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.
Claims1
A motor vehicle comprising:
- an outer contour having associated with it flow-influencing devices capable of reducing an air resistance of the motor vehicle;
- wherein the flow-influencing devices comprise ejection and suction devices having ejection and suction openings integrated in the outer contour;
- wherein the flow-influencing devices are periodically activated by drive devices having a control unit in order to introduce time-dependent disturbances under control into a flow around the outside of the motor vehicle.
