Whether you’re conquering city commutes or remote adventures, the G63 offers unmatched prestige and performance.
The 2021 Mercedes-Benz AMG G63 isn’t just another luxury SUV — it’s a statement. It’s the car that says, “I don’t compromise on style, power, or capability.” For over four decades, the G-Class has been synonymous with adventure, military use, and elite luxury. And in 2021, Mercedes-AMG gave it a serious upgrade — one that keeps its rugged DNA alive while embracing modern innovation.
If you’ve ever dreamed of cruising through the Alps with the windows down, then tearing up a desert trail with zero hesitation, the G63 delivers on both dreams.

It’s about feeling unstoppable, whether you’re navigating snow-covered mountain passes or dropping the kids off at school.
What makes the 2021 model stand out? First, its heart: a hand-built 4.0-liter V8 biturbo engine that roars to life with 577 horsepower and 627 lb-ft of torque. Second, its brains: an intelligent all-wheel-drive system and three locking differentials that make short work of mud, sand, and rock climbs.

Quick Answers to Common Questions
Is the 2021 G63 fuel-efficient?
No, not really. With a combined EPA rating of 13 mpg, it’s one of the least fuel-efficient luxury SUVs. But for many owners, performance and capability outweigh fuel economy concerns.
Can the G63 go off-road?
Absolutely. With its three locking differentials, high ground clearance, and off-road driving modes, the G63 excels in challenging terrain like mud, sand, rocks, and steep inclines.
How much does a 2021 G63 cost?
New MSRP starts around $156,000. Used prices vary, but well-maintained examples typically range from $120,000 to $140,000 depending on mileage and options.
Does the G63 have a manual transmission?
No. The G63 uses an AMG SPEEDSHIFT TCT 9-speed automatic transmission. Manual transmissions aren’t offered on the G-Class since 1988.
Is the G63 reliable?
Overall, yes. While complex systems like the differential locks and air suspension may require occasional maintenance, the G63 is mechanically robust when properly cared for. Regular servicing is key.

The Iconic Design That Commands Attention
There’s nothing subtle about the G63. Its boxy shape, upright stance, and signature circular headlights have remained largely unchanged since the 1970s — and for good reason. This design isn’t just nostalgic; it’s functional. The high roofline provides excellent visibility, while the flat hood and reinforced frame ensure durability in tough conditions.
In 2021, Mercedes added subtle refinements. The grille now features a more aggressive mesh pattern, and the front bumper includes wider fenders and larger air intakes. LED headlights come standard, offering improved night visibility and a futuristic glow. At the rear, a prominent spare tire (yes, really) sits proudly behind a flip-up door — a nod to its off-road roots.
But it’s not all function. The G63 comes in a range of exterior colors, including exclusive shades like Selenite Grey Magno and Obsidian Black Magno. Optional body kits from AMG can add even more muscle, with flared wheel arches and carbon fiber accents.
For those who want something truly unique, Mercedes offers the Night Package or AMG Exterior Carbon Fiber Package. These add glossy black finishes, carbon fiber mirror caps, and a sportier look without losing the G-Wagen’s identity.
Performance That Drives Like a Beast
Under the hood, the 2021 G63 packs a punch. The 4.0L twin-turbocharged V8 engine is a masterpiece of engineering. Thanks to two turbochargers working in tandem, lag is minimized, and power delivery is smooth and immediate. You don’t need to rev high to feel the surge — just tap the accelerator, and the car lunges forward.
Zero to 60 mph happens in just 4.5 seconds. That’s faster than most sports cars. Top speed is electronically limited to 130 mph, but in real-world driving, you’ll rarely hit that limit.
What’s even more impressive? The transmission. An AMG SPEEDSHIFT TCT 9-speed automatic gearbox shifts quickly and smoothly. In Comfort mode, it prioritizes fuel efficiency and quiet cruising. Switch to Sport or Race mode, and everything changes — throttle response sharpens, gear changes become quicker, and the exhaust note deepens into a throaty growl.
And let’s talk about traction. The G63 uses a 4MATIC+ all-wheel-drive system that actively distributes torque between axles. Combined with the three differential locks (front, center, and rear), this means maximum grip in any condition.
Whether you’re stuck in snow, climbing a rocky incline, or crossing a shallow river, the G63 doesn’t flinch. The optional Dynamic Select allows you to switch between modes like Comfort, Sport, Sport+, Individual, and Trail. Each setting adjusts suspension damping, steering weight, and throttle mapping to match your driving style or terrain.
Driving Experience Tips
- Use Trail Mode: When going off-road, select Trail mode to optimize low-speed control and enhance stability.
- Engage Differential Locks: On slippery surfaces, manually lock the center diff for better power distribution.
- Adjust Suspension: Use the AIRMATIC air suspension to raise ride height for rough terrain or lower it for highway comfort.
Luxury Redefined Inside the Cabin
Step inside the G63, and you’re greeted by a cockpit that feels more like a five-star hotel room than a vehicle. The dashboard is dominated by dual 12.3-inch screens — one for the instrument cluster, the other for infotainment. The displays are crisp, responsive, and customizable.
Mercedes’ latest MBUX (Mercedes-Benz User Experience) system powers the interface. Voice commands work well — say “Hey Mercedes,” and you can control navigation, climate, music, and more. Apple CarPlay and Android Auto come standard, ensuring seamless smartphone integration.
Materials matter. Leather upholstery is available in multiple colors, including black, saddle brown, and magma grey. Alcantara headliners and carbon fiber trim give it a sporty edge. Heated and ventilated front seats are standard, while massaging seats and heated armrests elevate comfort further.
For audiophiles, the Burmester 3D surround sound system (available as an option) delivers studio-quality audio. It includes 15 speakers and a 710-watt amplifier, turning the cabin into a concert hall.
Cargo space is generous thanks to the rear seats that fold flat. With them down, you get nearly 68 cubic feet of storage — enough for camping gear, skis, or a full-sized cooler.

