Audi AWD dimensions

Anyone done a CAD model of an Audi AWD power train and suspension? I know this question is leaving a lot wide open but that is what I want. I am a CAD designer and was hoping someone had done some of this modeling so I don't have to start from scratch. Right now I am thinking 5 or 6 speed manual trans and turbocharged V6 or V8 power. Somebody must have done this. Any and all leads would be appreciated.
