Mercedes G500 4×4² Complete Review: Specs, Performance, Price

The Mercedes-Benz G500 4×4² stands as a pinnacle of automotive engineering, transforming the iconic G-Class into an extreme off-road machine that defies conventional limits. This concept vehicle, introduced as a bolder alternative to the already formidable standard G-Wagen, elevates ground clearance, approach angles, and power delivery to unprecedented levels while maintaining a touch of luxury. Drawing from advanced portal axle technology, it conquers terrains that leave regular SUVs grounded, yet surprises with composed road manners.

Engineering Innovations Behind the Elevation

At the heart of the G500 4×4²’s dominance lies its innovative **portal axle system**, a design borrowed from heavy-duty off-roaders like the G63 6×6. These axles position the wheels lower relative to the axle housing via integrated hub gears, dramatically increasing ride height without compromising suspension travel. The result? A staggering **450mm of ground clearance**—more than double the standard G-Class’s 210mm—allowing it to surmount obstacles up to 17.7 inches high and wade through water depths reaching 39.4 inches (1 meter).

This setup also boosts key off-road metrics: approach angle climbs to 52 degrees (from 36 degrees), departure angle to 54 degrees (from 27 degrees), and breakover angle expands significantly, enabling the vehicle to scramble over rocks, logs, and steep inclines that halt lesser 4x4s. Skid plates protect the underbody, ensuring vital components remain unscathed during aggressive trail runs.

Powertrain: Twin-Turbo V8 Muscle

Propelling this behemoth is a **4.0-liter twin-turbocharged V8 engine**, derived from Mercedes-AMG’s M178 architecture. In this application, it delivers approximately **416 horsepower** and **450 lb-ft of torque**, propelling the three-tonne SUV to 60 mph in under six seconds, with a top speed electronically limited to 130 mph (or 99 mph on off-road tires). Paired with a seven-speed automatic transmission and the G-Class’s signature three locking differentials plus low-range transfer case, power distribution is precise and relentless.

Reviewers note the engine’s eagerness across all gears, providing seamless acceleration despite the vehicle’s mass. The exhaust, with four prominent tailpipes, emits a thunderous roar that amplifies the sense of occasion. While the gearbox can feel slightly reluctant to paddle-shift responses, it handles the torque admirably, ensuring no shortage of forward thrust.

On-Road Dynamics: Surprisingly Nimble Giant

Despite its towering stance and widened track (over 2 meters), the G500 4×4² exhibits remarkable composure on pavement. Electronically adjustable dampers offer Comfort and Sport modes, smoothing out impacts or sharpening responses as needed. The increased track width enhances stability, allowing it to carve corners with enthusiasm that outpaces standard G-Class models—some testers claim up to 10 mph faster through bends.

Steering, while initially vague as per G-Class tradition, builds confidence with feedback, tucking the front end precisely. Ride quality benefits from the dampers, though the sheer scale demands respect at higher speeds. Off-road tire options prioritize grip over refinement, activating speed limiters for safety.

Off-Road Supremacy in Action

Where the G500 4×4² truly shines is off the beaten path. Testers have tackled dried riverbeds, mud-choked jungles, rocky slopes, and boulder-strewn tracks that forced standard G-Wagens to detour. In one trial near Granada, Spain, it navigated ‘the jungle’—a narrow, obstacle-laden valley—effortlessly, while companions struggled. Portal axles reduce drivetrain stress via hub reduction, enhancing durability under extreme loads.

• Riverbed conquests: Climbs over tree trunks and irregular rocks with ease.
• Steep inclines: Superior angles prevent high-centering.
• Mud and water: 1m wading depth and traction systems dominate.

The three locking diffs and low-range gearing provide surgical control, making impossible terrain feel routine.

Interior Luxury Amidst Ruggedness

Climbing aboard requires effort—doorsills are chest-high—but inside awaits G-Class opulence. Lavish leather, wood accents, and modern infotainment blend old-world charm with contemporary tech. Space remains tight due to the boxy design, prioritizing robustness over roominess, yet four adults fit comfortably for adventures.

Cargo area accommodates gear, and the high seating position offers commanding views. While not spacious by SUV standards, the exclusivity compensates.

Production Potential and Pricing

Though billed as a concept, the G500 4×4² drove like a production-ready vehicle, hinting at Mercedes’ intent. Following the G63 6×6’s success (over 100 sold at £370,000 each), estimates pegged this model’s price around £250,000. Demand from enthusiasts promised quick sell-outs, blending rarity with capability.

Pros and Cons at a Glance

• Pros: Unmatched off-road ability, potent V8, stable handling, luxurious cabin.
• Cons: Tight interior, heavy weight, high cost, vague low-speed steering.

Frequently Asked Questions (FAQs)

What makes the portal axles special?

Portal axles use gears in the wheel hubs to elevate the body, boosting clearance without sacrificing suspension articulation.

Is the G500 4×4² street-legal?

Yes

, with road tires and speed limiters, it’s drivable on public roads, though its size suits open spaces best.

How does it compare to the G63 6×6?

The 4×4² is shorter, more agile, with similar axles but four wheels instead of six, at a lower price point.

Was it ever produced?

Limited units were made available post-concept, targeting ultra-exclusive buyers.

What’s the fuel economy like?

Expect low teens mpg given the V8 and weight; it’s built for performance, not efficiency.

Legacy of an Off-Road Icon

The G500 4×4² cements the G-Class’s reputation as an indomitable force, proving luxury and extremity coexist. It inspired future models, pushing boundaries for enthusiasts seeking the ultimate 4×4 adventure.
