An automotive air deflector is substantially V-shaped with a pair of opposed wing panels configured such that impinging air is directed around the deflector. The deflector is configured for placement at various locations on a vehicle, including on the front end of the vehicle, on the rear end of the vehicle, and in front of the tires of the vehicle. The air deflector is constructed of a lightweight material that is sufficiently rigid for the service environment but is flexible enough to be configured in varying shapes so as to accommodate being placed on various types of vehicles and in the various locations on those vehicles. By reducing turbulence and providing for the smooth flow of air around the vehicle, the air deflector reduces the effect of aerodynamic drag, and thus improves the fuel efficiency of the vehicle, thereby leading to reduced vehicle operating costs.

1. An air deflector to reduce aerodynamic drag on an automotive vehicle, the automotive vehicle having a front bumper, a rear bumper and a plurality of wheel wells, said deflector comprising: a plurality of substantially V-shaped deflecting elements, each including a pair of opposed planar wing panels, each of the planar wing panels having an inner surface and an outer surface,said deflecting elements being rigid, bendable and shape retentive and dimensioned to fit entirely within an outer edge and an inner edge of the wheel wells of the automotive vehicle in a front wheel well portion and directing impinging air laterally around at least one of said outer surfaces so as to avoid impacting the wheel wells of said vehicle,wherein the deflecting elements also fits on one of a front outer face of the front bumper and a rear outer face of the rear bumper. 2. The air deflector according to claim 1, wherein an interior angle between said opposed wing panels is from approximately 80° to approximately 100°. 3. The air deflector according to claim 2, wherein said interior angle between said opposed wing panels is approximately 90°. 4. The air deflector according to claim 1, wherein said deflecting elements are positioned for use in front of rear tires in wheel wells of said vehicle. 5. The air deflector according to claim 1, wherein said deflecting elements are positioned for use in front of a front tire in the wheel well of said vehicle. 6. The air deflector according to claim 4, wherein said deflecting elements are positioned in a substantially vertical orientation so as to deflect air around each side of said tires. 7. The air deflector according to claim 2, further comprising a wing extension on each of said wing panels, said wing extension extending from a rear edge of said wing panel and being oriented substantially parallel to a bisector of said interior angle. 8. The air deflector according to claim 2, further comprising a wing extension on each of said wing panels, said wing extension extending from a rear edge of said wing panel and being oriented substantially perpendicular to a plane of said wing panel. 9. The air deflector according to claim 1, further comprising a substantially flat portion disposed between each of said wing panels so as to provide a deflector mounting surface adapted for attaching said deflectors to wheel wells of said vehicle. 10. The air deflector according to claim 1, wherein said deflecting elements are positioned in a substantially horizontal orientation so as to deflect said impinging air both over and under said front bumper. 11. The air deflector according to claim 1, said deflecting elements further comprising a pair of opposed end panels that enclose ends of said deflecting element between said wing panels. 12. The air deflector according to claim 1, wherein said deflecting elements are positioned in a substantially horizontal orientation on a bottommost portion of the rear outer face of said rear bumper so as to deflect said impinging air over said rear bumper. 13. The air deflector according to claim 1, wherein said deflecting elements have a material of construction that is metal. 14. The air deflector according to claim 1, wherein said deflecting elements have a material of construction that is thermoplastic. 15. An air deflector to reduce aerodynamic drag on an automotive vehicle, said deflector comprising: a plurality of substantially V-shaped deflecting elements, each including a pair of opposed wing panels each having an inner surface and an outer surface,said deflecting elements being dimensioned to fit entirely within and in a substantially vertical orientation within an inner edge and an outer edge of wheel wells of said vehicle and secured in said wheel wells in front of tires of said vehicle such that impinging air is directed laterally around at least one of said surfaces so as to avoid impacting said tires, thereby reducing said aerodynamic drag. 16. The air deflector according to claim 15, wherein an interior angle between said opposed wing panels is from approximately 80° to approximately 100°. 17. A system of air deflectors to reduce aerodynamic drag on an automotive vehicle, said system comprising: a plurality of substantially V-shaped deflecting elements including a pair of opposed wing panels each having an inner surface and an outer surface, said deflecting elements directing impinging air laterally around at least one of said surfaces so as to avoid impacting an aerodynamic obstruction associated with said vehicle,said deflecting elements being positioned entirely within an inner edge and an outer edge of a tire wheel well of said vehicle, secured in a front wheel well portion, wherein the deflecting elements also fit on a front outer face of a front bumper of said vehicle, and a rear outer face of a rear bumper of said vehicle. 18. The system of air deflectors according to claim 17, wherein said deflecting element associated with said tire is positioned in a substantially vertical orientation so as to deflect air around each side of said tire, and wherein said deflecting elements associated with said front bumper and said rear bumper are positioned in a substantially horizontal orientation so as to deflect said impinging air over and under said front bumper and over said rear bumper.
