Abstract

The present innovation relates to a device for drag reduction for a ground vehicle, which vehicle comprises a bodywork (2) or similar including a first bodywork section (4, 24), which has a longitudinal extension essentially in the direction of travel (6) of the vehicle and which in direct connection to the first bodywork section (4, 24) transitions at a dividing line (8) into a second bodywork section (10) at the, in relation to the direction of travel of the vehicle, rear end (12) of the vehicle, wherein one or several vortex generators (14, 22) are arranged at the second bodywork section (10, 26), immediately after the dividing line (8) and at the connection to the first bodywork section (4, 24), to reduce the drag at rear end (12) of the vehicle.
