I'm taking the other side of the fence with the Cd values, The only thing in the wind is the front end. The middle and rear end are traveling behind a wind block, the amount of drag induced by that end will be next to non existent,it takes advantage of the otherwise wasteful large wake.

My car has a 0.38 Cd so my guesstimate is it has to be more then 1/3 less drag then my beetle, more like 1/2 so the Cd is about 19.
