Surely its going to be a centro that been "associatedized" (sorry have no better word for the analogy) as was the B44 with the BJ4. Obviously with some tweaks so there is cross compatibility with the B44 platform and "look" of associated now.
I cant imagine them totally redesigning a mid motor car based on how amazingly popular and well designed/engineered the C4 is and how ridiculously well it goes in the hands of the worlds best and average racers alike.
Just what i reckon anyway!
