The GLS quickly impresses with its excellent combination of comfort, performance and technology. It takes everything we enjoy about the top-rated GLE SUV and puts it into a larger, more potent package, and it might just be one of the most well-rounded vehicles on sale today.

Pros

Easily seats adults in all three rows
Plenty of helpful technology and safety features
Responsive engines and stable handling give the feel of driving a smaller SUV
Flexible cargo capacity

Cons

Some interior controls and buttons are too small or hard to find

What's new

Panoramic sunroof and metallic paint now standard
Part of the third GLS generation introduced for 2020

Overview

Ask a few people their idea of a Mercedes-Benz SUV and there's a good chance the tall boxy G-Class, or G-wagen, comes up. It's hard to deny the G-wagen's presence in pop and celebrity culture, but ultimately, it's just a well-dressed utility truck. For maximum Mercedes SUV luxury, turn to the 2023 Mercedes-Benz GLS. While the G-Class specializes in off-road capability and social currency, and the Maybach GLS (reviewed elsewhere on Edmunds) takes luxury to extremes, the GLS is all about executive-class comfort and convenience.

Cost to Drive^{Cost to drive estimates for the 2023 Mercedes-Benz GLS-Class GLS 450 4MATIC 4dr SUV AWD (3.0L 6cyl Turbo gas/electric mild hybrid 9A) and comparison vehicles are based on 15,000 miles per year (with a mix of 55% city and 45% highway driving) and energy estimates of $3.71 per gallon for premium unleaded in Virginia.}

With a standard adaptive air suspension and lush cabin, the GLS is a VIP hotel suite on wheels, offering strong V6 and V8 engines capable of moving its quiet mass with authority. Not much changes for the 2023 model, except for a newly standard panoramic sunroof, another in a long list of generous standard features included with the "base" model GLS 450.

There's robust competition among three-row luxury SUVs, including the BMW X7, Infiniti QX80 and the Lexus LX 600. But the GLS also competes for attention with the Cadillac Escalade, GMC Yukon Denali, Jeep Grand Wagoneer and Lincoln Navigator. The recently redesigned Land Rover Range Rover added a third row of seats, making it a top rival as well, although it's priced closer to the AMG GLS version. Check out our test team's Expert Rating to see our evaluation of the GLS' comfort, technology features and more.

edmunds TESTED

Rated for you by America's best test team.

Performance

8.5/10

How does the GLS-Class drive? The raw numbers are frankly astounding and, on paper, suggest a much smaller and far sportier vehicle. Our GLS 450 test vehicle sprinted from 0 to 60 mph in 6.2 seconds, which is more than adequate for a luxury SUV with a base engine. It feels strong too, no matter what situation you're driving in. The engine's mild hybrid system improves both performance and efficiency and makes for super-smooth power delivery. Our biggest complaint: occasional hiccups from the transmission.

Stops from 60 mph came in just 105 feet, one of the best results we've seen from any SUV. That's genuine performance-car territory. Part of that comes courtesy of the no-cost summer tires that our test SUV had, which help provide plenty lateral grip too. The steering is light and makes the GLS easy to maneuver in a parking lot or in traffic.

Comfort

8.5/10

How comfortable is the GLS-Class? Mercedes-Benz nailed it when it comes to on-road comfort. The seats are supportive and hugely adjustable, and optional massagers help keep you comfortable after a few hours behind the wheel. The heated and ventilated seats work well, and the automatic climate control quickly evens out cabin temperatures.

There's little intrusion from the outside world, with just a bit of road noise on rough pavement. The ride quality is excellent with the optional E-Active Body Control suspension. It's smooth and composed, ironing out most road imperfections without floating or wallowing. Large wheels can hurt ride quality in many SUVs, but our test vehicle with optional 21-inch wheels didn't seem fazed.

