2021 Mercedes-Benz GLS vs 2021 Mercedes-Benz G-Class

The 2021 Mercedes-Benz GLS carried forward the legacy of its predecessors with a refined design that masked its substantial size. Originally introduced as the GL-Class, the GLS was intended to replace the G-Class but instead found its niche among luxury family SUVs. Its softened angles and sleek lines gave it a more modern appearance, while the interior boasted a futuristic cabin dominated by a massive digital screen. This screen, spanning nearly two-thirds of the dashboard, highlighted the tech-centric nature of the GLS. Available in three trims—GLS 450, GLS 580, and the performance-oriented AMG GLS 63—the GLS offered a range of standard features, including remote keyless entry, dual-zone climate control, and a premium sound system. Optional packages allowed for further customization, enhancing comfort and convenience.

In contrast, the 2021 Mercedes-Benz G-Class, or G-Wagen, retained its iconic boxy design, a nod to its rugged origins. First introduced in 1979, the G-Class underwent its first major redesign in 2019, yet it maintained its classic two-box silhouette. The G-Class was available in two models: the G550 and the AMG G63, both offering extensive customization options through the G Manufaktur Program. The interior featured a tasteful design with a 12.3-inch widescreen infotainment system and a matching virtual instrument panel. Despite its luxurious appointments, the G-Class remained a capable off-road vehicle, appealing to those who valued both style and substance.

The 2021 Mercedes-Benz GLS offered a range of powerful engines, starting with the GLS 450's twin-turbocharged 3.0-liter inline-six, producing 362 horsepower and 369 pound-feet of torque. The GLS 580 stepped up with a twin-turbocharged 4.0-liter V8, delivering 483 hp and 516 lb-ft. Both models featured a nine-speed automatic transmission and Mercedes' 4MATIC all-wheel-drive system. The AMG GLS 63 took performance to another level with a hand-crafted 4.0-liter twin-turbo V8 engine, generating an impressive 603 hp and 627 lb-ft of torque. This powerhouse could accelerate from zero to 60 mph in just 4.1 seconds, with a top speed of 174 mph. The GLS 63's adaptive air suspension and multiple drive modes allowed for precise handling and a comfortable ride, even on challenging roads.

The 2021 Mercedes-Benz G-Class, particularly the G550, was no slouch in the performance department. It featured a twin-turbocharged 4.0-liter V8 engine, producing 416 horsepower and 450 pound-feet of torque. Paired with a nine-speed automatic transmission and permanent four-wheel drive, the G550 could sprint from zero to 60 mph in 5.6 seconds. The G-Class's off-road prowess was enhanced by its adjustable suspension, three locking differentials, and impressive approach, departure, and breakover angles. For those seeking even more power, the AMG G63 offered a tuned version of the V8, delivering 577 hp and 627 lb-ft of torque, achieving a zero to 60 mph time of 4.5 seconds. Despite its size, the G-Class handled well on various terrains, making it a versatile choice for adventurous drivers.

The 2021 Mercedes-Benz GLS excelled in providing spacious and comfortable accommodations for passengers. With three rows of seating, it offered ample headroom and legroom for first- and second-row occupants. The third row, while not as spacious, could still accommodate full-size adults. The GLS boasted 17.4 cubic feet of cargo space behind the third row, expanding to 42.7 cubic feet with the third row folded, and a total of 87.4 cubic feet with both rear rows down. The interior featured numerous storage compartments, including spacious in-door bins and a center console with butterfly doors.

The 2021 Mercedes-Benz G-Class, while luxurious, also proved to be highly functional.

The G550's body-on-frame construction allowed for a payload capacity of over 1,000 pounds and a towing capacity of 7,700 pounds. The cabin provided ample headroom and legroom, with comfortable seating for both front and rear passengers. Storage options were plentiful, with well-designed compartments throughout the cabin. However, some luxury features, such as ventilated front seats, were only available as part of expensive packages.

The 2021 Mercedes-Benz GLS featured the MBUX infotainment system, which included a massive touch screen and a central trackpad for easy navigation. The system supported Apple CarPlay and Android Auto, though a USB-C cable was required for connectivity. The MBUX system's voice-control feature allowed for complex commands, enhancing convenience for drivers. The digital dash extended to the fully-digital instrument panel, both controlled by touch-sensitive pads on the steering wheel. While there was a learning curve, the technology in the GLS was comprehensive and user-friendly once mastered.

The 2021 Mercedes-Benz G-Class impressed with its twin 12.3-inch HD screens, handling both instrument panel and infotainment duties. These screens were customizable, allowing drivers to tailor the layout, content, and color to their preferences. The infotainment system ran the latest version of Mercedes-Benz's COMAND system, with unique Touch Control buttons on the steering wheel for easy navigation. The G-Class offered a rear-seat entertainment system, multiple USB and 12-volt outlets, and standard WiFi. However, wireless device charging was not available, and some features required additional subscriptions.

The 2021 Mercedes-Benz GLS came equipped with a comprehensive suite of driver-assistance features, including Active Brake Assist, forward-collision avoidance, blind-spot monitoring, and automatic high beams. Additional safety tech included lane-keep assist, adaptive cruise control, and a following-distance indicator.

The 2021 Mercedes-Benz G-Class offered a range of standard safety systems, such as a rearview camera, Pre-Safe, traffic-sign assist, and active lane-keeping assist. The G550's size and weight provided inherent safety advantages, though drivers were reminded of the responsibility that came with operating such a large vehicle. While the G-Class had not been rated by the IIHS or NHTSA, its robust construction and advanced safety features contributed to a sense of security for occupants.
