2022 Mercedes-Benz GLB vs 2021 Mercedes-Benz GLS

The 2021 Mercedes-Benz GLS, a continuation of the third generation introduced in 2020, was a luxurious SUV that offered a blend of practicality and opulence. Originally launched as the GL-Class in 2006, it was intended to replace the G-Class but instead found its niche among affluent families seeking a more comfortable alternative to the Navigator and Escalade. The GLS featured a sleek design with softened angles and a futuristic interior dominated by a massive digital screen, emphasizing its tech-reliant nature. Available in three trims—GLS 450, GLS 580, and the high-performance AMG GLS 63—the GLS catered to a range of preferences, offering a host of standard features and optional packages to enhance comfort and style.

In contrast, the 2022 Mercedes-Benz GLB was a compact SUV that slotted between the GLA and GLC in the automaker's lineup. It was available in GLB250 and AMG GLB35 specifications, with the latter offering a more powerful drivetrain and sophisticated AWD system. The GLB's design was functional, with a steep windshield angle and short overhangs, prioritizing practicality over aesthetics. Inside, the GLB boasted a beautifully rendered cabin with high-definition displays and ambient lighting, though its controls required some acclimation. Despite its entry-level status, the GLB offered a range of options to enhance its appearance and functionality, making it a versatile choice for urban dwellers.

The 2021 Mercedes-Benz GLS offered a range of powerful engine options, starting with the GLS 450's 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 AWD 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, achieving 0-100 km/h in just 4.2 seconds. The GLS's adaptive air suspension and multiple drive modes ensured a smooth and agile driving experience, defying its size and weight.

The 2022 Mercedes-Benz GLB, on the other hand, featured a turbocharged 2.0-litre inline-4-cylinder engine across both versions. The AMG GLB35 was enhanced to produce 302 horsepower and 295 pound-feet of torque, significantly outperforming the GLB250. Equipped with an AMG SpeedShift eight-speed dual-clutch automatic transmission and AMG Performance variable 4Matic AWD, the AMG GLB35 accelerated to 100 km/h in 5.2 seconds. While the AMG GLB35 emphasized performance, it sacrificed some daily-driving comfort, with a firm ride and noticeable road noise. However, its nimble handling and responsive powertrain made it a thrilling choice for driving enthusiasts.

The 2021 Mercedes-Benz GLS excelled in providing spacious seating across its three rows, accommodating up to seven passengers. The front and second-row occupants enjoyed ample headroom and legroom, while the third row was suitable for full-size adults. The GLS offered generous cargo space, with 355 litres behind the third row, expanding to 1,209 litres with the third row folded, and a total of 2,400 litres with both rear rows down. The interior featured numerous storage compartments, enhancing its practicality for families.

In contrast, the 2022 Mercedes-Benz GLB catered to urbanites seeking a compact yet roomy SUV. It offered an optional third-row seat for children, though it compromised cargo space. The GLB's standard features included dual-zone climate control and an eight-way power-adjustable driver's seat, with options for leather upholstery and a panoramic sunroof. The GLB provided 560 litres of cargo space behind the second row, expanding to 1,755 litres with the second row folded, making it a versatile choice for city dwellers.

The 2021 Mercedes-Benz GLS featured the advanced MBUX infotainment system, with a massive touch screen and voice-control capabilities. The system included Apple CarPlay and Android Auto connectivity, though it required a USB-C cable. The digital dash extended to the fully digital instrument panel, controlled by touch-sensitive pads on the steering wheel. The MBUX system's voice-control feature allowed for complex commands, enhancing the overall user experience.

The 2022 Mercedes-Benz GLB also utilized the MBUX infotainment system, with a 10.25-inch digital gauge cluster and touchscreen display. While Apple CarPlay and Android Auto were optional in Canada, the system offered natural voice recognition and a digital assistant. The GLB's MBUX technology was user-friendly, with multiple interaction methods, including voice, touchscreen, and steering wheel controls. Despite its high-tech appearance, the system was accessible to those familiar with modern smartphones.

The 2021 Mercedes-Benz GLS came equipped with a comprehensive suite of driver-assistance features, including Active Brake Assist, rain-sensing wipers, and automatic high beams. Additional safety options included lane-change assist, adaptive cruise control, and blind spot monitoring. The GLS also featured a full array of airbags, traction control, and a tire-pressure monitoring system, ensuring a high level of safety for its occupants.

In contrast, the 2022 Mercedes-Benz GLB's test vehicle lacked the optional Driver Assistance Package, which included advanced safety features like adaptive cruise control and lane-centring assistance. However, it did come with standard Active Brake Assist and optional blind-spot monitoring. While the GLB offered some safety features, the absence of the Driver Assistance Package limited its overall safety capabilities.
