Why it stands out

The 2021 Mercedes-Benz GLB stands out in the compact luxury SUV class by making room for an optional third row. That flexibility gives it a broader passenger-carrying role than many rivals, and it helps the GLB feel like a practical choice for buyers who want Mercedes-Benz style without giving up everyday usefulness. Its approachable starting price also adds to its appeal, especially for shoppers looking for an entry point into the brand.

Beyond the seating layout, the 2021 GLB is described as an attractive crossover SUV with a flexible interior. It also brings multiple powertrain options and impressive technology, which should widen its appeal for buyers who want both variety and modern features. The tradeoffs are worth noting, though: the third row is cramped, the transmission is irritating, and the seats are uncomfortable.
