i think this is what your talking about:

M does not UPSHIFT in regular driving... even under extreme driving

UNLESS:

you use "kickdown" mode.. in "kickdown" mode (the click after u push pedal all the way down) the car DOES UPSHIFT at max RPM's to give you the fastest acceleration possible....

BUT:

when you let off the "kickdown" the car stays in the last gear, and you must physically shift the car up to let the rev's die down.

great system, i always forget i was in manual mode when i kickdown and when i let off the rev's are at like 5k and i have to shift the car manually.

Nonsense. One is always free to use M.

it's clear that you should no lug the engine. that is bad. you put excess load on bearings and crank and lubrication gets messed up.

generally speaking, if you apply throttle and don't accelerate, you're lugging the engine, which is bad.

I have yet to notice my car's PDK behaving differently than as described by Porsche.

Getting familiar with the owner's manual and the car is the best place to start getting an understanding of the PDK.

rodsky

what? That doesnt make sense. Your car doesnt upshift - when you hit the paddle button or push the gear lever fwd?

You may want to take it in. Thats wrong.

ADias

I do not care what the programmed D (SC Normal) mode is. If I feel that the RPMs are too low I just move to M mode and down shift myself. Crystal clear for you?

No emotions involved in judging RPMs - just experience.

rodsky

I never drive in auto - non-sport.. It changes to higher gears too quickly. Only use auto sport or manual.

mstams

Same here. Mostly manual. I like to keep the RPM's up higher as well.

Lemme clarify. When I'm at full throttle, in M model, the tranny will not upshift unless at the top of the rev range. It wont upshift if I'm, say, at 4000rpm full throttle.


Also you guys are right. In auto mode the tranny does upshift very early. I just drove it this pm and it upshifts into 6th at approx 33-34mph. At that point the engine speed is approx 1400rpms. Seems kinda low to me.

define m mode- m mode on the shifter will have you hit the rev limiter if you dnt advance the gear- when you engage "m" mode by toggling the steering wheel buttons it behaves differently and will resume auto mode on its own rather than hit the rev limiter

stevepow

You've kicked it down and are holding full throttle, yes? So you are telling the car you want maximum acceleration. Just ease up on the throttle and shift when you are done with maximum.

I don't find the low revs/high gear thing to be a problem in a relaxed driving situation - the engine is not lugging (probably can't due to electronic control) - as there is plenty of power to a) keep the car rolling forward, and b) accelerate normally if needed, or c) the program will shift down automatically if necessary. That's not lugging.

If you actually lugged the engine, and again I doubt it will let you (maybe in Manual - have not tried really), it would be very obvious and disconcerting.

That said I usually prefer the less economical Sport mode and/or manual.

Any of you who have used PDK miss a manual transmission?

As has been previously stated, the lowered RPM range for shifting, may have been, more influenced by the need for better gas mileage, possibly to the detriment of prolonged engine life.
I could not continue to use auto comfortably in my own mind, coming from a 6 speed, when shifting was below 2K RPM!
My .02!
PS No, I do not miss my 6 speed!!!

rodsky

I assume by M Model (sic) - you mean manual mode. In manual, it wont upshift at any revs - unless YOU upshift - period. It will bounce off the rev limiter unless you shift. So at 4000 rpm, 5000rpm - it doesnt matter - shift when you want to shift.

In auto - there is normal mode - which is terrible and tries to maximize gas mileage. It tries to get to high gears very fast. I never use this mode.

In auto - there's sport mode. This is what I use. It keeps it in lower gears for longer. Its more aggressive.

Sport Plus is impractical for the street.

rodsky

Not yet I really like PDK especially in manual mode. Stick it in auto if I'm on the phone or chatting with someone in the car.

But again my objective is to drive this car as much as I can. Like every day.
