Edmunds' Expert Review

Overall rating

The 2018 GLS-Class is Mercedes-Benz's flagship SUV. It's available with three engines, a twin-turbo V6 (362 horsepower, 369 pound-feet of torque) in the GLS 450; a twin-turbo V8 (449 hp, 516 lb-ft) in the GLS 550; and an even more powerful V8 (577 hp, 561 lb-ft) in the barnstorming GLS 63 AMG variant. The GLS 450 and GLS 550 are equipped with a nine-speed automatic transmission, while the GLS 63 AMG comes with a seven-speed automatic. All GLS models feature Mercedes-Benz's all-wheel-drive system called 4Matic.

Still, outright performance is not what the GLS is about. Rather, the GLS is designed to accommodate passengers and cargo with features such as second-row seats with adjustable recline. And, in a pinch, seats can be stowed and moved for flexible cargo requirements. With optional features, all of this can be done electronically at the touch of a button.

Thanks to its street-oriented suspension, the GLS rides smoothly over the road, giving drivers and passengers one of the most serene experiences in its class. And yet an available body roll control system and sport-oriented suspension can firm up the handling.

Some buyers may hesitate once they see the price, particularly if it's a well-equipped example. And others may find the size and dynamics too big and too soft, respectively. But the GLS is levels above the cutthroat midsize SUV and crossover market, and it dominates in the full-size segment by bringing an S-class to the SUV fight.

Notably, we picked the 2018 Mercedes-Benz GLS-Class as one of Edmunds' Best Luxury SUVs for this year.

Trim levels & features

The 2018 Mercedes-Benz GLS-Class is a seven-passenger, large luxury SUV that's offered in three models. The GLS 450 is the base model that's well equipped but doesn't include many of the higher-end features you might expect in an luxury SUV. The GLS 550, ups the power and includes many features that are optional on the GLS 450. Finally, performance aficionados will be drawn to the ultra-powerful AMG GLS 63. All three feature standard all-wheel drive.

The GLS 450 comes with a turbocharged V6 engine (362 hp, 369 lb-ft), 19-inch alloy wheels, a self-leveling air suspension, power-folding and auto-dimming side mirrors, LED running lights and taillights, roof rails, a power liftgate and Mbrace Connect remote vehicle access (via smartphone app; includes remote start).

Interior highlights include premium vinyl upholstery, heated front seats, a 10-way power driver seat (with four-way power lumbar adjustment), driver-seat memory settings, a power-adjustable leather-wrapped steering wheel, an auto-dimming rearview mirror, genuine wood trim and dual-zone automatic climate control. Technology highlights include the COMAND infotainment interface (with both a control knob and a touchpad), an 8-inch central display, a rearview camera, Bluetooth, a 115-volt household-style power outlet, and a sound system that features HD radio and dual USB ports.

An available Premium package adds keyless entry and ignition, a power front passenger seat with memory settings, lighted door sills and multicolor ambient lighting, a navigation system with real-time traffic, voice controls, Apple CarPlay and satellite radio, as well as lane keeping assist and blind-spot monitoring.

The Lighting package bundles adaptive LED headlights and automatic high beams. The Parking Assist package adds front and rear parking sensors, an automated parallel parking system and a surround-view camera system. Also available are three-zone automatic climate control, ventilated front seats, leather upholstery, a 13-speaker Harman Kardon sound system with a CD/DVD player, an SD card reader, and multicontour front seats that add a massaging feature and adjustable side bolsters and shoulder supports.

The GLS 550 starts with all of the above as standard, but it uses a twin-turbo V8 engine (449 hp, 516 lb-ft). It also adds 21-inch alloy wheels, adaptive suspension dampers, sporty exterior styling cues, soft-close doors and upgraded interior trim (including wood steering-wheel inserts). The optional Night package throws in 21-inch black wheels and gloss-black exterior accents.

Optional items on both the GLS 450 and GLS 550 include a panoramic sunroof, heated second-row seats, diamond-quilted leather upholstery and the Driver Assistance package, which adds adaptive cruise control, lane keeping assist, blind-spot monitoring, and front and rear collision mitigation. Also available is an Off-Road package that includes an upgraded multimode terrain selector, a dual-range transfer case and front underbody protection; on the GLS 450, it also adds the GLS 550's standard adaptive dampers.

