Thanks to the innovative magnesium construction, the lightweight soft top of the new Porsche 911 Cabriolet is just as smooth as the roof of a coupé.
Porsche has developed an innovative folding roof for the new 911 Carrera Cabriolet that, when closed, has exactly the same arch shape as the roof of the 911 Coupé. The new soft top offers great aerodynamic benefits. With its lightweight folding mechanism, the hood can be opened and closed up to a speed of 50 km / h.
The construction of the folding roof consists of four segments that seamlessly connect to each other in closed form.
The entire construction is made of magnesium. The four magnesium segments are not connected to the hood, so that they stack smoothly upon opening. The package of the hood, frame parts, roof segments and glass rear window take up very little space.
The electrically operated wind deflector ensures extra driving comfort at high speed. The deflector folds up in a few seconds (up to 120 km / h), with the mesh tensioning between the backrest of the front seats and a moving bracket.
The excellent aerodynamics of the 911 Cabriolet are based on the smooth body shapes, the soft top, the enlarged rear spoiler and the cooling system with its adaptive valves in the nose. The angle in which the rear spoiler is positioned is tailored to the specific requirements of a convertible. With the roof closed, the cw value of 0.29 is almost identical to the 911 Coupé.
The open 911 Carrera S has automatic roll protection. In the case of a roll-up, two cassette modules fold out behind the rear seats. A compact, self-supporting frame of welded and very rigid aluminum profiles has been developed for this purpose. The frame also serves as a body reinforcement and thus contributes to improved torsional rigidity.
