The invention comprises a method and apparatus for increasing fuel efficiency of a vehicle moving through air, comprising the steps of: carrying, by the vehicle, a tail cone in an undeployed state; deploying the tail cone on a back of the vehicle while the vehicle is in motion, the tail cone comprising a flexible material; and pressurizing, with the air, an interior space at least partially enclosed by the tail cone, the tail cone forming an aerodynamic feature extending at least fifteen inches behind the vehicle, where pressurizing transforms the tail cone from a flexible material to a static and compliant aerodynamic feature, which increases miles per gallon of the vehicle by at least ten percent at speeds in excess of fifty miles an hour through a reduction in drag force on the vehicle.
