VW has to be careful how much power they engineer into the Passat for fear of cannibalizing sales of the premium A6/A7. Some folks won't waver from their purchase of the premium Audi badge, but if the Passat is nearly as powerful as the 325-hp A6, and the body style of the CC is sleek enough, VAG may start to lose customers at Audi dealerships. As with many things, this is not a matter of 'if' they could engineer more power, but 'why'.
