I been away for a while, but since I cant find anything else about the G8, I'll put it here (feel free to move if needed admin :))

Whats different about the G8 compared to the VE Commodore?

-Unique front bumper with Pontiac signature twin nostril snout.
-Different lower air intake, with centre spine and driving lights.
-Exclusive Pontiac bonnet (that you wont see on a Commodore because it matches Pontiac grille)
-18" wheels on G8, 19" on G8 GT.
-Commodore SS-V tail lights
-subtle bootlid spoiler
-Active Fuel Management on V8's (DOD)
-194kw High Output V6, might get 225kW direct injection V6 at later stage.
-G8 has 5L40 five-speed auto standard
-G8 GT has 6L80 with the option of manual transmission

Entry level G8 will cost around US$25,000
G8 GT will be around US$30,000

Estimates of VE's exported as G8's will be somewhere between 20,000-50,000 depending on market.
