Mercedes-Benz GLS: Price, Specs, Features & Pros and Cons
The Mercedes-Benz GLS is a full-size luxury SUV with three rows of seating, a spacious cabin, standard all-wheel drive, and the road presence expected from Mercedes-Benz’s largest conventional SUV. It is designed for families who need adult-friendly space, strong towing capability, and a more luxurious experience than a typical large SUV provides.
The U.S. lineup includes the six-cylinder GLS 450, V8-powered GLS 580, and AMG GLS 63. The GLS 450 is the sensible starting point, while the GLS 580 adds effortless V8 power and the AMG GLS 63 turns the three-row SUV into a high-performance vehicle.
For most buyers, the GLS 450 4MATIC is the strongest all-round choice. It has enough power for a fully loaded family trip, standard air suspension, and a far lower purchase price than the V8 and AMG versions.
WheelPedia Rating: 8.2/10
The Mercedes-Benz GLS earns an 8.2/10 WheelPedia Rating for its roomy three-row cabin, strong performance range, high towing capacity, standard all-wheel drive, and long-distance comfort.
Its main drawbacks are a high entry price, premium-fuel requirement, very large size, costly options, and ownership expenses that rise sharply with V8 and AMG models.

About the Mercedes-Benz GLS
The GLS sits above the Mercedes-Benz GLE in the SUV range. It is the better choice for buyers who need a usable third row, more cargo space, and a more substantial long-distance vehicle.
Its key strength is its cabin layout. The first and second rows are generously sized, and the third row provides more usable space than the occasional-use third row in the GLE. The standard seven-seat layout suits larger families, while optional captain’s chairs make access to the third row simpler and create a more premium second-row experience.
The GLS is not a budget-focused SUV. Even the entry model is expensive, and option packages can add substantially to the final transaction price. It is a better fit for buyers who will make regular use of its space and comfort than for buyers who simply want an imposing luxury SUV.
Price and Trims
These are current U.S. starting MSRPs. Final pricing can change with destination charges, paint, wheel choices, packages, dealer-installed accessories, and local market conditions.
| Trim | Starting MSRP | Powertrain | Drivetrain | 0–60 mph |
| GLS 450 4MATIC SUV | $90,250 | 375-hp 3.0L turbo mild hybrid | AWD | 5.8 sec |
| GLS 580 4MATIC SUV | $116,150 | 510-hp 4.0L twin-turbo V8 mild hybrid | AWD | 4.7 sec |
| Mercedes-AMG GLS 63 SUV | $151,050 | 603-hp 4.0L twin-turbo V8 mild hybrid | AWD | 4.1 sec |
The GLS 450 is the recommendation for most buyers. Its inline-six gives the big SUV adequate power, and it includes the same core three-row space and all-wheel-drive capability as the more expensive versions.
The GLS 580 is the choice for buyers who want smooth V8 power and more standard luxury equipment. The AMG GLS 63 is remarkably quick but makes sense only if performance is a central priority rather than a nice-to-have feature.
Engine, Powertrain, and Performance
Every GLS uses a 9-speed automatic transmission and all-wheel drive. The GLS 450 uses a turbocharged inline-six, while the GLS 580 and AMG GLS 63 use twin-turbocharged V8 engines. All three use mild-hybrid assistance, which supports stop-start operation and low-speed response but does not provide meaningful electric-only driving.
| Model | Powertrain | Horsepower | Torque | Drivetrain |
| GLS 450 | 3.0L turbo inline-six mild hybrid | 375 hp | 369 lb-ft | AWD |
| GLS 580 | 4.0L twin-turbo V8 mild hybrid | 510 hp | 538 lb-ft | AWD |
| AMG GLS 63 | 4.0L twin-turbo V8 mild hybrid | 603 hp | 627 lb-ft | AWD |
The GLS 450 is capable enough for school runs, road trips, and towing. Its six-cylinder engine does not feel as effortless as the V8 in a fully loaded GLS, but it remains the sensible choice for buyers who do not need more performance.
The GLS 580 has a stronger, smoother response and is better suited to buyers who regularly carry passengers, luggage, or a trailer. The AMG GLS 63 is extraordinarily quick for its size and includes performance-oriented suspension, braking, and drivetrain hardware.
0–60 MPH Performance
| Model | Manufacturer-Claimed 0–60 mph Time |
| GLS 450 4MATIC | 5.8 sec |
| GLS 580 4MATIC | 4.7 sec |
| Mercedes-AMG GLS 63 | 4.1 sec |
The GLS 450 is quick enough for everyday use. The GLS 580 provides a clear step up in effortless passing power, while the AMG GLS 63 delivers sports-car-like acceleration in a three-row SUV.
Driving Experience
The GLS is built for comfortable long-distance travel rather than narrow city streets. It feels stable at highway speeds, and its standard AIRMATIC air suspension helps smooth out broken pavement while keeping the body controlled.
Its large footprint and 41.1-foot turning circle require more care in parking lots and garages. The available surround-view camera system and parking assistance are especially useful because the GLS is more than 17 feet long.
The GLS 450 is the calmest, most rational version. The GLS 580 provides stronger acceleration without losing its relaxed character. The AMG GLS 63 has a firmer, more focused setup and immense power, but its larger wheels, tires, and brakes can add to the cost and reduce comfort on poor roads.
Fuel Economy
Mercedes-Benz had not published EPA fuel-economy figures for the current GLS lineup at the time of this update. The GLS is a large, heavy gasoline SUV, and buyers should expect V8 and AMG models to use substantially more fuel than the GLS 450.
