Big and bold and wearing a front-grille badge the size of a serving platter, the 2024 Mercedes-AMG GLS 63 sport utility vehicle is all about luxury, power and excess. And it’s all presented 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 generates another 21 horsepower from the Integrated Starter Generator, a 48-volt auxiliary on-board motor that operates an electrical system giving a power boost to several systems. Operated via a nine-speed automatic transmission, the mid-hybrid SUV advances quickly and has a top speed of 174 mph, while boasting a towing capacity of 7,700 pounds.
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 comprehensive standard features have been expanded to include adaptive high beam assist, blind-spot assist, a 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 (which is heated) with AMG Drive Unit is replete with a bevy of buttons—some too close to each other and not easy to access or operate. A carbon fiber steering wheel is available.
Beyond luxury, versatility has helped popularize the country’s SUV buying preference. Second-row captain’s chairs reduce the seating capacity, but it’s a spacious option when hauling a large family isn’t necessary. 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 also is 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. The Mercedes-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.
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.
Only one embellishment feels completely 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 positioned in the glove box allows for personalizing the ambiance of the cabin through the choice of four aromas. 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 GLS 63 is an ideal choice. The upscale SUV is for brand loyalists and new buyers who know what they want and buy the best because they can.
