GM's RWD architecture will downsize and survive

General Motors may be lacking the cash to develop any new rear-drive platforms, but reports out of Australia suggest that the existing Zeta platform that underpins such models as the Holden Commodore and new Chevrolet Camaro will carry on for at least another decade.

GM's Australian subsidiary only finished development of the current Zeta platform a few years ago, and it's not about to flush that down the toilet. However the next Commodore, currently sold in the North American market as the Pontiac G8, is likely to downsize for the next generation, anticipated to debut in 2013 and carry on through 2020. Along with the reduced size and heft, the General could use smaller, more efficient, though still powerful engines, employing direct injection and/or turbocharging like the Cadillac and Saab variants of the V6 already used by Holden. As we've discovered with vehicles like the Pontiac G8, GTO and the new Camaro, what's good for the Australian market is, in General Motor's eyes, good for North America, so fans of rear-drive American muscle have some hope to hold onto yet, mate.

Well that's about as clear as mud.

Sounds good, but...

Hmmm...Zeta morphs into Alpha...from Z to A...?

As long as it comes over here as a Pontiac I'm all for it. Call it Torana, Tempest, G8, or G6, I don't really care. I'll take one with a turbo V6 if they can't fit a V8.

Very hard to tell from this article, the information needs major clarification.

I had offered the suggestion in previous posts that the next gen Commodore and Statesman could be downsized in an effort to create smaller, lighter, more fuel efficient RWD vehicles. The next gen Commodore could be downsized into a RWD midsized sedan thats about 190 inches long on the current car's 114.7 inch wheelbase; this car could be brought here as the Pontiac Grand Prix (because Pontiac needs to get rid of the ridiculous, meaningless, sterile G-numeric model designations, like yesterday). A turbocharged version of the 2.4 DI 4-cylinder could serve as the base engine and the 3.6 DI V6 could serve as the optional engine (a GXP version could be fitted with a turbocharged 3.0 DI V6). The next gen Statesman could be downsized to 197 inches on the current car's 118.5 inch wheelbase (which would make it roughly the size of the current Commodore); this car could be brought here as the Pontiac Bonneville. The 3.6 DI V6 could serve as the base engine and a turbocharged 3.0 DI V6 could serve as the optional engine (a GXP version could even be fitted with a small block V8). That would be the extent of Pontiac's future niche lineup: 2 affordable and fun to drive RWD sedans. Buick can stick with FWD as well as the Opel based products.

GM can also use this version of Zeta for the next CTS (CT5?) car series as well as a DT7 flagship sedan for Cadillac. An AWD compact car series (AT3?) could then be developed on the Theta-Epsilon (or Theta Premium) platform if Zeta can't accommodate a compact car series.

GM just needs to commit to something and make it happen. The corporation has the platforms and other raw materials available to form some coherent product strategies.

Oops! I forgot what today was...

The article doesn't come off that way.

If it is, then it's in very bad taste and completely un-funny.

No it doesn't come off as an April Fool's joke. If you've read Autoblog throughout the day they've been posting actual news. Plus, there is always a giveaway to a fake...something is always amiss. This doesn't come off that way.

True or joke, its not very well written. I'd be inclined to believe there is something to it, its not a April Fools prank.

With GM's lack of money it may be wise to just adapt the Zeta to a smaller platform. Much of the engineering work would be done. The only things needed to be done is to scale down the car in size and weight.

If it ain't broke adapt it.

Just think of the time and money that could be saved. This could move the program up a year at the least.

The question is will shrinking the size along get the weight down to where it needs to be to replace a Alpha?

Keep in mind the Zeta also will support AWD. This is a Holden need.

I think it's for real. Why else do you think PCS jumped ship to BMW? Holden won out. :smilewide:

Wonder if the G8 wagon will be back on, or if it will cross over to Chevrolet showrooms. Honestly, why doesn't GM replace the Impala sooner rather than later with a badge-engineered Holden Caprice? Just swap in the Chevrolet Caprice fascias and call it a day. Stylistically, it's just a natural evolution of the current Impala design vocabulary.

Because that is easy, effective, and makes logical sense. You know GM doesn't work that way. :P

Not going to happen, GM has already said the G8 Zeta is dead in North America after this current generation, so dream on ... Not so much jumping ship as locking in my 20 year pension under GME EU rules. Now lets see if GM even survives before we go off on a pipe dream, shall we ???

It's still a beautiful thought.

Look how much better the Holden looks than the dumpy W next to it!

So obvious which path to choose.

There is just something really, really wrong in the world when some markets get a proper RWD V8 Chevy Caprice, and the US, the birthplace of the Caprice, gets stuck with an outdated FWD Impala..so wrong on so many levels..

With the U.S. Government running GM now, you'll be lucky if they let any division keep a V6 let alone a V8 ...

Well, if Holden builds it, at least it won't be so ugly!

Noice Aye Matey! I wish GM was that uncomplicated.

There will be no Caprice because GM needs to put the money into a smaller V6 car and not a large over weight car that will have a very limited shelf life.

GM is going to havr to shrink their cars so they need to start now as it will take them 10 years to complete the job with little money. GM is going to have to build for the future not the present. If they have one?
