Someone help me understand how a C7 Z51 that weighs more than a C6 Z51 goes as fast as a Z06 (that is lighter than both of 'em) 0-60, with 55 LESS horsepower than the aluminum framed Z06.

WTF, over ?

OnPoint

As fast as, might be a bit strong, but it's pretty close in performance, so I get your point.

Answer is torque, gearing and traction. And the VIR time speaks to the chassis and handling capabilities.

The variables are enormous this is not hard maybe make a list of them


Over

The 0-60 test is really pointless and tells very little about overall power. What's likely going on here is: the C7's tires have more grip and therefore can provide a better platform for launch. Also the C7 has a slight rearward weight bias (woo hoo!) which will also help with the launch.

JustinStrife

Yes because weight and power are the only factors involved...

First it's 45 hp less and only 5 FT LBS (w/NPP) less tq. The rest is traction and suspension.


“The new Stingray constantly communicates feedback to the driver, which makes you feel incredibly confident behind the wheel,” said Jim Mero, Corvette vehicle dynamics engineer. “That confidence encourages you to attack each corner because the Stingray drives so well: the tire grip is incredible; the steering response is some of the best I’ve ever experienced; the Magnetic Ride dampers allow little body roll through the corner, while still soaking up the rumble strips when you clip the apex,” he said. “It’s just addictive on the track

It doesn't. According to GM, C6Z 0-60 is 3.5 sec.

Computers...same way the GTR is faster than the ZR1

DREAMERAK

Unless they are on a road course, then the GTR is slower.

All new motor, may have something to do with it.

3.7 according to GM, lets keep it apples to apples.

We had these same threads when the GTR debuted and posted numbers that seemed other worldly and give C6 Z06 owners fits. Technology is a beautiful thing: more with less.

0-60 it's faster

OK - pay attention:

First you get yourself some thick white smoke - then you're gonna need several very large mirrors - with practice and using said devices, you can make almost anything appear to be/do anything . . . also good on occasion to signal the election of new Pope

OnPoint

As it is on a roll or in the standing mile.

0-60, tho is a different matter and it takes a very good ZR driver to handle a GTR off the line.

Minkster

Apples to apples (1st yr to 1st yr), those numbers I posted were from GM’s initial 2005 test as stated in the table for the first year C6Z (2006). However, after some digging, I found GM's 2006 Z06 Performance Numbers announcement, and it is 3.7 sec 0-60. Anyhow, last I understood of mathematics, 3.7 is lower than 3.8.

What will be interesting is what numbers the car mags and internet testers come up with.

JoesC5

GM has to provide numbers that show their latest is better than what it replaces.

For example, GM said the C5 coupe has a .29 Cd.

They had to better that with the C6, so GM says the C6 coupe has a Cd of .287.

But, Independent tests of both the C5 and the C6 in a wind tunnel in NC that is used by the NASCAR teams(and others) showed that the C6 actually has a higher Cd than the C5 and neither one of then were below .33 Cd.

Guibo

Different wind tunnels could yield different results. A static one might be different from one with rollers in which the aerodynamic forces of wheel motion might come into play. Sport Auto put the C6 inside of DiamlerChrysler's wind tunnel, which they do for all of their supertests. That C6 recorded a Cd of 0.29, which is below 0.33 and close enough to the claim.

~Stingray

This is very misleading. The GTR is "faster" from 0-60 because of the AWD; it can put the power down quicker than the corvette which only has two power wheels. But go beyond the quarter mile and engage in racing with turns and stretches longer than 2000 ft and the GTR takes a very far back seat to the corvette.

Bat Man

The GTR is easy to drive in the twisties due to the computer doing all the work.

To say it takes a "very far back seat", that's absurd.
