DRS in Formula 1 stands for Drag Reduction System. It is a driver-controlled device introduced in 2011 to aid overtaking and improve wheel-to-wheel racing by temporarily reducing the aerodynamic drag on the car. The system works by opening a flap on the rear wing of the car, which decreases downforce and drag, allowing the car to achieve higher speeds on straight sections of the track. DRS can only be activated in specific zones on the circuit, known as DRS zones, usually on straights where top speed is crucial. To use DRS, a driver must be within one second of the car ahead at a designated detection point before the DRS zone. If this condition is met, the driver is allowed to activate DRS, giving them a speed advantage to help with overtaking. The flap closes again before corners to restore downforce needed for handling. DRS is disabled in certain situations, such as during wet conditions, the first two laps of a race, or immediately after a Safety Car period. It can also be deactivated by braking or lifting off the throttle. While DRS has made overtaking easier and races more exciting, it is somewhat controversial, with some critics arguing it reduces the skill required to pass. In 2026, F1 plans to phase out DRS and replace it with a new system involving low-drag modes and power-boost modes for more dynamic and strategic racing.
