2021 Mercedes-Benz GLB vs 2020 INFINITI QX80

The 2020 INFINITI QX80 was a flagship SUV in Infiniti’s lineup, known for its substantial size compared to the smaller QX50 and QX60 models. It was available in two trim levels: Luxe and Limited. The QX80's exterior had been refreshed in 2018, giving it a more commanding presence with modern features such as welcome lights, power-folding mirrors with LED turn signals, and adaptive front lighting. The SUV was equipped with LED headlights and taillights, and offered a range of comfort and convenience features, including a power-sliding moonroof and roof rails. Buyers could choose from nine paint options and three interior color schemes, with the Limited model featuring premium materials like matte silver and Ash wood trim. While the cabin was generally upscale with soft-touch materials, some trim pieces fell short compared to competitors, and the infotainment system, though updated, was not as modern as others in its class.

The 2021 Mercedes-Benz GLB, introduced in 2020, was a new addition to Mercedes-Benz's extensive SUV lineup, positioned between the GLA and GLC models. Despite its distinct size, the GLB shared the brand's signature design elements, making it visually cohesive with its siblings. The GLB featured a healthy ground clearance of 7.9 inches, providing a more forgiving ride on uneven surfaces. Inside, the GLB was a modern marvel, with a striking design that included round shapes across the dash and polished metal HVAC vents. The cabin boasted excellent fit and finish, with a single panel housing the virtual instrument cluster and infotainment screen. The steering wheel, with its perforated leather grips, added to the vehicle's premium feel.

The 2020 INFINITI QX80 was powered by a robust 5.6-liter V8 engine, delivering 400 horsepower and 413 pound-feet of torque, paired with a seven-speed automatic transmission. Despite its heavy build, the QX80's powertrain managed the load well, though the transmission was less smooth when downshifting compared to competitors. The SUV's fuel efficiency was a notable drawback, with the RWD model achieving 14 mpg in the city and 20 mpg on the highway, while the 4WD version fared slightly worse. The QX80 offered Normal, Snow, and Mud drive modes, and its off-road capabilities were commendable, especially with the right tires.

The QX80's suspension system provided a relatively smooth ride and maintained stability when towing, with a capacity of 8,500 pounds.

The 2021 Mercedes-Benz GLB came with a single engine option: a turbocharged 2.0-liter inline four-cylinder producing 221 horsepower and 258 pound-feet of torque, paired with an eight-speed dual-clutch automatic transmission. The GLB's performance was decent, with a 0-60 mph time of 6.9 seconds and a top speed of 130 mph. The SUV's fuel economy was more favorable, with the FWD model achieving 23 mpg in the city and 30 mpg on the highway. The optional 4MATIC AWD system enhanced handling and stability, especially in adverse weather conditions. The GLB's suspension system, with its independent setup and 18-inch wheels, provided a comfortable ride, and the Off-Road Engineering Package added features like hill-start assist and downhill speed regulation for improved off-road capability.

The 2020 INFINITI QX80 offered plush seating in the first two rows, though the third row was cramped and best suited for children.

The QX80 provided ample cargo space, with 16.6 cubic feet behind the third row and up to 95.1 cubic feet with the second and third rows folded. A power liftgate was standard, enhancing convenience.

The 2021 Mercedes-Benz GLB offered a choice between two- and three-row configurations, with the third row affecting second-row and cargo space.

The second row was spacious for two adults, and the interior featured modern amenities like door pockets and cupholders.

The 2020 INFINITI QX80 came with an 8-inch upper and a 7-inch lower infotainment touch screen, allowing for split functionality.
