2013 Mercedes-Benz G-class 6x6 (W463) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz G-class 6x6 is 3775 kg (approximately 8320 lbs). This heavy mass is due to its six-wheel drive system, reinforced chassis, and additional axle. The added weight enhances traction and stability on rough terrain but also affects fuel consumption and maneuverability. Drivers should anticipate a powerful yet dense vehicle that excels in extreme off-road conditions but may require more effort to handle in urban or tight environments.

The G-class 6x6 offers an impressive ground clearance of 460 mm (18.1 inches), which is exceptional for an off-road vehicle. This high clearance allows the vehicle to navigate over large obstacles such as rocks, deep ruts, and uneven terrain without damaging the undercarriage. It significantly improves the vehicle's approach, departure, and breakover angles, making it one of the most capable off-road trucks in its class.

Given its width of 2110 mm (83.1 inches) and height of 2210 mm (87 inches), the Mercedes-Benz G-class 6x6 is larger than typical vehicles. Standard residential garages usually have door widths around 2400 mm (94.5 inches) and heights near 2100-2200 mm (82.6-86.6 inches). While the width may fit with limited clearance, the height of the 6x6 might be close or slightly exceed typical garage door heights, making it a tight fit in some cases. Owners may need to use specialized or commercial garages designed for larger vehicles.

Compared to the standard two-axle Mercedes G-class (W463), the 6x6 version is substantially longer and taller. The conventional W463 typically measures about 4630 mm (182.3 inches) in length, significantly shorter than the 6x6's 5875 mm (231.3 inches). The width is similar, around 1900-2000 mm (74.8-78.7 inches), making the 6x6 notably wider at 2110 mm (83.1 inches). The 6x6's extra axle adds length and weight, elevating it to a unique niche between trucks and SUVs, focusing on extreme off-road capability and payload.

Equipped with massive 37-inch tires (R37) mounted on appropriately sized rims, the Mercedes G-class 6x6 benefits from enhanced off-road traction, increased ground clearance, and improved obstacle climbing ability. These large tires help distribute the vehicle's weight better over rough surfaces and contribute to its aggressive stance. On-road, while providing a commanding presence and some comfort benefits from tire cushioning, the large tires may impact fuel efficiency, noise levels, and handling compared to smaller, standard tires.

Despite its imposing external size, the Mercedes G-class 6x6 retains the familiar luxury and comfort synonymous with the brand. The interior typically features premium materials, ample seating for up to five passengers, and advanced technology. However, the spaciousness is partially focused on accommodating specialized off-road equipment and robust mechanical components, so the passenger cabin may not be vastly larger than the standard G-class. The extra length is mainly utilized for the additional axle and cargo area in the pickup bed.

The Mercedes-Benz G-class 6x6 features an advanced six-wheel drive system that powers all six wheels concurrently, greatly enhancing traction on challenging surfaces like sand, mud, and snow. The additional axle provides superior load distribution and stability over rugged terrain. Coupled with high ground clearance and locking differentials, the 6x6 drivetrain enables this vehicle to conquer obstacles and terrains that are typically inaccessible to traditional four-wheel drive off-roaders.

During its production years (2013-2015), the Mercedes G-class 6x6 was unique in its class due to a combination of luxury, six-wheel-drive layout, and massive dimensions. Compared to other luxury off-road pickups like the Range Rover Sport or the Toyota Land Cruiser pickup variants, the 6x6 is significantly longer (5875 mm / 231.3 inches) and taller (2210 mm / 87 inches) with its 6x6 drivetrain and huge 37-inch tires. It outmatches typical competitors with superior off-road engineering and exclusive styling but also comes with a much higher curb weight and price.

Due to its considerable length (5875 mm / 231.3 inches), width (2110 mm / 83.1 inches), height (2210 mm / 87 inches), and heavy curb weight (3775 kg / 8320 lbs), the G-class 6x6 is not ideally suited for everyday urban driving or tight spaces. Its size affects maneuverability and parking convenience, while the weight can influence fuel consumption. However, for enthusiasts who require extreme off-road capabilities combined with luxury, this vehicle offers a unique, uncompromising experience. It is best considered a specialized vehicle rather than a daily commuter.
