Mercedes G63 4x4 Squared: The Off-Road Beast Explained

Author: Mo | 021 Auto Leasing Last Updated: March 2026

The Mercedes G63 AMG 4x4 Squared is the most extreme production G-Wagon ever built. It takes the standard G63's 577-hp handcrafted V8 and bolts it to a chassis with portal axles, a raised suspension delivering nearly 18 inches of ground clearance, and off-road geometry that rivals purpose-built trail machines. New MSRP started around $250,000, but with only roughly 300 units produced for the U.S. market per year and collector-level demand, used examples now trade between $234,000 and $400,000+ depending on spec and mileage.

Mercedes has described the 4x4 Squared as the last of its kind — a final send-off for the combustion-powered extreme G-Class before the brand's electrification push. That positioning, combined with razor-thin supply, makes this one of the few vehicles that's appreciating rather than depreciating. Here's everything you need to know.

What Is the G63 4x4 Squared and How Does It Differ From the Standard G63?

The defining feature is the portal axle system. In a standard G63, the axle sits at the center of the wheel hub. In the 4x4 Squared, the axle is mounted higher — above the wheel center — using a gear reduction at each hub to transmit power downward. This single engineering change raises the entire vehicle by roughly 8 inches without altering the center of gravity as drastically as a simple lift kit would.

The visual difference is immediately obvious: wider fender flares to accommodate the increased track width, a noticeably taller ride height, and massive 22-inch wheels wrapped in 325/55 all-terrain tires. The 4x4 Squared looks like a standard G63 on stilts — because it essentially is, but with purpose-built engineering rather than aftermarket modifications.

Under the hood, the powertrain is identical to the standard G63: a 4.0-liter AMG V8 biturbo producing 577 horsepower and 627 lb-ft of torque, paired with the AMG SPEEDSHIFT TCT 9-speed automatic and permanent 4MATIC all-wheel drive. The 4x4 Squared isn't faster than a regular G63 — it's built for where you take it, not how quickly you get there.

G63 4x4 Squared Off-Road Specs: The Numbers That Matter

Here's where the 4x4 Squared leaves every other luxury SUV behind:

Ground clearance: Approximately 17.7 inches — nearly double the standard G63's 9.5 inches. For context, a Jeep Wrangler Rubicon has about 10.8 inches.

Approach angle: Approximately 51° versus the standard G63's 31°. This means the 4x4 Squared can climb steeper inclines without scraping the front bumper.

Departure angle: Approximately 44° versus 30°. Steep descents and rock ledges that would catch a standard G-Class's rear end are cleared easily.

Three locking differentials — front, center, and rear — shared with the standard G-Class. Combined with the portal axles and low-range gearing, this gives the 4x4 Squared genuine Moab-level off-road capability in a vehicle with a Nappa leather interior and Burmester sound system.

The trade-off is on-road comfort. The raised ride height and all-terrain tires create more body roll in corners and a firmer ride over highway expansion joints. This isn't a daily commuter for most people — though plenty of owners drive them daily anyway.

The 4x4 Squared also sits considerably taller at the curb, which changes the vehicle's proportions in a way that draws even more attention than a standard G63. Parking garages can be tight — the extra height means some covered structures won't accommodate it. Fuel economy, already poor on the standard G63 at 13/16 MPG city/highway, gets slightly worse with the larger tires and aerodynamic penalty of the wider body.

None of this matters to the target buyer. If you're shopping a 4x4 Squared, you've already accepted these trade-offs in exchange for something no other factory luxury SUV can deliver.

How Much Does a G63 4x4 Squared Cost?

New MSRP (2022–2024 production): Started around $250,000 base. Well-optioned examples with MANUFAKTUR paint, AMG Night Package, and premium interior upgrades pushed window stickers past $280,000–$300,000. Dealer markups of $50,000–$100,000+ were standard — most buyers paid $300,000–$375,000 out the door.

Used market (as of early 2026): Auction and private sale data shows a range of $234,000 (a 2023 model sold in late 2025) to $445,000 (a low-mile 2022 sold in early 2023 when demand peaked). The current average transaction price sits around $299,000. A recent listing: a 2024 model in MANUFAKTUR Dark Olive Green Magno with 325 miles was priced at $409,000.

