Ferrari's Charles Leclerc set the pace in first practice for the Hungarian Grand Prix with a 1:19.075, ahead of Max Verstappen by about 0.484 seconds and Lewis Hamilton. The session featured Hungary-specific upgrades, including rear-wing configurations for Ferrari and Mercedes, and McLaren planning a floor revision to improve cornering. Aston Martin rolled out a heavily upgraded AMR26 but suffered a major setback when Lance Stroll spun, appearing to suffer a rear-suspension failure. Leclerc's running ended early when his car broke down near the pit entry in the final minutes. Fernando Alonso was 13th for Aston Martin, while George Russell briefly led early on with soft tires before Leclerc's lap topped the times. The day highlighted the competitive front and notable reliability issues surrounding Aston Martin's new package ahead of a busy development weekend.
