GM did the same thing with its Cd 0.19 Impact/EV1 for a record speed run:

Note the ... - extended boat tail,
- lowered ride height,
- smooth wheel discs,
- rear wheel skirts (stock on the production EV1)
- full grille block (the EV1 ultimately had no grille, but some versions of the Impact prototype had stylistic openings, as well as openings for electronics cooling)
- external mirror delete,
- improved deflectors ahead of the front tires,
- ... and lots and LOTS of speed tape!

Great find. Love the duct tape.
