DRS Formula Abbreviation

Drag Reduction System

Also known as adjustable rear wings, DRS (Drag Reduction System) rear wings allow the driver to adjust the wing between two pre-determined settings from the cockpit. The system's availability is electronically governed - it can be used at any time in practice and qualifying (unless a driver is on wet-weather tyres), but during the race can only be activated when a driver is less than one second behind another car at pre-determined points on the track. The system is then deactivated once the driver brakes. In combination with KERS, it is designed to boost overtaking. Also like KERS, it isn't compulsory.
