So, how many vehicles are we looking at from Zeta?

Chevrolet: Camaro, Monte Carlo/Chevelle, Impala, El Camino
Buick: Roadmaster? And coupes?
Pontiac: GTO, G8/Grand Prix
Cadillac: ?
SAAB: ?
Holden: Pretty much their entire RWD lineup?

 

How do you fit the finger into the fax machine? Or do you have to UPS that baby?

 

I've hear rumours that it's possible the Zeta Platform may come in two forms(a LWB & a SWB). This actually could be true it one considers that Lutz stated the the Zeta Platform is capable of being used for a wide range of applications.

Now we've already seen the SWB version of the Zeta in the Camaro Concept

But a long wheelbase version may be about the same size as the CTS chassis(about 113 inches)

Here's what I think is possible.

Chevy
Camaro - (SWB) Zeta Performance(Pony car) Coupe
Impala - (LWB) Zeta Performance Sedan

Pontiac
GTO - (LWB) Zeta Performance(Musclecar) Coupe
Grand Prix/G8 - (LWB) Zeta Performance Sedan

Buick
Roadmaster - (LWB) Zeta Performance Sedan

Holden
Most of the large RWD line - including a coupe, sedan & sport truck.

No Cadillac model will likely get the Zeta Platform. As Cadillac mostly uses the more expensive Sigma Platform, now. A Platform that is perfect for GM's Luxury line.

 

There may be more than just a SWB/LWB distinction with Zeta. Holden uses a SWB for it's standard sedan and coupe models, and the LWB for wagon, ute and luxury sedans. If the Camaro is to roll on a shorter lenght than the Commodore, then there will need to be three wheelbase lenghts to cover the known models.

 

It's not simply only wheelbase. Compare the Camaro concept and some of the VE Commodore spy pics. Note the difference in dash to front axle lengths for example.

Compared to the previously cancelled Zeta GTO/Chevy coupe, the Camaro has some length taken out of it's midsection and perhaps alittle longer dash to front axle length.

 

Lutz mentioned in the OP that the dash to axle length was easily changed (I'm sure easy is a relative term here)

 

From the dash forward, Camaro has a completely unique structure compared to the sedans. It appears that they will ALL share the same tall cowl heights, however.

 

I think the floorpans are more expensive to make than the rest of the car, so I'd imagine there's probally 2 wheelbases along with length extentions (front & rear) to change length.

Finally, the "firewall" (thermal event separator for the people who cringe at that term) seems to be a non-factor here, and theres going to be differences in the firewall to front wheel distances between different Zeta cars.

The underhood arrangements and surrounding structure are actually going to be the same to simplifiy crash tests and keep cost down.

These cars seem like they are going to be the "Lego" of car construction. The technical articles on this chassis should be very intresting reading.

 

in simplistic terms......think of Zeta as a Boeing 737........there are several lengths. (very simplistic, mind you.....Boeing 737s pretty much all look the same.....)

I think you have too many coupes listed!

(hint: people tend to refer to a platform as "Impala/Monte Carlo".....)

 

 

Ahhhhhhh d@mnit.... add some winkys while your at it.

You guys are gonna give people an anxiety attack.

In all seriousness I really enjoy the slightly more open speak that's apparent these days, than say a year ago. I appreciate the hints even without the use of winkys.

Definitely good times, now when can I buy?

 

So is an El Camino considered a coupe???


Wasn;t it indicated that Buick was just going to get a Sedan, and not a Coupe???

Ok, thats all of the coupes that I want eliminated (and I wasn't counting the El Camino as a coupe )

 

FedEx Overnight.....trust me.

 

OK, Digit.

 

Hmmmm. A "Impala/Monte Carlo" platform....
.......different lengths....like a 737.....
.....Camaro coupe.........
..... a confirmed GTO......
...but too many coupes......

There's so many hints and clues in that post, I'm surprised someone's head hasn't exploded yet.
