Abstract

An active aerodynamic feature for an underside of a vehicle includes a static panel and a dynamic panel. The static panel has a leading edge attached to a front fascia of the vehicle, and a trailing edge distal from the front fascia. The dynamic panel is movably attached to the trailing edge of the static panel. An actuator is configured to locate the dynamic panel in at least two fixed positions relative to the static panel. The fixed positions include a stowed position, which is substantially aligned with the trailing edge of the static panel, and a deployed position, which is at an offset angle relative to the trailing edge of the static panel and also to the stowed position.
