Holden's model line-up consists of re-badged Chevrolets, like the Spark, Cruze and Volt, and larger brand specific models like the Ute, commodore and Sportwagon. The Commodore is imported to the US as the Chevy SS.
With the SS being the only (NOT!!!) model that will be affected outside of Australia, will Gm just give up on the SS, or will they move production to another facility to continue selling the model?
Well, what you say is not entirely true--there is the Middle East business (no idea of the size of that market segment, or whether the new Impala is being pushed now, but Holden cars have been in vogue there since the demise of the US-built Caprice and Caprice SS in 1996), and there is the current (US) Chevrolet Caprice PPV business--a segment long abandoned by GM, only to be given the short-straw treatment by this pending Holden "death" decision, after MAYBE 5 or 6 years of production (2011-2015/6?).
Probably doesn't matter, as PPV business seems to be shifting to SUV's, with the 2015 Tahoe PPV due next year with it's version of the
GenV direct-injection 5.3L engine (Ecotec 3) with 355 HP (click on menu on right side of screen - 2014 Product Guide).
The Caprice PPV V8 (L77 6.0) is also rated at 355 HP, with equal torque to the smaller L83 5.3 DI engine, most likely due to the higher CR with DI of the Ecotec3 version--in other words, I could replace my L77 with an L83, keep the same overall performance, and bump the FE numbers a couple of MPG--ain't technology grand!!!
As to the idea of moving production of Zeta platform to a suitable location, I'm guessing that the current iteration will cease to be relavent once Camaro is an Alpha, and the exclusiveness of the new ATS/CTS platform is finally shared with the other divisions, that will set the future for something to follow Zeta.
We may want to be careful about what we wish for, as one thing that COULD happen would be that Zeta build could shift to China (as Holden or Chevrolet), where the Buick Park Avenue is currently assembled and sold as a captive model (a
CKD shipped in from Oz, as I understand it)--who would be willing to buy a car built in China, even from "GM"??? I'm guessing there would not be much enthusiasm for that option.
I have no basis in fact for saying this....just letting the imagination run with options that GM could choose to explore--not sure China is ready with workers of the skill level to make a world-car factory run reliably and/or produce an acceptable product. They have plenty of warm bodies to choose from, however!
While I wouldn't put anything past current top-level GM management (CEO Akerson), the issues that such a move would create could make quite a mess. His tenure should be over before too much longer, just hope he isn't able to do much more damage.
