This is the Australian Holden Commodore GS HSV which is basically a Pontiac G8 with a supercharged LS3. There is a standard LS3 version too badged as the Commodore SS. Rumor has been that the G8 would return to the US with Chevy badging. The dots might connect to this rumor. I spend a lot of time down under and have friends that work at Adelaide Holden (dealership) who have confirmed the rumors of this beast hosting a Chevy badge as early as 2014. View my photo album to see the red SS.
