Yes its very real on the PDK cars. Just look up " Porsche dead stop hesitation" as a search term and you will find lots of discussion about it. It does not happen if the car is slightly moving already, but press the accelerator to the floor from a dead stop and there will be a second of hesitation before the car starts moving. Its just the nature of the PDK transmission which operates similar to a manual in this scenario where there is also a slight delay as the clutch is being let out and engaging with the motor from a stop. The PDK is not an automatic tranny as most are used to. There is no torque converter so you must think of it as a manual without a clutch pedal. You will also notice this "slip" when moving really slow such as in a parking garage. You press the accelerator to move and might sometimes feel the clutches slipping a bit before fully starting to move the car along.
Agreed
This is not any official Porsche PDK update. This is an aftermarket tune installed on the car using the Cobb access port the same as installing an engine ECU tune
. Any car would bog down if all of a sudden you fully open the throttle plate(s). Most cars have that built into the throttle-by-wire programming. Motorcycles dealt with that with a secondary throttle valve controlled by the ECU, until finally TBW arrived. But I got used to extracting maximum acceleration from my motorcycles without it (takes a fraction of a second to reach WOT) with precise throttle control, and maybe that's what I'm unconsciously doing with my GTS, but zero delay on my car, to the point I haven't used launch-control even once. Takes off plenty quick without it, and I live at 4K' of altitude, so performance is less than at sea level. But I do exclusively drive in sport AND manual mode; maybe that could have something to do with it. Bottom line is it's not universal, since many other PDK owners also don't have any issues, and some manual owners do. Good luck.
This C/D long term review gives you an answer for MT, no sports chrono. 0-60 @ 4.2 secs / 1/4mi @ 12.7 sec.
. You can take off whenever you want, like if on a red light. Plus it'd be obvious to people around you didn't use launch control, which makes it pretty obvious with the engine bouncing against the set rpm limit. Plus it aborts if not released after a second or so. With the parking brake, the car takes off like a perfectly executed start with a manual tranny, around 3K-3.5K rpm (I don't stomp the gas pedal at once though). On my LSD-equipped car, it takes off pretty quickly (not like my ex-GTR, but more than quick enough) even at 4K' of altitude, and the tires don't spin (almost, which makes it the ideal start). I suspect it's probably as quick as using launch control, since that surely spins the tires. I only used it once (and twice on my brother's car), since my car takes off pretty quickly just getting on the gas, but I'm always in manual/sport modes..There are so many variables in a 0 - 60 run that it would be amazing if the times were not variable. For example when I was into drag racing, I'd see a car have 30 more HP at 45 degrees than what we measured at 85 degrees. Moreover, when a computerized launch is not used, there's the skill of the driver.An outstanding driver will launch a car a few tenths faster than just an average driver.
