The 2008-2009 Pontiac G8 and G8 GT were a powerful and stylish pair of rear-wheel drive sedans that marked a significant departure for Pontiac. These Australian-built machines were based on the Holden Commodore, a platform renowned for its robust construction and performance-oriented nature. The G8 was offered in two flavors: the standard G8, which boasted a 3.6-liter V6 engine generating 256 horsepower and 220 lb-ft of torque, and the G8 GT, which came equipped with a potent 6.0-liter V8 engine producing a thrilling 361 horsepower and 387 lb-ft of torque. Both the G8 and G8 GT were offered with a six-speed automatic transmission that delivered smooth and responsive shifts. The G8 GT, in particular, stood out with its impressive acceleration and cornering capabilities, thanks to its powerful V8 engine, well-tuned suspension, and rear-wheel drive setup. The G8 and G8 GT were praised for their comfortable and spacious interiors, featuring high-quality materials and modern technology. They provided a premium experience that rivaled luxury sedans of the time. Unfortunately, the G8 and G8 GT's tenure was short-lived, as Pontiac was discontinued by GM in 2010. Despite their brief time on the market, these two models remain iconic in the annals of Pontiac history, representing the brand's commitment to performance and style when it was still around.
