The device of this invention comprises an air induction passage for directing air upwardly rearwardly and a planar anti-lift member. The device is mounted at the front bumper, near a headlamp, or at rear bumper, or air dam skirts or at the rear of the radiator grille without substantial alterations of the vehicle's general contour lines. An anti-lift thrust is generated by lowering the point at which the front airstream splits up into an upper stream which moves over the upper surface of the vehicle and a lower stream which moves below the bottom of the vehicle, whereby the vehicle's power of adherence to the ground at the front wheels is increased. The vehicle's adherence power at the rear wheels is also increased by directing the airstream flowing below the vehicle bottom surface upwardly rearwardly of the vehicle. The impact absorbing capability of the vehicle is increased by forming the air induction passage with a resilient material to make the air passage act as an impact absorbing member.

1. A device for improving the aerodynamic and safety characteristics of an automotive vehicle, comprising an impact absorbing member defining an air induction passage extending longitudinally of the vehicle for directing air upwardly and rearwardly of the vehicle from a point forward thereof and through a passage outlet during vehicle movement, and an anti-lift member formed of a material being mounted in said air induction passage, said anti-lift member having a trailing edge positioned higher than a leading edge thereof, said impact absorbing member and anti-lift member being located below the level of a vehicle hood. 2. A device as claimed in claim 1, wherein said air induction passage is formed by a space between an upwardly rearwardly tilted surface of a main front bumper mounted at the front of the vehicle and an anti-lift producing surface of an anti-lift bumper located upwardly and forwardly of said main front bumper, said anti-lift bumper being mounted at the front end of said vehicle by removing part of the vehicle front portion and the front fender panel of the vehicle, and wherein said anti-lift member comprises said anti-lift bumper and an anti-lift plate mounted adjacent the rear edge of said air induction passage. 3. A device for improving the aerodynamic and safety characteristics of an automotive vehicle, comprising an impact absorbing member defining an air induction passage extending longitudinally of the vehicle for directing air upwardly and rearwardly of the vehicle from a point forward thereof during vehicle movement, and an anti-lift member formed of a material being mounted in said air induction passage, said anti-lift member having a trailing edge positioned higher than a leading edge thereof, wherein said air induction passage is formed along an upper surface of an upwardly and rearwardly tilted light transmissive member mounted to cover a headlamp of said vehicle, and wherein said anti-lift member is pivotally mounted adjacent to an opening at the rear edge of said tilted light transmissive member. 4. A device for improving the aerodynamic and safety characteristics of an automotive vehicle, comprising an impact absorbing member defining an air induction passage extending longitudinally of the vehicle for directing air upwardly and rearwardly of the vehicle from a point forward thereof during vehicle movement, and an anti-lift member formed of a material being mounted in said air induction passage, said anti-lift member having a trailing edge positioned higher than a leading edge thereof, wherein said air induction passage is formed by a space between a main rear bumper mounted at the rear of the vehicle and an anti-lift bumper mounted below said main rear bumper, wherein said anti-lift bumper is formed of a resilient material and having a front edge located forwardly and downwardly of said main rear bumper below the vehicle bottom surface, said anti-lift bumper being located by removing part of a panel of a rear fender of the vehicle. 5. A device for improving the aerodynamic and safety characteristics of an automotive vehicle, comprising an impact absorbing member defining an air induction passage extending longitudinally of the vehicle for directing air upwardly and rearwardly of the vehicle from a point forward thereof during vehicle movement, and an anti-lift member formed of a material being mounted in said air induction passage, said anti-lift member having a trailing edge positioned higher than a leading edge thereof, wherein said air induction passage is formed by an upwardly and rearwardly tilted member mounted below an opening in front of a vehicle radiator, wherein said anti-lift member is mounted between side walls rearward of a radiator grille to extend to align the surface of the tilted member so that the front edge of the anti-lift member projects forwardly and downwardly, said front edge of the anti-lift member being formed of a resilient material. 6. A device for improving the aerodynamic and safety characteristics of an automotive vehicle, comprising an impact absorbing member defining an air induction passage extending longitudinally of the vehicle for directing air upwardly and rearwardly of the vehicle from a point forward thereof during vehicle movement, and an anti-lift member formed of a material being mounted in said air induction passage, said anti-lift member having a trailing edge positioned higher than a leading edge thereof, wherein said air induction passage is secured to air dam skirts at a front end portion of the vehicle pivotally to the vehicle frame adjacent vehicle front wheels, said air dam skirts being movable into a downward tilted position by an airstream directed rearwardly from the vehicle front to the vehicle radiator enabling the air dam skirts to be exposed to an airstream passing below the vehicle bottom surface, wherein said anti-lift member is mounted at the front of the inlet opening of said air induction passage.
