A5/S5 engine-trans pic?

[auditodd at comcast.net]

I was reading this article:
http://www.canadiandriver.com/articles/ly/08s5.htm

It mentions that the engine is behind the front "axle".
Does anyone have one of the old fashioned high resolution Audi images of the new engine/transmission combination that would show how they did that?

I'm also a bit confused.
Is the A5 based on the "B" chassis or the "C" chassis?
