NEW CAMARO IS GOING TO SCOOT!!! G8 GXP= REFERENCE

The G8 GXP delivers a zero to 60 mph time of 4.7 seconds, and a quarter-mile time of 13.0 seconds at 108 mph. However it weighs in at 4050 lbs!!!

thats significantly heavier than the SS!!! so we're looking at 4.2-4.4 secs o-60 and 12.5-12.8 in the quarter... .any opinions...?

Consistently. It'll get lower with the right driver.

Paper specs don't quite cut it for the Camaro. Only a couple more months (and probably less for magazines), before we can all see for ourselves.

curious what ricer math shows 200lbs giving you half a second quicker to 60, and half a second quicker in the 1/4 lol

how is the camaro going to get to 60 in 4.2, when the vette does it in 4.3?

4.5 sounds about right.

Camaro will launch better too since they "fixed" the axle hop that was noted in reviews of the GXP.

No they didn't. VE suspension is VE suspension. The nature of the IRS is to hop. You can work around it, but GXPs hop, CTS-Vs hop, ZR1s hop, and the Camaro will hop.


And I maintain that, bone stock, LS3 Camaros will be running around 12.80s at BEST.

standard vette can hit 60 in 4.0, G8 GXP hits it in 4.5, im guessing 4.3
will be the best test we see.

"VE suspension"?

And this is from a CTS-V review...
Quote:
A smooth, powerful motor and solid, quick-shifting transmissions certainly get the bulk of the credit for the impressive performance. But the asymmetrical half-shafts (one is larger in diameter) help quell the rear suspension's tendency toward hop during a fast launch. In fact, it is as hard to generate axle hop on this version of the CTS-V as it was easy to generate it on the previous generation.
When I said "fixed" (notice the quotes in the original as well) I wasn't saying that it is 100% eliminated as noone has been able to do that but it is greatly reduced. Reviewers complained about the hop in the GXP but the Camaro has the same improvements that are in place in the CTS-V and ZR1 to achieve much smoother launches.

And here's a video showing a ZR1 launch (don't see any hop)

As per the boys who built the thing (for whatever their opinion is worth )...

IRS wheel-hop has been all but eliminated on the Camaro....supposedly, GM took it down to a science, and studied resonations and vibrations that caused this issue. They've "fixed" it.

Is that a half shaft length issue or will companies have problems with wheel hop when different materials are used to hold more power?

here you go



and the camaro will def be faster than the GXP, with at least 10-15 more hp, not to mention bigger tires and eliminated wheel hop....

We were already told by a few people who tested the car (repeatedly) that it was putting down 4.6 - 0 to 60 track times. I think that's going to be about spot on.

The camaro features the New Zeta II platform...they obviously did something and im sure they tried to remedy the IRS hop...and im sure with the launch control that will help out alot as well.

From the pics there anot signifigant changes in the rear from camaro to g8. I suspect all they did was change the diameter of the halfshafts. That has worked well on the zr1 from what I have been told. That said from perviouse experience owning an IRS car. Tires make the most difference in wheel hop.

And the CTSV is not really relavant. It shares virtually nothing with either car here.

Reviewers complained about the hop in the GXP but the Camaro has the same improvements that are in place in the CTS-V and ZR1 to achieve much smoother launches.

And here's a video showing a ZR1 launch (don't see any hop)
The suspension under the G8 and the Camaro is the Holden VE Suspension. They are one and the same. Call them whatever you like, but the architecture is the same. The only difference I can tell is spring rate, damper rate, and the staggered diameter half shafts. And to say it's worked completely is fallacious, because I watched a brand new ZR1 hop through the 60', and then like hell on the 1-2 shift last year at Corvette Challenge at Englishtown. About that little video, see my comments below about WHEN you'll get wheel hop. It certainly won't happen when you're launching like a teenager and pulling 2.0+ 60' smoking the rears.

Not length, diameter. And it's too early to tell if aftermarket half shafts are going to make the hop worse.

Launch control has nothing to do with wheel hop. You don't get wheel hop from revving the car up and dumping the clutch to do a burnout, you get it when trying to launch the car and riding that fine line between power and traction. Has a lot to do with tire pressure, temperature, clutch slip.



And people, before you try and tell me what I know, go look up the "Zeta" platform. It was designed by Holden to go under their VE generation Commodore line, which launched in 2006. This is why Pedders, as an AU company with the most experience with the Holden VE, has a leg up on the competition when it comes to Camaro suspensions.
