What makes the 2021 model so special? For starters, it continues the legacy of the G-Class—a vehicle originally designed for military use in the 1970s—but transforms it into a street-legal super-SUV. Under the hood lies a hand-built AMG engine that roars to life with authority, while the interior feels more like a first-class airline cabin than a car.

Engine and Performance: Raw Power Meets Precision
At the heart of the 2021 Mercedes Benz G63 AMG is a masterpiece of engineering: the M176 4.0-liter twin-turbocharged V8 engine. This isn’t just any V8—it’s hand-assembled by a single technician at AMG’s Affalterbach facility, following the “One Man, One Engine” philosophy that ensures meticulous craftsmanship. The result? A staggering 577 horsepower and 627 pound-feet of torque, delivered with seamless urgency.
But power alone doesn’t define the G63 AMG. It’s how that power is managed that sets it apart. The engine is paired with a 9-speed AMG SPEEDSHIFT TCT automatic transmission, which shifts gears with lightning-fast precision. Whether you’re launching from a stoplight or overtaking on the highway, the response is immediate and exhilarating. The G63 rockets from 0 to 60 mph in just 4.4 seconds—faster than many sports cars—and tops out at an electronically limited 155 mph.
Driving Modes for Every Mood
One of the G63’s standout features is its dynamic driving modes. With the turn of a dial, you can switch between Comfort, Sport, Sport+, Individual, and off-road-specific settings like Sand, Rock, and Trail. Each mode adjusts the throttle response, transmission behavior, suspension stiffness, and even the exhaust note. In Sport+, the exhaust valves open fully, unleashing a deep, guttural growl that echoes through the cabin—perfect for making an impression at valet.
For daily driving, Comfort mode smooths out the ride, making the G63 surprisingly easy to live with. The adaptive air suspension absorbs bumps and potholes with ease, while the steering remains precise without being overly heavy. It’s this balance of performance and practicality that makes the G63 AMG so versatile.
All-Wheel Drive and Off-Road Prowess
Don’t let the chrome trim and leather seats fool you—the G63 AMG is still a true off-roader at its core. It comes standard with permanent all-wheel drive and a torque-splitting system that sends 40% of power to the front wheels and 60% to the rear under normal conditions. But when the going gets tough, the driver can manually lock the center, front, and rear differentials—a rare feature even among serious off-road vehicles.
Combined with a low-range transfer case, hill descent control, and a wading depth of up to 35 inches, the G63 can tackle sand dunes, rocky trails, and deep snow with confidence. We tested it on a muddy forest trail in upstate New York, and it climbed steep inclines and navigated ruts without breaking a sweat. The only downside? You’ll want to wash it immediately afterward—because nothing ruins a luxury SUV like mud splatter on the $2,000 optional AMG carbon fiber trim.
Interior Luxury: A Sanctuary on Wheels

Step inside the 2021 G63 AMG, and you’re greeted by a cabin that redefines SUV luxury. The first thing you’ll notice is the dual 12.3-inch widescreen display that spans the dashboard—one for the digital instrument cluster and one for the infotainment system. It’s sleek, modern, and incredibly intuitive, running the latest version of Mercedes’ MBUX (Mercedes-Benz User Experience) software.
But it’s not just about screens. The materials are where the G63 truly shines. Standard Nappa leather upholstery covers the seats, door panels, and center console, with optional diamond-quilted stitching for added elegance. The steering wheel is wrapped in perforated leather with aluminum paddle shifters, and the ambient lighting system offers 64 colors—yes, 64—so you can match your mood or match your outfit.
Seating and Comfort
The front seats are power-adjustable, heated, ventilated, and offer massage functions—perfect for long drives or chilly mornings. Rear passengers aren’t left out, either. The second-row seats are spacious, with ample legroom and headroom, and can also be equipped with heating and ventilation. For a vehicle with such a bold exterior, the interior feels surprisingly airy, thanks to the large windows and optional panoramic sunroof.
Storage is plentiful, with deep door pockets, a large center console, and even a cooled glovebox. There’s also a hidden compartment behind the rear seats—ideal for stashing valuables or emergency supplies.
Technology and Connectivity
The MBUX system is one of the most advanced in the industry. It supports voice control (“Hey Mercedes”), Apple CarPlay, Android Auto, and wireless charging. The navigation system uses augmented reality, overlaying directional arrows on a live camera feed to make turns easier to follow. There’s also a Burmester 3D surround sound system with 15 speakers—because why listen to music when you can feel it?
For families or frequent travelers, the G63 offers rear-seat entertainment screens, multiple USB-C ports, and even a built-in Wi-Fi hotspot. It’s the kind of tech that makes road trips feel like a vacation, not a chore.
Design and Exterior: Timeless Meets Aggressive
The 2021 Mercedes Benz G63 AMG doesn’t try to hide its roots. The boxy, angular design has remained largely unchanged since the 1970s, and that’s part of its charm. It’s instantly recognizable—whether you’re in downtown Miami or the Swiss Alps. But AMG has added its own flair with aggressive bodywork, wider fenders, and a bold front grille with vertical slats.
The standard 20-inch AMG alloy wheels can be upgraded to 22 inches, wrapped in high-performance tires that grip the road like glue. The LED headlights are adaptive, swiveling into corners to improve visibility, while the taillights feature a distinctive “night design” with dark-tinted lenses.
