General Motors Zeta platform

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 at one stage referred to as the "GM Global RWD Architecture". The GM Zeta platform replaced the V-body, and debuted with 2006 Holden Commodore (VE) sedan and Holden (VE) Ute. 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.

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:

short-wheelbase Commodore (VE)-based Pontiac G8 and the Commodore (VF)-based Chevrolet SS (for North America)

full HSV range (for New Zealand and Singapore), the HSV-based Vauxhall VXR8 (for the United Kingdom) and Chevrolet Specialised Vehicles (CSV) E-series (for the Middle East)

the long-wheelbase Chevrolet Caprice PPV and the Buick Park Avenue (the latter exported to China as a Complete knock down (CKD) kit).

In December 2013, Holden announced that it would cease its local production by 2017 and, with it, the production of the GM Zeta platform. Production ended in October 2017.
