In a world where single letter monikers demarcate unique editions, Porsche reserves “R” for its special, very special cars. Coming this February, the 2012 Porsche Cayman R ($66,000-$91,000) will arrive to driving enthusiasts’ delight with 10 more horsepower (330 total) and 120 less pounds. Porsche acheives the weight reduction through aluminum door skins, lighter 19″ alloy wheels, fixed spoiler, carbon fiber seats and tossing out trivialities like air conditioning and sound systems giving the Cayman R a svelte 2,855 lb dry weight. Combine this with the 3.4 liter flat-six mid-engine’s extra power, virtually flawless PDK dual-clutch transmission, limited-slip differential, Sport Chrono package and you have yourself a 4.4 second 0-60 mph Porsche Cayman. As for the color, it’s safe to say that only Porsche could pull off the equivalent of lime green and still make it look so damn good.
