DRS

DRS (Drag Reduction System) is a movable flap on a race car's rear wing that can be opened to reduce aerodynamic drag and increase top speed on straights.

When activated by the driver pressing a button on the steering wheel, the DRS flap opens, allowing air to pass through the rear wing more easily. This reduces air resistance and can increase speed by 4-12 km/h, making overtaking easier. In Formula 1, drivers can only use DRS in designated zones and must be within one second of the car ahead at specific detection points.

Introduced to Formula 1 in 2011 to improve overtaking opportunities, DRS helps counter the "dirty air" effect that makes following cars closely difficult. While controversial for potentially making passing too easy, it remains a key strategic element in modern motorsport.
