2024 Mercedes-Benz GLS-Class

There are three trim levels offered, the GLS 450, GLS 580, and AMG GLS 63 and base prices for the GLS range from $88,150 to $113,150, a notable increase over the 2023 models although significantly more features are now standard. The Mercedes-AMG GLS 63 starts at $147,000 and the Mercedes-Maybach GLS 600, covered separately, starts at $171,150.

The 2024 GLS 450 gains 13 more horsepower, and while its low RPM plateau provides brisk everyday power, the AMG GLS 63 generates significantly more.

In fact, every aspect of the powertrain starting with the engine has been upgraded for greater performance such as the hand-crafted V8, the AMG-tuned transmission, and the all-wheel-drive system that utilizes an electronically locking rear differential. The GLS 580 adopts a “standard fare” turbocharged V8 with a focus on premium comfort and might serve as an alternative to the Mercedes-Benz S580. It gains nearly 30 horsepower for 2024.

All engines utilize a 48-volt mild-hybrid system capable of providing extended engine-off periods and smooth, quick engine restarts, and assist with acceleration.

Model	Powertrain	Horsepower / Torque	Fuel Economy (EPA Combined)
GLS 450	Inline-6 Turbocharged Mild-Hybrid9AT	375 hp / 369 lb-ft	21 mpg
GLS 580	V8 Turbocharged Mild-Hybrid	510 hp / 538 lb-ft	16 mpg
GLS 63 AMG	V8 Turbocharged Mild-Hybrid	603 hp / 627 lb-ft	16 mpg

The GLS 450 returns an impressive 21 MPG combined, one better than last year, despite the additional power. The GLS 580 power is eye-opening, however, so is the fuel consumption - scoring two points less than the turbocharged V8 Range Rover. All engines require premium gasoline.

2024 Mercedes-Benz GLS Towing Capacity

The Mercedes GLS is rated to tow 7,716 pounds (3,500 kilograms).

The GLS is standard with three rows and can seat six or seven passengers, depending on the second-row configuration. Those seated in the third row will find 34.6 inches of legroom and 50 inches of shoulder room. The GLS is not offered in a longer wheelbase version as is the Cadillac Escalade. The cargo room behind the third row measures 17.4 cubic feet and grows to 42.7 cubic feet and 84.7 cubic feet with the second and third rows folded, respectively.

The 2024 GLS gains blind-spot detection and a surround-view monitor (with a see-through-hood feature for off-roading) as standard equipment joining adaptive cruise control with lane centering and lane change, evasive steering assist, adaptive high beam assist, and parking sensors.

All GLS models feature dual 12.3-inch screens with one serving as the digital gauge cluster and the other as an infotainment touchscreen. The infotainment system is the latest that Mercedes offers and includes Apple CarPlay, Android Auto, SiriusXM, HD Radio, Wi-Fi, and navigation with augmented reality.

The GLS 450 also includes a proper premium sound system with Dolby Atmos, sound personalization, 590 watts, nine channels, and 13 speakers, wireless charging, and four USB-C charging ports. A high-end Burmester 3D sound system with 29 speakers, a 1,160-watt amp, and LED illuminated tweeter speakers is offered for $4,550.
