Haven't we learned from Honda that hp numbers by themselves aren't relevant in real life driving situations? Audi's gains appear to be via turbos, which have their own set of problems. And, Porsche's gains are only incremental, and don't offset the inherent case and oiling weaknesses with the "new" 996 case. Don't forget the 996 Twin Turbo uses the GT3 (a la 993 Twin Turbo) case, not the 996 case. Yes, no one expects BMW to stand still, but do you really expect them to create a brand new motor in just one year?
