2021 Mercedes-Benz GLS vs 2022 Mercedes-Benz GLS

The 2021 Mercedes-Benz GLS, part of the third generation introduced in 2020, continued to offer a luxurious and spacious experience for families. Originally known as the GL-Class, the GLS evolved to provide a more refined and comfortable alternative to the G-Class, appealing to those seeking a lavish family SUV. The 2021 model featured softened angles and lines, giving it a sleeker appearance despite its large size. Inside, the GLS boasted a futuristic cabin with a massive digital screen spanning nearly two-thirds of the dash, emphasizing its tech-reliant controls. Available in three trims—GLS 450, GLS 580, and the performance-oriented AMG GLS 63—the 2021 GLS offered a range of standard features, including remote keyless entry, nine USB ports, and a 13-speaker Burmester sound system. Various option packages allowed for further customization, enhancing comfort and luxury.

In contrast, the 2022 Mercedes-Benz GLS maintained a more subtle and less flashy look compared to its competitors. The AMG GLS 63 performance model added visual drama with flared wheel arches and a muscular grille, while the Maybach version featured chrome accents and power running boards. The interior of the 2022 GLS, though basic by GLS standards, still exuded luxury with leather upholstery, a panoramic roof, and ambient lighting. The digital instrument cluster and infotainment touchscreen were well-integrated, framed by an upright dashboard. While the GLS 450's interior felt high-quality, it was perhaps too subdued for some tastes. Overall, the 2022 GLS offered a refined and luxurious experience, albeit with a few ergonomic quirks.

The 2021 Mercedes-Benz GLS offered a range of powerful engine options. The entry-level GLS 450 was equipped with a twin-turbocharged 3.0-litre inline-six engine, producing 362 horsepower and 369 pound-feet of torque. The GLS 580 4MATIC featured a twin-turbocharged 4.0-litre V8, delivering 483 hp and 516 lb-ft. Both models utilized a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel drive system. The AMG GLS 63, with its hand-crafted 4.0-litre twin-turbo V8 engine, generated an impressive 603 hp and 627 lb-ft of torque. This model could accelerate from zero to 100 km/h in just 4.2 seconds, reaching a top speed of 280 km/h. The GLS 63's adaptive air suspension and multiple drive modes provided a dynamic driving experience, allowing for precise handling and a comfortable ride.

In 2022, the GLS 450 continued with its 3.0-litre turbocharged inline-six engine, supported by the Mercedes EQ Boost mild-hybrid system. This setup produced 362 horsepower and 369 pound-feet of torque, with an electric motor adding 21 hp and 184 lb-ft in short bursts. The GLS 580 4MATIC, AMG GLS 63, and Maybach GLS 600 4MATIC, all featuring a 4.0-litre twin-turbo V8, were expected to resume production. The GLS 450's inline-six engine provided ample power, but the suspension lacked the refinement expected in a luxury SUV, resulting in excessive body motion. The GLS 450's towing capacity was 3,500 kilograms, slightly less than some competitors. Overall, the 2022 GLS offered a smooth and powerful driving experience, though it fell short in suspension refinement.

The 2021 Mercedes-Benz GLS provided ample interior space with three rows of seating, accommodating up to seven passengers. The front and second-row seats offered generous headroom and legroom, while the third row was suitable for adults. The GLS boasted 355 litres of cargo space with all seats up, expanding to 1,209 litres with the third row folded, and 2,400 litres with both the second and third rows down. The power-folding third row and numerous storage compartments added to its practicality. Despite its spaciousness, the GLS's cargo capacity was slightly less than some competitors, such as the Cadillac Escalade.

In 2022, the GLS continued to offer a seven-seat configuration, with an optional six-seat version featuring captain's chairs. The second-row seats could slide forward, providing easy access to the third row. The GLS offered 355 litres of cargo space with all seats in place, expanding to 2,400 litres with the second and third rows folded. The power-folding seats and air suspension made loading and unloading cargo convenient. However, the touchscreen was difficult to reach, and some ergonomic issues detracted from the overall experience. Despite these minor drawbacks, the 2022 GLS remained a practical and spacious luxury SUV.

The 2021 Mercedes-Benz GLS featured the MBUX infotainment system, with a large touchscreen and digital instrument panel. The system included Apple CarPlay and Android Auto connectivity, though a USB-C cable was required. The voice-control system, activated by saying "Hey Mercedes," allowed for hands-free operation. The touch-sensitive pads on the steering wheel controlled the infotainment and instrument panel, offering a customizable display. While the system had a learning curve, it provided a comprehensive and user-friendly experience.

In 2022, the GLS continued with the MBUX infotainment system, featuring a 12.3-inch touchscreen and digital instrument cluster. The system included Bluetooth, Apple CarPlay/Android Auto connectivity, and natural-language voice recognition. The voice recognition system was particularly effective, allowing for easy operation without taking eyes off the road. However, the touchpad controller was overly sensitive and difficult to use. The augmented-reality navigation feature was standard, though the embedded navigation system occasionally suggested inefficient routes. Despite these issues, the 2022 GLS offered a technologically advanced and user-friendly experience.

The 2021 Mercedes-Benz GLS came standard with a range of driver-assistance features, including Active Brake Assist, rain-sensing wipers, and automatic high beams. Additional safety features included automatic parking assist, a driver-drowsiness monitor, and crosswind assist. Optional safety tech included lane-change assist, adaptive cruise control, and blind spot monitoring. The GLS was equipped with a full array of airbags, traction control, and a tire-pressure monitoring system.

In 2022, the GLS offered a comprehensive suite of standard safety features, including forward collision warning, automatic emergency braking, and blind-spot monitoring. The Crosswind Assist and Pre Safe systems provided additional protection. However, some advanced driver-assistance features, such as adaptive cruise control and a surround-view camera system, were optional. Crash-test ratings from the IIHS and NHTSA were not available at the time of publication. Despite the extensive list of safety features, some advanced options required additional cost.
