Claim 15:
16. An expandable aerodynamic enhancement apparatus comprising:
a support structure that couples to a tongue of a trailer in a position between a tow vehicle and a body of the trailer, wherein the position between the tow vehicle and the body of the trailer corresponds to a space between a rear portion of the tow vehicle and a front portion of the trailer that is a source of aerodynamic drag;
an extendible housing that couples to the support structure; and
a drive assembly coupled to the extendible housing that, when actuated, moves the extendible housing into one of a plurality of aerodynamic states including an extended state that extends the extendible housing into at least a portion of the space to reduce the aerodynamic drag and a contracted state that retracts the extendible housing to reveal a portion of the trailer obscured by the extendible housing in the extended state.
