Why it stands out
The 2021 Mercedes-Benz GLB sets itself apart in the luxury compact SUV segment thanks to its versatile seating configurations and high-quality interior. With the availability of an optional third row, the GLB can shift from a standard five-seater to a seven-passenger vehicle, making it an appealing choice for families or those needing extra space. The GLB maintains a strong balance between practicality and luxury, featuring a well-crafted cabin that boasts both advanced technology and upscale materials. It is equipped with the latest Mercedes-Benz User Experience (MBUX) system, which enhances usability with voice control, and integrates seamlessly with smartphones. While the powertrain is limited to a singular engine choice, its turbocharged 2.0-liter inline four-cylinder provides sufficient performance for daily driving, with an engaging eight-speed dual-clutch automatic transmission. Buyers will appreciate the GLB’s strong safety ratings and high-quality finishing touches that reflect the brand's reputation for excellence. Potential downsides include a third row that may feel cramped for adults and the setup of the transmission that some might find less than smooth.
