The Mercedes-Benz GLS lineup ranges from the six-cylinder GLS 450 to V8-powered luxury and Mercedes-AMG® performance models, with the Mercedes-Maybach GLS 600 serving as a separate ultra-luxury flagship in recent model years. This guide compares the 2022 through 2027 Mercedes-Benz GLS lineup so Hoffman Estates drivers can see which trims were offered, how their engines and output changed, and what separates each configuration.
The refreshed 2027 Mercedes-Benz GLS lineup begins with the GLS 450 4MATIC® SUV and GLS 580 4MATIC® SUV, while the Mercedes-AMG® GLS 63 continues as the high-performance option. Mercedes-Benz has confirmed meaningful powertrain changes for both standard GLS models. The GLS 450 keeps a turbocharged 3.0-liter inline-six with mild hybrid assistance, while the GLS 580 receives a revised 4.0-liter V8 with more horsepower and torque than the previous model.
The GLS 450 produces 375 horsepower and 413 lb-ft of torque for 2027, with additional short-duration assistance available from the integrated starter-generator. The GLS 580 increases output to 530 horsepower and 553 lb-ft of torque, up from 510 horsepower and 538 lb-ft in 2026. The AMG® GLS 63 remains part of the refreshed 2027 range, while complete 2027 U.S. specifications for the Mercedes-Maybach GLS 600 have not yet been published by Mercedes-Benz as of this update.

The 2026 Mercedes-Benz GLS lineup gives buyers four distinct levels of performance and luxury when the Mercedes-Maybach model is included. The GLS 450 4MATIC® SUV serves as the core three-row model with a 375-horsepower turbocharged inline-six. The GLS 580 4MATIC® SUV moves to a 510-horsepower biturbo V8, while the AMG® GLS 63 increases performance significantly with a handcrafted 603-horsepower AMG® V8.
The Mercedes-Maybach GLS 600 sits apart from the regular GLS range as the ultra-luxury choice. Its 4.0-liter biturbo V8 with mild hybrid drive produces 550 horsepower and 568 lb-ft of torque for 2026. Unlike the standard three-row GLS models, the Maybach emphasizes rear-seat comfort with seating for five as standard or an available four-seat configuration with individual executive rear seats.

The 2025 Mercedes-Benz GLS carries forward the lineup established by the 2024 refresh. The GLS 450 4MATIC® SUV uses a 375-horsepower turbocharged inline-six, while the GLS 580 4MATIC® SUV provides a significant step up in effortless acceleration with its 510-horsepower biturbo V8. Drivers seeking more aggressive performance can move into the AMG® GLS 63, which combines 603 horsepower with AMG®-specific suspension, braking, and all-wheel-drive systems.
The Mercedes-Maybach GLS 600 remains the most comfort-focused member of the broader GLS family. Its 550-horsepower biturbo V8 produces 538 lb-ft of torque for the 2025 model year, while the cabin adds Maybach-specific features such as Executive Rear Seating, exclusive Nappa leather options, E-ACTIVE BODY CONTROL, and extensive rear-passenger comfort equipment. That makes the Maybach substantially different from simply choosing a more heavily optioned GLS 580.

The 2024 Mercedes-Benz GLS received a substantial mid-cycle refresh that changed more than its styling. The GLS 450 increased to 375 horsepower and 369 lb-ft of torque, while the GLS 580 moved to 510 horsepower and 538 lb-ft. Both models use mild hybrid technology, and Mercedes-Benz also added updated MBUX technology, a newer steering wheel design, an Off-Road driving mode, and available Transparent Hood functionality.
The AMG® GLS 63 continued as the high-performance three-row model with 603 horsepower, while the refreshed Mercedes-Maybach GLS 600 produced 550 horsepower and 538 lb-ft of torque. The Maybach also received updated paint, upholstery, trim, and cabin technology, while retaining features such as Executive Rear Seating and the available refrigerated rear compartment. For buyers comparing 2023 and 2024 models, this is the key year when the standard GLS 450 and GLS 580 received their current higher-output engines.

