2025 G-Class Showdown: G 63 vs G 580 EQ vs G 550

The 2025 Mercedes-Benz G-Class arrives with an exciting choice for luxury SUV enthusiasts. The expanded lineup features three distinct variations: the performance-driven Mercedes-AMG G 63, the pioneering all-electric G 580 with EQ Technology, and the updated G 550. Each embodies the iconic G-Class spirit, blending rugged capability with premium refinement.

These models cater to different driving preferences and priorities. Making the right choice requires understanding their unique strengths, from powertrain philosophies to specialized off-road technologies. This comparison focuses on these key differences.

While all share the legendary G-Class foundation—unmistakable design, sophisticated interiors, and inherent off-road readiness—their individual approaches set them apart. Let's examine the data extracted directly from the latest model information to help identify the G-Class that best aligns with your expectations.

Powertrain and Performance

The core distinction lies under the hood, or within the frame for the G 580. The G 550 utilizes a smooth 3.0-litre inline six-cylinder engine boosted by a 48-volt mild hybrid system. This setup delivers 443 hp and 413 lb-ft of torque.

It's intelligently supplemented by an integrated starter generator (ISG). This provides an additional temporary boost of 20 hp and 148 lb-ft for improved responsiveness and efficiency. The ISG also enables energy recovery and smoother engine start/stop operation.

Power is managed through the efficient 9G-TRONIC automatic transmission. It's specifically adapted for the G 550, featuring a wide gear ratio spread for comfortable, quiet driving and optimized fuel consumption.

The Mercedes-AMG G 63 elevates performance significantly. Its Handcrafted AMG 4.0L V8 biturbo engine also features 48-volt mild hybrid technology and the ISG boost. This potent combination produces a commanding 577 hp and 627 lb-ft of torque.

The G 63 employs the AMG SPEEDSHIFT TCT 9G transmission. It’s designed for exceptionally short shift times and offers a double-declutching function for a more engaging drive. It adapts characteristics based on the selected AMG DYNAMIC SELECT program.

Breaking new ground, the G 580 with EQ Technology employs four individually controlled electric motors. Integrated two per axle, they generate a combined 579 hp and a substantial 859 lb-ft of torque available instantly. This innovative drive concept allows precise torque distribution via vectoring.

In acceleration from 0-100 km/h, the AMG G 63 leads at a rapid 4.4 seconds. The all-electric G 580 EQ follows closely at an estimated 4.7 seconds. The G 550 achieves the sprint in a respectable 5.4 seconds.

Top speeds are electronically limited. The G 63 reaches 220 km/h, the G 550 hits 210 km/h, and the G 580 EQ is limited to 180 km/h.

Off-Road Capabilities Compared

All three models retain essential G-Class hardware: a robust ladder frame (modified for G 580), independent front suspension, and a solid rear axle (De Dion design for G 580). The G 550 and G 63 feature three mechanical differential locks offering 100 percent locking effect.

These mechanical locks are operable individually in both HIGH and LOW RANGE. The G 580 uses virtual differential locks via torque vectoring. This system automatically distributes torque without driver intervention for optimal traction.

Selectable LOW RANGE off-road gear reduction is standard across the board. It significantly increases torque at the wheels for tackling difficult terrain (2.93:1 ratio for G 550/G 63, 2:1 for G 580).

Adaptive adjustable damping is standard on the G 550 and G 580. It continuously adjusts to conditions for enhanced control and comfort. The G 63 comes standard with AMG RIDE CONTROL suspension featuring adaptive damping.

The G 63 can be optioned with advanced AMG ACTIVE RIDE CONTROL suspension. This uses hydraulic elements for active roll stabilization and improved wheel articulation, enhancing both comfort and handling during dynamic maneuvers.

The G 580 boasts the highest maximum fording depth at 850 mm. This surpasses the impressive 700 mm capability of the G 550 and G 63. Ground clearance is similar (G 580: 250 mm; G 550: 241 mm).

Approach and departure angles are comparable (G 550: 31°/30°; G 580: 32°/30.7°). Unique to the electric model are G-TURN for on-the-spot rotation and G-STEERING for a tighter off-road turning circle.

The G 580 also features an intelligent off-road crawl function with three speed levels (Slow, Variable, Fast). Its special underbody protection uses a lightweight, rigid carbon-material mix.

All models benefit from DYNAMIC SELECT drive programs. These include dedicated off-road modes like "Trail," "Rock," and "Sand" to optimize performance for specific surfaces.

Technology and Interior Highlights

Inside, the G-Class DNA is evident. All variants feature the standard MBUX infotainment system with dual 12.3-inch displays, touch control, and intelligent voice assistance understanding about 20 G-Class specific commands. MBUX Augmented Reality for Navigation is included.

Standard comforts include the Burmester 3D Surround Sound System with Dolby Atmos, KEYLESS-GO, 64-colour ambient lighting, and climate-controlled cupholders. A comprehensive suite of driver assistance systems is also standard equipment.

These include Active Distance Assist DISTRONIC, Active Brake Assist, Active Lane Keeping Assist, Blind Spot Assist, PRE-SAFE, ATTENTION ASSIST, Traffic Sign Assist, and the Parking Package with a 360-degree camera. Active Parking Assist is also included.

Newly available systems for the G-Class include Active Steering Assist (up to 160 km/h), Active Emergency Stop Assist, and Route-Based Speed Adaptation, further enhancing driver support and safety.

Distinctions include AMG-specific interior elements (performance steering wheel, unique upholstery) and exterior styling (bumpers, grille, crest) for the G 63. The G 580 features exclusive aerodynamic elements, the G-ROAR sound experience, and an optional rear-door Design Box.

The 2025 G 580 launches exclusively as the EDITION ONE. It features unique blue accents, standard AMG Line and Night Package, and specific MANUFAKTUR Silver Pearl/Black Nappa leather upholstery.

All models benefit from improved aerodynamics and offer extensive customization through the expanded MANUFAKTUR program. This allows for unique paint, leather, and trim combinations to personalize your G-Class.

Choosing between the 2025 models depends on your priorities. If unparalleled V8 performance is paramount, the AMG G 63 stands out. For those embracing electric mobility with unique off-road innovations, the G 580 EQ offers a compelling package.

The G 550 provides a superbly balanced blend of traditional capability, modern mild-hybrid efficiency, and luxurious refinement. Each represents the pinnacle of the luxury off-road experience, tailored for a distinct driver yet unified by the indomitable G-Class spirit.
