ATLANTA - Featuring 121 pounds less weight and the most horsepower available in a mid-engine Porsche, the 330-hp Cayman R has been created for one reason: pure driving dynamics. With its highly-tuned sports suspension and vigilant attention to weight savings, the third Cayman model offers an even more precise driving experience than the standard Cayman S. A direct descendant of the famous 1950s 550 and 1960s 904 mid-engined, high-performance Coupes, the 2012 Porsche Cayman R is celebrating its world premiere at the Los Angeles Auto Show November 17, 2010.
