Why it stands out

The 2020 Mercedes-Benz GLB stands out in the crowded small SUV market thanks to its versatility and exceptional interior space, which makes it competitive against larger luxury SUVs like the GLC. With the optional third row of seating, it can accommodate up to seven passengers, a rarity in its class. Those who appreciate a blend of utility and comfort will find the GLB appealing, as it combines a well-thought-out design with advanced tech features, including stunning dual 10.25-inch displays. Moreover, its turbocharged engine provides adequate power for city and highway driving, equating to a fun driving experience. On the downside, the GLB is noted for its less-than-stellar brakes and the potential for costs to escalate significantly with the addition of desirable features. In essence, the GLB offers an enjoyable driving experience paired with the luxury expected from the Mercedes-Benz brand.
