Story

2008 Pontiac G8 GT

The 2008 G8 GT brought Pontiac's performance-sedan identity to a rear-drive, Australian-built platform sold through the North American program. The accepted GM and DOE/EPA records establish the model-year identity, V8 application, 6.0-liter displacement, automatic transmission, and rear-drive layout.

This page represents the reviewed G8 GT program without extending its facts to the later GXP. Horsepower, torque, axle ratio, and option detail remain explicit gaps until exact factory literature is reconciled.

Evidence boundary

The licensed exact-year exterior supplies representative visual context only; it does not establish an individual car's originality or equipment.
