2005 Pontiac G6 Convertible Dimensions, Size & Specs

The Pontiac G6 Convertible provides 61 liters (2.15 cubic feet) of luggage capacity with the rear seats in use, which is modest but expected for a convertible due to its roof mechanism requiring space. When the rear seats are folded down, the luggage capacity increases to 164 liters (5.79 cubic feet), offering considerably more space for larger or additional items, enhancing practicality during trips.

The Pontiac G6 Convertible comes equipped with tire sizes 225/50 R17 or 225/50 R18. The tire width of 225 mm and aspect ratio of 50% provide a good balance between grip and comfort. The availability of 17-inch or 18-inch rims allows for slight variations in handling and ride smoothness, with the larger 18-inch tires often offering a sportier feel but potentially a firmer ride.

Yes, the Pontiac G6 Convertible fits comfortably into a standard residential garage. Its length of 4802 mm (189 inches) and width of 1749 mm (69 inches) are within typical garage dimensions, which usually accommodate vehicles up to 6 meters long and about 2.5 meters wide. However, owners should consider turning radius and garage layout for ease of parking and entry.

At 1450 mm (57.1 inches) tall, the Pontiac G6 Convertible is fairly low-profile compared to standard sedans, which often range between 1400-1500 mm in height. This lower height enhances sporty aesthetics and aerodynamic efficiency. Compared to other convertibles, it falls into a similar height range, balancing style and comfort for open-top driving.

While exact curb weight for the G6 Convertible isn’t specified here, mid-size convertibles of this era typically weigh between 1500 to 1650 kg (3300 to 3640 lbs). This weight influences handling by providing stability at speed but may slightly reduce agility compared to lighter sport convertibles. The weight balances structural reinforcements needed for the convertible design with performance.

The Pontiac G6 Convertible shares its platform with the Pontiac G6 coupe and sedan but distinguishes itself by incorporating a retractable roof, which impacts interior and luggage space. Compared to the coupe and sedan, the convertible maintains similar length (4802 mm) and width (1749 mm), but typically has a slightly higher curb weight and reduced trunk space due to the roof mechanism. There was no direct predecessor model to the G6 Convertible, as it represented Pontiac’s entry into the convertible mid-size segment.

The Pontiac G6 Convertible's dimensions are comparable with contemporaries like the Ford Mustang Convertible and Chevrolet Cavalier Convertible. Its length of 4802 mm (189 inches) is slightly longer than some compact convertibles but typical for mid-size models. Width and height measurements align well with similar vehicles, offering competitive interior space and a comfortable open-top driving experience.

The Pontiac G6 Convertible offers enough space for small families or couples, with adequate seating for four adults. However, its limited luggage capacity of 61 liters (2.15 cubic feet) with the seats up may restrict large cargo hauling, making it less practical for large family trips. Folding rear seats increase space but convertibles are generally less space-efficient than sedans. It’s ideal for daily commuting and leisure driving more than large-scale family needs.

The Pontiac G6 Convertible’s design balances sporty style and functional size. The retractable soft or hard top mechanism affects rear storage volume and rear passenger headroom slightly. Its mid-size footprint ensures comfortable seating and maneuverability in urban settings. Wider track and moderate overall width (1749 mm) enhance stability without hindering parking ease. Tire options (17 or 18 inches) cater to both comfort and sportier handling preferences.
