911 Model Initiative continuing with Four New ModelsShowing the dynamic attitude typical of the brand, Porsche is continuing the generation change of the 911 model series. Just a few weeks after the new 911s with classic rear-wheel drive, the all-wheel-drive versions Carrera 4 and Carrera 4S are now entering the market in both Coupé and Cabriolet guise.
A whole range of new technologies surrounding the engine, the transmission and drivetrain ensures an even higher standard of driving pleasure on much lower fuel consumption. Particularly the precision and fast response of the new, electronically controlled all-wheel drive offers an even more intense driving experience, above all in interaction with the likewise new flat-six engines with Direct Fuel Injection and the PDK Porsche Doppelkupplungsgetriebe or double-clutch gearbox available as an option.
The features and characteristics of the new engines speak for themselves: Depending on the model, the new all-wheel-drive Carrera offers up to 8.5 per cent more power, up to 12.9 per cent more fuel economy, and 15.4 percent lower CO2 emissions. Specifically, output of the 3.6-liter power unit is up by 20 to 345 bhp. At the same time a Carrera 4 Coupé with PDK, to take just one example, consumes a mere 10.1 liters of fuel per 100 kilometers. The improvements on the 911 Carrera 4S with its 3.8-liter power unit are equally significant, with maximum output up by 30 to 385 bhp on overall fuel consumption down in the case of Carrera 4S Cabriolet with PDK to 10.7 liters/100 km.
In the new generation of the Carrera 4 and Carrera 4S electronically controlled PTM Porsche Traction Management replaces the former all-wheel drive with its viscous multiple-plate clutch. This superior system developed for the 911 Turbo and modified for the Carrera models combines the driving pleasure so typical of Porsche with an even higher standard of driving stability, traction and agile handling further enhanced by the mechanical rear axle differential fitted as standard.
The new all-wheel-drive sports cars come with sporting manual transmission featuring six gears. As an alternative the new models are available with Porsche's new Doppelkupplungsgetriebe replacing the former Tiptronic S automatic converter transmission and offering an even faster gearshift on less fuel. The Doppelkupplungsgetriebe or double-clutch gearbox comes with seven gears shifting electrohydraulically without the slightest interruption of traction and pulling force.
The new generation of the 911 model series stands out clearly through the discreet but striking modification of the front end and new lights technology. The new Carrera models come in all cases with bi-xenon headlights and new LED daytime driving lights.
The newly designed rear light clusters also feature LED technology and for the first time Porsche offers Dynamic Bending Lights as an option. It almost goes without saying that all Carrera 4 models come as before with their muscular rear end 44 millimeters or 1.73" wider than on the two-wheel-drive versions. And a new reflector trim bar between the LED rear lights gives the typical rear end of the car even more dynamic character.
New PCM Porsche Communication Management with its touch-sensitive screen improves operation of the in some cases optional navigation, information and audio systems to an even higher standard. And a further important point is that PCM is now compatible with Bluetooth, USB and iPod requirements.
