A frontal structure for a motor vehicle 100, comprising a deployable air dam 110 movable from a stowed position to one or more deployed positions, wherein the frontal structure is configured such that when a collision event is detected, predicted or anticipated, said air dam is deployed into a first deployed position in which an edge 112a of the air dam forms the lowest point of the frontal structure and another edge 112b also extends to a point of the frontal structure that is at least as far forward as any other part of the frontal structure of the vehicle in the same vertical plane. A further embodiment of the invention comprises a movable member (314, See figure 3) with flexible a membrane 316, covering the member. Additionally the deployable air dam may have a plurality of operating positions determined by the controller depending on vehicle speed.
