Abstract: Disclosed are active variable-width aerodynamic spoiler assemblies, methods for making or for operating such active spoiler assemblies, and vehicles equipped with such active spoiler assemblies. A disclosed active spoiler assembly for modifying the aerodynamic performance of a motor vehicle includes a main body rigidly mounted to the vehicle body, extending transversely across the vehicle. The main body has an elongated construction with opposing longitudinal ends. First and second fins are each movably attached to a respective one of the opposing longitudinal ends of the main body. Also, first and second fin actuators are each attached to the vehicle body and attached to a respective one of the movable fins. The first fin actuator is selectively actuatable to independently move the first fin between respective retracted and extended positions, whereas the second fin actuator is selectively actuatable to independently move the second fin between respective retracted and extended positions.
