The G-Class enters 2021 the same as it enters every model year: as the king of the Mercedes mountain. Forget the S-Class and its classy extravagance; the big, boxy G is the pinnacle of ostentatious excess. It's dramatic appearance arguably makes a louder statement than even the Rolls Royce and Bentley SUVs.

The G-Class was last redesigned in 2019, making it a newborn compared to the nearly 40 years its predecessor went without any ground-up refreshes. For its second year on the market, Mercedes makes the 12.3-inch digital instrument cluster standard on all models; G63 models now get standard wireless device charging.

Personalization will reach new heights this year thanks to an expanded color palette of 34 exterior colors and 54 interior colors, available through the new G Manufaktur customization package. All told, Mercedes says there can be over one million individual combinations of G-Class.

The G is only sold in one of two versions: the less insane G550 and the over-the-top G63 AMG. The AMG is the rowdier option, but otherwise both models share the same key components and features.

Pricing begins at a shade over $130,000 for a G550 and at about $157,000 for a G63. With options, the MSRP can inflate to over $200,000.

Both G-Class models use the same twin-turbo 4.0-liter V-8, but the G63 turns up the wick in order to draw out about 150 more horsepower than the G550; it'll do 0-60 mph in just 4.5 seconds, or about a full second faster than its lesser sibling. Either way, expect serious power and depressing fuel economy.

All that horsepower gets routed through a nine-speed automatic transmission on its way to a four-wheel-drive system. It's engaged full-time, employing a fixed 40/60 power split between the front and rear axles. A trio of locking differentials as well as a dedicated low gear transfer case ensures serious off-road capability.

An independent front suspension - which was only introduced in 2019 - helps tidy up the handling, but out back there's a less sophisticated live axle design, which enhances performance on the trail but doesn't improve ride and handling while driving on asphalt.

Despite its hulking size, the G-Class only seats five. The rear passengers enjoy nearly 40 inches of legroom and excellent views out the massive windows.

The live axle forces a higher load floor in the cargo area, which is why there's only 38 cubic feet available; other SUVs of similar size offer superior space. Fold down the G's seats and 69 cubic feet of space opens up.

The full complement of Mercedes active-safety features is standard. That includes automatic emergency braking, active lane control, a driver attention monitor, adaptive cruise control, blind-spot monitoring, rear cross-traffic alert, and a driver attention monitor.

An active parking assist is standard as well: it lets the car maneuver itself in and out of both parallel and perpendicular parking spaces The G63 goes a step further with a standard surround-view camera.

Low volume precludes the G-class from getting crash-tested, but we have full confidence this 5,500-pound SUV would hold up well in a collision.

This year, the 12.3-inch digital instrument cluster has been made standard. Directly to the right of it is the 12.3-inch display screen for the MBUX infotainment system. Together, the two screens give the impression of one single 25-inch screen.

The infotainment isn't controlled via touchscreen. Instead, Mercedes offers drivers a choice: a haptic touchpad or rotary knob located in the center console or voice command. The steering wheel features both physical buttons as well as small haptic surfaces that let drivers toggle infotainment menus or adjustment the digital cluster.

Apple CarPlay and Android Auto capability comes standard, and navigation does as well. Tunes and directions are played out through a 15-speaker Burmester audio system.

The more affordable of the two G-Class models is still an expensive, opulent, and well-equipped SUV. Features like leather upholstery and heated front seats with memory function and multi-way power adjustments are standard. Also included are heated rear seats, power-folding mirrors, tri-zone climate control, and a sunroof.

On the outside, the G550 sports 19-inch wheels and full LED lighting. The big windows are made of acoustic-laminated glass that silence outside noise and help insulate the cabin. The standard electric windshield eliminates the need to pull out the ice scraper on frosty mornings.

With such a thorough list of standard features, there's only a few interior packages available. They come with features such as ventilated front seats, Nappa leather, and massaging seats. The $12,200 Exclusive Interior Package Plus is the most comprehensive of these and, along with the aforementioned upgrades, offers diamond-quilted upholstery and rapid-heating for the front seats.

Standalone options include a $250 heated steering wheel and $1,400 adaptive dampers.

The G63 is much like the G550 save the handcrafted 577-horse twin-turbo V-8 hiding under the hood. Accompanying the big motor are touches such as an adaptive suspension, side-pipe exhaust, flared fenders, high-performance brakes, and exclusive drive modes. The interior is classed up with Nappa leather, wireless device charging, and a surround-view camera.

As for options, adventurous types can by the $3,050 AMG Trail Package, which includes an off-road optimized suspension, and 20-inch wheels. The Exclusive Interior Package Plus is again available, but the price point is reduced to $7,200.
