2021 Mercedes-Benz GLB Class vs. Its Competition

2021 Mercedes-Benz GLB-Class (GLB250)
Martin Padgett Martin Padgett Editorial Director

The Mercedes GLB faces a diverse set of rivals, only two of which match its available third row of seats.

The Land Rover Discovery Sport can be fitted with three rows, but we wouldn’t recommend steerage class for anyone taller than a fifth-grader.

The three-row Mazda CX-9 shoots for the stars with its turbo-4 and suave cabin, though it’s not as polished as its European rivals.

The Jaguar F-Pace and Volvo XC60 are strong contenders that are priced (in the case of the Volvo) and usually discounted (F-Pace) under the like-sized Mercedes GLC.
