DRS, or Drag Reduction System, is a device used in Formula 1 racing to reduce aerodynamic drag on the cars and increase their top speeds. This allows drivers to gain an advantage in overtaking maneuvers and improve their lap times.

The DRS system consists of a movable wing on the rear of the car, known as the rear wing flap. When the driver is within a certain distance of the car in front of them, they can activate the DRS by pressing a button on their steering wheel. This causes the rear wing flap to open, reducing the amount of aerodynamic drag on the car and increasing its top speed.

The use of DRS is regulated by the FIA, the governing body of Formula 1 racing. Drivers can only use DRS in designated zones on the track, typically on long straightaways. Additionally, the system can only be activated when the driver is within a certain distance of the car in front of them, typically one second or less.

The DRS system has been a controversial topic in Formula 1 racing, with some arguing that it makes overtaking too easy and takes away from the skill of the drivers. However, the FIA has defended the use of DRS, stating that it increases the excitement of the race and gives drivers more opportunities to pass.

Overall, DRS is a key technology in Formula 1 racing that allows drivers to gain an advantage in overtaking maneuvers and improve their lap times. Its use is regulated by the FIA in order to maintain a balance between driver skill and technology.
