The Return of Underfloor Suction
Modern Formula 1 has moved away from over-body wings to Ground Effect aerodynamics. By using two massive Venturi Tunnels running the length of the floor, the car creates a low-pressure vacuum that sucks the chassis to the track.
- Clean Air Advantage: This system produces a narrower wake, allowing chasing cars to stay within 90% of their total downforce even when following at high speed.
The Porpoising Problem
The trade-off for this massive suction is “Porpoising”—a high-frequency bouncing caused by the car losing and regaining downforce as it gets too close to the ground. Engineers must balance the Floor Edge Seal to prevent air from leaking into the tunnels while maintaining a stable ride height.
