The Mercedes-Benz GLS-Class
is the largest Mercedes
SUV on the market. But it’s got more going for it than sheer size: it’s also among the most competent, comfortable, and downright awesome SUVs available for purchase right now.
If you’re in the market for a big Mercedes SUV, the GLS 450 should be on your radar. From its striking, broad-shouldered frame to an ultra-luxe, roomy interior, it’s everything you could ask for in a three-row luxury SUV—and with GLS models available from Mercedes’s high-performance and luxury divisions, you’ll have your pick from among the giants.
Here to introduce you to the largest SUV Mercedes makes is Jerry
, the app that upgrades your car insurance
in seconds. Let’s take a closer look at the GLS 450 and its powerful siblings. Meet the biggest Mercedes SUV: the GLS-Class
Standing proud at 5,412 pounds and 205 inches, the Mercedes-Benz GLS 450 4Matic
is a three-row marvel of luxury SUV mastery. If you’re looking for Mercedes’ biggest SUV, this is it. Size isn’t the only thing that matters when it comes to the GLS-Class. Sure, it can seat up to seven in next-level comfort thanks to roomy seats in every row and extra-large windows that maximize the sense of space in the cabin. And, yes, its burly mild hybrid six-cylinder engine is capable of towing up to 7,700 pounds of cargo in addition to whatever you can stow in 84.7 cubic feet of cargo space.
But that’s just the beginning. For the GLS 450’s $78,900 starting price, you’ll get an SUV capable of breaking 60mph in just six seconds, with a competitive 20 mpg combined city/highway EPA fuel economy rating, and outfitted with the absolute best—and we do mean best—in automotive technology.
We’re talking best-in-class driver assistance aids, including adaptive cruise control, active brake assist, and an optional semi-autonomous driving mode. We’re also talking about USB-C ports in every row, standard wireless charging pads, and—of course—standard Apple CarPlay and Android Auto smartphone connectivity.
While the base GLS 450 offers just about everything you could want in a big Mercedes SUV, it has three better (and pricier) selves: the V8-powered GLS 850, the high-performance AMC GLS 63, and the ultra-luxe Maybach GLS 600.
Take a look at the tables below for more detail on key specs for the largest Mercedes SUV.

Dimensions
Want to see the straight measurements for Mercedes’ largest SUV? We’ve got all the dimensions of the 2022 GLS 450 right here—and these measurements largely hold true, with some slight variations, for other GLS-class models.
Engine and performance
A big SUV needs a big engine—and the GLS-Class has plenty to offer. The table below compares the engines available for each of the four GLS-Class SUVs.
Cargo and towing
Owning a big SUV isn’t just about who you can fit inside—it also needs to be able to haul all the cargo that makes your travel exceptional. You’ll find the same cargo capacity in every GLS-Class SUV:
Cargo volume behind first row: 84.7 cubic feet
Cargo volume behind second row: 42.7 cubic feet
Cargo volume behind third row: 17.4 cubic feet
The 17.4 cubes on offer with all seats in use isn’t mind-blowing—you’ll find more suitcase space in mid-size SUVs like the Volkswagen Atlas
and the budget-friendly Kia Telluride
, both of which break 20 cubic feet behind the third row. But with seats that fold flat into the floor and tons of small-object storage integrated throughout the cabin, the cargo capacity of the GLS 450 is more than adequate. When it comes to what you can haul behind your Mercedes SUV, on the other hand, the GLS-Class rises to the challenge. The GLS 450’s six-cylinder engine can tow up to 7,700 pounds with the proper configuration. If you’re looking for a little extra towing capacity, it might be worth looking at the Lincoln Navigator
, which can unlock an extra 1,000 pounds of towing capacity—but for most drivers, the GLS’s 7,700 is more than enough. Mercedes GLS-Class vs. the competition
The GLS-Class might be the biggest SUV Mercedes makes, but how does it compare to other three-row utes in the luxury class? The table below compares the dimensions and other key specs for the GLS-Class and a few of its most direct competitors.
In most areas, the GLS-Class stands up shoulder to shoulder with these other SUV giants—and its smooth-riding mild hybrid engine and optional E-Active Body Control suspension give it an edge in terms of efficiency and ride quality. But for sheer size and might, both the Lincoln Navigator and the Jeep
Grand Wagoneer give it a run for its (considerable) money. | | | | | | | Cargo volume w/seats down | |

RECOMMENDEDThis app is great, but the customer service is even better! Not to mention convenient! My husband and I got the lowest rate (much lower than the rates I was finding online through my own searches), quickly, and pretty much all through text message!
