Default Does Automatic 8 speed have LOWER top speeds???

I wanted to confirm how much lower the TOP Speeds are in our C7 autos. Usually this is the case....what are we seeing in numbers 0-60....100...150 and top end? I am sure most owners would like this info.

Not sure why the A8 would have any lower top speeds? The gear ratios actually suggest better acceleration and top speeds for the A8 vs the M7. I'm pretty sure that the torque converter lockup would eliminate any inefficiencies at top gear runs.

Would imagine our Vettes are speed restricted based on aero... So top speed would vary slightly by gearing at whichever gear gets you to the max speed. That's why the Z06 - Z07 package has a lower top speed due to the downforce of all the splitters, and rear spoiler height. Would imagine the stock base Vette would be fastest when driven without all the spoilers etc..

I heard the factory setting on Z07 have large affect and should be put at lowest setting for top speed.
