maybe they mean Cd?

i can't watch the vid with audio for the moment (no sound @ work and no internet at my appartment yet) so i'm just looking at the images.

there's an interesting bit about the rear spoiler, where the first version is straight and the second seems to have something which reminds me of a gurney flap.

i've seen certain BMW's wich also have a small gurney flap like spoiler added. and quite a number of cars with a slight upward sweep to the rear spoiler lip.

given it's shown in this video i wonder what it's use is and how it works to aid FE. it would be a relative simple and good looking addition to my car, but i'd like to understand better what it's supposed to do.
