A crucial F1 Pirelli tyre test ahead of the new 2026 power unit regulations is taking place in Barcelona.
Aston Martin successfully completed a two-day Pirelli tyre test in Barcelona, with the second day taking place today. The test, held at the Circuit de Barcelona-Catalunya, involved a prototype of Pirelli’s new smaller tyres for 2026. These new tyres are part of the changes for the upcoming 2026 season, which will also include new power unit regulations. The front tyres will be 25mm narrower and 10-15mm lower, while the rear tyres will be 30mm narrower, but the same height as the front wheels. Aston Martin tested the tyres on a modified version of its 2022 car to gather accurate data for the new regulations. The test and reserve driver, Felipe Drugovich, completed 670 kilometers of running on Tuesday, exceeding two full race distances. Additional testing will continue today to further evaluate the new tyre specifications.
