I like the looks of the spoiler on the car, but knowing that it actually helps the Cd is what puts a smile on my face!

Hello. I have pretty much abandoned the "raised trunklid" project that I created this thread for. I might return to it at some point. The fabrication was just too far above my skills. The Merkur spoiler came up in a previous thread playing with "bonneville" type spoiler ideas... I am reading Hucho, and it seems reasonable to attach a small spoiler to the tail of the trunk, like the Prius and a many cars available right now, regardless of whether we have the testing precision to show the benefits empirically.
EDIT: I just found a Merkur-like spoiler design on the Ford Probe III, from a 1981 auto show in Germany. That design seems to have had the lowest Cd (0.22) at the show (Hucho, 229).
