Difference in interior on B7 RS4!

[skramar]

Hello
Could someone explain the difference in interior of a RS4 B7 model

http://z.about.com/d/cars/1/0/9/e/ag_07rs4_interior.jpg - this look like it has an A4 B6 airvents
http://z.about.com/d/cars/1/0/Z/E/1/ag_08rs4cabrio_int.jpg - different steering wheel
http://www.youtube.com/watch?v=umlV71JegUM&NR=1 - in this video it is without carbon trims

I am very confused, it is a B7 RS4 and how it is possible that there is such a difference in interior!!!
HELP!

The carbrio has the round vents. It's not just the RS4, but the same across the B7 platform. The Avant and the saloon both have the same style interior. The different steering wheel is the multi-function option with all the stereo bits on it, but not the sport button - that goes on the dash instead.

Thanks.

In a video RS is without carbon trims, how is that possible?
