Pirelli Ready to Restart Crucial F1 Safety Talks After Alonso’s Rare Setback
Highlights
- Pirelli open to resuming safety talks after Alonso’s sprint failure
- Alonso’s Aston Martin rear wing failed to activate Straight Line Mode
- SLM failure increased drag, causing Alonso’s slowest qualifying time
- Proposed ‘meatball’ flag could require pit stops for SLM failures
- Pirelli analyzing real-world data from rare active aerodynamic failures
- Safety discussions on SLM flags may reopen next F1 season
Pirelli says it is open to restarting safety talks with the FIA and teams after Fernando Alonso’s sprint qualifying failure at Zandvoort exposed risks with 2026 active aerodynamics.
Alonso’s Aston Martin rear wing failed to enter Straight Line Mode, leaving the flap closed on straights. Drag spiked, and he set the slowest time among the 22 drivers.
Active aero supports the 2026 power unit concept, which splits output 50:50 between combustion and electrical systems. SLM trims drag on the straights where fixed wings would be too costly.
Pirelli designed tyre constructions and pressures around the load profiles expected with SLM engaged. Alonso’s problem gave rare real-world data on how a persistent failure changes forces and behaviour.
Pirelli is open to revisiting SLM safety procedures with the FIA and teams next season.
The most discussed mitigation is a black-and-orange “meatball” flag for cars showing SLM malfunctions. Drivers would be required to pit for repairs, or retire if the fault cannot be cleared.
Simone Berra stresses failures are uncommon but significant. Several teams saw partial wing activations in Friday practice. Comparing telemetry to simulations refines models, margins, and tyre prescriptions.
A black-and-orange ‘meatball’ flag for SLM failures is under consideration for future seasons.
The risk profile is clearest if the rear wing fails to open at the rear axle, or if both front elements remain closed. Balance shifts and straight-line loads rise, elevating safety and tyre stress concerns.
That review aligns with recent Pirelli decisions on tyre safety taken during the season.
For Aston Martin and Alonso, the glitch undermined sprint preparation and race execution. It also feeds scrutiny of reliability as teams scale active aero. Alonso’s future at Aston Martin remains a live topic, and he recently cautioned the team on development priorities.
Alonso’s rear wing failed to enter Straight Line Mode, producing the slowest qualifying time of the 22 runners.
For now, the topic is closed for 2026. Berra signals talks could resume over winter, targeting a clear procedure that preserves safety without blunting the intent of the new regulations.
