Optimised brake system
Featuring four-piston fixed callipers and a tandem brake servo as well as an extra-large master cylinder, the brake system is tailored specifically to Porsche’s new four-wheel-drive Cabriolets. And to supplement this superiority, Porsche Stability Management (PSM) comes with two new functions: Pre-filling of the brake system serving to build up brake forces even more spontaneously and hydraulic brake force support acting like a Brake Assistant and helping in an emergency to build up full brake pressure even faster than usual. PCCB Porsche Ceramic Composite Brakes are available as an option.
Standard: active suspension in the Carrera 4S Cabriolet
In their concept, the chassis and suspension reflect the new principle of the Porsche 911: The open-air Carrera 4 comes with a conventional suspension, the Carrera 4S features PASM Porsche Active Suspension Management as a standard highlight fitted straight at the factory. This active damping system with two pre-selectable programs is of course also available as an option on the "basic" model.
Sports Chrono Package Plus for the sports driver
Porsche has the developed the optional Sports Chrono Package Plus for the really sporting and ambitious driver, allowing him - or her - to switch various control maps and strategies to a particularly sporting style of motoring. The visible sign which proudly bears testimony to the Sports Chrono Package is the analogue/digital stopwatch on the instrument panel. Driving or lap times stopped by the driver with this special instrument can be saved and evaluated by PCM Porsche Communication Management.
MP3 player and the optional electronic trip recorder
Further enhancement of Porsche’s PCM system ensures even more entertainment and less bureaucracy: The CD player incorporated in Porsche Communication Management as a standard feature is now also able to play MP3 music titles. And as an option we offer an electronic trip recorder with an infra-red interface for reading out the data saved.
The New 911 Carrera 4 / Carrera 4S Cabriolet Open Air in the Four-Wheel-Drive 911
Two new, open-air four-wheel-drive 911s combine two truly outstanding driving experiences in that typical Porsche style: The particular dynamics of four-wheel drive and the refreshing thrill of an open sports car. The two models are the Porsche 911 Carrera 4 Cabriolet featuring a 239 kW (325 bhp) 3.6-litre power unit and the even more powerful Porsche 911 Carrera 4S Cabriolet boasting a 261 kW (355 bhp) 3.8-litre six-cylinder.
In conjunction with four-wheel drive, both models convey this superior power to provide the same kind of superiority on the road whenever required: The Carrera 4 accelerates to 100 km/h in 5.3 seconds and has a top speed of 280 km/h or 174 mph. Given this kind of performance, the car is remarkably conservative on the consumption of fuel, averaging an outstanding 11.3 litres in the composite EU cycle (equal to 25.0 mpg Imp). The S-model is equally impressive also in this respect, consuming just 11.8 litres in the composite EU cycle (equal to 23.9 mpg Imp). And with the power provided by the 3.8-litre engine, the 911 Carrera 4S Cabriolet accelerates to 100 km/h in 4.9 seconds and reaches a top speed of 288 km/h or 179 mph.
