Click above for high-res gallery of the 2009 Porsche 911 Carrera S with PDK

The Porsche PDK system is a revolutionary new dual-clutch transmission that gives does lightning fast shifts without the need to move your left foot. That's not the only cool trick up the new Carerra's sleeve when equipped with PDK. The guys at Garage 419 found out from Porsche engineers that front-wheel drive can be disabled entirely by lifting up the parking brake a single notch. Once you lift up that brake, the four-wheel-drive Carerra 4 becomes a Carrera 2 and power slides and donuts are yours to discover. Follow the jump to view Garage 419's video review of the new 997. News about the front-drive shutoff is available at the two-minute mark, but the entire video is worth watching. You can check out our own first drive of the Porsche Carrera with PDK by clicking here.

      AWD FTW! Just wait until this sweet piece of innovation gets handed over to Audi and Lambo as well. I can't say enough good things about AWD and this should shut up the old guard here on autoblog who are obsessed with power only going to the rear wheels. Maybe Porsche will offer a superfluous clutch for them to stomp on too so they can feel "connected to the car."

      donuts are still possible with AWD. I would be more than happy to demonstrate if you loan me a Carerra 4...

      How about adding a "not so useless" clutch pedal to any of these automanual trannies? We've been living with drive-by-wire gas pedals, why not clutch?

      That way you'll have the best of worlds - maximized performance & "stuck-in-traffic" scenario with fully automatic mode and then for when you want to have some "I'll swap my own gears, thank you" fun you have the pedal. Doesn't seem that hard to implement.

      And if they want to make it look cool then can even have the pedal retract or something when the car's in an automatic mode ;)

        I'd go for an airbrake or something on the far left.

        But there's no way I'm buying a car that I have to push a button on the floor just to activate the button on the steering wheel.

      And let me guess Chris.... you are not one of those novice drivers. Because you can really put the 911 to its limits.... I'm sure...
      These car manufactures have to stop making progress!! Damn Them!!!

      The Volvo S60R has this same "feature." Except it disengaged the rear drive portion of the AWD...
        • 6 Years Ago
        That's because the engine in the S60R is in the front. the Porsche part-time auto-engaging AWD system in the Carrera 4 is just a flipped front-to-back version of the kind of system you see in the TT, S60R/Mazdaspeed6 or such.

        As I mentioned above, all of them disengage the enter clutch when the brakes are activated so that antilock braking (or even the apportioning valve) can work.

      Still a girly automatic transmission for the novice drivers of the world.

      Disengaging the front wheels is a good idea, but it doesn't seem to fit the type of driver who would buy a car with this transmission. You would think he would want additional safety measures that intervene on the total driving experience.....like that transmission does.
        • 6 Years Ago
        There is the novice I was talking about.
        • 6 Years Ago
        Then don't buy it? As far as I know, PDK is still an option for all Porsches, and an expensive one at that. Manual is standard on all Porsches still. When PDK becomes standard on Porsches, and Manual is an expensive option, then we will have a problem.

        Stop complaining about how some of us what to drive. If I like PDK, I will buy it, but you don't have to.

      Porsche + 2wd = Windowmaker :)

      seriously, Porsche needs 4wd on all their models.. it should be mandatory safety feature.
        • 6 Years Ago

        Not really, at least not anymore.

        The newer the 911, the more stable, as they figured out how to make it behave better at the limits. The Carrera 2 and GT3 and GT2 are all amazing cars, with RWD only, and are lighter than C4 and Turbo.

        If you see rain or snow... AWD is the way to go. If the pavement stays dry, RWD will do just fine.

        And as much as I like/love AWD... The boxster and cayman are hardly in need of it, with such inherent balance.

        Cayenne has it, because it is an SUV.

        Panamera may or may not have it... probably not, at least not standard.

      @ paul

      actually porsche took longer developing their PDK system so its not the same as audis stronic infact its largely different. The pdk in manual mode wont swap cogs unlike stronic which will upshift before the rev limiter. so it could theoretically trickle down, but the PDK is miles ahead of the stronic

      It seems kinda odd that this feature would only be implemented in the PDK version. This information alone could push some enthusiasts to at least try out the PDK before they make their decision. The biggest gripe people have with automanual transmissions is they try to think for you and dont do what you want. In full manual mode this doesnt happen. It doesnt make sense that this feature sholdnt be in the manual mode though.

      thats one cool trick. to bad its in that car
      • 6 Years Ago
      that means----we can turn a 911turbo to GT2, at least you don't need pay the highest price for two wheel drive with a turbo engine. then,who will buy GT2 ? only for a little more horsepower
      • 6 Years Ago
      wow, sorry thats one hideous car. pop that Porsche badge off and release that thing by any lesser car brand and it would be hailed as the biggest ugly duckling in existence, cool trick though.
