2018 Buick GL6 Dimensions, Size & Specs

The curb weight of the Buick GL6 2018 is approximately 1465 kilograms (3230 pounds). This moderate weight contributes to its overall stability without heavily sacrificing fuel economy. A balanced curb weight enhances the vehicle's handling characteristics, offering responsive steering and a comfortable ride. The weight is supported by suspension tuned for minivan comfort, delivering a smooth driving experience while maintaining efficiency in daily commuting and longer trips.

Yes, the Buick GL6 2018 fits comfortably into most standard residential garages. With a length of 4692 mm (184.7 inches) and width of 1794 mm (70.6 inches), it is smaller than many full-size minivans and SUVs, which makes parking more convenient. A standard garage door is typically around 2.4 to 2.7 meters (94 to 106 inches) wide and about 2 meters (79 inches) high, so the GL6’s dimensions are well within those limits, making it a practical choice for families looking for both space and garage compatibility.

The Buick GL6 introduced in 2018 does not have a direct predecessor under the same name, as it was designed as a compact MPV/minivan targeted mainly at the Chinese market where it debuted. Compared to other Buick models that preceded it, the GL6 is more compact and lightweight, focusing on urban practicality and family use. It is smaller in length and height compared to traditional full-size Buick minivans, offering easier maneuverability while maintaining sufficient cabin space through its clever design.

The Buick GL6 2018 generation comes with 16-inch or 17-inch rim options. Tire sizes available are 205/60 R16 and 225/50 R17. The 16-inch tires typically offer a softer ride due to taller sidewalls, which absorb bumps better, making for a more comfortable family vehicle experience. Meanwhile, the 17-inch tires provide a firmer grip and enhanced handling characteristics but a slightly stiffer ride. This variety allows buyers to select the preferred balance between comfort and sportiness.

The Buick GL6 is designed primarily as a family-friendly minivan with seating for up to six or seven passengers, depending on the trim and seating configuration. Its modest exterior dimensions belie a surprisingly spacious interior, thanks to efficient use of cabin space and a boxy profile maximizing headroom and legroom. The GL6's flexible seating arrangements, including fold-flat or removable seats, facilitate various cargo and passenger needs, making it an adaptable vehicle for families requiring both passenger comfort and storage capabilities.

The Buick GL6 2018 fits comfortably within the compact minivan segment, making it slightly smaller in length and width compared to larger MPVs like the Toyota Sienna or Honda Odyssey. Its length of 4692 mm (184.7 inches) positions it near competitors like the Volkswagen Touran or Ford C-Max in terms of compact MPV size. With a width of 1794 mm (70.6 inches), it’s well-suited for densely populated urban areas, offering easier parking and maneuverability than some bulkier rivals, while still providing ample interior versatility.

While the exact ground clearance for the Buick GL6 2018 is not officially specified, it is designed as a city- and family-oriented minivan, generally offering moderate ground clearance around 145 to 160 mm (5.7 to 6.3 inches). This is sufficient for typical urban roads, mild rough patches, and uneven surfaces but is not optimized for off-road conditions. The clearance balances a low center of gravity for improved stability and handling with the ability to negotiate speed bumps, potholes, and sloped driveways comfortably.

The Buick GL6 2018 offers versatile cargo space typical of compact minivans. While exact trunk volume figures vary based on seat configuration, with all seats in use, there is ample room for daily groceries and luggage. Folding or removing rear seats significantly increases the cargo area, providing the capability to transport larger items, making it a highly practical choice for families and individuals needing flexible storage options. This adaptability places it in line with other vehicles in its segment for cargo versatility.

The Buick GL6 comes with two rim size options: 16-inch and 17-inch. The 16-inch rims typically provide a more comfortable ride by allowing for tires with taller sidewalls, which can absorb road imperfections better. They are ideal for drivers prioritizing comfort over sporty performance. The 17-inch rims offer a sleeker aesthetic, contributing to a more stylish appearance, and typically enhance cornering response and road grip due to shorter tire sidewalls. However, they may result in a slightly firmer ride, reflecting a trade-off between style and comfort.
