A8
I'll call it "REV-MATCHING".

You can call it what ever you want since you still not sure how the A8's 60ft affects the 1/4 mile speeds or times. There will be no explaining to you what rev match is.
Rev matching is a feature on the M7 you can switch on or off with your paddle! The A8 has no such feature the paddles changes gears up or down when the car is in "M". It is automatic transmission.

So let me direct you to a "Dick & Jane" book!

But seriously anyone with a right leg at anytime can step on gas pedal with A8 and record a good time.
Just need to be at the right track.
Watch Nicd turn his 1.4 60ft on the way to 9.87 @ 142 at a slower track as well! He might be 9.5's at your track
Last post on the fast list! Looks so easy! So easy anyone can do it!

You need to go back to your pot farm and smoke some more weed. You're not making sense again. Not sure if it will help, but it sure can't make it worse.

They have done faster than that! I don't have interest in your books with the covers chewed off.

What are your stock wheel/tire 60' times? Please post your time slips, as I know you will.

He'll have the same excuses; bad da, bad track prep, motor too warm, headwind, bad burnout, quick Christmas tree, previous racer dragged water up to the starting line, not enough rpms, bad gas, too much gas, etc., etc., etc.

The ZR1 M7 will not beat the Z06 A8 either on the 60 ft or the 1/4 mile. But will toast the A8 on the roll. Just like my M7 car now will do to either of you.
HAHA! Again when the 2nd heartbeat will be on my Automatic then it why waste my gas! Have nice day you two jealous birds!

You will need someone who knows his way down the 1320 with a manual and not someone who 'thinks' they know.
On a personal note from the years I spent in the bracket wars rowing a stick I don't think it would be any problem beating the GM stated Z06 A8 1/4 mile time in a manual ZR1.
EDIT: Where's the slips?

Rev matching has to do with using the throttle or ignition or fuel supply to put the engine at the proper rpm for the next gear engaged, reducing shock to the drivetrain and tire contact patch. The A8 does this by blipping the throttle on downshifts, and cutting power on upshifts as needed, similar to what a DCT does automatically. Your denials will not change this.
As far as I have been able to tell, the M7 will only automatically rev match on downshifts, but not on upshifts, although it may reduce power somewhat while upshifting in "no lift shift" mode. But maybe you don't know about "no lift shift" mode either?

How can there be so many different opinions regarding this. Sorry for all you guys that don’t know your cars yet but the throttle blips to match the revs like I’ve asked about. Downshifts into any lower gear when decelerating causes this to happen and becomes more pronounced from 4th down. I can feel it, I can hear it, I actually need to control with braking going into 2nd. I’ve had 35 vehicles, most of the performance models and all but 4 were automatics, none of the others have done this (including paddle shifted ones). My 2018 Zo6 does it, guess I got lucky. Love driving it in manual mode, the A8 was a decision that I labored over because I like the control of an M7. Have driven it for several months now and if you rode with me with your eyes closed, you’d without a doubt think it was an M7 and that I was the smoothest driver ever.
Thanks for your replies !

[QUOTE=Warp Factor;1596317821]They sure do, as explained in post #9, so perhaps you shouldn't be pontificating without ever having even tried it, or reading the owner's manual.
Sure, reading and comprehending the owners manual is harder than reading "Dick and Jane", or other first grade level stuff.
Now that is funny. Yes since 2008, the corvette auto trannies do rev match, as opposed to the 2006/2007 A6 trannies like the one in my 2006 C6 coupe. That tranny was fine for Caddy style cruising, but if you pulled the paddles to downshift, the car would "Lurch" abruptly into gear upsetting any stability you might have especially going around a corner. It was a real H- - - - on.
The 2008 did have rev matching which wasn't a bad first effort and has been improved through out the A6 run and continues to get even better with the A8 introduction.

Look on the GM website order guide or many other places. To learn what GM refer's to as the REV match Feature.
GM Rev match is switchable on of off feature of the Manual M7 Corvette. The computer raises when needed the RPM's to match on down shifts. Using the now dead paddle shifter switch from the A8.
Easier for GM to equip both cars with the paddles. But they do different things depending on if it is A8 or M7.
The M6 did not have this feature. Nor does the A8!
The A8 is simply an automatic with a manual paddle shift-able feature with the shifter in M. The A8 is fully computer controlled
it may raise the RPMs going in gear when down shifting. Not switchable on or off and is not the REV Matching GM refers to on the manual.
That is being confused by a few hopelessly confused A8 owners!

I don't think you have any seat time in an M7! So your making a very uneducated guess! My slips are posted on the fast list.
The M7 ZR1 will have all kinds of problems. With beating the A8. It is not a good 1/4 car. Look at the difference on the list between them.
I own both cars and know more than you about the M7 and have a lot of seat time.
You have none!

Even before that, rev matching was a technique which was necessary to downshift a non-synchronized transmission, in combination with "double-clutching". So rev matching has been around for more like 100+ years, and was around well before GM even existed.
Yes, the paddles on the M8 serve a different function than the paddles on the M7, but that is not what defines rev matching. Not even close. Both have rev matching, switchable on the M7, always active on the A8.
GM may not consider the computer-controlled rev matching on the A8 worth hyping, because many automatic transmissions (and all DCT's) have that these days. It is much less common on a stick-shifted manual, so that makes it worth pointing out to owners and potential buyers.
This is not an indication that the A8 doesn't have rev matching!
