I think those two graphs are based on different papers, so maybe the researchers used different vehicles? Anyway, I'd like to know what Hucho has to say about it, and I'd be honored if Phil dropped a comment.
One thing makes me wonder: my car is a square-backed station wagon, but it now has a Kamm-style roof extension, so can it still be regarded as "bluff"? In such a case, would a rear diffuser help more than if I didn't have the Kammy?
