| Abstract: |
For improving the air drag coefficient of a motor vehicle, discharge openings for a first air stream are provided in a cover part of the vehicle underside directly in front of and exclusively within the area of the wheels; the first air stream is conducted through an air guidance device arranged on the body side whereby a device for reducing the flow velocity of the first air stream is provided inside of the air guidance device. The first air stream has a smaller kinetic energy within the area of the discharge opening than the second air stream which flows through the space between the vehicle underside and the road surface.

We claim:
1. A motor vehicle comprising air guidance means for a first air stream arranged on the body, the first air stream reaching the air guidance means by way of inlet opening means and leaving the air guidance means by way of a discharge opening means provided in the vehicle underside, the first air stream being combined with a second air stream that flows through the space between the vehicle underside and the road surface, the discharge opening means being provided on a cover means of the vehicle underside directly ahead of and exclusively within the area of vehicle wheels, means on the inside of the air guidance means for reducing the flow velocity of the first air stream so that the first air stream has a smaller kinetic energy within the area of the discharge opening means that the second air stream flowing between the vehicle underside and the road surface.
