The EPIC Caravan Drag Reduction System by Raisbeck Engineering modifies two parts of the Cessna Caravan equipped with the cargo pod: 1. It modifies the forward cargo pod fairing to reduce drag and to eliminate the cargo pod de-ice boot. 2. The dual aft stakes smooths the airflow separating from the rear to decrease drag and increase directional stability. | Uretsky Aviation

The Drag Reduction System (DRS) in Formula 1 debuted in the 2011 season as a strategic tool to boost overtaking. Under the rules, a pursuing driver must be within one second of the car ahead at a designated detection point, after which they can activate DRS in predefined straight-line zones — opening a flap in the rear wing to reduce aerodynamic drag. This typically results in a top-speed gain of 6–9 mph (10-15 km/h), allowing for quicker overtakes. While DRS successfully increased passing, it a
