KBB Expert Review

KBB Editors' Overview

By Keith Buglewicz

Since the S-Class is the Mercedes-Benz flagship sedan, it makes sense to re-brand its full-size SUV the 2017 Mercedes-Benz GLS-Class. The "S" is a little superfluous though, as the big Benz SUV is already a well-known leader when it comes to luxury, power and prestige. Whether you choose the eco-friendly diesel-powered GLS350d (delayed release), the pavement-devouring AMG GLS63 and its twin-turbo V8, or one of the models in between, there's little to deter anybody of means from considering this big Benz. The 2017 GLS also gets a new 9-speed automatic transmission (except for the AMG), air suspension, revised exterior styling and an updated interior. It all adds to an already extensive list of standard equipment, and at a price that's surprisingly fair for a prestigious luxury vehicle.

You'll Like This Car If...

If you need to tow 7,500 pounds and want 7-passenger capacity in a luxury SUV that doesn't share its underpinnings with a lower-end brand model -- looking at you, Cadillac Escalade and Lexus LX -- then the Mercedes-Benz GLS-Class is a compelling choice.

You May Not Like This Car If...

The GLS is very accommodating, but competitors offer more towing capability -- like the Escalade, Lincoln Navigator and Infiniti QX80 -- and others offer many of the GLS's features for less money, like the GMC Acadia and Jeep Grand Cherokee.

What's New for 2017

In addition to the new name, the 2017 GLS-Class gets a new 9-speed automatic transmission, available air suspension, a revised exterior and a new interior. Also available are new Designo interior and exterior treatments.

Driving It Driving Impressions

We drove the 2017 Mercedes-Benz GLS-Class in Austria both on and off the pavement. On the snow-blown roads in the Austrian Alps, the 2017 GLS made short work of the slippery conditions, thanks to an extended Dynamic Select transmission, which includes a "slippery" setting. It was so good that driver over-confidence may be an issue. Select the off-road engineering package, and the Dynamic Select gets an Off-Road+ setting that enables a low-range gearbox and center differential lock for off-pavement driving, as long as it's not too demanding. Yet this is still a luxury vehicle, one that surrounds its seven passengers in the kind of leather-bound comfort you'd expect. There's plenty of power from the twin-turbo V8 in the GLS550 4Matic, and we love the new 9-speed automatic transmission. The 577-horsepower V8 in the AMG may be overkill, but it's a ton of fun.

Favorite Features

This is an excellent diesel engine, offering smooth, quiet and clean power in the 2017 GLS350 BlueTEC. It offers more torque than many V8 engines, but still gets very good fuel economy.

There's no getting around the fact that the 2017 Mercedes-Benz GLS-Class is a big SUV, but getting around in a GLS-Class is easier thanks to the available Surround View system, which gives you a 360-degree bird’s-eye view of your surroundings.
