2019 Mercedes-Benz GLS (X167) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz GLS (X167) ranges from 2385 kg to 2785 kg (5,260 to 6,141 pounds), depending on the trim and equipment levels. The maximum allowable weight of the vehicle, which includes passengers, cargo, and the vehicle's own mass, varies between 3230 kg and 3395 kg (7,120 to 7,485 pounds). This robust weight capacity ensures that the GLS can safely handle heavy loads while still maintaining its refined ride quality. Its construction balances luxury features with the durability needed for a large SUV.

The luggage capacity in the Mercedes-Benz GLS (X167) ranges between 355 liters and 520 liters (12.5 to 18.3 cubic feet) with the rear seats upright, offering ample space for everyday needs such as groceries or luggage for short trips. When the rear seats are folded down, the cargo space dramatically increases to approximately 2400 liters (84.7 cubic feet). This flexibility allows the GLS to accommodate bulky items, making it a versatile vehicle for both passenger comfort and utility.

The Mercedes-Benz GLS (X167) has a ride height, or ground clearance, of about 200 mm (7.87 inches). This relatively high ground clearance enhances the vehicle's ability to drive over rough terrain, shallow water crossings, or uneven road surfaces without damaging the undercarriage. It also contributes to an elevated driving position, improving driver visibility. The combination of ground clearance and adaptive suspension technology makes the GLS suitable for light off-road use while remaining comfortable on paved roads.

Fitting the Mercedes-Benz GLS (X167) into a standard residential garage can be challenging but is generally manageable depending on the garage size. The SUV’s length is around 5205 mm to 5207 mm (about 17 feet 1 inch), and its width with mirrors folded ranges up to 2030 mm (about 6 feet 8 inches), while some residential garages have dimensions around 6 meters (19.7 feet) deep and 2.4 meters (7.9 feet) wide. The height of 1823 mm to 1838 mm (approximately 6 feet) is typically not an issue in standard garages. However, you must consider opened mirror widths up to 2157 mm (7.1 feet), which often require folding mirrors to fit comfortably. Thus, owners should verify their garage dimensions closely and use caution when parking.

Compared to its predecessor, the X166 generation GLS, the X167 is generally larger and more refined. The X167 increased in length offering about 5205 mm (204.9 inches), which is slightly longer than the previous generation that measured approximately 5169 mm (203.5 inches). The width was also expanded with wider mirror spans, improving passenger comfort and interior space. Height increased marginally as well. The weight rose due to added luxury features and technology enhancements, leading to a slightly heavier vehicle with improved equipment and safety systems. Overall, the X167 is bigger and taller, delivering enhanced presence and refinement compared to the older generation.

Within the full-size luxury SUV segment, the Mercedes-Benz GLS (X167) ranks among the larger contenders. For instance, it is close in length to the BMW X7 (approximately 5167 mm / 203.5 inches) and the Audi Q7 L (about 5052 mm / 198.8 inches), offering competitive interior space and cargo capacity. In width and height, the GLS is similarly spacious or slightly larger, particularly accounting for its variable mirror widths. The GLS combines generous dimensions with luxury-appointed interiors and advanced technology, positioning it effectively against rivals in terms of passenger comfort and usability. Buyers seeking a large, prestigious SUV will find the GLS offers notable size advantages and premium features in comparison.

The Mercedes-Benz GLS (X167) offers a broad range of rim sizes from 19 inches up to 23 inches. Rim widths vary from 8.5J to 11.5J, incorporating sizes such as 19, 20, 21, 22, and 23 inches, often paired with high-performance tires like 275/45 R21, 315/40 R21, 325/35 R23, and others. Larger rims can enhance handling and provide a sportier appearance but may slightly reduce ride comfort due to lower-profile tires. Smaller wheels typically improve ride cushioning and off-road capability. This variety allows buyers to tailor the GLS’s performance and aesthetics according to preferences, balancing comfort, style, and driving dynamics.

The Mercedes-Benz GLS (X167) is designed as a full-size luxury SUV that comfortably seats seven passengers in a three-row configuration. The interior is spacious, providing ample legroom and headroom for front and rear occupants, supported by its lengthy 5205 mm (204.9 inches) body. High-quality materials and advanced features ensure passenger comfort throughout all seating rows. The vehicle's width also contributes significantly to the roomy cabin environment. Standard and optional luxury amenities, combined with the generous dimensions, make the GLS an excellent choice for families or groups requiring space without compromising luxury.

With a ground clearance of approximately 200 mm (7.87 inches), the Mercedes-Benz GLS (X167) is well-equipped to handle mild off-road terrain such as dirt roads, gravel, or uneven city surfaces. Its sizable length (around 5.2 meters / 17 feet) and width also contribute to a commanding presence in urban environments. While these dimensions offer a spacious interior and comfortable ride, navigating tight city streets or parking in congested areas can be more challenging. However, features like parking assist systems and foldable mirrors help mitigate these concerns. The GLS balances capability with luxury, making it versatile for both light off-road adventures and everyday city driving.