Interior

9/10

How’s the interior? The GLS' interior is excellent from almost every perspective. The driving position is upright and commanding, but you always feel comfortably ensconced in the GLS. There's plenty of room in all three rows, and 6-foot-plus adults can fit comfortably in the easy-to-access third row. The large windows help all-around visibility and make passengers in the rear feel less claustrophobic.

The controls are all well placed and easy to reach, but there's a lot of them and the small text means you have to take your eyes off the road until you work up the muscle memory. Separating the seat controls between the door and the infotainment system is a bit frustrating too.

Technology

9.5/10

How’s the tech? Mercedes' infotainment system is a marvel and benchmark for the class even if the learning curve is a bit steep. The navigation system in particular is a standout, and the augmented reality overlay and turn-by-turn directions in the instrument cluster and head-up display are compelling reasons to ditch the apps on your phone. That said, both Apple CarPlay and Android Auto are standard. All three rows have USB-C ports, and a standard wireless charging pad sits in front of the cupholders.

The driver aids are equally impressive. The adaptive cruise control is among the best we've tested. In traffic, the system maintains a reasonable gap and can slow the GLS down to a complete stop, then start going again when traffic moves.

Storage

8/10

How’s the storage? With the seats down, the GLS' cargo area offers up to 84.7 cubic feet of cargo area behind the front seats. Space drops to 17.4 cubes with all the rows upright, which isn't enough to haul luggage for every passenger. Space is decent enough for the class, though the GLS trails the cavernous Navigator, which offers up 103.3 cubic feet behind the front seats.

The second and third row seats fold flat and can be dropped with buttons in the hatch. Small-item storage is great, with lots of pockets, bins and cupholders spread throughout the cabin. The GLS 450 is rated to tow 7,700 pounds, which places it ahead of its main rival, the BMW X7. Should towing be a high priority, the Lincoln Navigator is again superior, capable of towing up to 8,700 pounds.

Fuel Economy

8/10

How’s the fuel economy? The EPA puts fuel economy at 20 mpg combined (18 city/23 highway), impressive numbers for a vehicle this big and capable. On our evaluation loop, our test GLS got 21 mpg. The GLS returned 19 mpg over extended driving distances through mixed traffic and loaded with passengers and cargo.

Value

8/10

Is the GLS-Class a good value? The GLS isn't cheap, but nothing at this price point can match its impressive build quality. Options can add up quickly, but the GLS is no worse than other luxury SUVs. No other competitor puts together such a well-appointed package for less money. The four-year/50,000-mile bumper-to-bumper warranty is average for the class.

Wildcard

8.5/10

The GLS delivers everything you expect from a Mercedes-Benz vehicle. It packs a clean, understated design, and it's loaded with the latest and greatest tech. Luxury vehicles shouldn't make you work, and the engine provides smooth, effortless power. It sounds good too, especially at full acceleration. It's easy to drive and just a generally nice place to spend an hour or 10 behind the wheel.

Which GLS-Class does Edmunds recommend?

The GLS 580 and AMG GLS 63 are tempting, but we think the GLS 450 would satisfy most people. It costs substantially less than the higher trims and comes with a powerful and efficient turbocharged six-cylinder engine. Standard all-wheel drive and air suspension deliver refined ride comfort and good performance in a variety of situations. We also like the base model's 20-inch wheels, which contribute to a smooth ride. With the savings, you can add plenty of à la carte extras better tailored to your needs.

4.74 Stars, Almost perfect, but...

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.

No issues first year

MarkG, 11/28/2021

2021 Mercedes-Benz GLS-Class GLS 580 4MATIC 4dr SUV AWD (4.0L 8cyl Turbo gas/electric mild hybrid 9A)

Bought the 580 version fully loaded. Have about 12,000 miles on it, with no real issues. Had to top off coolant, and replenish cabin fragrance. Delivers on interior , versatility and quiet ride. Only nit I would have is ride quality over choppy road. The E-Active body control is suppose to scan road and adjust accordingly. My old GL was as smooth, without the $6,500 option. That said, …

Great Ride Terrible Tech.

