Pirelli has taken a significant step towards its 2026 strategy by conducting a test of its future-spec tires with Aston Martin, using the team’s 2023 machine. Despite the aerodynamic regulations for 2026 being yet to be finalized, this test in Barcelona marks a critical juncture in Formula 1’s tire development path. The new tires align with the vision for smaller and lighter cars planned for the future.
The planned changes to the tires include a notable reduction in size. Front tires will be cut by 25mm in width, while rear tires will see a 30mm reduction. Additionally, the tire diameter will be slightly decreased from 720mm to a range between 705mm and 710mm. Despite these modifications, the tires will maintain the same 18-inch rim specifications seen in the current F1 setups.
Aston Martin’s involvement in this testing phase was determined through a lottery system, a method chosen due to the high interest from multiple teams wishing to participate. Mike Krack, Team Principal of Aston Martin, noted, “There was a selection process – or a lottery process – because there was a number of teams who wanted to be part of this test program. We were drawn first, so we are the first to do this.”
In a controlled 670 km run at the Circuit de Barcelona-Catalunya, Aston Martin’s reserve driver, Felipe Drugovich, had the opportunity to test the new tires under real-world conditions in a modified 2023 Aston Martin car. This testing is crucial as it serves as an early indicator of how the new tire dimensions and characteristics perform on track.
However, the test was not merely about early trials. Significant regulatory adjustments and considerations had to be made by the FIA to allow testing on mule cars that simulate the 2026 conditions as closely as possible. Ensuring a level playing field for all teams was a top priority, according to Mario Isola, Pirelli’s head of car racing. “Obviously, on one side, they [the FIA] don’t want to give an advantage to anyone,” Isola said. “On the other side, we need to have cars that are as much as possible representative of the 2026 situation. We will choose, together with the teams, a downforce level that is representative.” He further explained the extensive effort in maintaining fairness. “This is the very first test. We are going to test the baseline to understand if the balance is correct. Obviously, we have simulations, and we have indoor testing, and we already released indoor data to all the teams, as usual, and we are going to distribute the report after the test with the teams too.”
Looking ahead, Pirelli’s tire testing program will soon include McLaren and Alpine, as they join the initial rounds of mule car testing. The remaining teams are slated to participate later in the development program.
This development marks an essential step in not only preparing for the 2026 season but also ensuring that all teams have equal access to the crucial data gathered through these tests. The transparent sharing of information ensures that no single team gains an unfair advantage, reinforcing the spirit of competition that lies at the heart of Formula 1.
As Pirelli continues to refine its tire technology and the FIA inches closer to finalizing the 2026 regulations, the outcomes of these tests will influence the strategic decisions and preparations across the grid. With significant reductions in tire size and weight, coupled with the push for advancements in downforce and aerodynamics, the changes projected for 2026 signal a transformative shift for the sport.
In conclusion, Aston Martin’s test run with Felipe Drugovich represents just the beginning of a crucial phase of innovation in Formula 1. As more teams engage in similar testing, the broader implications for the sport will unfold, promising a competitive and exciting future shaped by these foundational development efforts.
