Abstract: A vehicle component includes first and second surfaces, in a first travel direction of the vehicle. The first surface is exposed to an air flow having a local main flow direction. In a region of a recess on the vehicle, the first surface forms a flow separation edge where the air flow is deflected from the first surface. The recess is delimited by a leading first wall facing the local main flow direction and a trailing second wall. The flow separation edge extends transversely to the local main flow direction over a majority of a transverse dimension of the recess. In the local main flow direction, the second surface borders on the flow separation edge and forms a part of the first wall. The second surface is disposed so that it is inclined like a chamfer about an acute angle of inclination relative to the local main flow direction.
