Powertrain & Engine Architecture

The G 500 V8 4×4² is powered by the M176.980 4.0-liter twin-turbocharged V8 engine. This engine, a cornerstone of Mercedes-AMG’s performance lineup, delivers 422 horsepower at 5250-5500 rpm and 610 Nm (449.91 lb-ft) of torque between 2250 and 4750 rpm. The engine utilizes direct fuel injection and a sophisticated engine management system to optimize performance and efficiency. The twin-turbocharger setup provides immediate throttle response and a broad torque curve. The engine is longitudinally mounted in the front of the vehicle. Paired with the engine is the 7G-TRONIC seven-speed automatic transmission, known for its smooth shifting and responsiveness. This transmission is specifically tuned to handle the engine’s substantial torque output and provide appropriate gear ratios for both on-road cruising and challenging off-road conditions. The 4×4² features a full-time all-wheel-drive system with three locking differentials, enhancing its off-road prowess.

Driving Characteristics

The G 500 V8 4×4² offers a unique driving experience. While the V8 provides ample power for swift acceleration (0-60 mph in approximately 7.1 seconds), the vehicle’s substantial weight (2946 kg / 6494.82 lbs) and high center of gravity are noticeable. The 7G-TRONIC transmission provides smooth and quick gear changes, but isn’t geared for maximum fuel efficiency. The 4×4²’s defining characteristic is its exceptional off-road capability. The portal axles, which house the wheel hubs and allow for significant suspension articulation, provide an astonishing 438mm (17.24 inches) of ground clearance. This, combined with the locking differentials, allows the G 500 to traverse extremely challenging terrain. Compared to the standard G 500, the 4×4² offers a more composed ride on rough surfaces, but the increased height and weight can result in more body roll during cornering on paved roads.

Equipment & Trim Levels

The G 500 V8 4×4² came standard with a high level of equipment, reflecting its premium positioning. Standard features included leather upholstery, heated and ventilated front seats, a premium sound system, navigation, and a host of driver-assistance systems. The interior featured unique trim elements specific to the 4×4² model. Optional extras included a sunroof, upgraded leather options, and various customization packages. The dashboard layout was typical of the W463 G-Class, with a functional and robust design.

Chassis & Braking

The G 500 V8 4×4² utilizes a robust ladder-frame chassis, a hallmark of the G-Class lineage. The suspension consists of rigid axles front and rear, providing exceptional durability and articulation. The braking system features ventilated discs on all four wheels, paired with an Anti-lock Braking System (ABS) for enhanced stopping power and control. Due to the vehicle’s weight, braking performance is adequate but not exceptional. The steering system employs a recirculating ball mechanism, providing a direct and tactile feel, although it lacks the precision of more modern steering technologies.

Market Reception & Comparison

The G 500 V8 4×4² was generally well-received by automotive critics, who praised its exceptional off-road capability, powerful engine, and luxurious interior. However, its high price tag and relatively poor fuel economy (13.8 l/100 km / 17 US mpg) were noted drawbacks. Compared to other G-Class variants, such as the G 350 d, the G 500 4×4² offered significantly more performance and off-road capability but at a substantial price premium. The G 500 4×4² targeted a niche market of buyers who prioritized extreme capability and exclusivity over fuel efficiency and affordability.

Legacy

The G 500 V8 4×4² remains a highly sought-after vehicle in the used car market. Its limited production run and unique capabilities have made it a collector’s item. The M176 engine, while powerful, requires regular maintenance to ensure reliability. The 7G-TRONIC transmission is generally reliable, but like any complex automatic transmission, it can be susceptible to issues if not properly maintained. The 4×4²’s robust chassis and suspension are known for their durability, but the vehicle’s age and potential for off-road abuse should be considered when evaluating a used example. The G 500 V8 4×4² cemented the G-Class’s reputation as a supremely capable and luxurious off-road vehicle, paving the way for future high-performance G-Class models.