The high-performance AMG GLS 63 starts with most of the above and adds an even more powerful turbocharged V8 (577 hp, 561 lb-ft), a sport exhaust, exclusive 21-inch alloy wheels, a sport-tuned suspension, upgraded brakes, adaptive stabilizer bars (the Active Curve System in Mercedes-speak), AMG-specific styling elements inside and out, enhanced bolstering for the front seats, upgraded leather upholstery and a flat-bottom sport steering wheel.

All three GL models can also be outfitted with a trailer hitch, a heated steering wheel, power-sliding second-row seats for improved third-row access, rear side-window sunshades, a rear entertainment system, a Wi-Fi hotspot and a 14-speaker Bang & Olufsen audio system.

Trim tested

Edmunds has not yet driven a recent version of this vehicle, but we have limited experience with its predecessor. The following is our first take on what's significant about it and what you can expect.

Driving

Straight-line performance is admirable, but handling on twisty roads is less refined.

Comfort

The GLS-Class is designed to deliver a luxurious feel and succeeds admirably. Virtually no noise or harshness enters the cabin.

Interior

Our test car was equipped with Mercedes' Designo leather interior that offers Bentley quality at about half the price. Truly terrific.

Utility

With the third row up, there's ample space in the GLS-Class. Thanks to folding second and third rows, the GLS is quite utilitarian.

Technology

The GLS includes a number of standard features, but the good stuff is optional. You'll pay extra for satellite radio, navigation, keyless entry, etc.

Simply amazing. Test drive it and you will know.
Jlo,10/24/2017
Is this a car or a magic carpet? Truly it’s like an escalator that effortlessly lifts you along. We test drove and put a deposit on an Audi Q7. We didn’t want the stigma of a Mercedes and to hear comments from family or neighbors. My wife just wasn’t in love with the idea of the Q7 and neither was I. It was too small and lacked a spare tire. We finally said the heck with it and test drove the Benz. We knew immediately it was the right car for us and cancelled the Q7 order. I drive a Dodge Durango that is built on the same platform as the GLS. There is no comparison, the interior or the Benz is smaller because the body is made with more high-strength steel. This car is a vault and safety is my highest priority. I’m a cheapskate. But I will spend money for safety. Everything about this car is impeccable. The LED headlights amazing. Air suspension amazing, go off road and it raises the car 5 inches. Put it in sport mode and it keeps the car flat on winding roads. My wife is amazed by this car. She feels confident and assured. The only thing I don’t care for is the electronic interface and that is just a matter of reading the manual. I have no other complaints. It was expensive. But it is worth it to protect my family and to reward my wife for putting up with me. Test drive this car before you buy anything else. It is so easy and fun to drive.
Best Road Trip SUV
CW Kearney ,05/22/2018
This big SUV drives so easily and you don’t realize how big it is. Comfort and handling are the best. Safety systems work great. The amount of room for seven is great. With third and second row seats down you have a cavern! Have had it for one year and would not want anything but it on a long trip!
Early days, but love the GLS550
Matt M,05/22/2018
Drives like a quick sedan, super comfortable, great interior and exterior looks. Downside of gas mileage on the 550 and I don’t know about reliability as it’s still early days.
Love my MB 450
Jay Singh,09/15/2018
I absolutely love my GL450. It is the most comfortable vehicle I have driven under a $100,00 price tag. I have had it for 3 years and love it just as much today as the day I drove it off the lot. A few things I would point out. Its very very quite in the cabin. The stereo system is a pleasure to listen to. I like mine full blast and enjoy it. The ride quality is amazing. Very soft but has the UMMPH if you put it in sport mode. Its just a push of a button. I like my soft ride and saves on fuel as well. The climate controls are great and nothing to complain of or say much about but the GPS is a pain in the butt to add destinations and so. So we simply use phone apps for that. Reliability and maintenance. Reliability is great. Not once did it not start or had us stranded on a road. Not once. Maintenance is pricey. The dealer always has a good size bill when ever we go in for maintenance. Its not cheap but I knew that before hand and not complaining about it. My 450 has just about 35,000 miles and we will be trading it in for a 2019. Hopefully 2019 will be just as good if not better.

Should I lease or buy a 2018 Mercedes-Benz GLS-Class?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
