911 Carrera 4S Cabriolet


Performance



The latest 911 has a new generation of engines with direct fuel injection (DFI), and significantly more power. 345 hp is generated by the 3.6-liter boxer (horizontally-opposed cylinder) engine and 385 hp by the 3.8-liter power unit.

The results are outstanding performance and increased fuel efficiency and emission values. All made possible thanks to DFI, VarioCam Plus, an improved lightweight construction, reduced friction and a number of detailed technical solutions.

Character



Irresistible appeal. This has always been a driving force in the development of the 911. There is nowhere better to experience it than during an involving Sunday drive in an open-top 911. This is why every 911 is also offered in Cabriolet form.

Technically, these models emulate the performance of their closed-top counterparts. With a 3.6-litre or 3.8-litre power unit and two or four-wheel drive, including Porsche Traction Management.

Offering uncompromising sports performance to 911 standards, no less.

The same applies where safety is concerned. All 911 models are equipped as standard with full-size driver’s and passenger’s airbags and the Porsche Side Impact Protection System. On Cabriolet models, these are complemented by an effective roll-over protection system. A new, optional feature that has been introduced for open-top driving is seat ventilation – for those particularly hot days.

Incidentally, the 911 Cabriolet models are Cabriolets in the traditional sense: they have a fabric hood. This saves on weight in just the right place – for that low centre of gravity typical of a sportscar, and for reduced fuel consumption. Further refinements to provide that irresistible appeal, even in bad weather.

Cabriolet Safety



Despite their modest weight, the torsional rigidity and flexural strength of the 911 Carrera Cabriolets are exemplary. Body flexing is minimal, even on uneven roads. Additional brace members at each of the rear wheel arches provide additional reinforcement of the bodyshell.

Increased protection if the car overturns is provided by an automatically deploying roll-over protection system. Two spring-loaded roll-over bars are located behind the rear seats. The roll-over sensor continuously monitors changes in body tilt, longitudinal and lateral acceleration and contact with the road surface. In an emergency, it deploys the roll-over bars within a fraction of a second. Of course, all of the 911 Carrera Cabriolet models are also equipped with the Porsche Side Impact Protection System (POSIP) as standard.

Whether it’s sporty open-top driving or the frenzy of the race-track, you can relax and enjoy the experience. Just another crucial advantage of passive safety.
