Adding any substantial cargo behind a car would really upset the balance and handling. However, an aerodynamic trailer forming a long, tapered tail can halve the cd. The fairing to the car could be done using overlapping panels to get basic adjustability and flexibility. The car would probably need to have a transition piece to start the fairing, as well as the trailer hitch.
