Default 2011 corvette brochure

Inside statistics---0 to 60-----Quarter mile

Regular C6----4.2 sec-----12.6 sec. @ 115 mph

Grand Sport----3.95 sec------12.3 sec @ 117 mph

Z06----------3.7 sec------11.7 sec @ 125 mph

ZR1----------3.4 sec------11.3 sec @ 131 mph

Question---Why is the G.S. faster than the Regular model ??

I seen on one of the Corvette sites-- 2011 Shelby Mustang --stock--12.3 sec @ 117 mph !!!

My Vette is modded--runs close to the ZO6---should keep me out of trouble-----2011 late, Camaro will have the 552 hp motor !! Time for GM to up the HP on ALL the Vette's !!!

In reality it might not be as the GS is also a little heavier...but the wider rear tires and better gearing (inside the transmission of the manual model and inside the rear of the automatic model) might have something to do with it.

I'm always a little skeptical about manufacturer claimed performance. I'm not saying they're lying only that individual results may vary in the real world.

I'm confident the GS is not faster. They are heavier with the same power as a base.

They would not sell as well if it said that though

It's not, maybe on paper.

Does the GS have launch control? If it does, that could explain it.

The GS gets the old Z51 gearbox if you have a manual tranny, or the performance axle if you have the A6.

Those items used to be available on the base cars, but not any more. That, with a very little help from the wider rear tires, is what makes the GS "faster."

Similar to Wayne O, I'm not skeptical about manufacturer claimed performance; I simply stopped believing it when nobody could get close to the 3.9 sec 0-60 that GM originally claimed for the 2001 z06.

I have never ran a 12.6 with my base A6 2.56 geared car.... At the 2008 Corvette Forum Cruise In I ran a string of 12.5's . The car was brand new and just turned 500 miles as I went through the gates at Beech Bend... The engine was heat soaked from the 100 mile drive there. It was a hot and humid day and I ran with all the nannies on...
