In the first picture you can see the wing, and where it will rise up from.



That is a big ole butt!!!!

Yeah the first pic is obviously a Turbo, but the second pic without the wing I believe to be a C4S since it is void of the wing. I could totally be wrong on that like I said in my prior post. But the lack of a wing leads me to believe the 2nd pic is the upcoming C4S

Also of note, the first pic, you can see the exhaust tips are separated into "quads" (two exits each side), whereas the second pic is "dual" tips (one exit on each side). The plot thickens

^^^ noticed that as well. In any case, I love that car!!
