An automotive vehicle includes a body having an exterior surface and an aerodynamic member movably coupled to the exterior surface. The aerodynamic member has a first position with respect to the exterior surface and a second position with respect to the exterior surface. The first position presents a distinct aerodynamic profile from the second position. The vehicle additionally includes an actuator coupled to the aerodynamic member and configured to actuate the aerodynamic member between the first position and the second position. The vehicle further includes a damper coupled to the aerodynamic member. The damper is provided with magnetorheological fluid.
