Porsche introduces the drop-top sibling of the new 2012 911 introducing a new roof design that maintains the signature roof line we all know and love. The new roof uses magnesium to keep things light while also providing improved fuel efficiency. Power-wise the cabriolets will share the same flat-six engines as its coupe equivalent, the 3.4 liter 350 hp variant and the 3.8 liter 400 hp engine at the top end. Badass.
