2021 Mercedes-Benz GLS-Class Review

by the Edmunds Experts

4/29/2021

What's new

New AMG GLS 63 model
Minor revisions to standard feature content
Part of the third GLS generation introduced for 2020

What is it?

The 2021 Mercedes-Benz GLS is Mercedes' large three-row luxury SUV. Mercedes redesigned it last year, and it's earned a top spot in our rankings because of its high levels of luxury, refinement and technology. Now Mercedes is expanding the GLS lineup with the performance-focused AMG GLS 63 S.

How much power and performance does it get?

The AMG GLS comes in one flavor (for now), and that's the GLS 63. Like the more sedate 483-horsepower GLS 580 SUV, the 63 uses a twin-turbocharged V8 that also features a small 48-volt electric motor attached to the crankshaft.

This isn't a hybrid — there's no separate battery pack that can power the car alone. Rather the GLS uses a mild hybrid assist (Mercedes calls it "EQ Boost") that not only aids engine starting but also delivers a jolt of low-speed power when needed. The result is a rather absurd 603 horsepower and 627 lb-ft of torque put to the pavement through a nine-speed transmission and standard all-wheel-drive system. Other typical AMG touches also abound, such as a performance-oriented adaptive air suspension with advanced body-roll control.

Why does it matter?

Sure, there are plenty of luxury three-row SUVs out there. But few of them make 600 hp. The GLS offers a real, comfortable space for six or seven adults, making it ideal for growing families or driving partners at the firm out to lunch. Adding the AMG 63 trim just means that there's no ceiling to the expectations Mercedes buyers have of their SUVs … or how much they're willing to pay.

What does it compete with?

The GLS 63 has the lock on high-powered three-row SUVs. But there are a few close contenders. The Land Rover Range Rover Sport SVR cranks out up to 575 hp, but its third row is pretty small. The Tesla Model X has a roomy, adult-friendly third row and produces very quick acceleration from its all-electric powertrain, but it lacks the everyday versatility of most competitors.

There's also the oft-rumored but unconfirmed BMW X7 M, which could also easily adapt its twin-turbo V8 to seismic levels of power. Buyers simply looking for a blindingly fast SUV that can seat four or five passengers have several to choose from, including the Jaguar F-Pace SVR, the Porsche Cayenne Turbo or even the Lamborghini Urus.

How does it drive?

Behind the wheel of the AMG GLS 63 S, it's a bit of a tale of two SUVs. On one hand, it can be a pleasantly accessible and easy-to-drive SUV. In its default Comfort drive mode, there's little hint of the performance potential or raw theater that comes with 603 horsepower. Flick the drive mode switch to engage the Sport mode and the 63 S' character changes abruptly.

The engine goes from sounding like a typical V6 to a high-performance V8, which is precisely what you'd expect from AMG. The suspension stiffens slightly to enable more athletic cornering and the throttle response sharpens. We won't say the GLS 63 S drives like a sports car, but it definitely deserves a bold "S" for SUV.

Mercedes says it'll reach 60 mph in a scant 4.1 seconds, which is ridiculously quick for a large three-row SUV. Handling is equally impressive, with body roll managed by the Active Ride Control suspension system that allows the GLS to corner much flatter. Even better, in the stiffest suspension setting, the ride quality remains composed and comfortable. It's not quite as smooth as the base GLS, but considering the gains in handling, it's a minor sacrifice.

We have but a few complaints with the 2021 AMG GLS 63 S. The transmission occasionally makes some uncharacteristically rough gear changes, and the lane-keeping assist system is far too sensitive and heavy-handed in its steering corrections when it tries to keep you in your lane. Thankfully, you can disable the lane-keeping system if you want.

What's the interior like?

The standard GLS interior is attractively designed and smartly engineered. The AMG GLS 63 S' cabin is essentially the same, though you do get an AMG steering wheel, premium Nappa leather, and sport front seats that have larger side bolsters to keep you in place when carving through turns.

One notable option is the Executive Rear Seat package that adds multicontour massaging second-row seats that are heated and ventilated. You also get a large center console between those seats that features a 7-inch MBUX infotainment display and a wireless charging pad.

Other options include a head-up display, enhanced navigation system functionality (it creates augmented reality directions on a front live-video camera image shown on one of the GLS' display screens), a premium Burmester surround-sound system, and various other aesthetic and comfort items.

How practical is it?

In terms of transporting up to seven passengers, the GLS excels. It can even comfortably fit taller adults in the third-row seats. If you want to transport a lot of cargo, the GLS provides 84.7 cubic feet of capacity when you fold the second- and third-row seats down. That's more than what you get from Mercedes' GLE and about the same as from BMW's big X7 SUV.

Hauling both people and cargo is trickier. Luggage space behind the third rows is limited to a paltry 17.4 cubic feet, which means you probably won't have enough space for seven people and their stuff. If that's a regular occurrence for you, you might want to consider upsizing to an even larger SUV such as the Lincoln Navigator or new Cadillac Escalade.

Edmunds says

The 2021 Mercedes-AMG GLS 63 combines the luxury, refinement and cutting-edge technology of the GLS class with rowdy German muscle. It promises performance, utility, a usable third row, and even off-road ability in a package with astonishing power.

2020 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)

The ride is absolutely stunning and the interior is downright beautiful. We love the tech and features... kids can’t get enough of the ambient lighting options. But there’s a catch. The build quality just plain sucks. We’re had the car for 2ish months, and it’s already spent 9 days in the shop. First, the high fan made a crazy loud noise. Then the rain sensing wipers didn’t sense rain. …

Hey Mercedes!

