For 2009 there are quite a few modifications to the powertrain to improve power and efficiency. The 3.6L flat-six receives direct fuel injection which bumps up the power to 345 horsepower. The 3.8L engine in the Carrera 4S gets an extra 30 horsepower to 385. A six-speed manual transmission is standard and the PDK Porsche Doppelkupplungsgetriebe or double-clutch transmission is an option. The former all-wheel-drive has also been replaced with the electronically
controlled PTM Porsche Traction Management system, which is also used in the 911 Turbo.
The new 911 Carrera 4 and Carrera 4S will be available this fall.
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
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
