Venturi tunnel
벤츄리 터널
The floor of the chassis features air channels on either side, shaped like inverted airplane wings. As air flows rapidly through these channels, the pressure decreases, creating a strong suction effect that pulls the car towards the ground, known as the "ground effect." This is a key element of the major regulatory changes in 2022.

Frequently asked questions
Where are the Venturi tunnels on an F1 car?
They are channels formed beneath the floor. Their changing cross-section is designed to accelerate the airflow and lower the pressure underneath the car.
How are Venturi tunnels related to ground effect?
The tunnels accelerate the airflow under the floor and create a low-pressure region. The resulting pressure difference is a key part of the ground effect that pulls the car toward the track.