All GLS models require premium unleaded gasoline. Include fuel, insurance, tires, scheduled service, and expected resale value in your ownership budget before choosing a V8 or AMG version.
Interior, Comfort, and Technology
The GLS has a spacious, upscale cabin with three usable rows and a high seating position. It is designed for family travel, with generous second-row legroom and more third-row space than many luxury SUVs.
Standard and available features include:
- Dual digital displays with MBUX infotainment
- “Hey, Mercedes” voice assistant
- Wireless Apple CarPlay and Android Auto
- Power front seats with memory
- 64-color ambient interior lighting
- Power liftgate
- Panorama roof
- Five-zone automatic climate control
- Standard 40/20/40-split second-row seating
- Available second-row captain’s chairs
- Available Burmester surround-sound system
- Available head-up display
- Available heated, ventilated, and massaging front seats
- Available heated second-row seats
- Available surround-view camera system
The seven-seat configuration is the better choice for larger families. The six-seat captain’s-chair layout is more comfortable for regular second-row passengers and gives easier access to the third row, but it removes the center second-row seat.
Dimensions, Cargo, and Practicality
| Dimension | Measurement |
| Length | 205.0 in. |
| Width without mirrors | 79.9 in. |
| Width with mirrors | 84.9 in. |
| Height | 71.8 in. |
| Wheelbase | 123.4 in. |
| Front legroom | 40.3 in. |
| Second-row legroom | 41.9 in. |
| Third-row legroom | 34.6 in. |
| Cargo capacity | 17.4–84.7 cu. ft. |
| Seating capacity | 7 standard; 6 optional |
The GLS has a useful third row and a large maximum cargo area, although the 17.4 cubic feet behind all three rows is more suited to grocery bags and carry-on luggage than several large suitcases. Fold the third row to create a much more practical space for road trips.
Buyers who do not need the third row should compare the GLS with the Mercedes-Benz GLE, which is easier to park and starts at a substantially lower price. Buyers looking for an electric Mercedes-Benz three-row SUV should also consider the Mercedes-Benz EQS SUV.
Exterior Design
The GLS has an upright, formal SUV shape, a large grille, and a long wheelbase that gives it a substantial appearance. The GLS 450 rides on 21-inch wheels, while the GLS 580 includes 22-inch AMG wheels. Larger wheels are also available.
AMG GLS 63 models add more aggressive bodywork, AMG-specific wheels, a performance exhaust system, and trim-specific exterior details. The standard Panorama roof adds light to all three rows.
Safety Features and Ratings
Standard and available safety features include:
- Active Brake Assist
- Blind Spot Assist with Exit Warning Assist
- ATTENTION ASSIST driver monitoring
- PRE-SAFE occupant protection system
- Rearview camera
- LED headlamps
- Available adaptive cruise control
- Available Active Steering Assist
- Available Active Lane Keeping Assist
- Available Active Lane Change Assist
- Available surround-view camera system
- Available Active Parking Assist
IIHS does not currently publish a 2026 GLS crash-test rating page. Its online GLS record is for an older generation and should not be used to judge the current model. Buyers should check the latest IIHS and NHTSA records for the exact GLS model before purchase.
Reliability, Warranty, and Ownership
The GLS is a sophisticated full-size luxury SUV with turbocharged engines, mild-hybrid hardware, air suspension, and extensive electronics. It will generally cost more to maintain and repair than a mainstream three-row SUV, especially after the factory warranty ends.
The GLS 450 is the most manageable version to own. The GLS 580 adds V8 fuel use, higher parts costs, and expensive tires. The AMG GLS 63 has the largest ownership burden, with performance tires, brakes, insurance, and specialized components.
| Coverage | Length |
| New Vehicle Limited Warranty | 4 years / 50,000 miles |
| Roadside Assistance | 4 years / 50,000 miles |
| Federal Emissions Warranty | Up to 8 years / 80,000 miles on selected components |
Before buying a used GLS, check service history, tire and brake wear, air-suspension operation, third-row mechanisms, electronics, wheel damage, and open recalls. A Mercedes-Benz Certified Pre-Owned vehicle can make sense if you want coverage beyond the original factory warranty.

Should You Buy the Mercedes-Benz GLS?
Buy the Mercedes-Benz GLS if you want a refined full-size luxury SUV with three rows, real second-row comfort, a usable third row, generous cargo capacity, and strong towing ability.
Choose the GLS 450 if you want the best balance of price, power, and ownership costs. Choose the GLS 580 if smooth V8 performance and added luxury equipment are worth the price increase. Choose the AMG GLS 63 only if high performance is important enough to justify its much higher running costs.
Skip the GLS if you do not need a third row, regularly park in tight spaces, want regular-grade fuel, or prefer lower maintenance costs.

Final Verdict
The Mercedes-Benz GLS is a strong choice for buyers who need a genuinely useful three-row luxury SUV. Its cabin is spacious, its third row is more accommodating than that of many luxury rivals, and its maximum cargo capacity is well suited to family travel.
The GLS 450 is the best fit for most buyers. It has enough power, standard air suspension, all-wheel drive, and the same useful seating layout as the higher trims without their steep purchase and running costs.
The GLS 580 and AMG GLS 63 are appealing for their V8 power, but they are expensive upgrades. If you need a large, refined family SUV and will use its third row regularly, the GLS makes a convincing case.
