Model overview

The Pontiac G8 is a full-size sedan that was built by Holden in Australia, and then exported to the U.S., where it was marketed by Pontiac. The G8, a rebadged Holden Commodore, debuted in 2008 for the 2008 model year in the U.S. Making ceased mid-2009, following the GM resolution to suspend the Pontiac brand. The G8 was Pontiac's prime full-size vehicle since the GTO coupe and Bonneville were sold back in 2006.

With the cession of the Pontiac brand, an outcome of GM's Chapter 11 bankruptcy, 2009 was the last model year of all Pontiacs, including the G8. To satisfy the gap left by the G8, GM announced the Chevrolet SS, a rear wheel drive V8 powered sedan for the 2014 model year.

The Pontiac G8 is available in base, GT or GXP trim. The base is powered by a 3.6-liter V6 engine that delivers 256 hp and 248 pound-feet of torque. The power is sent to the rear wheels through a five-speed automatic transmission with manual shift control. The GT has a 6.0-liter V8 engine with 361 hp and 385 lb-ft of torque that's paired to a six-speed automatic. The GXP's 6.2-liter V8 with 402 hp and 402 lb-ft of torque can be paired with either the GT's six-speed automatic or a six-speed manual transmission.
