2027 Mercedes-Benz GLS 450 vs. the Competition: How Does It Compare?

When shoppers want a luxury SUV with three rows, substantial passenger space and the presence of a full-size vehicle, the choices become more limited.

The 2027 Mercedes-Benz GLS 450 4MATIC® sits in one of the most competitive parts of this market, facing established luxury SUVs including the BMW X7, Audi Q7, Range Rover and Cadillac Escalade.

The GLS 450 brings a combination of luxury, technology, performance and practicality to the segment. Its 3.0-liter turbocharged inline-six with mild-hybrid technology produces 375 horsepower and 413 lb-ft of torque, while a nine-speed automatic transmission and 4MATIC® all-wheel drive are standard. Mercedes-Benz also gives the GLS 450 a maximum towing capacity of 7,700 pounds.

But how does the GLS 450 compare with its competitors?

Mercedes-Benz GLS 450 vs. BMW X7

The BMW X7 is probably the most direct competitor to the GLS 450.

The two SUVs share several characteristics: both use turbocharged inline-six engines with 48-volt mild-hybrid systems, both have standard all-wheel drive, and both offer three rows of seating.

For 2027, the BMW X7 xDrive40i produces 375 horsepower and 398 lb-ft of torque. It uses an eight-speed automatic transmission and can accelerate from 0 to 60 mph in a BMW-estimated 5.6 seconds.

The GLS 450 produces the same horsepower but has 15 lb-ft more torque. Mercedes-Benz lists a manufacturer-estimated 0-to-60-mph time of 5.4 seconds.

The two SUVs also take slightly different approaches to passenger and cargo space.

The GLS provides approximately 17.4 cubic feet of cargo space behind the third row, compared with about 12.8 cubic feet for the X7. The BMW, however, offers greater maximum cargo capacity with the rear seating folded.

GLS 450 advantages

• 375 horsepower
• 413 lb-ft of torque
• 9-speed automatic transmission
• 7,700-lb maximum towing capacity
• More cargo space behind the third row
• Mercedes-Benz luxury and technology
• Standard 4MATIC® AWD

BMW X7 advantages

• 375 horsepower
• Slightly better EPA fuel economy
• More maximum cargo capacity
• Sport-oriented driving character
• BMW’s xDrive all-wheel-drive system

Which is better?

The BMW X7 is an excellent choice for drivers who put a high priority on driving dynamics. The GLS 450 makes a particularly strong case for shoppers who want a combination of luxury, passenger space, towing capability and Mercedes-Benz technology.

Mercedes-Benz GLS 450 vs. Audi Q7

The Audi Q7 is another natural comparison, although it occupies a somewhat different position in the segment.

For 2027, Audi has significantly updated the Q7. The new model offers up to 429 horsepower and 442 lb-ft of torque, with Audi quoting a 0-to-60-mph time of 4.8 seconds for the higher-output configuration.

That gives the Q7 a substantial performance advantage on paper over the six-cylinder GLS 450.

But the GLS is a larger vehicle with a different emphasis.

The 2027 GLS 450 measures approximately 205.4 inches long with a 123.4-inch wheelbase. Its standard mild-hybrid inline-six provides 375 horsepower and 413 lb-ft of torque.

The Q7 is particularly attractive to buyers who want Audi’s technology and quattro all-wheel-drive system in a somewhat more manageable luxury SUV.

GLS 450 advantages

• Larger full-size SUV proportions
• 375 hp / 413 lb-ft
• 7,700-lb towing capacity
• Three-row seating
• 4MATIC® AWD
• Mercedes-Benz luxury interior and technology

Audi Q7 advantages

• Up to 429 hp in the new 2027 model
• 442 lb-ft of torque
• Audi quattro AWD
• Strong acceleration
• Updated technology and available Bang & Olufsen 4D audio

Which is better?

The Q7 makes sense for shoppers who want a slightly more performance-oriented luxury SUV with Audi’s latest technology. The GLS 450 is better suited to shoppers who want the size, road presence and substantial capability of a full-size Mercedes-Benz SUV.

Mercedes-Benz GLS 450 vs. Range Rover

The Range Rover occupies a unique position in this segment because of its combination of luxury, design and off-road capability.

Unlike the GLS 450, the Range Rover is available in a much broader range of configurations, including multiple powertrains, wheelbases and seating arrangements.

For many shoppers, the decision comes down to priorities.

The GLS 450 is designed as a highly refined luxury SUV that can handle family transportation, long highway trips and towing while providing the technology and comfort expected from a Mercedes-Benz flagship SUV.

The Range Rover places a greater emphasis on its combination of luxury and all-terrain capability.

GLS 450 advantages

• 375-hp inline-six
• 413 lb-ft of torque
• Standard 4MATIC® AWD
• 7,700-lb towing capacity
• Three-row configuration
• Strong highway-oriented luxury experience
• Extensive Mercedes-Benz technology

Range Rover advantages

• Exceptional off-road capability
• Highly customizable lineup
• Available long-wheelbase configurations
• Distinctive luxury design
• Broad range of powertrains and equipment

Which is better?