Collector trajectory: Unlike most vehicles, the 4x4 Squared is appreciating on the used market. With U.S. production limited to roughly 300 units per year across only three model years (2022–2024), total supply is extremely constrained. Mercedes' positioning of the vehicle as the last combustion extreme G-Class adds a scarcity narrative that's driving collector interest.

The standard G63 at $195,500 MSRP is roughly $55,000 less at base. For most buyers, that's the right call — the standard G63 is spectacular on its own. The 4x4 Squared is for the buyer who wants the most extreme factory G-Wagon ever made and views it as part vehicle, part investment.

G63 4x4 Squared vs. Standard G63 AMG vs. 6x6: Which Is Worth It?

These three vehicles share DNA but serve very different buyers:

Standard G63 AMG ($195,500 new): The daily-drivable performance G-Wagon. 577 hp, luxurious interior, strong off-road capability for a luxury SUV. Depreciates roughly 27% over three years. Best for buyers who want the G-Class experience without extremes. Read our full Mercedes G63 AMG buyer's guide for pricing and spec details.

G63 4x4 Squared ($250,000+ new, ~$300K used): The off-road extreme. Portal axles, raised suspension, genuine trail capability. Limited production (~300/year U.S.), appreciating values. Best for collectors, serious off-road enthusiasts, and buyers who want the rarest factory G-Wagon currently available.

G63 AMG 6x6 (discontinued, $600K–$1M+ used): The ultimate collector piece. Six wheels, six-wheel drive, military-grade engineering. Production ended years ago with extremely limited numbers built. Pure collector car territory — not a daily driver. See our Mercedes 6x6 guide for the full breakdown.

If you're cross-shopping, the question is simple: do you actually need the off-road capability? If yes, the 4x4 Squared delivers in ways the standard G63 can't. If the appeal is primarily visual and status-driven, save $100K+ and get the standard G63 — then lease it through a broker to keep your costs predictable.

One more consideration: the 4x4 Squared is not being offered for 2025 or 2026 as of this writing. The refreshed 2025+ G63 uses a new platform with a 48V mild hybrid system, and Mercedes has not announced a 4x4 Squared variant for it. That means the 2022–2024 models may be the only 4x4 Squared generation ever produced — a factor that's already driving collector premiums higher.

How to Find a G63 4x4 Squared for Sale

The 4x4 Squared is not a vehicle you'll find by walking into your local Mercedes dealer. With only ~300 produced per year for the entire U.S. market, most dealers received one or two allocations at most — and those were spoken for before they arrived.

Where to look: Edmunds currently lists about 58 used 4x4 Squared examples nationwide. Cars.com, duPont Registry, and Bring a Trailer are also active marketplaces. But listings move fast — desirable specs (MANUFAKTUR colors, low miles, clean history) often sell within days.

What to inspect: Portal axles are the most unique and most expensive component to service. Check for any signs of off-road abuse — undercarriage scrapes, bent skid plates, damaged portal axle boots. If the vehicle was actually used off-road (many aren't), get a specialist inspection from a Mercedes dealer familiar with the 4x4 Squared, not just any independent shop.

Also verify the MANUFAKTUR paint condition if applicable — matte finishes require specific care, and a poorly maintained Magno finish can cost $10,000+ to correct. Check for uneven panel gaps (a sign of body work after an unreported incident), and confirm the VIN matches the build sheet for the options claimed. On a $300K+ vehicle, every detail matters.

Broker advantage: A broker accesses inventory before it hits public listings, including dealer-to-dealer trades and private sales. We recently helped a client locate a 2023 4x4 Squared in MANUFAKTUR Cardinal Red that never made it to public listing — the selling dealer had it in their back lot as a recent trade-in. Our client secured it at $272,000 — roughly $25,000 under comparable listings at the time — because we reached the dealer before they'd photographed and listed it.

That's the value of a broker network on a vehicle this rare. It's not just about negotiating price — it's about seeing inventory that other buyers never know exists.

Can you lease a G63 4x4 Squared?

Technically yes, but it's rare. Mercedes-Benz Financial Services does not include the 4x4 Squared in national lease incentive programs, so any lease would be structured at full retail rates with very high payments. Most 4x4 Squared buyers purchase outright or finance.
