An apparatus for reducing atmospheric drag on a vehicle. The apparatus includes an airfoil having a receiving feature, wherein the airfoil is attachable with a back portion of the vehicle. The apparatus includes at least one extender attachable with the back portion of the vehicle, and a slide arm attached to the at least one extender and mateable with the recess portion of the airfoil. The apparatus is configured such that when the slide arm is disposed in the receiving portion of the airfoil, the airfoil is in an extended position relative to the back of the vehicle. The apparatus is further configured such that applying a force on the airfoil in a direction substantially perpendicular to the back portion of the vehicle buckles the airfoil, thereby lifting the slide arm from the recess and moving the airfoil to a retracted position.

1. An apparatus for reducing atmospheric drag on a vehicle, the apparatus comprising: an airfoil having a receiving feature, and the airfoil being attachable with a back portion of the vehicle;at least one extender attachable with the back portion of the vehicle; anda slide arm attached to the at least one extender and mateable with the receiving feature of the airfoil;wherein, when the slide arm is disposed in the receiving feature of the airfoil, the airfoil is configured to be in an expanded position relative to the back portion of the vehicle. 2. The apparatus of claim 1, wherein the extender comprises: a first arm connected to a second arm; and wherein the first arm is pivotally connected to the slide arm, and wherein the second arm is connected to the airfoil. 3. The apparatus of claim 2, further comprising: a ramp arm; anda stop connected to a surface of the airfoil. 4. The apparatus of claim 3, wherein the receiving feature comprises a recess disposed between the ramp arm and the stop. 5. The apparatus of claim 4, wherein the first arm is configured to pivotally move the slide arm into the receiving feature. 6. The apparatus of claim 5, wherein, when the slide arm is disposed in the recess, the slide arm is configured to abut the stop and the ramp, thereby preventing movement of the slide arm and preventing pivoting of the first arm when a pivoting force is applied to the first arm. 7. The apparatus of claim 5, wherein the airfoil is configured such that applying a force on the airfoil in a direction substantially perpendicular to the back portion of the vehicle buckles the airfoil, thereby lifting the slide arm from the recess. 8. The apparatus of claim 7, wherein the airfoil is configured such that when the slide arm lifts from the recess the airfoil moves to a retracted position. 9. The apparatus of claim 3, wherein the first arm is configured to pivotally move the slide arm along the ramp arm. 10. The apparatus of claim 2, wherein the first arm includes a biasing element biasing the first arm toward a retracted position. 11. The apparatus of claim 2, wherein the second arm is configured to pivotally extend the airfoil in a direction away from the back portion of the vehicle. 12. The apparatus of claim 2, wherein the first arm is configured to pivotally provide the airfoil with an arcuate cross-sectional shape in the expanded position. 13. The apparatus of claim 2, further comprising: a support arm connected to the first arm and the slide arm. 14. The apparatus of claim 1, wherein when the slide arm is disposed in the recess portion of the airfoil, the airfoil has an arcuate cross-sectional shape. 15. The apparatus of claim 1, wherein the at least one extender includes a plurality of extenders, and wherein each of the plurality of extenders is connected to the slide arm. 16. The apparatus of claim 15, further comprising: a stabilizing arm, wherein each of the plurality of extenders is connected to the stabilizing arm. 17. The apparatus of claim 1, further comprising: a securing feature configured to secure the airfoil against the back portion of the vehicle. 18. The apparatus of claim 17, wherein the securing feature comprises a latch mateable with a groove formed in the airfoil. 19. The apparatus of claim 1, wherein the air foil comprises a plurality of segments. 20. The apparatus of claim 19, wherein the plurality of segments are pivotally connected to one other via hinges. 21. The apparatus of claim 1, wherein the at least one extender is attached to the back of the vehicle via a bracket.
