General Motors has revealed the 2008 Pontiac G8 sports sedan. Based on the Commodore from GM’s Holden subsidiary in Australia, the G8 will serve as a replacement to the aging Grand Prix.
The base model features a 261 horsepower 3.6-liter V6 with 250 pound-feet of torque. A more powerful G8 GT delivers 362 horsepower and 391 pound-feet of torque thanks to a 6.0-liter V8.
The basic G8 features a five-speed automatic with manual mode, while the GT version is offered with either a six-speed automatic or six-speed manual gearbox.
Curb weight for the V6 model is 3,885 lbs, while the GT weighs just five pounds shy of 4,000. 18-inch wheels come standard, while 19-inch alloys can be ordered with the GT model.
The sedan rides on GM’s new Zeta rear-wheel-drive platform, which underpins the 2009 Camaro and the next-generation Impala, in addition to several other planned vehicles.
G8 deliveries are expected to begin in August — a relatively short lead time made possible by some very effective badge engineering.

Wow, the Pontiac G8 GT looks like a beast with that 6.0-liter V8! 🚗💨
Is the six-speed manual gearbox smooth enough for everyday driving?
Can’t believe they’re still using a five-speed automatic in 2008. Feels a bit outdated, don’t you think?
The G8 seems to have borrowed a lot from the Commodore. How different are they really?
Why did they choose to replace the Grand Prix with this model? 🤔
Badge engineering” sounds like a fancy term for recycling old designs. Is it? 🤨
I’m thrilled to see a rear-wheel-drive platform! That’s going to be fun to drive. 😄
How does the fuel economy compare to other sedans in its class?
Thank you for the detailed specs! I’ve been waiting for this release. 😊
What’s the expected price range for the base model vs. the GT?
The new Zeta platform sounds promising. Does it improve handling significantly?
