Meaning and Definition
The aerodynamic phenomenon where a vehicle (especially a racing car or aircraft) experiences increased downforce and reduced drag when moving close to the ground.
In automotive racing, a method of generating significant downforce by channeling air under the car with side skirts and a rear diffuser to create a low-pressure area, thereby 'sucking' the car to the track.
