Marrafuschi will assume the position of head of Pirelli’s motorsport business unit. The transition coincides with the opening week of the 2026 season at the Australian Grand Prix, marking a pivotal moment as F1 enters a new technical era.
In a brief statement, Pirelli expressed gratitude for Isola’s contribution.
“The Company wishes to thank Mario Isola for the dedication and great passion with which he has contributed to the growth of the Motorsport business unit over the years.”
Although stepping away from day-to-day responsibilities, Isola will remain within the company structure until July 1 to ensure a smooth transition before departing to pursue a new professional challenge.
During his leadership, Isola played a central role in managing tyre performance amid rapidly increasing aerodynamic loads and evolving chassis philosophies. He worked closely with leading teams such as Scuderia Ferrari, Mercedes-AMG Petronas, and Red Bull Racing to refine compound selections and structural durability across a wide spectrum of circuit characteristics.
In recent seasons, tyre management has become a decisive competitive factor. Drivers including Max Verstappen, Lewis Hamilton, and Charles Leclerc have frequently highlighted the narrow operating windows of modern compounds, particularly under extreme temperature variations. The strategic complexity surrounding degradation, overheating and energy management has placed Pirelli at the centre of performance debates.
The timing of Isola’s departure is significant. The 2026 regulations will introduce revised power unit architecture with a substantially increased electrical component, altering torque delivery characteristics and longitudinal load distribution. These changes will directly influence tyre stress profiles, particularly under acceleration and braking phases, demanding precise calibration of compound resilience and carcass construction.
Marrafuschi, who joined Pirelli in 2008, brings extensive internal experience and will report directly to Giovanni Tronchetti Provera, executive vice president of sustainability, new mobility & motorsport. Continuity within the leadership structure is expected to provide stability as the company navigates both regulatory transformation and sustainability objectives aligned with F1’s broader environmental targets.
For teams such as McLaren and Aston Martin, tyre consistency remains fundamental as aerodynamic and mechanical packages continue to evolve. With increasingly sophisticated suspension systems and energy recovery deployment strategies, the tyre remains the sole interface between car and circuit, amplifying the importance of supplier reliability and development precision.
Isola’s tenure encompassed not only performance evolution but also crisis management, including safety-related tyre revisions and mid-season construction updates in response to emerging data. Maintaining competitive unpredictability while ensuring structural integrity has been a defining balance of the Pirelli era.
As Formula 1 approaches its next technological chapter, the leadership shift within Pirelli signals both continuity and renewal. The immediate challenge for Marrafuschi will be to safeguard performance parity, support strategic diversity, and adapt tyre philosophy to the demands of the 2026 generation machinery.
With the Australian Grand Prix set to open the new season, the transition marks the close of one of the longest-serving technical partnerships in modern F1 history and the beginning of a new phase for the championship’s sole tyre supplier.
