Formula 1 fans may be interested to know about the ‘Double DRS’ system that everybody is discussing this year, so we try to explain it here for you. This drawing above shows Mercedes clever ‘double DRS’ system in its entirety. Air is sucked into holes in the rear wing endplates (left inset) which are exposed when the DRS (Drag Reduction System) is activated. Using similar channelling (highlighted in yellow on car profile) – but in reverse – to that utilised two seasons ago for the now-illegal F-duct, the airflow is routed into the beam wing, across the top of the deformable rear crash structure, forwards along the side of the engine and then through the chassis (centre inset) before it exits through the front-wing pillars to blow onto the front-wing flaps (right inset), stalling the wing, cutting drag and boosting top speed.
