Click above for a high-res gallery of the 2009 Porsche 911 C4 and C4S

Well, you knew this was coming. Porsche has followed up the debut of its freshened 997 rear-wheel-drive range with the introductions of the all-wheel-drive 2009 911 Carrera 4 and Carrera 4S. Visually, the C4 and C4S are immediately distinguishable from their 2WD counterparts via the red reflector strip spanning the width between the taillamps. That's a nice touch that brings back some fond memories of the 911s of our youth. The C4's rear bodywork is also wider than that of the 2WD cars. Up front, you'll find the same schnoz introduced a couple of weeks ago.

As with the Carrera and Carrera S, the C4 range also gets the new, direct-injected engines and the optional seven-speed Porsche Doppelkupplung (PDK) twin-clutch gearbox. Power is up, and so is efficiency, while emissions output goes down. The Carrera 4's 3.6L flat six makes a stout 345 horses, and the step-up Carrera 4S pumps out 385 ponies from its 3.8. It's not just the engine and tranny that are new -- the previous car's all-wheel-drive system has now been replaced by Porsche Traction Management, which trickles down to the C4 from the mighty 911 Turbo. Want to scoff at lousy weather and still drive a 911? Come October (in Europe) your new ride will be waiting.

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
October 2008.

      The taillights look sad.
      • 7 Years Ago
      I like it. It's purdee. But the reflector strip sorta makes the butt look like the Cayman in one of the pics. Not a bad thing mind you. Kudos to Porsche for sticking with the same shape all of this time. But I do think they are going to run out of bumper designs pretty soon.
      • 7 Years Ago
      For the the sake of just changinging!, change the car ,will ya!!!!!!! If you go back twenty years and the car looks pretty much the same. so the corners go smooth out and rounded it out more and more each so called update , but its the same freaking non appealing ride. Traditon can only take the car so far . a totally new look for the porche should had happen years ago .........Bottonline ,2009 porche ...??? who cares!!!!!!
      • 7 Years Ago
      Now I really have a tough time deciding which one to buy. CS4 or Nissan GT-R.
      • 7 Years Ago
      Now those reflector strips don't look out of place.......
        • 7 Years Ago
        I see an option to get rid of them (hopefully).
        • 7 Years Ago
        Looks like they went to ugly lincolns for that reflector thing.
        • 7 Years Ago
        seriously!! what the hell is that? why would they put that on there??
      • 7 Years Ago
      Geez I'd hate to be a designer at Porsche. Apparently all you're allowed to do is changes to the long-in-tooth 911 like adding a reflector strip to the rear of the car. How on earth are the stylists earning their (no doubt) high salaries? Are there lengthy debates on whether a 1.5" strip will make the car look 'really new' compared to a 2.5" strip? I wonder if they lose sleep over big decisions like that?
      • 7 Years Ago
      At least the reflector section doesn't look out of place........ what a poor attempt at giving it "the look" of the 996 c4.
      • 7 Years Ago
      October in Europe? Try June in Washington, crazy weather.

      I like the new look, subtle improvements as always.
      • 7 Years Ago
      the new taillights are unbearable.. looks like something from Japan..
      • 7 Years Ago
      100hp per liter is the minimum expected from Porsche.
      BMW (Old) M3...3.2 liters/333 hp.
      BME (new) M3...4.0 liters/414hp
      Audi S4...4.2 liter/420hp.

      What do not Porsche understand?

      OTOH, perhaps the motor output is, ahem, understated. I've driven a couple of older 3.8 cars that seemed to have more than the rated 350hp....
        • 7 Years Ago
        Since when have the base models ever made 100hp/L?

        And also, the 3.8L now makes 383hp, so in fact it now does indeed hit the 100hp/L mark.

        But really who cares? 80hp/L, 90hp/L, 100hp/L? It's going to be an amazing car either way. You don't hinge the decision to buy a car like this on how much power per liter it makes. You hinge it on how well it handles and how fast it is.
        • 7 Years Ago
        There are only a few atmsperic engines that have more torque per litre then the new 3.6 and 3.8 from Porsche. The 3.8 produces more torque then the 4.0 V8 from the M3.
        And i think Porsche has proven more then once that they can get allot of power from atmposheric engines, just look at the 997 GT3, 415hp from a 3.6.
        • 7 Years Ago
        Your note on the Audi is a little off the 4.2L Audi with 420 hp is the RS4 and R8 only. Audi makes many many more 4.2L engines with 330 to 350hp in the S4, A6, A8, and Q7.

        I agree hp/liter is not a great measure of performance. Now, hp/kg that is something to compare.
        • 7 Years Ago
        If thats what you cars about so much then you should be looking into the S2000 (120hp/liter), not a porsche.
        • 7 Years Ago
        Porsche has VarioCam+, so you can conceivably upgrade the 3.6 from 340hp to 360hp. [The 3.8 already has the 'upgrade']

        and torque / liter is damn good.
        3.800- 310ft-lbs@4400 81.58 ft-lbs / litre (99.9hp / litre)
        3.614- 288ft-lbs@4400 79.69 ft-lbs / litre (and only 94hp / litre)

        Base3 engines-good
        Direct injection & 12.5:1 compression ratio, also good.

        Just get a bike and leave the Porsches for people who appreciate them then.
      • 7 Years Ago
      ok, so not uch new here as expected, but somehow those headlights remiiiiinded me of a Mini when I first saw the pic of the front (white one)
      • 7 Years Ago
