The 2024 Mercedes-Benz AMG G 63 Long represents the latest evolution of a vehicle steeped in history. Originally designed as a military vehicle in the 1970s, the G-Class transitioned to a civilian market icon, renowned for its robust construction and exceptional off-road prowess. The W465 generation, introduced in 2018, brought a significant modernization of the G-Class, incorporating advanced technology and enhanced comfort without sacrificing its core capabilities. The AMG G 63 Long variant, with its powerful V8 engine and extended wheelbase, caters to a discerning clientele seeking a unique blend of luxury, performance, and off-road capability. It sits at the very top of the G-Class lineup, commanding a substantial premium over other trims.
Powertrain & Engine Architecture
At the heart of the AMG G 63 Long lies the M 177 4.0-liter V8 engine, a masterpiece of engineering. This engine utilizes direct injection and is equipped with two twin-scroll turbochargers and an intercooler, producing 585 horsepower at 6000 rpm and a staggering 850 Nm (626.93 lb-ft) of torque between 2500 and 3500 rpm. The engine incorporates a mild-hybrid system, utilizing a 48V lithium-ion battery and an integrated starter-generator to provide power assistance and enable features like the Start/Stop system. The engine’s architecture is longitudinal, and it’s paired with the AMG SPEEDSHIFT TCT 9G automatic transmission. This transmission is a nine-speed torque-converter automatic, specifically tuned for rapid and precise gear changes. The transmission’s programming prioritizes performance, offering quick downshifts and responsive acceleration. The engine also features cylinder deactivation, shutting down cylinders under light load to improve fuel efficiency.
Driving Characteristics
The AMG G 63 Long delivers a driving experience that is both exhilarating and surprisingly refined. Despite its considerable weight (2565 kg / 5654.86 lbs), the engine’s immense torque provides effortless acceleration. The 0-60 mph sprint is dispatched in just 4.2 seconds, and the vehicle feels remarkably composed even at high speeds. The 9G transmission contributes to a smooth and seamless driving experience, with well-chosen gear ratios that keep the engine in its optimal power band. While the G-Class is not known for its nimble handling, the AMG-tuned suspension and steering provide a reasonable level of control and responsiveness. Off-road, the G 63 Long truly shines. Its robust construction, all-wheel-drive system, and ample ground clearance allow it to tackle challenging terrain with ease. The three locking differentials (front, center, and rear) provide maximum traction in even the most demanding conditions.
Equipment & Trim Levels
The AMG G 63 Long comes standard with a comprehensive array of luxury features. The interior is lavishly appointed with premium leather upholstery, heated and ventilated front seats, and a panoramic sunroof. Standard technology includes a 12.3-inch digital instrument cluster, a 12.3-inch touchscreen infotainment system with Mercedes-Benz’s MBUX interface, and a Burmester surround sound system. Optional extras include a variety of interior trim options, active suspension, and advanced driver-assistance systems. The extended wheelbase provides significantly more rear legroom compared to the standard G-Class, enhancing comfort for rear passengers.
Chassis & Braking
The G 63 Long utilizes a robust ladder-frame chassis, a hallmark of the G-Class’s design. The suspension consists of a double-wishbone setup at the front and a rigid axle suspension at the rear, both with coil springs and transverse stabilizers. The braking system features ventilated discs on all four wheels, providing ample stopping power. The AMG G 63 Long is equipped with ABS (Anti-lock braking system) and other advanced safety features.
Market Reception & Comparison
The AMG G 63 Long has been widely praised by automotive critics for its exceptional performance, luxurious interior, and unmatched off-road capability. However, its high price tag and relatively poor fuel economy (14.7-15.7 l/100 km) have been noted as drawbacks. Compared to other high-performance SUVs, the G 63 Long offers a unique combination of luxury and off-road prowess that few competitors can match. While models like the Range Rover offer similar levels of luxury, they lack the G-Class’s legendary off-road heritage. The G 63 Long’s reliability has been generally good, although maintenance costs can be high due to the complexity of the engine and drivetrain.
Legacy
The Mercedes-Benz AMG G 63 Long is poised to become a highly sought-after collectible in the future. Its combination of iconic design, powerful engine, and luxurious features makes it a truly special vehicle. The M 177 engine, while complex, is generally considered to be a robust and reliable unit when properly maintained. As with all G-Class models, the AMG G 63 Long is expected to hold its value well over time, making it a sound investment for enthusiasts and collectors alike. Its enduring appeal lies in its ability to seamlessly blend luxury, performance, and off-road capability, a combination that remains unmatched in the automotive world.
