Based on the Holden Commodore and the new global RWD platform Zeta, Pontiac moves one step into its revitalization. It comes with a 261 HP 3.6 V6 and a 362 HP 6.0 V8 with AFM( Active fuel Management). The 3.6 V6 is mated to a 5 speed auto and the V8 is mated to a 6 speed auto. A 6 speed manual will be offered later after production starts. Production is along its Commodore sibling in Australia( Note: It will move to NA eventually and possibly at GM's Oshawa plant in Canada). What you see is pretty much the production version. Besides some things like the 20" wheels, the interior trim color, etc.