O Xi Sav, 08/15/2023

2023 Mercedes-Benz GLS-Class GLS 580 4MATIC 4dr SUV AWD (4.0L 8cyl Turbo gas/electric mild hybrid 9A)

Been driving my GLS for a little over a year now. 20,000 miles My first comment is, wow! Did not think the V6 in my 2018 was lacking until I got the V8 in the 580. Truly impressive acceleration. Just had a GLE for a loaner and yeah, the acceleration is real. The real reason I prefer the GLS is the ride. For a vehicle with nearly 7500 lb GVWR it rides marvelously. The road noise and … engine noise is minimal. I prefer the GLS450 interior to the 580, but the quality is great on both. At highway speeds of 80 mph averaged 23 MPG. MB marginally improved their tech, but it is still significantly lacking given the price point. CRAZY THAT ANDROID AUTO MUST BE WIRED. MY LOANER GLE HAD WIRELESS ANDROID AUTO AND IT WAS GOOD, SHAME MB DOES NOT THINK IT IS NEEDED ON THEIR HIGH END PLATFORM WHY HAVE A WIRELESS CHARGER THEN HAVE TO PLUG IT IN TO USE ANDROID AUTO, IT IS ACTUALLY EMBARRASSING. Touch screens and finally a real use for the mouse pad. When driving the touch screen is a reach, I'm 6'1", and the pad does allow for easy swiping. The learning curve is real, and takes time to find things, but overall it very customizable. Tech start up is painfully slow, sometimes taking close to 30 seconds for the system to boot up. JUST GOT NOTICE THAT I HAVE TO PAY FOR THEIR HALF ASSED APP TO START AND LOCK MY CAR! NOT THAT $15 / MONTH IS A WORRY BUT TO EXTORT ME TO USE AN APP THAT ONLY WORKS OCCASSIONALLY IS RIDICULOUS. HAVING TO PAY TO REMOTE START OR LOCK YOU VEHICLE IS BUSH LEAGUE, THE CAR WAS $100K+. My only complaint on the drive side, and it is enough to tell anyone to take a highway drive before you buy, the lane keeping system is jarring to the point of sickening. If you stay left while passing a vehicle or missing an object in the road it will throw you back into what you were avoiding. You cannot turn off the lane tracking without turning off the warning as well. So, in Germanic fashion, we know better than you, you will use the car the way we say is best, even if you have good reason. If one could keep the warning and drop the harsh lane correction it would be great. The cruise is no longer a speed keeping system, it is an auto drive system. I personally have issue giving control to the machine, and there are times when I would like to drive the car. I was exhausted after my first trip fighting the car and how it liked to drive over how I like to drive. Drive 800 miles over holiday and kept cruise off most of the time because it is actually more work to use the cruise than not. Seems cool at first but if you use cruise a lot I would look carefully at how cruise has changed. One thing that I do find odd is you cannot lift the drivers windshield wiper to clean under it, or wipe things off the blade, without hitting the hood and stopping it. I'm not sure how you would change wiper blades like this. New issue that I found is if you are an aggressive driver, guilty as charged, the collision avoidance system is so sensitive it is almost dangerous. My car stopped me in an opposing lane thinking I was going to crash which almost caused a crash. I hate to turn it off because I can see the value but it it needs refinement. Maybe the car is just smarter than me, and as much as I hate the lane system, the car is a great ride, but don't expect much from the tech.

Spaceship look & comfortable ride, it goes down af

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

Windshield wipers auto does not work, Trying to get into Neutral takes an act of god, easy trunk kick function doesn't work, trunk button you have to hold down & that doesn't guarantee trunk is closed, slowing down breaking is very jerky, map shuts down for days, center mouse pad too sensitive, the safety hatch feature never worked. Been in shop 5 times since December. Cost $97k. Look …
