Abstract

A motor vehicle has an outer contour around which the headwind flows when driving has associated with it flow-influencing structure to reduce the air resistance of the motor vehicle is known. The flow-influencing structure are movably mounted in a vicinity of the outer contour and can be activated periodically with the aid of drive devices in order to introduce suitably time-dependent disturbances into the flow of the headwind in the vicinity of the flow-influencing structure.
