Porsche is advancing in its conversion to direct gas injection. Following the Cayennes last year and 911s recently, the Boxster S and Cayman S also get the system late this autumn. The Cayman S goes from 295 horsepower to 320 horsepower, even though engine size remains 3.4 liters. Torque rises from 251 pound-feet to about 275 pound-feet.
All Boxsters and Caymans, not just the S models, also get the option of seven-speed PDK double-clutch transmission, replacing the Tiptronic S. As with the 911s, this trans will mean the two-pedal Cayman will be quicker to 60 and about as economical as the manual. In fact the PDK Cayman S will crack 5 seconds to 60 mph, we hear, and will be available for the first time with a limited-slip diff, bringing its performance even closer to the 911's. The 997-generation 911 Carrera started life four years ago with just 5 horsepower more.
