What platform was the Chevy SS?
The Chevy SS was built on GM's rear-wheel-drive Zeta platform.
From 2013 to 2017, Chevrolet's SS used the Zeta-based chassis derived from Holden's VF Commodore, assembled in Australia and then exported to the United States as a Chevrolet performance sedan.
Platform identity
Key facts about the platform that underpins the Chevy SS are summarized below.
- Platform name: GM Zeta platform (rear-wheel drive).
- Origins: Derived from the Holden Commodore VF generation, produced in Australia.
- GM family: Also used by the Pontiac G8 (2008–2009) and other Holden models, sharing architecture across GM divisions.
- Layout and design: Front-engine, rear-wheel-drive layout with a unibody chassis designed for performance sedans and wagons.
- Production details: The Chevrolet SS was assembled at Holden's Elizabeth plant in South Australia before being exported to the United States.
The Zeta platform provided a scalable, rear-drive architecture suitable for V8 power and balanced handling, enabling GM to offer a true performance sedan in the U.S. market.

This platform served as GM's backbone for several regional models, illustrating how global platforms enable cross-market product strategy.
Relation to Holden and U.S. market
What this platform means for production and market access is explained below.
- Global lineage: The VF Commodore in Australia used the Zeta architecture, with the SS U.S. version tuned for Chevrolet branding.
- Cross-brand sharing: The G8 (Pontiac) and the SS (Chevrolet) both relied on the Zeta underpinnings, reflecting GM's regional adaptation of a single platform.
- Lifecycle context: The Chevy SS was produced for the U.S. market from 2013–2017, with GM subsequently ending the model as part of a broader brand strategy.
In short, the Chevy SS stands as a rare product of GM's global platform strategy—an American sedan built on an Australian-designed Zeta platform.
