Although it's not due out for its first public showing until this fall's Frankfurt Auto Show, the 2012 Porsche
911 is full of details that are too good to pass up. The details are specifically surrounding the 911 GT3 that's not expected to arrive until after the Carerra it's based on. Sources cite that the power output will be raised to 480-horsepower through a 3.8-liter 9A1 engine. It will also be equipped with a dual-clutch PDK-S transmission.
