Engine and Performance: The Heart of a Beast
The 2018 Mercedes G63 AMG is powered by a 4.0-liter twin-turbocharged V8 engine, hand-assembled by a single AMG technician—a tradition that ensures precision and pride in every unit. This powerhouse delivers a staggering 577 horsepower and 627 pound-feet of torque, launching the nearly 5,500-pound SUV from 0 to 60 mph in just 5.2 seconds. That’s supercar territory for a vehicle that can also ford rivers and climb 100% gradients.
AMG Speedshift TCT 9-Speed Transmission
Paired with the engine is the AMG Speedshift TCT 9-speed automatic transmission, designed for rapid shifts and seamless power delivery. Whether you’re accelerating on the highway or crawling over boulders, the transmission adapts intelligently. It features multiple driving modes—Comfort, Sport, Sport+, and Individual—letting you tailor the response to your mood or terrain. In Sport+ mode, shifts happen in milliseconds, and the exhaust note becomes even more aggressive, turning heads and thrilling drivers alike.
Exhilarating Sound and Feel
One of the most thrilling aspects of the G63 AMG is its sound. The AMG Performance exhaust system delivers a deep, resonant rumble that builds into a roar under hard acceleration. It’s not just noise for show—it’s a visceral reminder of the engineering beneath the surface. The engine note is tuned to be both aggressive and refined, striking a balance between raw power and luxury. Even at idle, there’s a low growl that hints at the beast within.
Real-World Driving Experience
On the road, the G63 AMG feels surprisingly agile for its size. The steering is precise, and the adaptive suspension (standard on this model) keeps body roll in check during cornering. While it’s no sports car, it handles tighter than you’d expect from a boxy SUV. On the highway, it’s smooth and composed, eating up miles with ease. But where it truly shines is when you push it—whether on a winding mountain road or a straight drag strip. The acceleration is relentless, and the braking system (with large AMG-branded calipers) brings this ton-heavy vehicle to a stop with confidence.
Design and Exterior: Timeless Meets Modern

The 2018 G63 AMG’s design is instantly recognizable. It retains the G-Class’s iconic boxy shape, a silhouette that has remained largely unchanged since the 1970s. But Mercedes has modernized it with sleek LED headlights, a bold AMG-specific grille, and aggressive front and rear bumpers. The result is a vehicle that looks both rugged and refined.
Signature AMG Styling Cues
AMG models get unique design elements that set them apart from the standard G550. These include a blacked-out grille with vertical slats, 20-inch AMG alloy wheels (with optional 22-inch upgrades), and dual trapezoidal exhaust tips. The side skirts are more pronounced, and the rear spoiler adds a subtle sporty touch. Every detail is designed to emphasize performance and exclusivity.
Customization and Paint Options
One of the joys of owning a G63 AMG is the ability to personalize it. Mercedes offers a wide range of paint colors, from classic black and white to bold options like designo Diamond White or Night Black Magno. You can even opt for two-tone finishes or matte wraps. The G63 AMG also supports the designo program, which allows for bespoke interior and exterior finishes. Want gold trim? Custom badging? It’s all possible.
Practical Features with Style
Despite its aggressive look, the G63 AMG is surprisingly practical. The spare tire mounted on the rear door is both a design signature and a functional feature. The side-hinged tailgate makes loading easier, and the wide-opening doors provide easy access to the cabin. Roof rails come standard, and you can add a roof rack for extra cargo capacity. Even the door handles are mechanical—no electronic latches—ensuring reliability in extreme conditions.
Interior Luxury: A Sanctuary on Wheels
Step inside the 2018 G63 AMG, and you’re greeted by a cabin that rivals high-end sedans. The materials are top-tier: Nappa leather upholstery, real aluminum or wood trim, and soft-touch surfaces throughout. The seats are power-adjustable, heated, and ventilated, with optional massage functions. It’s a space designed for comfort and control.
Advanced Infotainment and Technology
The centerpiece of the dashboard is the COMAND infotainment system, displayed on a 12.3-inch screen. It supports Apple CarPlay, Android Auto, navigation, and a 15-speaker Burmester surround sound system. The interface is intuitive, with a touchpad controller and voice commands. For 2018, Mercedes also introduced the optional dual-screen setup, with a digital instrument cluster and central display, giving the cabin a futuristic feel.
Comfort and Convenience Features
Every seat in the G63 AMG is designed for long-distance comfort. The front seats offer multiple adjustments, including lumbar support and thigh extenders. Rear passengers get ample legroom and their own climate controls. Ambient lighting with 64 colors sets the mood, and the panoramic sunroof (optional) floods the cabin with natural light. Even the cup holders are heated and cooled—perfect for keeping drinks at the ideal temperature.
Storage and Practicality
Despite its luxury focus, the G63 AMG doesn’t skimp on practicality. There are plenty of storage compartments, including a deep center console and door pockets. The cargo area is spacious, with 34.4 cubic feet behind the rear seats and up to 74.3 cubic feet with the seats folded. The power-folding rear seats make loading large items a breeze. For a vehicle this size, it’s surprisingly user-friendly.
