Mercedes F1 W03 - 'double DRS' overview 19 April 2012

This drawing 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 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, 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.
