Williams chief aerodynamicist Juan Molina details the radical changes defining the 2026 F1 season in an exclusive Autosport video. Moving beyond the ground-effect Venturi tunnels of the past, the championship mandates a shorter, narrower car profile and a return to flat floors. This significant step down in downforce presents teams with complex challenges, particularly the 'inwashing' of tyre wake to promote closer racing.

Molina also examines the strategic shift from traditional DRS to new 'straight mode' active aerodynamics, where front and rear wings now work in tandem to toggle between high-downforce cornering and low-drag straight-line speeds.
