ABSTRACT:
An aerodynamic underfloor panel for the front end region of motor vehicles is disclosed. The panel includes an elastically deformable plate attached at its rear end behind the front wheel casings of the vehicle body and moveably guided at its front end by a guide arrangement disposed at a front bumper skirt. An hydraulically actuated adjusting mechanism is provided which includes a stirrup engaging the top side of the plate to bend the plate downwardly toward the roadway at high vehicle speeds to thereby decrease the aerodynamic lift. During the elastic bending of the plate, the front end of the plate is moved longitudinally of the vehicle along its guide support of the front bumper skirt.
