Zeta was the original name for General Motors' full-size rear-wheel drive automobile platform developed by GM's Australian subsidiary company Holden and was most recently referred to as the "Global RWD Architecture". The GM Zeta replaced the V-body, and debuted with 2006 Holden Commodore (VE) sedan and utility. This platform was considered as the replacement for the North American W, H, and K platforms until plans were cancelled due to fuel-economy considerations and GM's financial situation. Although the future of the Zeta program was in doubt at that time, in May 2009, Holden began the development of an improved second version of the platform that went on to form the basis of the 2013 Commodore (VF) and Chevrolet SS.[1][2]

The 2010-15 fifth generation Chevrolet Camaro was the only Zeta platform model produced in North America. All other Zeta platform vehicles have been manufactured in Australia by Holden. In 2016, the Chevrolet Camaro (sixth generation) debuted on the GM Alpha platform.

Australian manufactured models include the long-wheelbase Holden WM Statesman/Caprice sedan and the high performance range produced by Holden Special Vehicles. On export markets, Holden-based models included the:

In December 2013, Holden announced that it will cease its local production by 2017 and, with it, the production of the GM Zeta platform. As of 2017, the Zeta platform was no longer in production.

Development

Development was started in late 1999 by Holden to replace the aging V-body platform underpinning the third generation Commodore that debuted in 1997, after Opel announced that its Omega (on which the Commodore was based) would be discontinued. Principal development on the VE Commodore was completed by July 2004 at a cost approaching A$1 billion and the first testing mules underwent trials later that year. General Motors global corporate headquarters was impressed by the VE design and began studies on using the underlying architecture (internally christened Zeta by GM engineers) for a range of future products on a global scale. After the cancellation of the plan due to the fuel-economy considerations and GM's financial situation, the idea of Zeta as a global rear drive platform was revived with plans for the fifth generation Chevrolet Camaro of 2010.
