The Pontiac G8 is a rear-wheel-drive, four-door sedan to be made by Pontiac as a 2008 year model vehicle and is also known as the Holden Commodore in Australia, the country of its origin. It is the sucessor to the Pontiac Grand Prix and Pontiac Bonneville. It was a shortlived model following GM's announcement to phase out the Pontiac brand by 2010. This was a replacement for the GTO
