2018 Mercedes-Benz G-class Long (W463, facelift 2018) Dimensions, Size & Specs

The width of the Mercedes-Benz G-class Long (W463, facelift 2018) varies between 1892 mm and 1984 mm (approximately 74.4 to 78.1 inches) when the mirrors are folded. When the mirrors are opened, the width extends to 2187 mm, which equals about 86.1 inches (7.17 feet). This considerable width including mirrors is important for awareness during off-road driving and urban parking situations, where the driver must consider the vehicle’s widest point to avoid obstacles.

The height of the Mercedes-Benz G-class Long facelift (2018 to 2024) is between 1966 mm and 1969 mm, which is approximately 77.4 to 77.5 inches or around 6 feet 5.4 inches to 6 feet 5.5 inches. This tall stature helps provide excellent ground clearance and a commanding driving position, which is a hallmark of the G-class design and enhances its off-road capabilities as well as visibility on-road.

The curb weight of the G-class Long facelift version ranges from 2354 kg to 2651 kg (5193 lbs to 5846 lbs), depending on the configuration and equipment fitted to the vehicle. The maximum permissible weight, which includes passengers, cargo, and additional load, spans from 3150 kg to 3200 kg (6944 lbs to 7055 lbs). The substantial weight contributes to the vehicle's sturdy and robust feel, enhancing safety and road grip especially on rough terrain.

The standard luggage capacity in the Mercedes-Benz G-class Long ranges from 667 liters to 1079 liters (approximately 23.6 to 38.1 cubic feet). When the rear seats are folded down, the capacity significantly expands to between 1941 liters and 1943 liters (around 68.5 to 68.6 cubic feet). This versatile cargo space makes the G-class Long practical for both everyday use and off-road adventures, providing ample room for gear, luggage, and equipment.

Fitting the Mercedes-Benz G-class Long (W463 facelift 2018) into a standard residential garage can be challenging given its dimensions. The vehicle's length varies between 4818 mm and 4881 mm (15.8 to 16 feet), and its width with mirrors opened is 2187 mm (7.17 feet). Most standard garages have a width of about 2400 mm (7.87 feet) and a length of roughly 5400 mm (17.7 feet). While the length is generally acceptable, the width with mirrors extended requires careful attention when entering and exiting the garage to avoid scratching the vehicle or the garage walls. The height of approximately 1966 mm to 1969 mm (6 feet 5.4 to 6 feet 5.5 inches) is typically not an issue for garage clearance. Owners often fold the mirrors to better accommodate the vehicle inside tighter garage spaces.

Compared to its predecessor, the 2018 facelift version of the Mercedes-Benz G-class Long (W463) maintains the classic boxy shape but introduces subtle dimensional enhancements and technological upgrades. Lengthwise, the facelifted model spans 4818 mm to 4881 mm (189.6 to 192.1 inches), slightly increasing over previous versions which were closer to 4700 mm to 4750 mm. The width saw a marginal increase too, from around 1880 mm to nearly 1984 mm (74 to 78.1 inches). Height remained fairly consistent around 1960 mm (6 feet 5 inches). Weight saw a small increase due to added safety and luxury features, with curb weight moving from approximately 2300 kg to upwards of 2650 kg (5070 to 5846 lbs). These changes result in a more luxurious, spacious, and safer vehicle while preserving the iconic off-road capabilities and design heritage of the G-class.

The Mercedes-Benz G-class Long facelift 2018 offers a ride height and ground clearance of approximately 241 mm (9.49 inches). This substantial ground clearance is pivotal for off-road performance, allowing the vehicle to traverse uneven terrain, rocks, deep ruts, and obstacles without damaging the undercarriage. It enhances the G-class's ability to tackle steep inclines, water fording, and rough trails, making it one of the elite off-road vehicles in its class. Combined with advanced all-wheel-drive systems and differential locks, the height ensures the G-class Long remains highly capable in challenging off-road conditions.

The Mercedes-Benz G-class Long facelift offers a variety of rim sizes including 8.5J x 19, 7.5J x 18, 8.5J x 20, 9.5J x 20, 10J x 21, 10J x 22, and 8J x 18 inches. Compatible tire sizes include 275/55 R19, 265/60 R18, 275/50 R20, 285/45 R21, and 295/40 R22. Larger rims with wider tires enhance road gripping ability, improve stability during high-speed cornering, and aesthetically contribute to a more aggressive look. Smaller rims and higher profile tires are preferred for better off-road cushioning and durability. This wide range allows owners to prioritize between off-road capability and on-road performance depending on personal preference and intended use.

In comparison to similar luxury off-road SUVs such as the Land Rover Range Rover, Toyota Land Cruiser, and Lexus LX, the Mercedes-Benz G-class Long facelift 2018 stands out with its distinctive tall and boxy design and impressive ground clearance of 241 mm (9.49 inches). Dimensionally, it is similar in length and width to these competitors, with around 4.8 to 4.9 meters in length and a width of nearly 2 meters (78+ inches). The G-class offers superior off-road features such as three fully locking differentials and a low-range transfer case, which some competitors may lack. It tends to be heavier—between 2354 and 2651 kg (5193 to 5846 lbs)—which contributes to a solid, durable feel but may affect fuel efficiency. Overall, the G-class Long is tailored for those who want uncompromising off-road prowess where size, presence, and legendary capabilities are essential.
