2024 Mercedes-AMG GLS63 defines luxury SUV with a hefty price

James Raia

Big and bold and wearing a front-grille badge the size of a serving platter, the 2024 Mercedes-AMG GLS63 sport utility vehicle is all about luxury, power and excess all in no uncertain terms.

The biggest SUV from the manufacturer’s high-performance subsidiary, the three-row family hauler does nothing subtle. It features a 4.0-liter twin-turbocharged V8 with hybrid assistance and delivers 603 horsepower. It generates another 21 horsepower from the Integrated Starter Generator (ISG). It’s a 48-volt auxiliary on-board motor that operates an electrical system giving a boost power to several systems.

Operated via a nine nine-speed automatic transmission, the SUV advances from 0-to-60 miles per hour in 4.1 seconds. The top speed is pegged at 174 miles per hour and the vehicle’s versatility is further defined by its towing capacity of 7,700 pounds. Gas mileage averages are 14 miles per gallon in city driving, 18 mpg on the highway.

For driving pursuits whose satisfaction isn’t met by general performance, Mercedes-AMG has enhanced the SUV with software updates for improved roll stabilization and air suspension for better handling and comfort. The electronically controlled rear-axle locking differential and AWD system have all been improved.

As expected, the high-end behemoth has high-tech gadgets and high-grade comfort. The Mercedes-AMG GLS 63 has three rows of leather-lined seating, a welcoming dashboard design and 64-color ambient trim lighting.

The interior of the 2024 Mercedes-AMG 63 is top-line but there's some difficulty accessing switches on the steering wheel.

The comprehensive standard features have been expanded. It includes adaptive high beam assist, blind-spot assist, Burmester surround sound system, heated and ventilated front seats, panoramic sliding sunroof, wireless smartphone integration and a 360-degree surround-view system.

Seats are upholstered in Nappa leather with handsome color choices: Bahia Brown/Black and Macchiato Beige/Black. The AMG Performance steering wheel with AMG Drive Unit is replete with a burden of buttons, some too close to each other and not easy to access or operate. The steering wheel is heated within the standard equipment parameters. A carbon fiber steering wheel is available.

Beyond luxury, versatility has helped popularize the country’s SUV buying preference. The Mercedes-AMG GLS 63 measures 17.4 cubic feet behind the third row, or up to 42.7 cubic feet behind the second row. With both the second and third rows folded, cargo capacity rises to 84.7 cubic feet.

Big in performance and comfort, the Mercedes-AMG GLS 63 is also big in stature. It’s 206.4 inches long and 84.9 inches wide including side mirrors. The SUV is 70.2 inches tall and has a 123.4-inch wheelbase. It also has a curb weight of more than 6,000 pounds.

A new light signature for the LED taillights highlights the rear presentation and there’s more boldness including quad tailpipes with a slanted square design. The side view is embellished with standard 21-inch alloy wheels with 10 spokes. Optional are 22- and 23-inch wheels ($5,100). A new logo projector shines an AMG-specific light animation on the ground when the front doors are opened.

The AMG maneuvers easily and has an impressively compact turning radius. Still, it’s a big SUV, with some parking situations in tight quarters best avoided.

Second-row captain’s chairs reduce the seating capacity, but it’s a spacious option when hauling a large family isn’t necessary. Only one embellishment for the car’s luxury status is unnecessary. The Mercedes-Benz Air Balance system combines air purification technology with the ability to introduce fragrances directly into the climate control system.

The optional fragrance atomizer allows for personalizing the ambiance of the cabin through the choice of four aromas. It’s positioned in the glovebox. The amount of the scent distributed is adjustable but it’s still strong even in small doses.

Fast, plush, powerful and with comfort to spare, the 2024 Mercedes-AMG GLS63 is an ideal choice. The upscale SUV, with the options, costs slightly less than $164,000. It’s for brand loyalists and new buyers who know what they want and buy the best because they can.
