Abstract

A panel member is disclosed for an automotive vehicle. The panel member is disposed on the underside of the vehicle in a spaced relation to the roadway and includes a first constricted portion in front of the front wheel, and a second constricted portion behind the rear wheel. The constricted portions provide first and second constricted spaces between the panel member and the roadway. The panel member also includes boundary element portions which are disposed along the longitudinal sides of the panel member, generally between the front and rear wheels of the vehicle. The boundary element portions cooperate with the panel member to form an air duct. The panel member is formed to provide an essentially smooth surface and to cover parts of the chassis such as axles, control arms, or the like.
