Mercedes-Benz GLS vs Mercedes-Benz GLB

The 2022 Mercedes-Benz GLB was positioned between the GLA and GLC in the automaker's SUV lineup, available in GLB250 and AMG GLB35 specifications. In Canada, the GLB250 came standard with 4Matic all-wheel drive, while the AMG GLB35 boasted a more powerful drivetrain and sophisticated AWD system. The GLB250 started at $47,000, while the AMG GLB35 began at $59,300, with options pushing the price to approximately $63,500. The GLB's design was unique, with a steep windshield angle and nearly vertical rear window, prioritizing function over form. The interior, however, was a highlight, featuring high-definition displays and ambient lighting, though the controls required some acclimation. Despite its luxury badge, the GLB's road noise and entry-level quality were noticeable.

In contrast, the 2022 Mercedes-Benz GLS offered a more subtle and less flashy look in its base GLS 450 form, avoiding the gaudy grilles of some competitors. The AMG GLS 63 and Maybach versions added visual drama with flared wheel arches, chrome accents, and larger wheels. The GLS's interior, even in its basic form, felt luxurious with leather upholstery, a panoramic roof, and ambient lighting. The digital instrument cluster and infotainment touchscreen were well-integrated, providing a high-quality feel. However, the GLS's suspension lacked the refinement expected in a luxury SUV, with poor body control over bumps and corners. Despite this, the GLS 450's interior was appropriate for a luxury SUV, offering a high-quality experience without being overly fragile.

The 2022 Mercedes-Benz GLB featured a turbocharged 2.0-litre inline-4-cylinder engine, with the AMG GLB35 version producing 302 horsepower and 295 pound-feet of torque. The AMG GLB35 included an AMG SpeedShift eight-speed dual-clutch automatic transmission, AMG Performance variable 4Matic AWD, and an AMG Sport Exhaust system. It accelerated to 100 km/h in 5.2 seconds, with a fuel consumption rating of 11.2 L/100 km. The AMG GLB35 emphasized performance, with a firm ride and responsive handling, especially in Sport+ mode. However, it could be finicky in daily driving situations, with throttle lag and a firm ride.

The 2022 Mercedes-Benz GLS 450 was powered by a 3.0-litre turbocharged inline six-cylinder engine, producing 362 horsepower and 369 pound-feet of torque, with an electric motor adding 21 hp and 184 lb-ft of torque. The GLS 450's engine provided ample power, with the electric assist blending seamlessly. The GLS's air suspension could raise and lower the ride height, but it exhibited poor body control, bouncing over bumps and leaning in corners. The GLS 450 had a towing capacity of 3,500 kilograms, though some competitors offered more. Overall, the GLS 450's performance was adequate, but the suspension lacked the refinement expected in a luxury SUV.

The 2022 Mercedes-Benz GLB offered a relatively roomy interior for a small SUV, with an optional third-row seat suitable for children. Standard features included dual-zone automatic climate control, an eight-way power-adjustable driver's seat, and simulated leather upholstery. The GLB's cargo area provided 560 litres of space, expanding to 1,755 litres with the second-row seat folded. However, the optional third-row seat reduced storage space and was not ideal for North American needs.

The 2022 Mercedes-Benz GLS came standard with a seven-seat configuration, with an optional six-seat version offering captain's chairs. The second-row seats could slide forward and fold for access to the third row, with the GLS offering competitive legroom. Cargo space was 355 litres with all seats in place, expanding to 2,400 litres with the second and third rows folded. The GLS's air suspension could lower for easier loading, but the touchscreen was difficult to reach, and some ergonomic issues were noted.

The 2022 Mercedes-Benz GLB featured the Mercedes Benz User Experience (MBUX) infotainment system, with a 10.25-inch digital gauge cluster and touchscreen. Bluetooth was standard, but Apple CarPlay and Android Auto were optional in Canada. The system could be controlled via voice recognition, touchscreen, touchpad, and steering wheel controls. The "Hey Mercedes" voice prompt worked well, though the navigation system had some quirks.

The 2022 Mercedes-Benz GLS also featured the MBUX infotainment system, with a 12.3-inch touchscreen and digital instrument cluster. Apple CarPlay/Android Auto connectivity, navigation, and a 13-speaker Burmester audio system were included. The voice recognition system was effective, but the touchpad controller was cumbersome. The GLS's navigation system had some issues, suggesting inefficient routes.

The 2022 Mercedes-Benz GLB lacked the optional Driver Assistance Package, which included adaptive cruise control and lane-centring assistance. Standard safety features included Active Brake Assist and blind-spot monitoring. Crash-test ratings were unavailable.
