Porsche Carrera 4 with Electronically Controlled All-Wheel Drive
Stuttgart. Showing the dynamic attitude typical of
the brand, Dr. Ing. h.c. F. Porsche AG, Stuttgart, are 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 per cent lower CO2 emissions. Specifically, output of the 3.6-litre power unit is up by 20 to 345 bhp (254 kW). At the same time a Carrera 4 Coupé with PDK, to take just one example, consumes a mere 10.1 litres of fuel per 100 kilometres, equal to 28.0 mpg imp. The improvements on the 911 Carrera 4S with its 3.8-litre power unit are equally significant, with maximum output up by 30 to 385 bhp (283 kW) on overall fuel consumption down in the case of Carrera 4S Cabriolet with PDK to 10.7 litres/100 km, equal to 26.4 mpg imp.
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 millimetres 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.
All all-wheel-drive Carrera models will be at the dealership as of 25 October 2008.
