From Porsche press: These developments see the engines fitted to the Cayman and Cayman S coupes offering more horsepower than those in the Boxster roadster. This move emphasises the sports driving orientation of the Cayman and further differentiates the coupe.
An outstanding power-to-weight ratio of 4.2kg/bhp on the Cayman S in particular ensures optimum driving dynamics. For example, the Cayman S with PDK and Launch Control (featured in the optional Sports Chrono Package Plus) accelerates from 0-62mph (0-100 km/h) in 4.9 seconds, setting the benchmark in the range.
The Cayman is available with the Porsche-Doppelkupplungsgetriebe (PDK) carried over directly from motor sport, and replacing the former Tiptronic S torque converter automatic transmission. When equipped with PDK, the Cayman accelerates from 0-62 mph (100km/h) 0.1 seconds faster than with the manual six-speed gearbox.
