Zeta is the original name for General Motors' full-size rear-wheel drive automobile platform. The architecture was engineered by Holden of Australia and is now referred to as the "Global RWD Architecture". The GM Zeta platform has replaced the V-body, and will replace the W-body after 2010.

[edit] Development
Development was started in 2000 by Holden of Australia in order to replace the aging V-body platform underpinning their Commodore VX after sister division Opel announced the production and design would end on the Opel Omega (on which the Commodore was based). Principal development on the VE Commodore was completed by July of 2004 at a cost of approaching AU$ 1,000,000,000 and the first testing mules underwent trials later that year. General Motors global corporate headquarters took notice of the VE design and began studies on the utilization of the underlying architecture (internally christened Zeta by GM engineers) for a range of future products on a global scale. The idea of Zeta as a global platform was officially revived when GM announced the future Camaro would use the Zeta platform.
[edit] Features
The Zeta architecture is very flexible and can accommodate a wide divergence in automotive design features such as wheelbase length, ride height, windshield rake and roof line without adversely affecting chassis rigidity. Zeta's suspension system is all wheel independent and utilizes a MacPherson strut coupled with a dual ball joint lower A-arm for the front and a four link independent setup for the rear wheels. The engine is mounted slightly behind the front axle giving improved weight distribution.
