Not as much of an issue as some have made of it.

Several years ago, when Caddy was considering a smaller 3-series competitor, GM re-engineered a version of Sigma with a lower cowl.

The only roadblock to a Sigma based Camaro.....which could be made into a proper Camaro......is politics, pure and simple.

 

Don't know why it couldn't be......

 

Wait...
A Sigma based Camaro would get us a proper Camaro, yet a Zeta based Camaro using the same basic suspension set up as Zeta would NOT get us a proper Camaro?

I, for one, dont find this news interesting, just annoying. First Zeta was gunna be an updated VZ chassis, and wasnt the cheap version of Sigma. Then its "oh well, Zeta might have 2 different suspension set ups and it might be mroe Sigma then Omega"
Now it seems as if Zeta is the replacement for Sigma
Sigma and in turn, Zeta was going to have too high of a cowl to give us a proper Camaro. Now, that was all bs.
Sigma was too expensive to make a mass production car.
I didnt find it weird that the STS is on a longer and wider Sigma chassis, that also sits under the CTS, neither do I find it odd that the SRX is sitting on basicly the same chassis.
I guess that when we thought that Zeta might have 2 different suspension set ups, what was really going on was testing of the two, and the Simga model won out (duh).

 

Lots of stuff is COMPLETELY up in the air as we speak. At this point...maybe nobody knows how it will shakeout.

But one thing that I can guaranfreakintee you is....the architecture that we have known, up till now as "Zeta"....will NOT replace Sigma.

The opposite is more likely.

 

It's unbelieveable how all of this isn't even figured out yet. 07/08 is getting closer and slow GM is still in confusion about these things.

 

We're going in big circles now...

 

I was wondering what ever happened to such thoughts. With knowing sigma supports options for width, length, and firewall height, that might make the platform flexible enough to accomplish a lot more. If that's the way things are going (and Zeta gets the axe in NA) then that would mean GM is going fleb-platform-crazy like Nissan did. Granted, sigma is a good chassis, but I wonder how this would effect the big picture.

It sucks that we're going in circles though...

Either way, I think it'd never have been possible to get a new Camaro before 2007. Political nonsense out the wing wong.

 

First thing that came to mind when I read that was that we know jack sh*t about zeta, so how can what we 'know' be dead if we don't know anything?

As with guionM's post, it seem to me nothing has changed in the last 2 odd years. Zeta is still based on Sigma, see here for an old thread on that. And is designed with flexability in mind. But now it may take over from Sigma in the future.

The more things change, the more they stay the same.

 

Well, I don't know about that.
We're in the middle of some pretty big changes. The Holden/North America experiment may be over.

 

Why is that?

No offense, but all the little one-liners, and then not being able to elaborate on them get frustrating sometimes....

 

I've been mentioning "why" for months...

Holden has a different way of doing things, a different bill of process. North America cannot build what Holden designs. If we are going to ultimately have a "global" RWD architecture, Holden will eventually have to build what GMNA engineers...not the other way around.

 

But, wouldn't this problem be glaringly obvious before any talk of a shared platform even started with GM?

How could they be literally YEARS into a shared platform and then realize it wasn't going to work because of something like this?

I know GM has a lot of red tape and the whole "it takes a long time to turn a big ship" things, but I simply can not believe something so basic could be overlooked for so long... you'd think that MILLIONS of dollars would have been wasted here.

What exactly is so different about the process between Holden and GMNA?

 

This is all speculative b.s.

I am sure that we will have RWD V8 sedans and coupes(a RWD Chevy coupe ) by the end of the decade. I am also sure that GM has been working on this for quite a while and will not push the delivery date back.

I don't think anybody knows exactly what they are talking about in this rumor mill. The reason things are so speculative is that GM has to keep everything under a security lockdown to keep spies from other companies from stealing their info.

 

I'll go on a limb here and say Zeta will not replace Sigma for the sole purpose of politics as Z's mentioned. Sigma is exclusive to Cadillac for a reason, and that reason is exclusivity. Cadillac will not share it's world class architecture with a Chevy Camaro, imagine how that would reasonate with 50 year old white hairs.

Also, we have something very special in '08 that's Sigma based. I don't see Sigma going anywhere for quite sometime, and certainly not before the end of the decade.

 

There has been a bit of misinformation going around the last few months. I'm not saying this is part of that (I honestly don't have a clue what Z28 is talking about). It is going to be another 8 months-1 year before we really know what is going on for sure.