The 2023 Mercedes-Benz GLS lineup included four distinct choices when the Mercedes-Maybach model is included: the GLS 450 4MATIC® SUV, GLS 580 4MATIC® SUV, AMG® GLS 63 SUV, and Mercedes-Maybach GLS 600 SUV. This was the final model year before the 2024 refresh increased output for the two core GLS models, so the 2023 GLS 450 and GLS 580 have different horsepower ratings than their 2024 and newer counterparts.
The GLS 450 uses a turbocharged 3.0-liter inline-six with EQ Boost to produce 362 horsepower and 369 lb-ft of torque. The GLS 580 replaces the six-cylinder with a 4.0-liter biturbo V8 rated at 483 horsepower and 516 lb-ft. Above those models, the AMG® GLS 63 delivers 603 horsepower and 627 lb-ft from its handcrafted AMG® V8, while the Mercedes-Maybach GLS 600 combines a 550-horsepower V8 with a cabin designed around rear-passenger comfort and Maybach-specific materials.

The 2022 Mercedes-Benz GLS offered the same basic four-model hierarchy as 2023, but each configuration served a very different buyer. The GLS 450 was the six-cylinder entry point, the GLS 580 added V8 power, the AMG® GLS 63 focused on maximum performance, and the Mercedes-Maybach GLS 600 shifted the emphasis toward chauffeur-level rear-seat comfort. All four used 4MATIC® Performance 4MATIC®+ all-wheel drive.
The GLS 450 produces 362 horsepower and 369 lb-ft of torque from its turbocharged inline-six, while the GLS 580 increases output to 483 horsepower and 516 lb-ft through its biturbo V8. The AMG® GLS 63 raises output to 603 horsepower and adds AMG®-specific chassis, suspension, braking, and all-wheel-drive hardware. The Maybach GLS 600 also uses a V8, but its 550-horsepower powertrain is paired with features such as power rear seats, Maybach-specific Nappa leather, additional sound insulation, and available individual rear seating rather than an AMG® performance setup.

The GLS 450 makes sense for drivers who want the full three-row GLS cabin without moving to a V8. Its turbocharged inline-six offers strong everyday acceleration, standard 4MATIC® all-wheel drive, and the same basic passenger and cargo flexibility as the GLS 580.
The GLS 580 adds substantial V8 power without moving into the more aggressive character of an AMG® model. It is a strong fit for buyers who want quicker acceleration, effortless highway passing power, and a higher level of standard equipment while retaining a conventional GLS three-row layout.
The AMG® GLS 63 combines 603 horsepower in recent models with AMG® Performance 4MATIC® ACTIVE RIDE CONTROL, larger performance brakes, and AMG®-specific drive modes. It is the choice for buyers who want the GLS’s space with substantially more aggressive performance.
The Mercedes-Maybach GLS 600 is not simply the next performance step above the GLS 580. Its priorities are different, with available individual rear seats, power-reclining rear seating, extensive Nappa leather, Maybach-specific trim, and additional rear-passenger amenities.
The names of the core GLS models stayed remarkably consistent from 2022 through 2026, but their specifications did not. The biggest change arrived for 2024, when the refreshed GLS 450 increased from 362 to 375 horsepower and the GLS 580 jumped from 483 to 510 horsepower. Mercedes-Benz also updated the exterior styling, MBUX system, steering wheel, wheel designs, and available off-road technology without changing the basic four-model hierarchy.
Another significant change arrives for 2027. The GLS 580 increases again to 530 horsepower and 553 lb-ft of torque, while the GLS 450 receives 413 lb-ft of rated engine torque. Mercedes-Benz has confirmed the refreshed GLS 450, GLS 580, and AMG® GLS 63, while complete U.S. details for a 2027 Mercedes-Maybach GLS 600 have not yet been published. That distinction matters for buyers comparing model years because it avoids assuming every previous GLS configuration automatically carries into the newest year.
For most Hoffman Estates drivers, the decision starts with how much performance and rear-seat luxury you actually need. The GLS 450 provides the same three-row format with more than enough power for I-90 commuting, airport runs, and family travel. The GLS 580 adds V8 power that is especially noticeable during highway acceleration, towing, and fully loaded trips, while the AMG® GLS 63 is aimed at drivers who actively want performance rather than simply additional horsepower.
The Mercedes-Maybach GLS 600 serves a different purpose altogether. Its two-row-focused luxury layout and available individual rear seats prioritize rear passengers rather than maximum seating capacity. Buyers who regularly need three rows should therefore focus primarily on the GLS 450, GLS 580, or AMG® GLS 63 instead of assuming the Maybach is simply a more expensive version of the same family-oriented GLS layout.
Mercedes-Benz of Hoffman Estates can help you compare current GLS 450, GLS 580, and AMG® GLS 63 models along with available pre-owned GLS and Mercedes-Maybach configurations. Review engine output, seating layouts, comfort features, performance equipment, and model-year differences to find the GLS that fits how you plan to use your SUV.
