Let me hit you with some numbers: The Cayman and CaymanS are equipped with direct-injection, dry-sump, flat-six engines, displacing 2.7 liters and 3.4 liters, respectively.
From the steering wheel to the electrically adjustable sport seats, the metabolism of a well-optioned CaymanS is so much like that of a 911 it's hard to imagine feeling in any way deprived.
