Porsche, like every other automaker under the sun, is under pressure to produce vehicles with improved fuel efficiency that emits less CO2. The current 911 puts out 225 g/km of CO2, but Porsche believes that it can hack another 10 g/km off that figure with the implementation of start-stop technology on its flat-six engines. Not so fast, say Porschephiles. According to the automaker, buyers aren't fond of such a feature on their arse-engined performance machines. Porsche didn't cite the reasons behind consumer's reluctance, but a 10 g/km reduction doesn't seem like much in the overall product scheme of Porsche.
During the launch of the 2009 911, CAR asked Porsche engineers what the CO2 limitations are of the current flat-six, and according to Thomas Wasserback, "it might be possible to produce a Boxster that emits 180 g/km, it would be difficult to engineer a 911 to produce 200." However, Porsche intents to maintain current performance levels, despite a possible reduction in engine output, by lessening equipment levels and making use of more lightweight materials and body shells. Interestingly, Porsche estimates that the new 911s equipped with the seven-speed PDK transmission, which increases fuel economy and decreases emissions, will account for 80-percent of all 2009 911s sold and could spell the end of the stick shift within five years. However, manual transmissions will remain standard on Porsche's 911 Turbo, GT2 and RS models due to the torque limitations of the PDK gearbox, but a stronger version of the 'box is in development, so expect to see dual-clutch technology on all those models in the coming years.

      If environmental BULLCRAP takes the stick shift out of a PORSCHE, I will officially be MAD AS HELL AND NOT GOING TO TAKE IT ANY MORE!!!!

      I am nearly there already.

      I like the idea of the PDK transaxle. I think it will be good, and a very viable alternative, maybe even mainstream.

      But how dare it completely displace a clutch pedal and H-gate transmission.

      Sorry if some of you have "grown tired" of your stick shift... I haven't, my wife hasn't, and I don't see us getting tired of it anytime before we're old and gray.

      I might even consider buying a PDK-equipped car. But it should NEVER completely displace a proper manual transmission.

      There should ALWAYS be sports cars like Porsche is famous for making, that don't have every electronic nanny known to man (you can opt for a non PASM-equipped Porsche.) and a sports car with a manual transmission, no matter how good the PDK might be.

      It isn't about wringing the very last ounce of performance or shift time out of the system. It is about driver feedback and involvement. A lighter, purer, less-electronically overseen sports car is more involving for the driver. The consequences of bad driving are the driver's to bear, not for the computers to mitigate.

      I can't imagine that Porschephiles are more keen about losing the option of a stick shift, than they are about an engine starting and stopping at it's own accord, not by the driver's command.

      Technology is a very good thing, but there are good things BESIDES technology, like actually DRIVING a well engineered sports car, without computer overlords.

      i cant see the problem with start-stop engines, its not like they are
      going to switch off while you are driving round a corner or something.
      its only when your stationary, whats the need for the engine to be on
      then exactly, wether your driving a porsche or a focus

        It's a good idea on paper, but I suspect once the engine starts to cool, the startup emisions are just as bad as what was saved.

      "Porsche intents to maintain current performance levels, despite a possible reduction in engine output, by lessening equipment levels and making use of more lightweight materials and body shells."

      Hallelujah! As an old-school sports car purist, I've been dying to read that sentence ever since automakers began to really pack on the weight in the last 10 years!

      While outwardly that is sad news, considering that most porsche's lives are rather pampered and consist of urban commuting rather than back-road blasting it makes sense.

      However I hope that the "lesser" models (Cayman, Boxster) are allowed to continue with manuals. Porsche should try to keep at least one model line more visceral and mechanical.

        PORSCHE CANNOT STOP BUILDING MANUALS.

        Blasphemy.

      "For all of those who say that a dual clutch is less fun... since when is going 0-60 in 3.5 seconds, regardless of shifting method, "boring?""

      If there's a place on public roads where I can get my jollies going 0-60 in 3.5 seconds, I'd *love* to know where it is.

      The truth is, as roads become more congested and police surveillance expands, traditional manuals will only become more relevant to enthusiasts. You don't need to speed to enjoy yourself then; with three pedals and a stick, you're intimately connected to the car just squirting from one red light to the next.

      Sadly, fewer and fewer of us seem to espouse this point of view.

      What about a hybrid Porsche?

      It's entertaining to go fast, but it's truly rewarding to actually be part of the process. It's the difference between feeling that you're being moved quickly, to feeling that you've moved yourself quickly.
        • 6 Years Ago
        who are you fooling. because you depressed your left foot once or three times, you think you moved yourself quickly?

        ATTENTION: couch potato logic at work here.

        try getting up and running. THAT is moving yourself.
        what you are talking about is ccordinating the actions of 4 appendages instead of three to direct a 2 ton piece of machinery to do thy bidding, requiring a minimum of physical effort from you the driver.

        and dont by any stretch misinterpret my comments, I love a clutch so I can determine the torque amount when I am on the back country roads but to have to engage the clutch myself, meh, its nice but then the other 90% of the time I am in traffic stuck constantly shifting between two gears because the person in front of me is geared differently and sitting in their sweet spot.

        I see your point, but it is just a matter of taste. I personally grown out of having a manual in a car. It just becomes too much of a hassle after a while. Especially if you don't just take it out to the open road. That's why those manual guys hate my sequential manual gearbox. For that connection with a machine I ride my motorcycle. Not to mention manual in bikes are still faster :P

        Relax, it's relative in this context. Driving a manual is relatively more involving and therefore rewarding in some situations, I didn't say it was the be-all end-all reason for being alive. The pleasure from doing your own shift and clutch work isn't superficial as you imply, because the driver is physically connected to integral parts of the car, and is even integral to the car's function himself, more so than in a non-manual (auto shifting manual or fully automatic). Much of the pleasure is derived from the feeling that the driver and the car are working together to achieve something, rather than the car simply responding to input.
