2021 Mercedes-Benz GLB vs 2021 Lexus NX Hybrid

The 2021 Mercedes-Benz GLB, introduced in 2020, was a fresh addition to the Mercedes-Benz SUV lineup, fitting between the GLA and GLC in both size and name. Measuring 182.4 inches in length with a 111.4-inch wheelbase, it offered a distinctive yet familiar Mercedes design. Its athletic stance was enhanced by a 7.9-inch ground clearance, making it more versatile for varied terrains. Inside, the GLB impressed with a modern aesthetic, featuring round shapes across the dash and polished metal details in the HVAC vents. The single panel housing the virtual instrument cluster and infotainment screen added elegance, while the cabin's fit and finish met the high standards expected from Mercedes-Benz.

The 2021 Lexus NX Hybrid, positioned between the UX and RX, maintained its sharp-edged, streamlined profile. Despite its sporty appearance, the NX's design had become familiar over the years. Built on the previous-generation Toyota RAV4 platform, it lagged behind in engineering advancements. The F Sport Black Line model featured a larger mesh grille, dark-finish 18-inch wheels, and a striking Grecian Water blue paint. Inside, the NX's design, once radical, felt dated. The stepped center console and lack of wood trim aimed for a sporty feel, but material quality leaned more towards mainstream than luxury.

The 2021 Mercedes-Benz GLB was powered by a turbocharged 2.0-liter inline four-cylinder engine, delivering 221 horsepower and 258 pound-feet of torque. Paired with an eight-speed dual-clutch automatic transmission, it offered front-wheel drive as standard, with optional 4MATIC all-wheel drive. Fuel economy was rated at 23 mpg city and 30 mpg highway for FWD, and 23 mpg city and 31 mpg highway for AWD. Weighing between 3,638 and 3,891 pounds, the GLB accelerated from 0-60 mph in 6.9 seconds, with a top speed of 130 mph. The 4MATIC version enhanced handling and included the Off-Road Engineering Package for better off-road capability.

The 2021 Lexus NX Hybrid combined a 2.5-liter four-cylinder engine with an electric motor, producing a total of 194 horsepower. Standard all-wheel drive provided traction, but performance was modest, with a 0-60 mph time of 9.1 seconds and a top speed of 112 mph. The hybrid system prioritized fuel efficiency over excitement, with a clunky transition between electric and gasoline power. The Black Line package's sport-tuned suspension improved handling, but steering remained numb. Drive modes offered minimal impact on performance, with Eco mode further reducing acceleration.

The 2021 Mercedes-Benz GLB offered a choice between two and three-row configurations. The second row featured adjustable seatbacks and a sliding function, while the third row was retractable. Cargo space varied from 27.0 cubic feet in the two-row model to 5.1 cubic feet behind the third row in the three-row version. The front seats were highly adjustable and comfortable, with available heated and ventilated options. The second row accommodated two adults comfortably, though the third row was best for children.

The 2021 Lexus NX Hybrid had limited headroom and rear legroom, making the rear seats feel cramped. The front seats, however, provided excellent support with 10-way power adjustment. The sloping roofline and thick rear pillars hindered visibility, though large mirrors helped. Cargo space was limited to 16.8 cubic feet with the rear seats up and 53.7 cubic feet with them folded. A power-folding second row and power liftgate were available but not standard.

The 2021 Mercedes-Benz GLB featured the MBUX infotainment system with voice control and keyword activation. Standard equipment included a 7-inch digital instrument cluster and touchscreen, with options to upgrade to 10.25 inches. Smartphone integration, keyless start, and a power liftgate were standard. The Premium Package added advanced features like a Burmester Surround Sound System and augmented reality navigation.

The 2021 Lexus NX Hybrid's infotainment system was a weak point, with an 8-inch display and a difficult-to-use Remote Touch Interface touchpad. Apple CarPlay and Android Auto were available, but the system felt dated. An eight-speaker audio system was standard, with a 14-speaker Mark Levinson system available on higher trims. The base audio system lacked the quality expected from a luxury brand.

The 2021 Mercedes-Benz GLB included standard safety features like active brake assist and attention assist. Optional features included adaptive cruise control and active lane-keeping assist. The Pre-Safe system prepared the cabin for collisions, while Pre-Safe Sound protected hearing. The GLB had not been rated by NHTSA or IIHS.

The 2021 Lexus NX Hybrid received a “Top Safety Pick+” from IIHS and a five-star overall rating from NHTSA. Standard safety features included forward-collision warning, adaptive cruise control, and lane-departure warning. Blind-spot monitoring and rear cross-traffic alert were newly standard. The NX offered a comprehensive safety package, though it lacked a 360-degree camera system.
