In Formula One, the DRS opens an adjustable flap on the rear wing of the car to reduce drag, thus giving a pursuing car an overtaking advantage of a car in front. The FIA estimate the speed increase to be between 10–12 km/h by the end of the activation zone.[4] When the flap is closed it increases downforce, giving better cornering.
