Australia has become the test bed for many of North America's next products. Holden has been wholly responsible for creating the Zeta rear-wheel drive platform that will underpin everything from Buick's new flagship sedan and Riviera replacement to the next GTO. With any new RWD platform developed for North America, a good all-wheel-drive system will need to become an option to those in the snow belts who want more security in bad weather. The Holden Monaro (GTO here, Vauxhall Monaro in England) is now available in all-wheel-drive form, pretty much working the bugs out for the next generation of the system to hit NA shores in 2007/08. AutoExpress.com in England does a test, and loves the tech and the new body kit.
