Why it stands out
The 2021 Mercedes-Benz GLB distinguishes itself in the luxury SUV market with its versatile and spacious interior, highlighted by the option for an additional third row of seats that increases its capacity to seven. This feature, combined with its approachable starting price, makes the GLB an attractive choice for families wanting to join the Mercedes-Benz brand without a hefty price tag. While the GLB is powered by a robust turbocharged 2.0-liter engine that delivers 221 horsepower, its performance, though not class-leading, is adequate for daily family duties. The design is sleek and modern, with a carefully crafted interior that echoes Mercedes-Benz's commitment to luxury and quality. However, some limitations include a cramped third row and a potentially irritating transmission, which are points to consider for prospective buyers.
