2018 Mercedes-Benz GLS 550 review: Our expert's take


What it is: The seven-seat GLS-Class SUV has standard all-wheel drive, three rows of seats and three available engines: two turbocharged V-8s and a turbocharged V-6. As with other Mercedes, the top-shelf version of the GLS-Class is a performance-oriented AMG edition, the AMG GLS 63. Competitors include the Audi Q7, Cadillac Escalade, Infiniti QX80 and Lexus LX 570.


Available for the GLS 450 and GLS 550, a new Grand Edition includes diamond-quilted Nappa leather upholstery, a Nappa leather dashboard, open-pore brown ash trim, ambient lighting and brown velour floormats. Exterior Grand Edition cues include special badges and two-tone wheels – 20 inches on the GLS 450 and 21 inches on the GLS 550.

AMG GLS 63
The AMG GLS 63 packs big power into a big SUV: 577 horsepower from a twin-turbocharged 5.5-liter V-8 engine that works with a seven-speed automatic transmission. 

What’s Special

  • All-wheel drive splits 60 percent of the SUV’s power to the rear wheels and 40 percent to the front
  • AMG air suspension
  • AMG sport exhaust system
  • Widened fenders to fit 21-inch wheels

Capable SUV for all conditions

I picked up a 2018 550 and fell in love! By far one of the best vehicles I have ever owned. The big comfortable SUV is responsive both with acceleration and handling. The 3rd row is actually usable unlike others! There are many suspension settings that actually work. I drive from the highway in sport mode, through feet of snow In the mountains in winter to the the class 4 roads of VT in mud season! Never have a problem. If this was the last car I ever own, I would be satisfied!

Safety car ever

This car is a dream car. It is a reliable, comfortable, and safe car. It has many nice features such as seat massage and lane assist.

I expect more from a vehicle of this price

the car has many fine features as it should. Areas that need improvement - smart phone integration, the rear seat headrests are awkward and uncomfortable, all of the side window molding becomes discolored. It's ugly. The most disappointing thing is Mercedes' reaction. In an industry where customer service is usually paramount they just don't seem to care.
