Here's a site about the C32 and SLK32 AMG Cars. I may have posted it before but it might be some good reading for new members.

It provides some interesting information about the engine features, supercharger, engine management etc..

What I did find interesting is they claim that the AMG cars come eqquiped with Thin-Walled Ho-Flow Cermaic Catalytic converters.
