An active rocker aerodynamic shield integrated into an automated running board for a motor vehicle. By using the existing automated running board linkages as a mounting location for the panels, the addition of a dedicated motor, linkage/pivot, and vehicle attachment scheme is no longer need for the aero benefit since components can be shared. The use of the moving linkages (Inner link, outer link, & lower mount) as attachment points for a panel(s) that is used to limit the flow of air to the underbody of a vehicle. When the miming board is in its stowed position. The panel is also stowed out of the line of sight and airflow. When the benefit of the aero panel is desired, the running board moves to the deployed position, orienting the aero panel in a position to reduce the amount of airflow under the vehicle.
