The Pontiac G8, produced from 2008 to 2009, was a rear-wheel drive full-size sedan that offered a compelling blend of performance, luxury, and value. Built on the Australian-developed Zeta platform, the G8 shared its underpinnings with the Holden Commodore, a popular model in its home market. This shared heritage resulted in a car that was both spacious and agile, with a well-balanced chassis and a refined driving experience.

The G8 was available with a choice of two powerful engines. The base engine was a 3.6-liter V6 that produced 256 horsepower and 248 lb-ft of torque, providing ample power for daily driving. The more potent option was a 6.0-liter LS3 V8, borrowed from the Chevrolet Corvette, generating a thrilling 400 horsepower and 415 lb-ft of torque. Both engines were paired with a six-speed automatic transmission, delivering smooth shifts and efficient performance. The G8 was also offered in various trim levels, ranging from the well-equipped base model to the luxurious GT and sporty GXP, each featuring distinct styling cues and performance enhancements.
