Thanks Tadge for the information and all your replies through the year.
Love our Z06 and the A8. The car has been flawless and is the best car to drive I've ever owned.
Merry Christmas and Happy New Year

The more you drive the car the better the performance gets!!!! what more could we ask for!!!! For you guys that are "afraid" to put to much mileage on the car you are missing out

Better yet ... when you have the Selector in Manual Shift Mode ... the car should be always calculating and ready to shift -- in other words the shift algorithm should always be running .. not just run when the Paddle is pressed. And why does the automatic have to be so smart ?? Putting the transmission on Manual Mode should actually DUMB things down to closer replicate the M7 experience.
At least, that is what I got from his explanation.

I thought that was the entire point of having a Manual Mode on the automatic ... so I can tell the babysitter to go home .. I want to be able to upshift and downshift at will just like if it was a manual transmission. I can understand the computer preventing a downshift that would break something .. but other than that stay out of my way.

This is a good explanation by Tadge, but it raises a couple questions:
1. Does the Porsche DCT do the same types of calculations to avoid upsetting the dynamics of the car before shifting, or does it "blindly" downshift (As Tadge said that the Corvette does not do)? If the Porsche DOES do these kinds of calculations, how does it do so faster?
2. Since it is performing a series of calculations and this contributes to shift time, would it not make sense to use a more powerful CPU that would perform the calculations quicker, and remove the computing time from the equation? I'm sure owners would be willing to increase the price of the A8 by $20 in order to accommodate a faster CPU.

A logical follow-on question to Tadge would be: given the expectation of continuous improvement in this area, can we expect firmware upgrades to be forthcoming to address the delay?
I have always said hardware was not the issue - good to hear it confirmed.

Just catching up on Tadge's response to this and would love to know where the firmware upgrades are? While Tadge's response was good, it was also incomplete. This paddle response delay definitely seems to be software logic driven. The unanswered question is "why the manual paddle shift is delayed when the A8 automatic shift (assuming it's running relatively similar logic) doesn't experience the same lag?"
A follow on question to this may be "what are the hardware and software differences in the ZL1's A10 that help it avoid the C7's A8's paddle shift response delay?"
