A Closer Look at the AMG G 63 Powertrain
The 2025 Mercedes-AMG G 63 is anything but subtle. Every angle, every rev, and every feature makes a statement. At Limited Spec, Miami’s top luxury dealership, we know what our clients expect—power, prestige, and performance wrapped in a bold silhouette. This SUV doesn’t just drive, it dominates—both off-road and on. Let’s take a closer look under the hood at what makes the AMG G 63 powertrain so jaw-droppingly capable.
585 Horses of Brute Force, Refined
The heart of this G-Wagon is the handcrafted 4.0-liter AMG V8 biturbo engine. Producing 577 horsepower and 627 lb-ft of torque, it’s tuned for pure excitement. This unit is also assisted by an electric starter-generator, which smooths low-speed response and adds torque without fuel. That blend of hybrid tech and classic V8 strength ensures this luxury SUV hits 60 mph in just 4.2 seconds.
Furthermore, the “hot inside V” twin-turbo configuration enhances responsiveness by reducing the distance between exhaust and intake. With quicker spooling and up to 14.5 psi of boost, turbo lag is barely noticeable.
Powertrain Tech That Goes Beyond the Pavement
More than just raw numbers, the AMG G 63 powertrain integrates a 9-speed AMG SPEEDSHIFT TCT transmission that delivers rapid gear changes without jerking or hesitation. This system adapts to driving style, whether you’re launching at a green light or cruising through Brickell.
To optimize performance in any environment, the AMG Performance 4MATIC all-wheel-drive system maintains a 60:40 rear-wheel bias. Paired with a 2-speed transfer case and three individually lockable differentials, it provides unmatched control on slick streets and sandy trails alike.
Agility and Comfort Meet on Every Terrain
The 2025 G 63 doesn’t shy away from trails. In fact, it welcomes them.
Thanks to AMG RIDE CONTROL with adaptive damping, you can switch between Comfort, Sport, or Sport+ modes. Each setting adjusts the suspension, ensuring the perfect balance whether you’re on uneven backroads or highway straightaways.
Some standout off-road figures include:
- 9.5 inches of ground clearance
- Up to 27.5 inches of fording depth
- Ability to climb 45-degree inclines
- Capability to traverse 35-degree slopes sideways
This isn’t just a city cruiser. It’s a mountain goat wrapped in luxury leather.
