Why it stands out

The 2020 Mercedes-Benz GLB stands out in the crowded luxury SUV market by offering a remarkable blend of space, technology, and functionality. Positioned between the GLA and GLC, it presents an affordable entry into the Mercedes line-up while not compromising on quality or features. With a powerful 2.0-liter turbocharged engine that delivers 221 horsepower, the GLB provides lively performance and an engaging driving experience. Its interior is spacious and practical, accommodating up to seven passengers when equipped with the optional third-row seating—a rarity in this segment. While the GLB excels in driver-focused technology with its dual 10.25-inch infotainment displays and impressive safety features, some owners note a rough ride and concerns over interior material quality. Nevertheless, it remains an excellent option for those prioritizing comfort and advanced features in a compact luxury SUV.
