Unfortunately this is one of the problems with 'standard' PDK.

With PDK S 'manuel' means 'manuel'....unless you are being lazy e.g. slowing to much without changing gear.

So either buy a 991 GT3/RS or buy a 'manuel'.

That's no different to normal PDK.

I used to own a 987 Cayman S which I drove in 'Manual' mode 99% of the time. The only thing the car will EVER do without your input is change down to prevent stalling.

I was never sure why people said otherwise?

And even the standard PDK is good in auto if you are really pushing on, but that is more track than road.

'Normal' PDK is different as it is programmed, whether in auto or 'manuel' mode, to select a lower gear for maximum performance e.g. when the throttle is floored with 'sport' mode activated.

In contrast, PDK S will retain the the gear you have selected until maximum revs are reached, in 'manuel' mode, even e.g. when the throttle is floored.

I had a Cayenne GTS on loan last weekend - 440 hp and 8-speed PDK. I just left it in auto and rarely intervened - that suited the nature of the car. In my Cayman GTS however - see what I said above.
Thought Cayenne was a 8 speed shiftable auto not a double clutch pdk. A small differance perhaps but different in driving charictoristic. Pdk in Macan tho as far as I know.

Wrong.

Normal PDK will do that ONLY if you go past the hard stop at 100% and DELIBERATELY engage kickdown mode.

Having got used to using the paddles 100% of the time on an SMG BMW, I always use the paddles on the PDK (paddle shift wheel is a must if you have the wheel with buttons). It's not a big chore and becomes second nature once you get used to it. And you said it yourself - the gearbox doesn't have eyes and doesn't know what your intentio ns are.
Went to the same school, you HAD to use the paddles, that in turn made the process intuitive, so the comments about "not knowing what gear you are in" cease to become an issue, 'cos you just know what you're in.

As someone else said to the OP previously, you have the wrong car (or the right car with the wrong transmission). End of.

Eh?

You are missing the obvious point.

Like I said....when the throttle is floored normal PDK engages a lower gear. PDK S does not.

Thats the major difference. So in this scenario, PDK S is a true 'manuel'. PDK is not.

Simples.

No, my point is that you originally said it's a 'problem' with normal PDK. I can see no way in which it's a problem, and would have to be a deliberate action by the driver.

The argument appears to stem from our interpretation of 'flooring it'

To me, it means very rapidly depressing the pedal to the 100% throttle position. To you it means literally ramming the pedal into the carpet past the point of the kick-down switch stop.

In my case normal PDK is the same is PDK-S, in your case I agree it would behave differently.

You're right. I thought only the lower models in the range were Tiptronics but they're all slushboxes. Apologies; I've been misleading myself as well as others. frown

with the smg, you have no choice...... kinda fun that way.

i actually prefer it to the sport mode on the Gt4. at least left foot braking feels more natural

This is my first automatic so I am still open to enlightenment but I’m guessing my options are; suck it up or attempt to buy a manual (rare as they are)?
You have been misguided by the cognoscenti's drivel about PDK. It's a feckin automatic. Flog it and buy a manual.

Drivel? Which bits?

What's your experience of different types of ODK transmission?

Op, you can learn to get around the majority of what you are experiencing but the compromise will be too high.

Sell it!

Friend works at an OPC. I've driven them all (regular cars, 911s and Caymans, no GT cars). They are just automatics. Granted, very quick shifting automatics, but still automatics. Most of what's stated here about PDK is drivel to me, and I am already sorry I said it...

It seems though, as if the thread-starter seems to experience the same sentiments about PDK as myself?!

Forgive my ignorance, but is the PDK-S stated in several posts just the PDK box in Sport mode, or a different thing altogether?

Interesting read as I'm thinking 981 Boxster S next, and with the lack of nicely spec'd manuals out there a PDK may be the way to go as so many more of them on the used market. Even then, the 'right' ones are still few and far between.

As has been said, the PDK-S in the GT3 will happily bounce off the limiter if you don't upshift, and will also not kick down.

For a weekend car, absolutely a manual car is the enthusiast's choice. Thing is, the 911 is meant to be the all-rounder. I'd shoot myself if i had to use a clutch in London every day, and sadly that's my journey 90% of the time. So whether it is a 911, Ranger Rover or Smart car, my choice for a daily driver will always be an auto.

I'm struggling to see how people find the PDK 'difficult' to use though. I didn't need any instruction or any handbook to work out how to get the most out of it.

I hate automatics in a sports car and hence why I won't buy one..

They are crap... always in the wrong gear if in auto and can't naturally know which gear I'm in in "manual"

Therefore I buy a proper manual...

Yes I have thanks and no really didn't like it...


Just to add we have PDK in the Macan and it is my first auto I can vaguely get on with in a car... but for a sports car no thanks.

Just in the interests of clarity, (as I was confused by conflicting information when researching before I got mine) normal PDK will also bounce off the limiter all day long. And will only kick down if you choose to go past the 100% throttle stop and operate the switch.

So in real terms there's not really much difference between them other than PDK-S not having the option to kick down if you wanted it to.
