Silly question, why didn't GM just sell the US-Spec Commodores as Chevrolet models right after dropping pontiac rather than waiting until last year to sell the Commodore here again? Not enough of a market?
The change from the VE to VF Commodore was a big part of it. Alterations to the look inside and out, in addition to fuel-saving enhancements were all a part of the deal. Granted, the SS is the equivalent to the HSV Clubsport, but shares more of its bodywork with the more standard VF Commodores.
The problem with going downmarket on the Commodore would have been significant product overlap, depending on which version of the Commodore would have shown up. Something like the Commodore Evoke would have been a halfway decent starting point, but probably would have diluted what the SS is (ie, a luxury performance sedan), and
probably would have been a big dent in potential Impala sales. If they would have stuck with the idea of bringing over a V6 Commodore, something like the Calais would have made a lot more sense by making it a luxury V6 sedan - but again, that would have overlapped with not just the Impala, but also the LaCrosse,
and potentially even the SS. Even thinking of it this way, how would you market what is otherwise the SS sedan, but with a V6 - and what would you call it?
I definitely think there's a market for something like a large, rear-drive, near-luxury sedan from GM in the States. Absolutely. Coming from Chevrolet, the jury is out. I love the current Impala, and would love to see Chevrolet have a premium sedan to offer to potential luxury buyers. But, the reality is that, as a Chevrolet, its a tough market for anything above $45k. Now, as a Buick? That'd make a lot of sense. Shoehorn the 420 BHP 3.6T under the hood, you've got yourself a modern-day GN.
...So, we'll see. The Zeta chassis is on its way out, there's no telling what'll happen when the Alpha chassis takes over for some of these models.
