Abstract

A motor vehicle includes a rear region, a covering, a drive system arranged in the rear region, and an air-directing component arranged above the drive system. The air-directing component is configured to direct an air flow along a first side of the air-directing component. The drive system is arranged below the covering. At least one recess is arranged on a second side of the air-directing component, the at least one recess being configured to provide an air flow under the covering in the direction of the drive system.

First claim

The invention claimed is:

1. A motor vehicle, comprising:
a rear region;
a covering;
a drive system arranged in the rear region; and
an air-directing component arranged above the drive system, the air-directing component being configured to direct an air flow along a first side of the air-directing component,
wherein the drive system is arranged below the covering,
wherein at least one recess is arranged on a second side of the air-directing component, the at least one recess being configured to provide an air flow under the covering in the direction of the drive system.

2. The motor vehicle as claimed in claim 1 , wherein an air-guiding structure is arranged within the recess and is configured to guide air flowing into the recess from outside the motor vehicle to the drive system.

3. The motor vehicle as claimed in claim 1 , wherein the air-guiding structure has reinforcing ribs for increasing the mechanical stability of the air-guiding structure.

4. The motor vehicle as claimed in claim 2 , wherein the drive system comprises an internal combustion engine and a charge air cooler, wherein the air-guiding structure is configured to guide the air flowing into the recess to the charge air cooler.

5. The motor vehicle as claimed in claim 1 , wherein the air-directing component is configured to, during operation of the motor vehicle, direct the air flow in such a manner that a the air flow exerts a downwardly directed force on the air-directing component.

6. The motor vehicle as claimed in claim 1 , wherein the air-directing component includes a lower part and an upper part, wherein the lower part includes the at least one recess.

7. The motor vehicle as claimed in claim 1 , wherein the air-directing component has a plurality of recesses, and wherein the air-guiding structure is arranged within each of the recesses.

8. The motor vehicle as claimed in claim 3 , wherein the reinforcing ribs are formed integrally with a basic body, wherein the basic body connects the reinforcing ribs to one another, wherein the reinforcing ribs are arranged on one side of the basic body, and wherein depressions are in each case arranged on the basic body opposite the reinforcing ribs.

9. The motor vehicle as claimed in claim 8 , wherein the reinforcing ribs are spaced apart from one another in a horizontal direction, wherein an extent of the depressions in the horizontal direction corresponds at least approximately to an extent of the respectively opposite reinforcing rib in the horizontal direction.
