Shut-Off Gurney

Ferrari SF90 Stradale

The end section of the engine cover features a suspended wing divided in two sections: one fixed, which incorporates the third brake light, and one mobile with a wedge-shaped front area.
The latter has been dubbed the shut-off Gurney, a patented active system located at the rear of the car which regulates the air flow over the upper body, reducing drag at high speeds with low lateral dynamics loads and increasing downforce in corners, under braking and during changes of direction.
