Our Take

from the Cars.com expert editorial team

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.

New for 2018

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

Warranty FAQs

What is a Bumper-to-Bumper warranty?

Often called a basic warranty or new-vehicle warranty, a bumper-to-bumper policy covers components like air conditioning, audio systems, vehicle sensors, fuel systems and major electrical components. Most policies exclude regular maintenance like fluid top offs and oil changes, but a few brands have separate free-maintenance provisions, and those that do offer them is slowly rising. Bumper-to-bumper warranties typically expire faster than powertrain warranties.

What is a Powertrain warranty?

Don't be misled a 10-year or 100,000-mile powertrain warranty doesn't promise a decade of free repairs for your car. It typically covers just the engine and transmission, along with any other moving parts that lead to the wheels, like the driveshaft and constant velocity joints. Some automakers also bundle seat belts and airbags into their powertrain warranties. With a few exceptions, powertrain warranties don't cover regular maintenance like engine tuneups and tire rotations.

What is included in Roadside Assistance?

Some automakers include roadside assistance with their bumper-to-bumper or powertrain warranties, while others have separate policies. These programs cover anything from flat-tire changes and locksmith services to jump-starts and towing. Few reimburse incidental costs like motel rooms (if you have to wait for repairs).

What other services could be included in a warranty?

Some automakers include free scheduled maintenance for items such as oil changes, air filters and tire rotations. Some include consumables including brake pads and windshield wipers; others do not. They are typically for the first couple of years of ownership of a new car.

What does CPO mean?

A certified pre-owned or CPO car has been inspected to meet minimum quality standards and typically includes some type of warranty. While dealers and third parties certify cars, the gold standard is an automaker-certified vehicle that provides a factory-backed warranty, often extending the original coverage. Vehicles must be in excellent condition and have low miles and wear to be certified, which is why off-lease vehicles feed many CPO programs.
