Mercedes-Benz GLS-Class: Luxury SUV with Advanced Features

Mercedes-Benz GLS-Class: Luxury, Performance, and Spacious Comfort

A Luxury SUV with Space and Power

The 2025 Mercedes-Benz GLS-Class is the perfect choice for those who appreciate the luxury of the S-Class but need more space and higher ground clearance. This three-row SUV offers two powerful engine options: a 375-hp turbocharged inline-six in the GLS450 and a 510-hp twin-turbo V8 in the GLS580. Both engines provide a smooth, effortless driving experience with impressive acceleration. The standard air suspension ensures exceptional ride quality, maintaining control and stability, which is remarkable for a vehicle of this size. Inside, the GLS-Class boasts a modern, spacious cabin with seating for six or seven passengers and generous cargo capacity. Performance enthusiasts may be drawn to the 603-hp AMG GLS63, while those seeking ultra-luxury will appreciate the Maybach GLS600. The GLS competes with top-tier rivals like the BMW X7, Land Rover Range Rover, and Lincoln Navigator.

What’s New for 2025?

For 2025, the GLS-Class introduces several updates, enhancing both technology and luxury:

• Fingerprint scanner for personalized driver profiles.
• New Manufaktur Signature styling options, including four additional paint colors and three new nappa leather interior color schemes.
• Manufaktur Signature Interior package, featuring a stitched leather dashboard, Manufaktur logos, headrest pillows, and plush deep-pile carpets.

Mercedes-Benz GLS-Class: Pricing and Trim Options

The 2025 Mercedes-Benz GLS-Class starts at $90,350 and can go up to $117,750, depending on the trim and additional options.

Mercedes-Benz GLS-Class: Which Model to Choose?

The GLS450 provides ample power and a smooth ride, making it an excellent choice over the more expensive GLS580. Opting for the Exclusive trim adds premium features like massaging front seats, while the Executive Rear Seat package introduces massaging rear seats, a wireless charging pad, a tablet controller for the infotainment system, and upgraded safety features, including side-impact airbags. However, note that leather upholstery is not standard and must be added separately.

Engine, Transmission, and Performance

Mercedes-Benz offers two engine options for the GLS-Class, both featuring mild hybridization:

• GLS450: A turbocharged 3.0-liter inline-six producing 375 hp, delivering a silky-smooth drive.
• GLS580: A twin-turbocharged 4.0-liter V8 generating 510 hp, offering significantly more power.

Despite its size, the GLS-Class handles well on twisty roads, though it prioritizes comfort over sportiness. Every model comes with a standard air suspension, and an optional E-Active Body Control system uses a front-facing camera to detect road imperfections and adjust the suspension accordingly for a smoother ride.

Mercedes-Benz GLS-Class: Acceleration Performance

Fuel Economy and Efficiency

Fuel efficiency in the GLS-Class is reasonable for a luxury SUV, but competitors like the BMW X7 offer better mileage.

In real-world testing, an older GLS450 managed 24 MPG on the highway, slightly outperforming its EPA rating. If fuel economy is a priority, the BMW X7 xDrive40i is a better alternative, achieving 28 MPG in highway tests.

Interior, Comfort, and Cargo Space

Borrowing its dashboard and cockpit layout from the GLE-Class, the GLS-Class offers a modern and luxurious interior.

• Seating Capacity: Standard configuration accommodates seven passengers, but an optional second-row captain’s chairs reduce seating to six for added comfort.
• Passenger Space: The first and second rows offer generous space, while the third row is adult-friendly, unlike some competitors like the BMW X7.
• Cargo Capacity: With all seats in place, the GLS provides ample cargo room, making it a practical luxury SUV.

The 2025 Mercedes-Benz GLS-Class remains a top contender in the full-size luxury SUV segment, offering a refined ride, powerful engine options, and a spacious, high-tech interior. Whether you prioritize comfort, performance, or luxury, the GLS-Class delivers a well-rounded package that stands out among its competitors.

Mercedes-Benz GLS-Class: Infotainment and Connectivity

The Mercedes-Benz GLS-Class comes equipped with two massive 12.3-inch digital displays dominating the dashboard. One screen serves as a customizable gauge cluster for the driver, while the other handles infotainment functions, powered by the intuitive MBUX software with voice-activated assistance. Standard features include Apple CarPlay, Android Auto, built-in navigation, and a Wi-Fi hotspot. Audiophiles will appreciate the standard 13-speaker Burmester Surround Sound system, while an optional 26-speaker Burmester 3D audio system delivers an even more immersive experience.

Advanced Safety and Driver-Assistance Features

The GLS-Class offers a comprehensive suite of driver-assistance technologies, though some advanced features, such as semi-autonomous driving, require additional investment. Key safety features include:

• Standard automated emergency braking with pedestrian detection
• Available lane-departure warning with lane-keeping assist
• Available adaptive cruise control with a semi-autonomous driving mode

Warranty and Maintenance Coverage

The Mercedes-Benz GLS-Class comes with a standard four-year/50,000-mile warranty. However, competitors like the Cadillac Escalade provide two additional years of powertrain coverage, while the Lincoln Navigator offers four years of complimentary scheduled maintenance for Black Label models.
