VEHICLE HAVING A ROOF AND AT LEAST ONE VORTEX GENERATOR

摘要

The invention relates to a vehicle having a plurality of vortex generators (8) disposed in the region of the rear edge of the vehicle roof. The air guiding bodies (10) of the vortex generators (8) comprise a curved longitudinal axis, whereby improved vortex creation is achieved in the initial region of the vortex generators (8). The flow adheres more strongly immediately after the rear edge of the roof, so that the flow separation region is reduced in the area of the rear window (6) and the adjacent rear hatch. The drag coefficient is thereby reduced and a reduction in the uplift at the rear axle of the vehicle is achieved.
