How does GM justify a GS A8 can do 0-60 in 3.6 and a A8 Z51 in 3.7 sounds fishy
How does GM justify that a A8 GS can do the 0-60 in 3.6 seconds while a A8 Z51 takes 3.7 to do the 0-60 sprint. Sounds fishy to me and seems like a DRIVERS RACE to me 100%. Even my lowly 2014 A6 Z51 does the 0-60 sprint in 3.8 seconds according to GM . TO ME ALL 3 SEEM LIKE A DRIVERS RACE AND A MARKETING PLOY BY GM! The C7 A8 Z06 well that's a whole different story!
I also agree that car mag 0-60 times have close to zero credibility There are so many variables that can make a difference of up to a full second, and tenths of second differences are ridiculous to draw inferences from.
The Z51 is lighter, and the GS has a bit more grip, so it's a draw. The real advantage of the GS is not straight-line acceleration, but it's ability to stick better on a race track.
The 0-60 MPH time of 3.6 seconds reported by GM is for a GS with the A8 transmission and the Z07 Package that includes the soft compound Pilot Sport Cup 2 tires. Without the Z07 Pilot Sport Cup 2 tires, GM reports a 0-60 MPH of 3.7 seconds for both the GS and the Z51 equipped with the A8 transmission.
On a prepared drag strip, with a proper burnout, neither a Z51 or a GS without the Z07 package is traction limited. Under those circumstances, a GS with the Z07 Package would have no acceleration advantage over a GS without the Z07 Package or a Z51.
As a matter of fact, as an experienced drag racer, I can tell you that a Z51 has the potential to turn faster (lower) ET's in the quarter mile than a GS with or without the Z07 Package due to the Z51's lower drag coefficient because of the Z51's narrower body, smaller spoilers and narrower tires.
Yep, agree in a water box with getting the tires hot, perhaps! But as a drag racer you must admit wider tires provide more traction off the line even at the track. But GM is not testing after a burnout on a sticky rubber launch pad!
Granted the top end speed may be slightly less due to drag but since drag is proportional to speed squared, for most on the 1/4 at Vette speeds it's not a factor!
All I know for sure is my Z51 is definitely traction limited off the line! Suspect the same when I get my planned GS!
Guess, as with most beach racing, we'll have to see with some actual timed results! Although that is what GM provides.
PS: Recall the first time I saw Don Garlits at a track where we raced my buddies Olds, he was running eight '97's and no blower! That was ~57 years ago, bit past your 30 years!! Recently was with a NHRA ProStock pit crew at a national event. Almost tripped as my sneakers stuck to the launch pad area in that pro prepared launch pad at the ZMax Dragway!

Wasn't the car mags but GM official Corvette brochures and GM'S official website.
Nothing against the OP, Dave-he's a great guy. And I don't mean to be rude here, but why are we worrying about a one tenth of a second difference? And why are we AGAIN blaming General Motors for something?
Don't you guys ever get tired of pointing a finger at GM for stuff? It gets old......

Steve you are a great guy too but that's just it how do they know where that .1 tenth of a second comes from and why that exact # difference seems to close to call. Didn't mean to come off complaining about GM as I where my GM apparel proudly ! Merry Christmas all my Corvette Forum Friends!
And there was only a .2 difference between a base and a Z51, could that have been driver error too. I would venture to say that very very few here would be able to tell the difference between the Z51, GS and base model.
Reality - these cars are all FAST. The great majority of owners (including this one) never come even close to exploring the full potential. A few tenths of a second here or there - does it really matter? I suspect many of the owners will never reach optimal performance characteristics of the car due to lack of skill and also the fact they weigh too much - lose 50 pounds and you'll probably gain that 0.1 second back. PLUS - you'll find the seats to be much more comfortable.
