Oh - when I saw that Lotus pic, the thing that I was (unclearly) reacting to was the plethora of fins/strakes. The outside "fences" (a.k.a. rear wheel boat tailing) definitely make sense, and there's lots of precedence for those on high-efficiency cars & prototypes.
I bet adding those would probably help the U.F.O.'s aero, and if doing so means the underside of the tail then technically becomes a diffuser (if un-befinned), so be it!
