The mpg benefit you get from drafting is definitely related to the Cd of your vehicle. The Cd on my car is so low I get almost no benefit from drafting.
The mpg you get while drafting is a quick and dirty way to estimate your car's aeromodding potential since the only thing that changes while drafting is the airspeed (and hence the wind load) experienced by your vehicle. Engine rpm's and rolling loads remain the same.
