The overview
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.

Behind the data
Latest source update: September 11, 2026
Vehicle summaries, specifications, pricing and ratings come from Consumer Reports vehicle records. Auto Guide groups these records by model and reported generation start year.
Available years are listed explicitly. Gaps do not imply that a model was discontinued. Prices are source estimates, not live offers. No first-hand road test by Auto Guide is claimed.
