I'm just curious as to whether or not any of you cats with shiny new Grand Sports have tested GM's claim that it's .2 seconds faster to 60mph than a standard Corvette. I'm no engineer, but that sounds suspiciously like marketing strategy. It has the same LS3 engine and the same transmission. Two-tenths of a second would be a massive improvement from just a suspension package, especially since the GS is carrying all that extra bodywork. Anyone have any substantiated gouge on this???

Should be some interesting responses, although I myself doubt anyone can tell if their car is .2 seconds faster.

jpee

One word will explain it all...........

BADGES!

Or cares I bought mine for the ZO6 look with a vert top

Why would anyone care. Did anyone really buy one because GM says it's .2 seconds faster than a base corvette, or a Z51, or whatever?

Dans C6

i'm sure someone did.

Heavier brakes, fenders and the addition of a dry sump. All this added weight and yet it is .2 seconds faster with all the same equipment for generating power.

I am thinking that it is faster because of the traction since it has bigger rear tires?

When the car was unveiled by the GM engineers they claimed that the car was a tenth or two faster than a base C6. I assume that claim is based primarily on the wider tires allowing for a faster/better launch.

Keep in mind that the claim was made by the engineers before any real track testing was done. It is/was based entirely on the cars specifications and the engineers expertise. Given the same exact driving conditions and driver expertise the GS will probably beat the base C6 by a hair.

We will have to wait until GM finishes their in depth testing, but I think it is safe to say that the difference is probably so small that I would have to believe the the GS is NOT really faster.

LET'S ALL MAKE A PLEDGE TO PUT AN END TO THIS QUESTION NOW AND NOT LET IT SNOWBALL INTO ANYTHING LIKE ALL THE Z51 ARGUMENTS!

It's possible, with the wider tires, dry sump and suspension setup. As to one of us feeling a .2 second difference!

The base coupe is 500lbs lighter and is more aerodynamic.
No scoops, badges or bulging fenders to impede air flowing over the body.

Has GM taken the GS to Germany for tesing on the "ring"? I sure hope so with all the hoopla surrounding it. be interseting to see track times as they compare to other super high performance cars tested there to include other Corvette's.

steve miller

The Base Coupe isn't 500 LBS lighter. I don't feel like looking it up but the GS certainly doesn't weigh 3700LBS. Having said that I can imagine it could be a hair slower then the base with the bigger brakes, scoops, etc. but who cares?

GM hasn't had the extra $$ to track test a Corvette at the ring since the last ZR1 test. IMO you won't see the GS tested there unless done by independant testers such as a mag.......but they don't have the resources to shut down the "ring" and test a lesser vette (performance wise). IMO the only vette that might get run at the ring from now on is the ZR1 unless something radical is added to the C6 lineup....unlikely.

The 'ring would be fun though....

Silver05GTO

This is what i think is unfortunate about the GS, people are by in large buying it for the look only and don't care if it's a hair slower or a tick faster. If GM really wanted to kick C6 sales way up they should just offer the base car AS a widebody period........for people who want more performance, the Z06/ZR1 are always there too.

Which begs the question (reminds me of Bill Clinton), exactly what do you mean by faster?

This is actually one of my pet peaves. If you measure "faster" by acceleration from a dead stop, then traction is a huge factor. But if you measure how fast a car is from a roll - which is what most drivers really care about in real world driving, then 0-X times are pretty meaningless.

Car & Driver has done the best job of addressing this issue for many years by showing both a 0-60 and a 5-60 time. Interesting that the 0-60 is always faster than the 5-60 time despite the fact that you have a running start in the 5-60, huh?

Allow me to clarify. I'm asking the question out of academic interest. I'm not trying to bash anyone's GS. When it comes to racing two-tenths of a second is pretty substantial, especially on a vehicle that has the same engine and transmission and a little more weight. Obviously a person is not going to notice .2s difference. Some people on this forum get pretty serious and I wondered if someone might have made a timed run. Can tires alone account for that much difference? I ask because I don't know. Not trying to start an argument.
