A flow-guiding arrangement for a motor vehicle, the flow-guiding arrangement comprising:
- a wing arrangement, which is arranged in a rear-end region of the motor vehicle and has a wing element, and
- an underflow duct with a duct inlet and a duct outlet,
- wherein the duct inlet is arranged upstream of the wing element and the duct outlet is arranged below the wing arrangement,
- wherein the underflow duct is fluidically assigned a throttle device, which is configured to be actuated by a motor and via which an effective flow cross section of the underflow duct is to be varied, and
- wherein the throttle device has at least one flap, which is configured to be pivoted by the motor between a fully closed position and a fully opened position, wherein in the fully closed position the flap is configured to close off the duct inlet substantially completely whereby the effective cross flow section of the underflow is substantially zero.
