2005 Pontiac G6 Review

Plenty of space and unique styling.

Reviewed by Automotive on


Pontiac kept the aging Grand Am for a long time. At some point, it became clear that the time had come for some new blood in the company’s lines of midsize sedans. As a result, the G6 was born for the 2005 model year. This car didn’t take long to impress the auto industry leaders and start to make a name for itself among the new Pontiac car buyers of the time.

The Range

Body Styles: sedan
Engines: 3.5-liter V-6
Transmissions: four-speed automatic
Models: Pontiac G6 Base, Pontiac G6 GT

What's New

For the 2005 model year, the Pontiac G6 is offered brand new to replace the seriously-aging Grand Am.


There are certain things expected from a Pontiac in terms of its appearance, and the new 2005 Pontiac G6 fits the bill. This car offers the style and sporty look Pontiac is famous for, while updating the aging sedan body style. The G6 features clean, crisp lines, modern accents, and bold, assertive looks. This car was fortunately designed without the plastic pieces that so marred the appearance of the later versions of the Grand Am. The G6 is available with a unique sunroof option that opens four ways and creates a roof spoiler effect when opened. This feature gives the G6 a rather European look.


As exciting and interesting as Pontiac has made the exterior of the 2005 Pontiac G6, the interior is impressive as well. This very large cabin features attractive seating with side bolsters to ensure driver and passengers stay in place around corners, twists, and turns when taken aggressively. The cabin is accented with chrome and metal trim throughout. This material can be seen around the dash gauges and in other places within the cabin. For the most part, the materials used in the cabin are good, but there are few pieces here and there that are a bit cheap and distract from the overall comfortable environment of the cabin.

Inside the cabin, there is no denying there is plenty of head and leg room, unless the car has the optional sunroof. This feature does reduce the rear seat head room pretty dramatically.

Performance & Handling

The G6 offers a 3.5-liter, V-6 engine capable of 200 hp and 220 lb-ft of torque. When coupled with the four-speed automatic transmission with manual shifting abilities, the drivetrain provides a comfortable ride with enough power to make the G6 notable on the highway. Regarding the powertrain, it should be noted that the G6 does act a little peculiar when pushed to faster revs. Overall, the G6 performs very well and offers incredibly crisp handling.

With its solid structure and secure suspension, the 2005 Pontiac G6 is sportier than one would expect and offers a comfortable, peaceful cabin ride. The V-6 engine is more than capable of keeping up with merging and passing traffic on the highway and does well in the city, too. It does seem to get a bit too excited when pushed to high speeds, however.


Pontiac adds some impressive safety features to the 2005 G6. This car offers four-wheel disc brakes. The GT edition is available with standard traction control and anti-lock brakes, though those features were only offered optional on the base model. Side curtain airbags were available optional on either trim level. Pontiac does not offer stability control in any form for this model.
