One of the easiest decisions for the designers of the http://porsche.com” target=”_blank”>2012 Porsche 911 Cabrio was where to launch it: the http://naias.com” target=”_blank”>2012 North American International Auto Show in Detroit. It was a no-brainer for the Germany-based automaker because the United States loves the 911 Cabrio more than any other country, where sales have continue to surge. The all-new seventh generation is scheduled to hit the showrooms in the spring with almost 4 more inches in its wheel base, a lower overall height, and construction composed almost entirely of lightweight aluminum steel composite. Prospective owners have their choice of either a 3.4 liter or 3.8 liter six-cylinder engine that is capable of pumping out 350-horsepower or 400-horsepower, respectively, through a first of its kind seven-speed automatic or manual transmission.