If serious off-road capability is one of your priorities, the Range Rover has a clear advantage. If most of your driving consists of commuting, family transportation, highway travel and everyday use in Westchester County, the GLS 450 offers an extremely compelling combination of luxury, comfort and capability.

Mercedes-Benz GLS 450 vs. Cadillac Escalade

The Cadillac Escalade is another important competitor because it offers full-size dimensions, three rows and a distinctly American interpretation of luxury.

The Escalade is larger than the GLS and offers substantial passenger and cargo space. It also offers multiple powertrains, including a V8 and diesel option depending on configuration.

The GLS 450 takes a different approach with its turbocharged inline-six and 48-volt mild-hybrid system.

The Mercedes-Benz also offers a substantial amount of technology without requiring shoppers to move into the highest-performance GLS models.

GLS 450 advantages

• 375-hp turbocharged inline-six
• 413 lb-ft of torque
• Mild-hybrid technology
• 4MATIC® AWD standard
• 7,700-lb towing capacity
• European luxury design
• Highly sophisticated cabin technology

Escalade advantages

• Larger overall footprint
• Exceptional cargo capacity
• Available V8 power
• Available diesel engine
• Three-row passenger space
• Large-format luxury interior

Which is better?

The Escalade is an excellent choice for shoppers who want maximum size, space and American full-size SUV presence. The GLS 450 is a strong alternative for buyers who want a more European interpretation of the luxury SUV, with an emphasis on refinement, technology and driving sophistication.

What Makes the GLS 450 Different?

Specifications only tell part of the story.

The GLS 450’s appeal comes from the way its individual characteristics work together.

1. Full-Size Luxury Without V8 Power

The GLS 450 uses a 3.0-liter turbocharged inline-six rather than a V8.

That may sound like a disadvantage to some shoppers, but the numbers tell a different story.

With 375 horsepower and 413 lb-ft of torque, the GLS 450 provides substantial power for everyday driving, highway merging and passing.

Mercedes-Benz pairs the engine with a nine-speed automatic transmission and 48-volt mild-hybrid technology.

For many drivers, the six-cylinder GLS 450 provides more than enough performance without stepping up to the more powerful GLS 580 or AMG® GLS 63.

2. Standard 4MATIC® All-Wheel Drive

Every GLS 450 comes with 4MATIC® all-wheel drive.

That’s particularly relevant for drivers in Westchester County, where winter weather can mean rain, snow, slush and changing road conditions.

AWD doesn’t eliminate the need for appropriate tires or responsible driving, but it can provide additional traction when conditions become challenging.

3. Three Rows Without Giving Up Luxury

The GLS is designed to carry passengers without feeling like a traditional family hauler.

The 2027 GLS offers approximately 17.4 cubic feet of cargo space behind the third row, 43 cubic feet behind the second row and up to approximately 84.9 cubic feet with the seating folded.

That makes the GLS useful for families who regularly need all three rows but still want meaningful cargo space.

4. Strong Towing Capability

The GLS 450 can tow up to 7,700 pounds when properly equipped.

That gives it enough capability for many recreational uses, including towing certain boats, trailers and other equipment.

As always, actual towing capacity depends on the vehicle’s equipment and configuration, so shoppers should verify the rating for the specific GLS they are considering.

Who Should Consider the GLS 450?

The GLS 450 is particularly well suited to drivers who want:

• Three rows of seating
• A full-size luxury SUV
• Standard all-wheel drive
• Strong six-cylinder performance
• A refined highway driving experience
• Significant towing capability
• Advanced technology
• Mercedes-Benz luxury and design
• A vehicle capable of serving as both a family SUV and a premium long-distance vehicle

It may not be the right choice for everyone.

A BMW X7 may appeal more to someone who prioritizes sportier driving dynamics. An Audi Q7 may be more attractive to someone drawn to Audi’s technology and quattro system. A Range Rover is hard to beat for serious off-road use. And an Escalade makes sense for shoppers who want maximum size and American full-size SUV character.

That’s precisely why driving the vehicles you’re considering is important.

Is the Mercedes-Benz GLS 450 a Good Alternative to the BMW X7 and Other Luxury SUVs?

For shoppers looking at full-size luxury SUVs, the 2027 GLS 450 deserves serious consideration.

Its combination of 375 horsepower, 413 lb-ft of torque, standard 4MATIC® AWD, three-row seating and 7,700 pounds of towing capacity gives it the capability expected from a flagship SUV.

But its biggest strength may be its balance.

The GLS 450 isn’t simply about maximum horsepower or maximum cargo space. It is designed to combine those practical characteristics with the quiet, refined and technology-focused experience expected from a Mercedes-Benz.

For a family in Westchester County, that can make the GLS 450 equally at home on the Taconic State Parkway, commuting into Manhattan, taking the kids to activities around Scarsdale or Chappaqua, or heading out of town for a weekend.
