1990 Mercedes-Benz G-class (W463) Dimensions, Size & Specs

The curb weight of the Mercedes-Benz G-class (W463) ranges from 2060 kg to 2365 kg (approximately 4543 to 5215 pounds), depending on the configuration and trim level. The maximum permissible weight, which includes passengers, cargo, and additional load, is between 2620 kg and 2810 kg (5775 to 6197 pounds). This considerable weight underscores the vehicle's rugged construction with a sturdy body-on-frame design, heavy-duty suspension, and full-time four-wheel drive system. The solid build contributes to excellent off-road durability but may impact fuel efficiency and handling compared to lighter SUVs.

The ride height or ground clearance for the W463 G-class is approximately 210 mm (8.3 inches). This relatively high ground clearance is a crucial feature for off-road performance as it allows the vehicle to travel over uneven terrain, rocks, and obstacles without damaging the underbody. High ground clearance combined with its robust suspension and full-time four-wheel drive system makes the G-class adept at tackling challenging off-road conditions, including mud, sand, and steep inclines. This clearance also improves water fording capabilities, enhancing versatility in various environments.

The standard luggage capacity of the W463 G-class is 250 liters (about 8.8 cubic feet) when the rear seats are upright, which is modest but typical for an off-road vehicle focused on utility rather than cargo volume. When the rear seats are folded down, the cargo space expands significantly to 1580 liters (approximately 55.8 cubic feet), providing ample room for larger items or outdoor gear. This flexibility makes the vehicle more practical for long trips or transporting bulky items while maintaining the passenger comfort typical of a luxury SUV.

The Mercedes-Benz G-class (W463) has a roof load capacity of up to 150 kg (330 pounds). This means the roof can safely support a relatively heavy load such as luggage boxes, roof racks, or sporting equipment. This feature enhances the practicality of the vehicle for adventurous users who may need to carry additional gear like camping equipment, bicycles, or kayaks on the roof, complementing the already flexible interior cargo space.

The W463 G-class came with several rim options including 6 J x 16, 7.5 J x 16, 6 J x 16 (repeat likely for specific trims), 7.5 J x 18, reflecting a variety of wheel configurations suited for both on-road comfort and off-road ruggedness. Tire sizes supported on these rims include 205/80 R16, 255/65 R16, 205/80 R16, and 265/60 R18. These tire options offer a balance between grip, durability, and ride comfort on various terrains. Larger tires, particularly the 18-inch options, improve off-road traction and ground clearance, enhancing performance in demanding environments.

The Mercedes-Benz G-class (W463) generally fits into a standard home garage, but given its height and width, clearance and door width should be checked beforehand. Its width maxes out at 1760 mm (69.3 inches), and height can reach up to 1931 mm (76 inches). Most standard garages are around 2.4 to 2.7 meters (7.9 to 8.9 feet) wide and 2 to 2.3 meters (6.6 to 7.5 feet) high, so the vehicle’s width and height fit comfortably within typical garage dimensions. However, users with smaller garages or additional storage may need to measure carefully for ease of parking and door clearance. The compact length, between 4185 mm and 4230 mm (164.8 to 166.5 inches), helps in maneuverability within the space.

Compared to the W460 generation, the W463 G-class introduced in 1990 saw subtle changes in dimensions aimed at increasing comfort and luxury while retaining off-road capability. The W463 maintained a similar length range between 4185 mm and 4230 mm (164.8 to 166.5 inches), slightly refining width up to 1760 mm (69.3 inches) and height close to 1931 mm (76 inches), making it somewhat larger and more spacious than the W460. Additionally, the W463 saw improvements in curb weight, increasing due to added luxury appointments and safety features, rising to up to 2365 kg (5215 lbs). This generation also refined the interior and exterior styling, moving the model closer to a luxury SUV niche while keeping its rugged roots intact.

When compared to similar off-road vehicles from the 1990s, such as the Land Rover Defender or Jeep Cherokee, the Mercedes-Benz G-class (W463) is generally more compact in length but taller and heavier, reflecting its luxurious and robust build. For example, the Land Rover Defender of similar years is slightly longer but narrower, while the G-class's height (up to 1931 mm or 76 inches) offers more headroom and commanding road presence. Its heavier curb weight (2060-2365 kg or 4543-5215 lbs) compared to competitors underscores its sturdier frame and comprehensive luxury features. Overall, the W463 balances off-road capability with premium interior space and build quality, distinguishing it from more utilitarian rivals.

The Mercedes-Benz G-class (W463) offers 250 liters (8.8 cubic feet) of luggage space with rear seats up, which is modest but sufficient for typical daily use or short trips. When rear seats are folded down, the capacity expands to a generous 1580 liters (55.8 cubic feet), allowing transportation of larger gear or multiple suitcases. This versatility makes the vehicle practical for extended journeys, family outings, or outdoor recreational activities like camping. Combined with a substantial roof load capacity of 150 kg (330 lbs), the W463 can support extra equipment on top, which further enhances its utility as a capable and adaptable off-road and adventure vehicle.
