2018 Mercedes-Benz GLS

2018 Mercedes-Benz GLS-Class driving through the city

The flagship of the Mercedes-Benz SUV line, the GLS has a traditional SUV look and offers premium comfort and performance for buyers who are looking for a luxury option in the full-size SUV segment.

What is the Mercedes-Benz GLS?

As part of the new Mercedes-Benz naming structure, the Mercedes-Benz GL became the GLS last year. Although it wasn't an entirely new model, the GLS did benefit from a new front end and some features that created an air of reinvention to fit with a new name.

Why Buy the Mercedes-Benz GLS?

Although this flagship SUV of the Mercedes-Benz range shares the same unibody architecture as the GLE, it certainly doesn't share the same exterior styling. Although nowhere near as boxy and retro as the G-Wagon, the GLS looks more like a traditional truck-based SUV than a modern crossover. Apart from the new nose, the 17-foot body of the GLS is largely unchanged since it was launched new in 2013, but it's certainly not dated by any means. This new version is more rugged than the smaller GLE, but it's equally as stylish and contemporary in perhaps a more angular way. You'll have just three different models to choose between in the GLS. The entry point to the lineup now it starts with the GLS 450 and then goes to the GLS 550 before the range tops off in some considerable style and power with the sensational AMG® GLS 63. Each of the three models comes with its own specific powertrain, although all-wheel drive is standard with all three.

What's the Interior of the GLS Like?

All three rows of seating in the GLS are more than suitable for adults, and the level of comfort is off the scale. The front seats are powered and have heating options. As an option, those front seats can also be cooled and equipped with adjustable bolsters and four massage modes, which include the slightly intimidating "fast and vigorous" mode. The second row can also be power-adjustable and heated, and three adults can sit across the second-row without too much fuss. The cabin is quiet and composed, and despite the tall and somewhat boxy shape, you won't hear much wind noise either.

How does the Mercedes GLS Perform?

The GLS lineup now kicks off with a gas 3.0-liter bi-turbo with 362 horsepower in the GLS 450, and a 4.7-liter bi-turbo V-8 with 449 horsepower in the GLS 550. For some very serious full-size luxury SUV performance, the AMG® GLS 63 packs a real punch with a handcrafted 5.5-liter bi-turbo V-8 under the hood that boasts 577 horsepower and propels the GLE to 60 mph in just 4.5 seconds. Having said that, even the gas V-6 gets you there in 6.5 seconds, and the 4.7-liter V8 manages it in just 5.2 seconds.
