Abstract
An active air dam adapted for use with a vehicle, includes a deflector pivotally translatable relative to the vehicle, so as to be caused to achieve stowed and deployed conditions, wherein the deflector, when in the deployed condition, is configured to occlude air flow beneath the vehicle, and further includes an active material actuator comprising an active material drivenly coupled to the deflector, and configured to cause the deflector to pivot to one of the stowed and deployed conditions as a result of activating the material, and the vehicle is preferably configured to cause the actuator to pivot the deflector when a pre-determined vehicle or external condition is detected.
