What We Like

Outstanding engines; sumptuous interior with all the toys; adult-friendly third row; excellent highway manners; real off-road capability with optional equipment

What We Don't

Massive size isn't for everyone; some expected luxuries (such as keyless entry/ignition) cost extra.

Overview

What's New in the 2018 Mercedes-Benz GLS 450?

There's a new design of 19-inch alloy wheel available. And that's about it. But there was a major revamp the year before. See the 2018 Mercedes-Benz GLS-Class models for sale near you

Which GLS 450 is the Best?

As glorious as the V8 versions are, the GLS 450's turbocharged V6 has enough muscle for most people. Which leaves some money left over to stock up on more safety features.

Most of the GLS 550's extra standard features can be added to the GLS 450 as options.

The 2018 Mercedes-AMG GLS 63 ($126,295) goes all out with the 5.5-liter V8, plus an AMG body kit, a roll-resistant suspension system (called the Active Curve System), performance brakes, a sport exhaust, a panoramic sunroof, illuminated running boards, a sport steering wheel, sport front seats and various exclusive AMG interior flourishes.

An optional Driver Assistance package brings adaptive cruise control with steering pilot, blind spot monitoring and active lane-keeping assist.

Safety

Is the 2018 Mercedes-Benz GLS 450 a Safe Car?

The GLS-Class comes with standard stability control, crosswind assist, 4-wheel antilock disc brakes and seven airbags (front, front side, driver's knee and full-length side-curtain), as well as driver alertness monitoring and a rearview camera.

Available driver aids include a surround-view camera system, adaptive cruise control with automatic emergency braking and pedestrian detection, a self-parking system, active blind spot monitoring with rear cross-traffic assist, lane-keeping assistance and active brake assist with a cross-traffic function.

Neither the National Highway Traffic Safety Administration (NHTSA) nor the Insurance Institute for Highway Safety (IIHS) have crash-tested the current GLS-Class, but it should fare extremely well in a collision.

Competition

2018 Mercedes-Benz GLS 450 vs the competition

2018 Cadillac Escalade -- Relatively affordable and comes with a plush, well-appointed cabin.

2018 Infiniti QX80 -- Based on the capable Nissan Patrol SUV produced for overseas markets, the QX80 is a legitimate off-roader with a luxurious interior and a distinctive (possibly controversial) exterior. Updated for 2018.

2018 Land Rover Range Rover -- Not as large or as lumbering to drive. Gorgeous interior. No third-row seating, however.

2018 Lexus LX 570 -- Old under the skin, but luxurious, spacious, capable and built to a lofty standard. Seats up to eight.

Used Mercedes-Benz E 63 AMG Wagon -- The GLS-Class sits at the top of the SUV pyramid, so anyone looking for a used alternative might be intrigued by a certified pre-owned (CPO) example of the world's wildest station wagon. The E 63's track-ready handling is a stark contrast to the GLS, and its practical interior offers much of an SUV's functionality.
