2020 Mercedes-Benz GLB vs 2021 Lexus GX

The 2020 Mercedes-Benz GLB presented a unique aesthetic with its boxy and tall design, distinguishing it from other small Mercedes SUVs. Built on a front-wheel-drive platform with an optional 4Matic all-wheel-drive system, it featured a long, flat hood, upright windshield, and nearly vertical rear liftgate, creating a symmetrical look with equal front and rear overhangs. The GLB prioritized function over form, maximizing interior space within its compact dimensions, complemented by robust roof rails. The test model, painted in Mountain Gray metallic and equipped with the AMG Line design package and 20-inch AMG wheels, added a stylish flair to its practical design.

In contrast, the 2021 Lexus GX retained its decade-old body shell with minor updates, including the signature spindle grille and triple-beam LED headlights. The GX's styling was coherent despite not being originally designed for the spindle grille, offering a tough, aggressive look that appealed to SUV enthusiasts. However, the interior lagged behind modern luxury standards, with wood trim resembling plastic and an abundance of actual plastic. Despite standard leather upholstery, the GX's interior felt outdated, lacking the refinement expected in a contemporary luxury SUV.

The 2020 Mercedes-Benz GLB was powered by a turbocharged 2.0-liter four-cylinder engine, producing 221 horsepower and 258 lb-ft of torque. It accelerated to 60 mph in 6.9 seconds, aided by a wide torque band and an eight-speed dual-clutch automatic transmission. The GLB offered a choice between front-wheel drive and 4Matic AWD, with an Off-Road mode for a 50:50 power split. The test vehicle, equipped with an adaptive damping suspension and 20-inch AMG wheels, provided a soft ride in Comfort mode and a more dynamic experience in Sport mode. Despite its modest engine, the GLB delivered an engaging driving experience, though its brakes faded under enthusiastic driving.

The 2021 Lexus GX featured a 4.6-liter V8 engine with 301 horsepower and 329 lb-ft of torque, paired with a six-speed automatic transmission. It reached 60 mph in 7.8 seconds, but its 5,130-pound weight affected performance at higher speeds. The GX's body-on-frame construction resulted in a less refined ride, with noticeable body roll and low grip in corners. However, it excelled in off-road capability, with a Torsen center differential, low-range 4WD, and various driver aids. The GX offered a towing capacity of 6,500 pounds, but its on-road performance felt outdated compared to modern SUVs.

The 2020 Mercedes-Benz GLB offered impressive interior space, with optional third-row seating, a feature not available in other Mercedes SUVs except the larger GLS. It comfortably accommodated four adults, with ample headroom, tall seating positions, and excellent visibility. The second-row seat was adjustable, enhancing cargo or passenger space as needed. The GLB provided 22 cubic feet of cargo space behind the second row, expanding to 62 cubic feet with the seats folded, thanks to its traditional SUV roofline.

The 2021 Lexus GX's interior reflected its age, with limited legroom due to an upright dashboard and high center console. The steering wheel's odd angle and tall seating position were reminiscent of driving a bus. While visibility was generally good, forward visibility was hindered by the tall hood. The GX offered three rows of seating, but the third row was best suited for children and difficult to access. Cargo space was limited, with only 64.7 cubic feet available with the second and third rows folded, significantly less than competitors like the Land Rover Discovery.

The 2020 Mercedes-Benz GLB's technology was highlighted by the optional Premium Package, featuring twin 10.25-inch displays with lush graphics and fast response. The MBUX infotainment system included Android Auto, Apple CarPlay, and natural voice recognition. The Multimedia Package added navigation with augmented video, while the Parking Assistance Package offered a surround-view camera and semi-autonomous parking. The Burmester premium sound system provided excellent audio quality.

The 2021 Lexus GX was light on tech features, lacking Apple CarPlay and Android Auto. The standard infotainment system had outdated graphics and limited functionality, with a separate display for time and temperature. However, analog controls were available for most functions, offering a straightforward interface. A 17-speaker Mark Levinson audio system was optional, but the overall tech experience felt dated for a luxury SUV.

The 2020 Mercedes-Benz GLB came standard with several safety features, including a driver monitoring system, backup camera, forward collision warning, and automatic emergency braking. The optional Driver Assistance Package added advanced features like adaptive cruise control, lane-centering assistance, and evasive steering assistance. However, crash-test ratings from NHTSA and IIHS were unavailable at the time of review.

The 2021 Lexus GX included the Lexus Safety System+ as standard, with features like forward-collision warning, automatic emergency braking, and adaptive cruise control. Blind-spot monitoring and rear cross-traffic alert were also standard. However, the GX lacked some safety features found in other Lexus and Toyota models, such as traffic-sign recognition and Lane Tracing Assist. Crash-test ratings from NHTSA and IIHS were not available.
