2020 Mercedes-Benz GLB

About the 2020 Mercedes-Benz GLB

1st generation (X247), first U.S. model year.

Mercedes-Benz positioned the GLB as a compact luxury SUV that puts a premium on usable space and flexible family-friendly packaging without becoming a large vehicle. Its upright shape helps deliver roomy seating and cargo space, while the cabin leans on voice-controlled infotainment and Mercedes styling cues to feel modern. Compared with rivals like the BMW X1 and Audi Q3, the GLB’s biggest distinction is its more SUV-like design and its unusually versatile interior layout for this size class.

The 2020 GLB is a small, upright luxury SUV focused on space and everyday usefulness. Both GLB 250 versions have a 221-hp turbo engine, a sliding and reclining second row, smartphone integration, and a power liftgate; the GLB 250 4MATIC adds all-wheel drive and settings for slippery or rough roads. Some examples also have an optional third row.
