Pontiac G8: 2008–2009 rear-wheel-drive sedan with V8
Pontiac G8 — a rear-wheel-drive sedan built in Australia on the Holden Commodore platform and sold in the US as Pontiac. We look at the V6, V8, and GXP versions, how they differ, and what to check when buying a used G8, often imported from the US.
G8 in brief
The G8 debuted in 2008 and was sold for just two model years — 2008–2009. It was one of the last Pontiac sporty sedans before the brand was discontinued. The car was developed in Australia based on the Holden Commodore (VE).
Thanks to its rear-wheel drive and powerful engines, the G8 is beloved by enthusiasts, especially the V8 version. It's rarely seen in Lithuania and almost always imported from the US.
V6, GT, and GXP — what's the difference
The base version of the G8 comes with a V6 engine and more modest equipment. It's the most affordable, but still offers rear-wheel drive and a sporty driving feel.
The G8 GT features a V8 engine and a more aggressive look, while the G8 GXP boasts the most powerful V8 with a sport-tuned suspension and additional features. Due to its power and rarity, the GXP is highly valued by collectors and enthusiasts.
Engines and transmissions
The G8 offers a 3.6-litre V6 (around 255 hp), a 6.0-litre V8 (around 360 hp), and in the GXP version, a 6.2-litre V8 (around 415 hp). These are fairly large engines, so fuel consumption is high, especially in the V8 versions.
The transmission is usually automatic (five or six speeds, depending on the version), and the GXP also offers a six-speed manual. Power is sent to the rear wheels.
What to check when buying a used G8
Before buying, check the VIN history and documents — the car was imported from the US or another market, so it's crucial to know if it hasn't been in an accident and what the true mileage is.
Test the automatic or manual transmission, steering, suspension, and brakes. Check the engine sounds and oil leaks — larger V8 engines require meticulous maintenance.
Parts availability in Lithuania is limited, but some mechanical parts are shared with other GM vehicles. Consider where you can service the car.
