The Cayman is essentially a Boxster coupe. The base model is powered by a 2.7-liter flat-six engine. Offering higher performance, the S and GTS versions pack a stronger 3.4-liter flat six. In our tests of the 2.7-liter Boxster, we found it to be responsive, and the manual shifter is smooth and crisp. The automated manual transmission (called PDK) works well and suits the car. Handling is excellent, and the ride is pretty compliant for a sports coupe. The front trunk and hatchback provide a surprising amount of storage space. A GT4 version is the newest version, with a 385-hp, 3.8-liter six-cylinder engine. Reliability has been below average. The renamed 718 Cayman will get the same 2.0- and 2.5-liter four-cylinder turbo engines from the new 718 Boxster.
