Why it stands out

The 2019 Mercedes-Benz GLS stands out as the roomiest vehicle in the Mercedes-Benz lineup, with three rows of seating for six or seven people and up to 94 cubic feet of cargo space. It is positioned as a midsize SUV that blends the comfort and space of the S-Class luxury sedan with some off-road capability, which gives it a distinctive role in the brand’s range. For buyers who want a large luxury SUV that emphasizes passenger room and everyday usability, that combination is the GLS’s main appeal.

For 2019, the GLS450 carried a 3.0-liter twin-turbo V6 with 362 horsepower and 369 lb-ft of torque, while the GLS550 used a 4.7-liter twin-turbo V8 rated at 449 hp and 516 lb-ft of torque. The GLS450’s standard equipment included 19-inch wheels, Airmatic air suspension, a backup camera, forward emergency braking, Attention Assist, dual-zone climate, a sunroof, heated front seats with MB-Tex upholstery, burl walnut trim, power-folding third-row seats, an eight-inch touchscreen, HD Radio, and five years of mbrace Connect apps and remote connectivity. The GLS550 added features such as 21-inch wheels, blind spot assist, lane keeping assist, proximity entry, soft-close doors, three-zone climate, front multicontour seats with cooling, ambient lighting, illuminated running boards, navigation with real-time traffic and SiriusXM, Apple CarPlay, Android Auto, a Logic7 surround sound system by Harman/Kardon, and leather. A Grand Edition package was also new for the GLS450 and GLS550, bringing designo Nappa leather in Porcelain and Espresso Brown with diamond stitching and unique piping, including Nappa leather on the dash.

The 2019 GLS is also appealing because it offers a lot of luxury content in a practical package, but it is not without drawbacks. The available diesel engine was dropped for 2018, and owners have noted poor gas mileage, the lack of updated electronics, and rapid depreciation after 40,000 miles as concerns. Even so, the GLS remains attractive for shoppers who value comfort, premium materials, and a spacious three-row layout over flashier or more modern-feeling alternatives.
