'Splain it to me?

["Al Powell" <APOWELL@agcom.tamu.edu>]

Hey gents, since I'm a used-car type buyer, and the nearest Audi 
dealer is 90+ miles away, I confess to getting lost and out of date 
on the nomenclature for the re-numbered Audi line.

I think the A4 is about equivalent to the 90, and the A6 is the 
equivalent of the 100....correct?

So - what is the designation for the A6 turbo?  Is it called the "A6 
Turbo", or is that just too obvious?

And what's the A8?  The V-8 with 100-type body?

And I'm only guessing at S4, S6, S8, etc.....

Someone please take a minute to run down the model line.  TIA!
