Bone Stock C7 Z Auto will run 10.70s @129 all day long.....That is about 6/ 7 car lengths a head of a Gen 5 in a quarter mile... Except the one person(Sir Nineball) in the world that can shift as quick as a DCT,but destroying the car doing it..
There is your answer...
LOL @ "destroying the car". Powershifting (shifting without lifting throttle) isn't any harder than simply shifting fast. I'm not on the rev limiter, and my clutch in/out is faster than a slow shifting person that rides the clutch too long between shifts. In fact, several GM cars even have a no-lift-shift feature, which just takes care of the soft rev limiter interruption during a shift - the clutches still see the same hit either way. The only thing that would "destroy" a transmission is missed shifts. Grinding the synchros due to someone's clutch foot not keeping up with their hand on the shifter. But, this doesn't happen if you drive properly.
Same track, same day, the automatic Z06 is not 6-7 cars ahead of a Gen 5 Viper, or a manual Z06. That would be equal to 6-7 tenths of a second. They are more like 2-3 tenths ahead, simply based on how easy they 60'. Keep in mind that all the guys in my article above that were driving their Z06's that day - they also thought they would beat the Viper and get revenge for the infamous roll-racing video that happened a couple weeks before. The guy driving the red Z06 in that article even claimed he should beat me easily on the track, he even posted that on Corvetteforum. He never got out of the mid-12s.
