Excuse me Bostonmini, but you most not know your Porsche history very well if you think "S" has never meant anything before. It always has meant "Super" and from the very early days meant more power and other high performance attributes. Even as recently as now, the Boxster S, means more power and extra gear in the transmission and bigger brakes. It's true that S hasn't meant more more in the 911 series since 1997 (993 Turbo S), but that's not that long ago
