Porsche revealed its new 911 Carrera 4S Cabriolet sports car, all-wheel drive version of of the popular 911 open-top models. The new sports car has more dynamic look with wider rear tires and bodywork that is 1.7 inches (44 mm) wider than the two-wheel drive 911 Carrera and 911 Carrera S Cabriolets.
For most favorable occupant safety, the 911 Carrera 4S Cabriolet is equipped with the Porsche Side Impact Protection (POSIP) system that features separate head and thorax airbags for both driver and front seat passenger. Also standard are two full-size frontal airbags and three-point seat belt latch tensioners and belt force limiters for the front seats. Rollover safety features include two ultra-strong steel tubes in the A-pillars and two supplemental safety bars located behind the rear seats that automatically deploy in the event of a rollover.
Like its all-wheel drive 911 coupe brothers, the Porsche Stability Management (PSM) system on this new Cabriolet model has two new functions to enhance braking. First, if PSM detects that the driver has abruptly taken his or her foot off the accelerator, the system 'pre-fills' the brake calipers to reduce the gap between the pads and the rotors, which helps shorten stopping distances. The second system features a hydraulic pump that works like an emergency brake assist, applying full braking power during a hard stop even if the driver has depressed the brake pedal quickly but without full force.
As with the previous version, the 911 Carrera 4 Cabriolet's all-wheel drive system has a multi-disk viscous coupling that transfers between 5 and 40 percent of the driving force permanently to the front wheels. This feature provides excellent handling in curves, straight-line stability at high speeds, and improved traction on slippery roads.
This car, equipped with four wheel drive, is one of the world's fastest convertibles with a top speed of more than 217 mph - or with its classy appearance it can be the perfect companion for every kind of social event.
