Ferrari Tests Movable Front Wing DRS for 2026 Aero; Pirelli Finalizes Tyre Homologation

Why it matters: Ferrari recently deployed a movable front wing DRS device during a Pirelli tyre test in Budapest, providing crucial data for the upcoming 2026 aerodynamic regulations and Pirelli's new tyre compounds. This marks a significant step in preparing for F1's future. The big picture: Formula 1 is set to introduce radically different aerodynamic rules in 2026, featuring movable front and rear wings designed to optimize cars for both cornering and straight-line speed. This will significantly alter downforce levels and put new demands on tyre performance. Key developments:

• Ferrari's Movable Aero: Ferrari utilized a modified F1 2025 chassis (mule car) fitted with a movable front wing during the Hungaroring test. This prototype device simulates the lower downforce expected from 2026 front wings, offering Pirelli vital insights into how its new tyres will perform under these conditions.
• Pirelli's perspective: Pirelli boss Mario Isola confirmed the value of the data, stating it helps them understand the impact of these new devices compared to standard tests. While current F1 cars generate most downforce from the floor, not wings, the device still provides a good check on the effect.
• Homologation Deadline: Pirelli reached the September 1st homologation date for its 2026 compounds. Despite retaining 18-inch wheels, the tyres feature a lower diameter, different width, and a completely redesigned profile to adapt to the reduced contact patch and evolving car performance.
• Development Process: Pirelli collaborates closely with teams and the FIA, using both physical mule car testing and virtual simulations. Teams' feedback, including requests for stronger rear tyres, has been incorporated. The challenge is designing a tyre that performs effectively throughout the 2026 season, considering that car downforce will increase significantly from initial levels. What's next: Pirelli has limited remaining tests (Monza, Mugello, Mexico) to fine-tune the compounds. They aim to homologate six compounds to offer flexibility, acknowledging that the true performance of 2026 cars will only become fully apparent during pre-season testing next year.