Technology and Safety: Smart and Secure
The 2021 G63 isn’t just powerful — it’s smart. The MBUX system learns your habits and suggests actions, like rerouting based on traffic or adjusting climate settings before you arrive home.
Navigation includes real-time traffic updates and predictive route guidance. Over-the-air software updates keep the system fresh throughout the car’s lifespan.
On the safety front, Mercedes equips the G63 with a suite of driver-assistance features. These include:
- Active Brake Assist
- Blind Spot Monitoring
- Cross-Traffic Alert
- Active Lane Keeping Assist
- Traffic Sign Assist
- Parking Assist with 360-degree camera
Emergency braking and collision warnings help prevent accidents. If a crash is unavoidable, the car automatically alerts emergency services and shares your location.
For off-road adventures, the G63 includes a crawl control system. Think of it as cruise control for rough terrain — the car manages speed and braking, allowing you to focus on steering.
Tech Tip: Mastering MBUX
To get the most out of your MBUX system:
- Say “Hey Mercedes” clearly when the microphone icon appears.
- Use the touchpad on the center console to navigate menus quickly.
- Update your software regularly via Wi-Fi to access new features.
Off-Road Capability Without Compromise
Despite its luxury trappings, the G63 is built tough. The ladder-frame chassis is made of high-strength steel, providing exceptional rigidity. Ground clearance is generous, especially when the AIRMATIC suspension is raised.
The three locking differentials are the secret weapon. In extreme conditions, they ensure every wheel gets power — no slipping, no spinning out. Combine this with the selectable drive modes, and the G63 can tackle obstacles most SUVs would shy away from.
Optional accessories make it even more capable. A winch-ready front bumper, auxiliary lighting, and protective skid plates help in remote environments. For desert runs, sand driving tires are available.
Even in urban settings, the G63 shines. The adaptive suspension smooths out potholes and speed bumps, while the all-wheel-drive system ensures confidence in rain or light snow.
Off-Road Checklist
Before heading off-grid:
- Check tire pressure (lower for soft terrain)
- Fill up on water and fuel
- Pack recovery gear (rope, shovel, gloves)
- Inform someone of your route
- Use Trail mode and engage diff locks when needed
Ownership Experience and Resale Value
Owning a G63 is more than just driving — it’s part of a lifestyle. Owners often gather at off-road meetups, luxury car shows, or even private trail rides. There’s a sense of community among G-Class fans.
Maintenance is straightforward. Mercedes offers comprehensive service plans, and parts are widely available. However, repairs can be costly due to the car’s complexity and exclusivity.
That said, the G63 holds its value exceptionally well. According to Kelley Blue Book, a used 2021 G63 retains over 70% of its original value after three years. Low production numbers and high demand contribute to this strong resale performance.
Warranty coverage includes:
- 4 years / 50,000 miles basic warranty
- 4 years / 50,000 miles powertrain warranty
- Rust perforation warranty for 12 years
Pro Tip for Buyers
When purchasing a used G63, always request a full service history and inspect for previous off-road damage. The differential locks and suspension components wear differently based on use.
Frequently Asked Questions
What makes the G63 different from the regular G-Class?
The G63 is the high-performance version, featuring a more powerful V8 engine, sport-tuned suspension, AMG styling cues, and enhanced interior materials. The standard G-Class uses a less powerful engine and lacks the AMG-specific upgrades.
Can I tow with the G63?
Yes. The G63 has a towing capacity of up to 7,000 pounds when properly equipped, making it suitable for trailers, boats, or campers.
Are there hybrid versions of the G63?
Not yet. As of 2021, the G63 remains a pure internal combustion engine vehicle. Rumors of an electric or hybrid G-Wagen are under development, but no official release date exists.
How loud is the G63 inside?
In Comfort mode, it’s very quiet — almost whisper-quiet. But when you press the accelerator, that V8 roar becomes noticeable. Many owners enjoy the sound, while others find it too aggressive.
Is the G63 easy to park?
It’s large and tall, so parallel parking requires patience. However, the 360-degree camera and parking assist make maneuvering easier in tight spaces.
What’s the best color for resale?
Neutral tones like Polar White, Selenite Grey, and Obsidian Black tend to hold value better. Bright colors or uncommon finishes may appeal to some buyers but could limit future resale options.
