A8 to M7
Is it the Automatic that is making the car faster in the quarter?
Maybe a little to none, you should be able to flat foot shift the stick as fast as any auto with the Z06 M7.
the real factor is the gearing.
The whole advantage is the 10.99 overall low on the A8 vs the 7.83 on the M7.
That's means the A8 gets 11 turns of the drive shaft to one turn one turn of the rear.
Where the M7 gets less than 8 turns. Huge almost 50 percent more TQ
to the ground over the M7. In low gear thus the quicker 60fts which is the biggest thing in the 1/8th and 1/4 mile.
Plus lower gearing means slower turning means better traction and quicker recovery if it spins.
higher gear starts should be much more even or towards the M7 which enjoys less drive train loss..
2 different cars altogether!

Stiil info a lot don't really know. Always someone trying wreak a thread around here nothing to add but rude trashing it up causing arguments?
You treat people in person like this? I don't think so!
Maybe just don't bother posting sure don't need your 2 cents on the subject.
FYI!
A lot of people still don't know why and think it just the auto making it faster it is not! It is the gearing.
Don't like it start your own thread!
Have a nice day!

The rowing is great and the M7 will beat the auto through the curves and highway runs but the A8 is much nicer to drive and chill in and rips the M7 a new one off the start.
The A8 is not the old C6 A6 it is intuitive on the right gear.
The A8 adds a luxury feel for those that see in the car and go OH it still has stick?
Then there are those who say they like the stick.
Both are good choices hard to pick that is for sure. So to me the coolest thing is both or having another different car. The Z06 is hard to beat.

The M7 is a joy to drive. The ARM is fun with it. I wonder if the ME will debut with a DCT or whether they'll keep the same M7/A8 (or A10?) offering.
Would be a shame to see the manual trans go away, but with the take rate for it as low as it is, I wouldn't be shocked if they shelve it. Disappointed, but not shocked.

I like the M7 better because it is harder to drive.

Yup.
Nope. No matter how good one is with the manual, the automatic will still shift faster, and be delivering power to the wheels a higher percentage of the time. The auto has the potential for smoother shifts too, helping to maintain traction. However, a few people are really good at slightly slipping the clutch when shifting the manual, helping to maintain traction.
If you are traction-challenged in first gear, a lower ratio and more torque at the wheels won't really help.

It is the gearing!
The Auto is no faster than banging gears with no lift shift!
The lower gear spins slower but delivers far more TQ and does not slip as easy since it is lower geared it spins SLOWER. It has the gearing so less pressure is on tire to grip!
You will catch on one of these days!
Easy proven by the A8 with the 10.99 low vs the 7.83 of the M7.
Almost 50 percent increase in to the ground TQ
The A8 we know cuts 1.5-1.6 with ease the M7 will not do under 1.8
probably more 2.0 bone stock .

You can also use one of the performance analyzers in each type of car, and compare the time lapses in acceleration upon shifting with each type of transmission.
Sure, I'd like to believe I'm superman with a manual too, but the hard reality is that the auto just plain shifts faster.
The A8 has smoother power delivery off the line than most people can get with a clutch. On wet-clutch bikes, we can slip the clutch as much as we need to (all the way through first gear if we want, and on every shift), and the clutch will still be fine. Can't do that on the Z06.

If my Vette was a daily driver I would probably get the auto, but all 12 of my Vette's have been sticks, so as long as they offer a stick I will keep buying it that way. I have an auto in my hellcat, and the way that fries tires makes it a blast to drive too

On a car which has the rpm limit set way above the power peak rpm (and won't come apart doing it) a theoretical argument could be made that during the time it takes to power-shift a manual, the energy from ever-increasing rpms during the shift will be stored in the rotating mass of the engine and flywheel, and delivered back into the drivetrain when the clutch is re-engaged. But that doesn't apply to our cars.

You still haven't even shifted into the next gear and removed your foot off the clutch pedal.
prove me wrong OP.
