As usual, you miss the point, although most other people can see it. The fact that there are other aspects of a manual gearbox which are not included in PDK does not change that.
I agree with Moose on this. PDK gearboxes are great and offer an alternative/preferred way of driving for some....but a PDK gearbox in manual mode isn't anything like driving a car with a manual gearbox. If you haven't got a manual clutch, it isn't a manual. You can't have 'half a manual' car....

I also agree. All PDK does is allow you to choose what gear to be in, which even old-fashioned autos do (albeit they are crap).

Not sure what you are trying to say? Have you missed out the word 'like' after 'anything', in the sentence above?

If so, the point is that a conventional auto chooses what gear to be in for you, whereas manual mode on PDK-S allows the driver to choose. That's the important aspect of a manual gearbox that is retained.

No one is saying it is!

In 'manual' mode in PDK-S you get to control exactly which gear you are in at any particular time - the difference is that you do it with a paddle on the wheel, not a lever and a clutch etc. this is quite different than a conventional auto gearbox.

No one is disputing that a true manual offers other benefits too.

Yes. I'd edited this before your reply....

I am not sure what you are trying to say. Is 'thr' meant to be 'the'?

Hello, I'm here for the argument......no you're not...



I think what Sidicks is trying to say is that with the PDK-S gearbox, you can select a gear and use it for as long as you like with whatever throttle you like and the gearbox will not change gear.

So, its like a manual gearbox in the fact that you can select a gear (say 2nd) and then stay in that gear for your whole commute if you like using varying throttle inputs from almost tickover to redline and back again and the gearbox will not change automatically.......unless its to stop the car stalling I guess.

I can't say I mind that PDK will change down to avoid extreme labouring or stalling. I do mind the bloody kickdown function - that is infuriating (but a sensible safety feature, perhaps). It would be nice to be able to toggle kickdown on and off - on when driving on the motorway (because I have twice in past 5 years had to boot it to avoid someone sideswiping me as I overtake, and the 1/2 second to flick down two gears is too long) and off the rest of the time.

I assume that PDK-S doesn't have kickdown at all. Is that right?

I find kick down a pain too - but if there was distinct second pressure to invoke it as in autos of old it wouldn't be an issue.

On PDK-S:
Kickdown operates when in 'auto' mode.
Kickdown does not operate when in 'manual' mode.

Thanks. Better than the normal PDK, then, but switchable would be better still (perhaps turned off in sport/sport plus). I want it on the motorway but not when having a fun drive.

I think the safety advantages of a good auto are usually overlooked, especially with a lot of manual cars being miles from the power band at motorway cruising speed. Pootling along at 1500 rpm in 6th and suddenly needing a lot of acceleration to avoid some half-asleep idiot wouldn't be much fun. Wouldn't the following steps take too long to enable you to avoid quite a few standard motorway accidents (fool in middle lane switching to L3 without looking, for example)?

(1) Anticipate collision and decide to accelerate rather than brake.
(2) Remember there is fk all power unless you change down.
(3) Racing change down 2 or 3 gears.
(4) Boot it.

Of course, as an alternative to 2 - 4, you might just stamp on the throttle in the cruising gear. In fact, I expect that is more likely for most people, but it won't do much good if your car is long geared and/or has a high boost threshold.

(As a caveat to all this, I noticed that 6th was sufficiently short in the 981 that I had for a few weeks that it wasn't a million miles from power at 70-80mph. PDK 7th, by contrast, would be bloody useless!)

Interesting. A genuine "semi-auto" or, perhaps, "semi-manual".

And how then is PDK-S that any different from a boggo torque converter running in manual mode without a kickdown feature programmed in....?

There are any number of half way houses Almost all motorcycles have a clutch, but you can change up without using it (and always would on the track) and if you have a seamless box as motogp bikes you don't need it going down, just for starts. The same applies to many race cars - with a dog box (FF F3 etc) you don't use the clutch going up the box and with some sequential boxes use of the clutch is optional going down. And then there were manual (H pattern) boxes with a torque converter - (NSU RO80) some H pattern boxes with an electrically operated clutch when you touch the lever. Not to mention the Ford Model T where you change gear with the "clutch" pedal. And then of course there are a variety of preselector gearboxes...
