Overview
The Mercedes-Benz G63 AMG 6×6 stands as a testament to automotive engineering prowess, a limited-production marvel manufactured from 2013 to early 2015. This extraordinary off-road vehicle combines a 6-wheel drive system with portal axles and massive 37-inch tires, delivering unparalleled capability across the most challenging terrains. Beneath its rugged exterior, a potent V8 twin-turbo engine and a lavish leather-clad interior place it firmly within the upper echelons of the luxury automotive market. The Mercedes-Benz G63 AMG 6×6 is not just an off-roader; it’s a statement of extreme capability and opulent design.
Base Vehicle and Powertrain
Built upon the robust foundation of the military-grade G 6×6 frame, the civilian Mercedes-Benz G63 AMG 6×6 harnesses the formidable AMG 5.5-liter V8 twin-turbo engine. This powerplant delivers a staggering 544 horsepower (400 kW) and 760 Nm of torque. A responsive 7-speed automatic gearbox, coupled with a 2-speed transfer case, efficiently channels this power to the advanced portal axles. Within the secondary axle housing resides another transfer case, intelligently distributing power with a 60/40 split favoring the rear axles, optimizing traction and control. Drivers can tailor the driving experience through the 7-speed gearbox’s selectable modes: “Controlled Efficiency” (C), Sport (S), and Manual (M). Enhanced communication between the engine and gearbox electronics allows for rapid and seamless gear changes, adapting to diverse driving demands.
Despite carrying the prestigious AMG badge, AMG’s direct involvement in the G63 AMG 6×6’s production was primarily focused on the high-performance V8 engine and the exquisitely crafted leather interior. Mercedes-Benz collaborated with specialized partners like Magna, LeTech, and Oberaigner, leveraging their expertise. Magna Steyr, renowned for vehicle assembly, manufactured the G-Class vehicles in Graz, Austria. LeTech (Lennartz-technik) engineered and produced the innovative portal axles and the central tire inflation system, crucial for the vehicle’s off-road prowess. Oberaigner designed the secondary transfer case, enabling the sophisticated 6-wheel drive system of the G 6×6.
In terms of fuel efficiency, Mercedes-Benz officially quoted combined fuel consumption figures ranging from 19.6 to 11.2 liters per 100 kilometers, with combined CO₂ emissions between 459 and 295 g/km. The top speed is electronically limited to 160 km/h, prioritizing control and safety in this high-performance off-road machine.
Suspension and Handling
The Mercedes-Benz G63 AMG 6×6 employs coil springs on all six wheels, ensuring a robust and adaptable suspension system. Uniquely, the rear axles lack a load-sharing mechanism, a design choice compensated for by Mercedes-Benz’s implementation of differing spring ratings on the second and third axles. This configuration strategically results in a 60/40 weight distribution across the two rear axles, contributing to a reduced turning circle and enhanced maneuverability for such a large vehicle. The front two axles are equipped with uprated coil springs derived from the armored 4×4 G-Wagon, underscoring the vehicle’s durability and load-bearing capacity. High-performance Öhlins gas bypass shocks complete the suspension setup, providing exceptional damping and control across varied terrains.
Central Tire Inflation System: Mastering Any Terrain
A cornerstone of the Mercedes-Benz G63 AMG 6×6’s exceptional off-road capabilities is the integration of specialized 18-inch beadlock wheels and a central tire inflation system. This advanced system allows drivers to drastically reduce tire pressure for optimal performance on soft surfaces like sand. At extremely low pressures, the ground pressure exerted by the massive tires is comparable to the footprint of an average human, providing remarkable flotation and traction. The system enables rapid adjustment of tire pressure, increasing from a mere 0.5 bar (ideal for soft sand) to 1.8 bar (for on-road driving) in under 20 seconds. This rapid inflation and deflation are facilitated by the vehicle’s onboard compressor and four substantial 20-liter air tanks, discreetly housed within the rear wheel arches. Operation of the central tire inflation system is conveniently managed via controls located in the overhead console.
Limited Sales and Exclusivity
Production of the Mercedes-Benz G63 AMG 6×6 was strictly limited, with just over 100 units sold worldwide, each commanding a price of approximately €450,000. All factory-produced models were left-hand drive configurations, further enhancing their exclusivity. While officially only left-hand drive models were produced, some reports suggest that around 15 right-hand drive versions were commissioned in Malaysia through the tuner Brabus. These are believed to be conversions from left-hand drive models, indicating the lengths to which enthusiasts went to own this rare machine in right-hand drive markets.
Tuning and Customization
Despite its already stratospheric price tag and performance, the Mercedes-Benz G63 AMG 6×6 became a favored canvas for high-end automotive tuners. Renowned names like Brabus (offering a 700 HP upgrade), Mansory (pushing output to 829-hp and 1000 Nm of torque), Carlsson (tuning to 630 HP and 900 Nm), and Dartz (reaching a staggering 1019 hp and 1000 Nm) all offered bespoke modification packages. Leveraging the G63 AMG’s standard AMG V8 engine and 7-speed gearbox, tuners typically installed their existing engine tuning kits designed for this AMG powerplant. Performance enhancements were often complemented by lavish interior customizations, featuring unique color schemes, extended leather upholstery, and bespoke trim. Exterior modifications ranged from subtle styling tweaks to more dramatic body kit additions. Dartz notably offered stretched wheelbase and armored versions of the G 63 AMG 6×6, catering to ultra-high-net-worth individuals seeking unparalleled levels of customization and security.
It is worth noting that the Mercedes-Benz G63 AMG 6×6 was never officially sold in Europe, the United States, or Australia, making its presence in these markets even more exceptional, typically through private imports.
