What is claimed is: 1. Motor vehicle having a front end comprising an air guiding device which has a pneumatic operating element in order to operatively displace the air guiding device from an inoperative position into an operative position, wherein the air guiding device has a spoiler lip comprising a flexible and elastic material, wherein the pneumatic operating element is constructed as an inflatable hose arranged, viewed in a driving direction, behind the spoiler lip, and wherein the elastic spoiler lip rests in the inoperative position under prestress against the front end. 2. Motor vehicle according to claim 1, wherein the hose has at least two chambers which are arranged above one another and which, viewed against the driving direction, are arranged offset with respect to one another. 3. Motor vehicle according to claim 1, wherein the hose, viewed in the cross-section, has a drop-shaped, oval, or circular construction. 4. Motor vehicle according to claim 2, wherein at least one of the chambers, viewed in the cross-section, has a drop-shaped, oval, or circular construction. 5. Motor vehicle according to claim 2, wherein, viewed in the cross-section, the chambers have different sizes. 6. Motor vehicle according to claim 4, wherein, viewed in the cross-section, the chambers have different sizes. 7. Motor vehicle according to claim 5, wherein the chamber situated adjacent to the spoiler lip has the smallest cross-section. 8. Motor vehicle according to claim 5, wherein the chamber situated adjacent to the front end has the largest cross-section. 9. Motor vehicle according to claim 2, wherein the chambers have a mutual air connection. 10. Motor vehicle according to claim 3, wherein the chambers have a mutual air connection. 11. Motor vehicle according to claim 5, wherein the chambers have a mutual air connection. 12. Motor vehicle according to claim 2, wherein each of the chambers is separately supplied with air. 13. Motor vehicle according to claim 3, wherein each of the chambers is separately supplied with air. 14. Motor vehicle according to claim 5, wherein each of the chambers is separately supplied with air. 15. Motor vehicle according to claim 2, wherein the chambers are fastened to one another or are held above one another under the front end by at least one material lengthening of the chambers. 16. Motor vehicle according to claim 3, wherein the chambers are fastened to one another or are held above one another under the front end by at least one material lengthening of the chambers. 17. Motor vehicle according to claim 5, wherein the chambers are fastened to one another or are held above one another under the front end by at least one material lengthening of the chambers. 18. Motor vehicle according to claim 1, wherein, viewed in a transverse direction of the vehicle, the spoiler lip has mutually spaced ventilation openings for supplying air to wheel brakes. 19. Motor vehicle according to claim 2, wherein, viewed in a transverse direction of the vehicle, the spoiler lip has mutually spaced ventilation openings for supplying air to wheel brakes. 20. Motor vehicle according to claim 3, wherein, viewed in a transverse direction of the vehicle, the spoiler lip has mutually spaced ventilation openings for supplying air to wheel brakes. 21. Motor vehicle according to claim 18, wherein the ventilation openings are reinforced in edge areas. 22. Motor vehicle according to claim 1, wherein, at a free end, the spoiler lip has a pocket in which a bending-elastic element is arranged which extends approximately along the entire width of the front end and which can be displaced in the pocket in a transverse direction of the vehicle. 23. Motor vehicle according to claim 2, wherein, at a free end, the spoiler lip has a pocket in which a bending-elastic element is arranged which extends approximately along the entire width of the front end and which can be displaced in the pocket in a transverse direction of the vehicle. 24. Motor vehicle according to claim 3, wherein, at a free end, the spoiler lip has a pocket in which a bending-elastic element is arranged which extends approximately along the entire width of the front end and which can be displaced in the pocket in a transverse direction of the vehicle. 25. Motor vehicle according to claim 5, wherein, at a free end, the spoiler lip has a pocket in which a bending-elastic element is arranged which extends approximately along the entire width of the front end and which can be displaced in the pocket in a transverse direction of the vehicle. 26. Motor vehicle according to claim 1, wherein the front end has a recess which extends along the width of the front end and, in which, the hose and the spoiler lip are situated in the inoperative position. 27. Motor vehicle according to claim 2, wherein the front end has a recess which extends along the width of the front end and, in which, the hose and the spoiler lip are situated in the inoperative position. 28. Motor vehicle according to claim 3, wherein the front end has a recess which extends along the width of the front end and, in which, the hose and the spoiler lip are situated in the inoperative position. 29. Motor vehicle according to claim 22, wherein the front end has a recess which extends along the width of the front end and, in which, the hose and the spoiler lip are situated in the inoperative position. 30. Motor vehicle according to claim 1, wherein, viewed in the driving direction, the front end is curved out. 31. Motor vehicle according to claim 1, wherein the air guiding device is arranged on an underside of the front end. 32. Motor vehicle according to claim 1, wherein the air guiding device can be displaced as a function of a driving speed of the motor vehicle into the operative position and back into the inoperative position and vice-versa. 33. Motor vehicle according to claim 1, wherein the spoiler lip and the hose or chambers are manufactured in one piece and form a prefabricated module. 34. Motor vehicle according to claim 2, wherein one of the hose and at least one of the chambers, viewed in a transverse direction of the vehicle, is constructed to be elastically flexible and to be substantially inflexible in cross-section. 35.
