A facelifted version of the Porsche Cayman was introduced on 21 February 2009.
The standard Cayman engine's displacement was increased from 2.7 L to 2.9 L, giving a 15 kW (20 hp) increase to 198 kW (266 hp), while the Cayman S gained direct injection and a 19 kW (25 hp) increase to 239 kW (321 hp).
The new engines no longer had the Intermediate Shaft, which proved to be a weak link in pre-2009 engines.
Both the Cayman and Cayman S maintained a 7 kW (9 hp) power advantage over their roadster sibling, the Boxster.
The design for the front bumper was also kept distinct for the two models.
The front signal lamps are designed differently: while both use LED signal lamps, the Cayman's are arranged like the face of dice while the Boxster has a horizontal row of 4 LEDs.
The Porsche Tiptronic S automatic gearbox was replaced by the 7-speed PDK dual clutch transmission for the new model.
The PDK outperforms the manual transmission with a 0-97 km/h time of 5.1 seconds versus 5.2 seconds for the manual.
The PDK with the sport button option lowers the 0-97 km/h time to 4.9 seconds.

Also a limited slip differential is now a factory option.
