2008 Mercedes-Benz G-class Long (W463, facelift 2008) Dimensions, Size & Specs

The curb weight of the W463 facelift 2008 G-Class Long ranges from 2305 kg to 2515 kg (approximately 5085 to 5547 pounds). The maximum permissible weight is rated at 3200 kg (7055 pounds). This weight range reflects the robust build quality of this off-road vehicle combined with luxury features, ensuring durability and substantial carrying capacity for both passengers and cargo.

This G-Class Long model offers a luggage capacity of 480 liters (16.95 cubic feet) with the rear seats in their upright position, which is sufficient for everyday use and moderate trips. When the rear seats are folded down, the cargo space expands significantly to 2250 liters (79.45 cubic feet), providing ample room for large items, camping gear, or bulky equipment, ideal for extended road trips or off-road excursions.

The ride height or ground clearance of this model is 205 mm (8.07 inches). This generous ground clearance is a critical factor that allows the G-Class Long to tackle rough terrains, deep ruts, and obstacles without damaging the undercarriage. It enhances the off-road performance by enabling the vehicle to clear uneven surfaces and steep inclines, making it well-suited for challenging outdoor conditions.

Fitting the G-Class Long into a standard residential garage depends on the garage dimensions. With an overall length of 4662 mm (183.5 inches) and a width of 2007 mm (78.9 inches) including mirrors, plus a height of 1931 mm (76 inches), this SUV is somewhat large compared to average sedans. Standard garages, often around 2.4 to 2.7 meters in width and 5 to 6 meters in length, can typically accommodate it, but tight fits may occur especially with mirror clearance. Drivers are advised to measure their garage space carefully before purchasing.

The G-Class Long comes with a variety of rim sizes including 7.5J x 18, 7.5J x 16, and 9.5J x 19, paired with tire sizes such as 265/60 R18, 265/70 R16, and 275/55 R19. Larger rims with wider tires, like the 9.5J x 19 with 275/55 R19 tires, enhance road grip and handling on paved roads and moderate off-road terrains. Smaller rims and higher profile tires (e.g., 265/70 R16) provide more sidewall cushioning, which is beneficial for rough terrain and absorbing shocks to improve ride comfort during off-road driving.

Compared to its predecessor, the facelifted W463 G-Class Long (2008-2012) retained much of the classic boxy design and dimensions typical of the G-Class but incorporated modern updates. The facelift improved comfort and technology without drastically altering its size, maintaining a length of 4662 mm, a width around 1760 mm, and a height near 1931 mm. Functionally, the newer generation featured refined interiors, enhanced safety features, and upgraded suspension components, offering improved ride quality and off-road capability over its predecessor, while maintaining the rugged character.

When compared to similar luxury off-road SUVs like the Range Rover or the Lexus LX, the Mercedes-Benz G-Class Long is often considered more compact in width (1760 mm without mirrors) but taller (1931 mm), giving it a distinctive upright stance. While its length at 4662 mm is competitive, its boxy design maximizes interior space and cargo utility. Its off-road capabilities are generally superior due to its robust ladder-frame chassis and locking differentials, whereas some competitors lean more towards road comfort. The G-Class Long balances luxury and serious off-road prowess uniquely, making it a favorite among enthusiasts.

The G-Class Long has a roof load capacity of 200 kg (approximately 441 pounds). This makes it suitable for carrying additional luggage, roof racks, or rooftop cargo carriers, provided the load does not exceed this limit. When outfitting the vehicle with roof accessories, it is important to consider the weight distribution and aerodynamic impacts; however, 200 kg is a generous allowance for most typical roof cargo needs such as bike racks, storage boxes, or light rooftop tents.

The dimensional and weight characteristics of the G-Class Long—such as its 4662 mm length, 2305-2515 kg curb weight, and 1931 mm height—have a direct impact on fuel efficiency and handling dynamics. Its relatively large size and heavy curb weight result in higher fuel consumption compared to smaller SUVs. The tall and boxy design increases aerodynamic drag, affecting highway fuel economy. However, these dimensions provide excellent interior space and allow for superior off-road capability. Handling is robust but can feel less agile on tight city roads due to the vehicle's size and weight, favoring stability and durability over nimbleness.
