2018 Buick Regal VI GS Dimensions, Size & Specs

The curb weight of the Buick Regal VI GS is 1937 kg (4,271 lbs). This moderate weight for a midsize coupe provides a stable and planted driving experience. It aids in smooth handling dynamics while maintaining enough heft to offer a comfortable and stable ride with reduced impact from road imperfections or wind resistance.

The Buick Regal VI GS has a generous luggage capacity of 892 liters (31.5 cubic feet) with all seats up, which is excellent for a coupe. Folding the rear seats down expands this capacity significantly to 1719 liters (60.7 cubic feet), allowing for much larger cargo loads, making it quite practical for weekend trips or hauling larger items despite its sporty coupe design.

Yes, the Buick Regal VI GS fits comfortably into a standard garage. With a width of 1862 mm (73.3 inches) and height of 1455 mm (57.3 inches), it is well within the typical garage door opening width and clearance height. The length of 4900 mm (192.9 inches) is also manageable for most single-car residential garages, providing enough space for easy parking without requiring extra room.

Compared to its predecessor, the Regal VI GS is generally longer and wider, providing a more spacious interior and more aggressive road presence. Its increase in length and width contributes to improved stability and cabin space. The newer generation also tends to be slightly heavier due to added technology and refined build quality, which enhances comfort and safety but may impact fuel efficiency marginally.

The width of 1862 mm (73.3 inches) gives the Buick Regal VI GS solid road grip and stability, especially when cornering at higher speeds. A wider stance generally improves lateral stability and reduces body roll in curves, which complements the car’s sporty coupe design. However, this width may make urban parking slightly more challenging but well-balanced overall for its class.

The Buick Regal VI GS is equipped with 19-inch rims and performance tires sized 245/40 R19. Larger rims with lower profile tires enhance the car's handling characteristics by providing better grip, improved steering responsiveness, and a sportier look. However, this can slightly reduce ride comfort on rough surfaces due to stiffer sidewalls and less tire cushioning.

The height of 1455 mm (57.3 inches) contributes to the sleek and aerodynamic profile of the Regal VI GS, reducing drag and enhancing fuel efficiency at highway speeds. While the relatively low roofline improves aesthetics and performance, it means the cabin has a sportier, snugger feel, which may affect headroom marginally but suits the coupe style.

Compared to competitors like the Audi A5 Coupe or BMW 4 Series, the Buick Regal VI GS offers competitive dimensions with a length of 4900 mm (192.9 inches) and width of 1862 mm (73.3 inches) that provide ample interior and cargo space. Its larger luggage capacity (892 liters / 31.5 cu ft) especially with rear seats folded (1719 liters / 60.7 cu ft) stands out as highly practical for the segment, combining sporty appeal with everyday usability.

At 4900 mm (192.9 inches) long, the Buick Regal VI GS is on the larger side for a coupe, which may translate to a slightly larger turning radius compared to smaller cars. This length requires more attention when maneuvering in tight urban spaces or parallel parking but remains manageable with practice. The vehicle’s design balances this with good visibility and responsive steering to aid urban driving.
