If you want to be technical about it, most Commodores aren't actually a Commodore. Holden for a long period of time never actually had a name for the whole model range, just a code (HQ, VB etc), with the base or common model often becoming the "generic" name (ie Kingswood, Commodore). Before Kingswood you had the Standard, Special and Premier, for the Kingswood you had Belmont, Kingswood and Premier, for the Commodore (VK onwards) Holden were less serious with the naming style but you still have Acclaim, Berlina and Calais as standalone names (for instance you don't see a Commodore badge on the back of a Calais, it literally is a Holden Calais). And to make this relevant, you could apply the same naming scheme to the Camry/Aurion :P They share the same chassis code, under the skin they are essentially the same car sans engines and cosmetic head/tail-lights. If you think of it as the Toyota XV (using the chassis code as a model code like Holden), then your 4-cylinder models are Camry Alise/Ateva etc and your 6-cylinder models are Aurion ATX/Sportivo etc
