Q8 3.0T V6 Throttle Lag Issue — Any D5 Problem Like This?

Yes, true.
I still think it is built into the cars on purpose and not a deficiency of the motors themselves.
Like maybe they discovered that initial tip-in is responsible for much of the emissions, so they coded in a smoother throttle opening to alleviate it, but it messed with the driver's drive-ability perception.
As you point out it should be all somewhat moot on the hybrid setup yet the Q8 has it and that seems to be where the complaints are at the moment.
I am curious to see how the electric turbos factor into this drive-ability when they arrive. I wish they still offered up the HP/Torque curves of the motors since I'd like to see the RS5 2.9T side-by-side with the identically power rated 2020 S6 2.9T+E. Does peak torque come on sooner? They have even removed the @RPM ratings from the website which used to be a big selling point i.e. 405lb-ft@1400RPM...

My car’s engine code contains the letters CZS, not CZSE as shown in your above diagram. A difference without distinction?...or a different 3.0T V6 variant—perhaps country specific?

Difference without distinction. Yes, country specific, but for all intents and purposes it's the V6 D5 'motor' with the P0 mild hybrid implementation. E.g. the one we all know and "mostly" love

Sorry, but thank you just the same. I know it doesn't pertain to this specific forum, but I was only interested in the 2.9T RS5 motor sans electric turbo and the new 2.9T S6 motor with the electric turbo.
Also if you happen to come across a self study guide on the new 4.0T A8, RS6 that would be tremendous.

Same issue on A8
I have the exact same issue on my A8. Had it 4 months now and really noticeable in the situations you describe. Have to leave in sport mode to stand any chance of avoiding it
Has anyone of you who does drive a D5 (3.0 V6) experienced the same powertrain lag or 2-3 second delayed throttle response engagement that seems to be cropping up on the Q8 forum (with some A6 complaints also)? Creates a potentially dangerous situation when merging into traffic or when on an incline (hill). Some are linking it to the mild hybrid system cutting off the engine when vehicle is coasting or on a rolling stop and then when you engage the throttle the engine boosts RPMs with nothing happening and no transmission engagement for a few seconds. See below thread...

I didn’t sense this on my recent D5 test run last week, even with Start/Stop engaged.
