2008 Pontiac G8

This is GM's latest attempt at bringing a rear-wheel-drive model from its Australian-based Holden division to the U.S. market. The G8 offers a 256-hp, 3.6-liter V6 paired with a five-speed automatic transmission in the base model and a 361-hp, 6.0-liter V8 with a six-speed automatic in the more powerful G8 GT. A six-seed manual is optional in the G8 GXP, which has a 6.2-liter V8. The G8 has a distinct European flavor to its ride and handling. Interior accommodations are impressive, with good seats and nice fit and finish. ESC and head-protection air bags are standard. 2009 was the final year for the G8.

Brand context

About Pontiac

Once known as GM’s performance brand, Pontiac was discontinued in 2010 along with Hummer, Saab, and Saturn. The legendary GTO of the 1960s and Firebird of the ‘70s, ‘80s, and ‘90s were joined by models such as the Grand Am, Grand Prix, and Bonneville, which were based on other GM models. The Australian-built Pontiac G8 was a legitimate muscle car, and the Vibe hatchback shared its design with the Toyota Corolla Matrix. Today, most Pontiac vehicles still on the road are more than a decade old and lack the safety and convenience features found in modern vehicles.
