Porsche 911 Targa 4 - Roof Construction

Roof Construction

At Porsche, design has always been about much more than good looks. Design has always had a function too. Only this way do you become a style icon in automobile design – and remain an influence in that field for decades. Or at least you do if you take sports car design seriously.

The 911 Targa has followed this maxim right from the word go. The roof construction, for example, took the 1963 911 Coupé to a whole new aesthetic level and featured a safety concept that made open-top driving a viable possibility.

But even in the 1960s, the crucial question was: what do you do with the roof? And: where do you stow it? Back then, the solution to this problem was very different from today’s. With the new 911 Targa, our solution is a concept which our engineers call ‘a fully automatic roof system with innovative kinematics’. Though its description may sound a little cumbersome, the roof system itself is anything but. Based on a complex and extremely robust engineering solution, the new system allows the roof to be opened and closed fully automatically in a mere 20 seconds when the vehicle is stationary. When opened, the roof is stowed away elegantly and neatly behind the rear seats.

The materials used for the roof are just as pioneering as the roof concept itself. Two flat magnesium elements keep the fabric roof taut, maintaining that unmistakable 911 silhouette. The heated rear window is manufactured from weight-optimised laminated safety glass. Together with the noise-insulating roof liner, it ensures that road noise is kept to a minimum when the roof is closed.

A wind deflector is integrated into the cowl panel frame. When the roof is open, it perceptibly enhances driving comfort by protecting against draughts and reducing wind noise.

The roll-over protection provided by the Targa bar meets the most stringent demands in terms of safety and body rigidity. The design is spot on too. It invokes the classic shape of the original Targa, as do styling details such as the side fins, the aluminium bar trim and the ‘targa’ logo.

The result is an open-top sports car with the feel and comfort of a 911 Coupé. Sculpture perhaps? Yes, certainly. But a moving one in every sense of the word.
