• a support member configured to be mounted to the motor vehicle;
• a spoiler panel disposed in a recessed segment of said support member, wherein said recessed segment is exterior to an outer body portion of the motor vehicle;
• a pair of power-operated drive units interconnecting opposite ends of said spoiler panel to said support member and operable to move said spoiler panel from a stowed position within said recessed segment of said support member to a deployed position extending from said recessed segment of said support member, each of said power-operated drive units including a housing configured to be secured to said support member and defining an elongated guide slot, a stanchion secured to a corresponding end of said spoiler panel, a follower assembly mounted to said stanchion and disposed for movement within said guide slot, said follower assembly having a roller rotatably supported on a shaft segment positioned within and in rolling engagement with said guide slot and a retaining ring secured in a groove formed in a position of said shaft segment extending through the guide slot, and a powered actuator for translating said stanchion relative to said housing for moving said spoiler panel between its stowed and deployed positions;
• and
• a control system for controlling actuation of said powered actuator in response to an operating characteristic of the motor vehicle so as to actively control movement of the spoiler panel.
