Iemma has approached Holden about producing a hybrid version of the Commodore sedan which we get over here as the Pontiac G8. Toyota has been examining the prospect recently of building hybrid Camry's in Australia. Iemma has committed to using domestic hybrids in the NSW fleet if they are built. The Holden may actually turn out to be the first to produce a domestic hybrid. When GM announced the second-generation mild hybrid system earlier this year, they said the system would be compatible with rear wheel drive vehicles such as the G8/Commodore. Given the realities of fuel economy regulations, it seems almost certain that a hybrid version will debut sometime around 2010-11. If that does happen, it will likely be offered in Australia as well.