2020 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)

I just bought this SUV so I am just learning all it can do. The coolest thing about it is the voice-activated commands. I’ve had earlier voice-activated interfaces but they didn’t work that well. This one works. If you have an Apple you’re familiar with Siri. Here you say “Hey Mercedes”. The voice says how can I help you? You say navigate to (wherever) and the navigation routes … you to (wherever). You say turn on heated seats, the car turns on the heated seats. You say call (someone in your contacts), the call calls that person. Etc, Etc. Very Cool. Six month update: I still love the car. It gets great gas mileage for a big SUV. One odd thing I could do without is when the Nav route is programmed and you come to a turn, the dash shows the view in front of the car. So the dash shows the same thing as looking through the window. It’s kinda annoying and utterly unnecessary. Just came back from a coast to coast road trip in my GLS. I still like the car, but here a a few shortcomings: Nav system wanted to route us off the interstate and through the city to put us back on the interstate?? We ended up just ignoring the nav system and continuing on the interstate. This happened multiple times. Adaptive cruise control was very aggravating. On posted 70 mph interstates, I set cruise control @ 75 mph to keep with traffic flow. The car would often catch a signal and slow to 70 mph. Additionally, car would slow around curves. Both instances very aggravating as rest of traffic continued at constant speed. Finally, the steering seemed to get squishy, or loose when the cruise control was engaged. Not sure I would get adaptive cruise control again. Positives: very comfortable ride and 26 mpg. Two year update. I still really like the ride and comfort of this vehicle. The biggest annoyance I have is the Navi guidance. It often makes nonsensical routings. I previously mentioned how it would want me to get off the interstate to go thru the city just to get back on. Another example: I wanted to find a Home Depot. It found one < 5 miles ahead on the same street I was on. The Navi wanted me to turn right, jump on the freeway, exit the freeway to put me back on the street I was already on. I ignored the Navi, just went straight down the street. I do this often and let the Navi recalculate the route from my better route. For a system that has ‘learning’ capabilities, it’s pretty dumb. Google directions is much better and gives multiple routes to choose from. Update: don’t like how message appears ‘2nd row right & 2nd row left seats not locked’ when you have the 2nd row seats down. Message appears in place of odometer read out and you have to manually toggle twice (once for each seat) every time the car is started. Update: I've owned the vehicle 4.5 years now. I really enjoy it. I would recommend it to anyone looking for a luxury SUV. I would NOT recommend getting the adaptive cruise control. I was short sighted in not getting the towing package.

GLS580 issue

GLS 580 owner, 12/22/2019

2020 Mercedes-Benz GLS-Class GLS 580 4MATIC 4dr SUV AWD (4.0L 8cyl Turbo gas/electric mild hybrid 9A)

Our new GLS580 with just 108 miles is back at dealer with severe heat issue in center console. So hot, we were worried about fire. Very disappointed that it is now laid up till issue is found and resolved. Driving it was great, but short lived for now sadly. Update - false alarm, it turns out second row system was set at factory on high heat and the second row vents were closed so …

Jay Poocha, 03/23/2021

2021 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A)

Over the years, we have owned many Luxury SUVS and a few mini-vans. We purchased a 2021 GLS 450 in early November 2020. As of today, we have driven 25,402 miles! That's not a typo. In a very short period of time, we have discovered the strengths and weaknesses of the GLS. The strengths: 1. Overall comfort, especially the front seats, is awesome. 2. The added massaging seats is a nice … option (get it, you won't be disappointed on long trips). 3. The ride is smooth on the highway and around town; however, I prefer to use the individualized setting option for the sports suspension on the highway to firm up the ride, otherwise it can be a tad floaty. I prefer a stiffer, more controlled ride. 4. Passing is done with ease at speed; however the 450 holds gears a bit long when rapidly accelerating. It eventually finds its place after a brief struggle. Not bad, but not perfect. After driving 25K in a very short period of time, I would like MB to strongly consider improving a few areas in the cabin: 1. The cell phone ports (only usb c type) must be better placed. They are extremely difficult to plug cords into, plus need some type of ambient lighting to see at night. The wireless charging pad is a pain in the rear to use with a case on a telephone. The space is extremely tight. This must be corrected at some point. The power outlet in the second row is horribly placed. In fact, MB get a F- for its placement, and another F for the amount of space allocated for any charging bases larger than standard size. Just the worst of anything we have ever owned. Outside of these minor issues, my wife wishes MB would add a place for cellphones besides the cupholders or wireless charger area. This is an obvious deign oversight. Second row comfort in the captain's chairs is good, but I would strongly considering getting it with the bench in the future for the center armrest. Although the captain's seats are comfortable, again MB needs to add more places for storage. The third row works for smaller adults and children. We occasionally use it, it works for the occasional trip when are children are traveling with us. The real trick is placement of luggage; three suitcases and a duffle is tight - this requires folding one of the third row seats flat. Although not ideal, it works. For ultimate convenience, I would suggest either a Cadillac ESV or, bite my tongue - a fully loaded Chrysler Pacifica. Having owned both these other vehicles, I can say luggage space is rarely an issue. This leads me to my final thoughts on the GLS, I really like it a lot, its almost perfect except for the few issues I outlined. If MB can address the charging issues, phone placement issues and tweak the trans on shifting on the middle range when accelerating, it is hands down a superior SUV for long trips, daily comfort and drivability around town. It feels rock sold on the highway and does extremely well in rain. If you desire luxury, a very solid feeling ride, solid handling and decent MPG (I'm averaging about 23 MPG) I highly recommend the GLS.

We have a limited number of reviews for the 2021 Mercedes-Benz GLS-Class, so we've included reviews for other years of the GLS-Class since its last redesign.