Off-Road Capability: Built to Conquer
While the G63 AMG is a luxury vehicle, it’s also a true off-roader. It retains the G-Class’s rugged DNA, with a body-on-frame construction, three locking differentials, and a low-range transfer case. This isn’t just a pretty face—it’s built to handle the toughest terrain.
Three Locking Differentials
The G63 AMG comes standard with front, center, and rear locking differentials. When engaged, they ensure power is distributed evenly to all wheels, even if one or two are off the ground. This is crucial for rock crawling or muddy trails. The system is manually controlled via buttons on the center console, giving the driver full command.
Adaptive Suspension and Ground Clearance
The adaptive suspension system adjusts damping in real time, providing a smooth ride on pavement and maximum articulation off-road. Ground clearance is an impressive 9.5 inches, and the approach, departure, and breakover angles are optimized for steep inclines. The G63 AMG can also ford water up to 27.6 inches deep—more than enough for most river crossings.
Off-Road Driving Modes
In addition to the standard driving modes, the G63 AMG includes off-road-specific settings. These adjust throttle response, transmission shift points, and traction control for sand, rock, or snow. The hill descent control system automatically manages speed on steep declines, letting the driver focus on steering. It’s a system that makes even novice off-roaders feel like pros.
Real-World Off-Road Example
Imagine tackling a rocky trail in Moab, Utah. The G63 AMG climbs over boulders with ease, its tires gripping the uneven surface while the suspension absorbs every bump. The locking differentials keep all four wheels turning, even when one is airborne. On the descent, hill descent control keeps the speed steady, and the powerful brakes provide confidence. It’s a vehicle that doesn’t just look tough—it performs when it counts.
Safety and Driver Assistance
The 2018 G63 AMG is equipped with a comprehensive suite of safety features. While it’s not as tech-heavy as newer models, it still offers advanced driver aids that enhance security and convenience.
Active Safety Systems
Standard features include adaptive cruise control, blind-spot monitoring, lane-keeping assist, and forward collision warning with automatic braking. The system can detect pedestrians and apply the brakes if a collision is imminent. Rear cross-traffic alert helps when backing out of parking spots, and a 360-degree camera system provides a bird’s-eye view of the vehicle.
Passive Safety and Build Quality
The G63 AMG’s body-on-frame construction is inherently strong, providing excellent protection in a crash. It earned a five-star overall safety rating from the NHTSA. The cabin is reinforced with high-strength steel, and the vehicle comes with eight airbags, including side curtains for all three rows. The rigid structure also contributes to the vehicle’s durability and off-road resilience.
Night Vision and Parking Assist
Optional features include Night Vision with pedestrian detection, which uses infrared cameras to spot hazards in low-light conditions. The parking assist system can parallel park the vehicle automatically, a helpful feature given the G63 AMG’s size. These technologies add peace of mind, especially in urban environments.
Ownership Experience and Value
Owning a 2018 Mercedes G63 AMG is about more than just driving—it’s a lifestyle statement. It’s a vehicle that attracts attention, sparks conversations, and delivers an unforgettable experience every time you get behind the wheel.
Maintenance and Reliability
The G63 AMG is built to last, but it requires regular maintenance to keep it running at peak performance. Scheduled service intervals are every 10,000 miles or 12 months, and it’s recommended to use only Mercedes-approved parts and fluids. Common issues include minor electrical glitches or wear on suspension components, but overall, the 2018 model is considered reliable for its class.
Fuel Economy and Running Costs
Let’s be honest—fuel economy isn’t the G63 AMG’s strong suit. It averages around 13 mpg in the city and 16 mpg on the highway. With a 26.4-gallon tank, you’ll be filling up often, especially if you drive aggressively. However, for owners of this vehicle, fuel cost is often a secondary concern. The experience and prestige outweigh the expense.
Resale Value and Collector Appeal
The G63 AMG holds its value remarkably well. Due to limited production numbers and high demand, used models often retain 60–70% of their original value after three years. Enthusiasts and collectors prize the G-Class for its heritage, and the AMG version is especially sought after. Well-maintained examples with low mileage can even appreciate over time.
Community and Culture
Owning a G63 AMG connects you to a passionate community of fans. From G-Wagen clubs to AMG-specific events, there are plenty of opportunities to meet fellow owners and share experiences. Online forums and social media groups are filled with tips, mods, and stories. It’s more than a car—it’s a tribe.
Conclusion: The Ultimate Luxury Off-Roader
The 2018 Mercedes G63 AMG is a rare breed: a vehicle that combines brute strength, off-road mastery, and unparalleled luxury. It’s not for everyone—but for those who appreciate its unique blend of power, heritage, and style, it’s irresistible. Whether you’re navigating city streets or exploring remote trails, the G63 AMG does it with confidence and flair.
It’s a vehicle that refuses to compromise. You get the thunder of a V8, the comfort of a five-star hotel, and the capability of a military-grade machine—all wrapped in a design that’s stood the test of time. In a world of increasingly soft SUVs, the G63 AMG remains a true icon.