Customization and Personalization
One of the best things about the G63 AMG is how customizable it is. Mercedes offers a wide range of exterior colors—from classic black and white to bold options like designo Diamond White or Iridium Silver. You can also choose from matte finishes, carbon fiber accents, and even two-tone paint schemes.
Inside, the options are just as extensive. Choose from open-pore wood trim, carbon fiber, or piano black finishes. Add AMG performance seats with extra bolstering, a heads-up display, or even a refrigerated center console. With so many choices, no two G63 AMGs are exactly alike.
Aerodynamics and Practicality
Despite its boxy shape, Mercedes has worked to improve aerodynamics. The front bumper features active air flaps that close at high speeds to reduce drag, and the underbody is partially covered to smooth airflow. Still, the G63 isn’t exactly a fuel-sipper—expect around 13 mpg in the city and 16 mpg on the highway. But for a vehicle this powerful, that’s actually quite reasonable.
The rear hatch opens upward, revealing a cargo area of 38 cubic feet with the rear seats up—enough for groceries, luggage, or golf clubs. Fold the seats down, and you get a flat load floor with over 75 cubic feet of space. There’s also a power-operated tailgate with hands-free access—just wave your foot under the bumper to open it.
Safety and Driver Assistance: Peace of Mind in Motion
Luxury and performance are important, but safety is non-negotiable—especially in a vehicle this powerful. The 2021 G63 AMG comes loaded with advanced driver assistance systems that help prevent accidents and protect occupants.
Standard features include Active Brake Assist, which can detect pedestrians and vehicles and apply the brakes if a collision is imminent. Blind Spot Assist alerts you to vehicles in your blind spot with a warning light in the side mirror. Active Lane Keeping Assist gently steers you back into your lane if you drift unintentionally.
Adaptive Cruise Control and Parking Assistance
The G63 also includes Active Distance Assist DISTRONIC, a form of adaptive cruise control that maintains a set distance from the car ahead, even in stop-and-go traffic. It works seamlessly with Active Steering Assist, which helps keep the vehicle centered in its lane.
For parking, the G63 offers a 360-degree camera system with dynamic guidelines, making it easier to navigate tight spaces. There’s also Active Parking Assist, which can parallel or perpendicular park the vehicle with minimal driver input—just hold down a button and let the car do the work.
Structural Integrity and Crash Protection
The G-Class is built on a robust ladder frame, originally designed for military durability. While not as rigid as a unibody SUV, it’s incredibly tough and capable of withstanding extreme conditions. In the event of a crash, the cabin is reinforced with high-strength steel, and the vehicle comes with nine airbags, including side-impact and knee airbags for the front passengers.
While the G63 hasn’t been tested by the IIHS or NHTSA in 2021, earlier models received high marks for structural integrity and safety features. Mercedes’ reputation for safety engineering gives buyers confidence that they’re protected, even at high speeds.
Ownership Experience: More Than Just a Car
Owning a 2021 Mercedes Benz G63 AMG isn’t just about driving—it’s about belonging to an exclusive club. From the moment you take delivery, you’re treated like a VIP. Mercedes offers a concierge service, 24/7 roadside assistance, and even a mobile service option where technicians come to your home or office for maintenance.
The G63 also comes with a 4-year/50,000-mile warranty, including complimentary scheduled maintenance for the first two years. And because it’s an AMG, you get access to exclusive events, track days, and owner experiences—like driving your G63 on a professional race circuit with an instructor.
Resale Value and Depreciation
One of the biggest advantages of the G63 AMG is its strong resale value. Unlike many luxury SUVs that depreciate quickly, the G-Class holds its value remarkably well. According to industry data, a 2021 G63 AMG retains about 70-75% of its value after three years—far better than competitors like the Range Rover Sport or BMW X5 M.
This is due to several factors: limited production, high demand, and the G-Class’s iconic status. It’s not uncommon to see used G63 AMGs selling for nearly new prices, especially if they’re well-maintained and have low mileage.
Fuel and Maintenance Costs
Of course, owning a G63 AMG isn’t cheap. Fuel costs are high, and premium gasoline is required. Maintenance can also be pricey—especially if you use a Mercedes dealership. However, many owners find that the joy of driving outweighs the costs. Plus, with proper care, the G63 is known for its reliability and longevity.
Conclusion: The Ultimate Luxury Performance SUV
The 2021 Mercedes Benz G63 AMG is more than just a vehicle—it’s a lifestyle statement. It combines the raw power of a sports car with the rugged capability of an off-roader and the refined luxury of a flagship sedan. Whether you’re navigating city streets, carving up mountain roads, or exploring remote trails, the G63 AMG does it all with confidence and style.
It’s not for everyone. The price tag starts around $150,000, and options can push it well over $200,000. But for those who can afford it, the G63 AMG delivers an unmatched blend of performance, prestige, and personality. It’s a vehicle that turns every drive into an event, and every arrival into a moment.
In a world of increasingly similar SUVs, the G63 AMG stands out—not just for what it can do, but for what it represents. It’s bold, it’s beautiful, and it’s built to last. If you’re looking for the ultimate luxury performance SUV, the 2021 Mercedes Benz G63 AMG is hard to beat.
