Porsche Cayman R

 About :

The Porsche Cayman is a mid-engined, rear wheel drive 2-seat sports car produced by Porsche AG of Germany. First launched in the 2006 model year, the Cayman is a coupé derived from Porsche's second generation Boxster convertible. Like the Boxster, most Caymans were assembled in Finland for Porsche by Valmet Automotive (the rest are assembled in Zuffenhausen, Stuttgart, Germany). Porsche's Deputy Chairman, Holger P. Haerter stated that their contract with Valmet Automotive will end in 2012, and the Cayman's production will be outsourced to Magna Steyr Fahrzeugtechnik of Graz, Austria. (Panorama, 2008). More recently, as Volkswagen assumed ultimate control of Porsche AG, that agreement fell through, and the production of both Cayman's and Boxsters after 2012 will be in the former Karmann plant in Osnabrück, Germany, now owned by Volkswagen and used for production of the new 2012 Golf Cabriolet.
The second generation of the Porsche Cayman was introduced on 21 February 2009. The standard Cayman engine's displacement was increased from 2.7L to 2.9L, giving a 20 hp (15 kW) increase to 265 hp (198 kW), while the Cayman S gained direct injection and a 25 hp (19 kW) increase to 320 hp (239 kW). Both the Cayman and Cayman S maintain a 10 hp (7 kW) power advantage over their roadster sibling, the Boxster. On the front end, each has its own design for the front bumper. The front signal lamps are designed differently: while both use LED signal lamps, the Cayman’s LED are arranged like the face of dice while the Boxster gets a horizontal row of 4 LEDs. The Porsche Tip tronic 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 0-60 mph time of 5.1 seconds versus 5.2 seconds for the manual. The PDK with the sport button option lowers the 0-60 mph time to 4.9 seconds. Also a limited slip differential is now a factory option.
The Cayman R was introduced in 2011, and is based on a 2009 Cayman S. It features a new body kit, new 19 inch lightweight wheels, lighter aluminium doors, lighter bucket seats, and together with the removal of the radio, storage compartments, air-conditioners and door handles, the Cayman R weighs 54.8 kilograms lighter than a Cayman S. With the help of the new sports suspensions, the Cayman R is 20mm lower than a Cayman S. The engine is a 3.4-litre flat six Direct Fuel Injection DFI boxer engine which produces 330 hp (246 kW). The standard Cayman R can achieve 0-60 mph in 4.7 seconds, and with the optional 7-speed PDK dual clutch transmission and the Sport Chrono package, it can achieve 0-60 mph in 4.4 seconds. The Cayman R with the manual transmission can reach the top speed of 175 mph (282 km/h), and 174 mph (280 km/h) with the PDK.
