Road Test

Mercedes-Benz’s boxy-looking GLB compact luxury SUV slots between the smaller GLA and larger GLC. It has very good visibility, generous passenger and cargo room, and is easy to get in and out of. In our tests we found it to be quick, nimble, and fuel efficient. By eschewing the heavily-tapered styling found on many of its newer models, Mercedes has built a useful compact luxury SUV—a rare find.

Model History

2027

2027 Redesign Year

The redesigned GLB launches with an electric version and will be joined by a hybrid during 2027. Offered as a five- and seven-seater, this smooth-bodied SUV is incrementally larger than before, gaining slightly in length and width. The 2027 GLB is available in two electric versions: the GLB 250+ with EQ Technology and the GLB 350 4MATIC with EQ Technology. They share an 85-kilowatt-hour lithium-ion battery and 800-volt electric architecture that allows rapid recharging from DC fast chargers. Both the electric and hybrid powertrains are shared with the redesigned 2026 CLA. The new GLB will be available with all-wheel drive. Like some other Mercedes models, the GLB interior features a 'Superscreen' that spans the dash with a 10.25-inch instrument panel, 14-inch center display, and 14-inch front passenger display.

2020-Present

Current Generation

The new for 2020 GLB compact SUV slots between Mercedes' GLA and the GLC. The GLB is boxier than those SUVs, with a square, upright stance. Despite its compact dimensions, the GLB offers an optional, albeit tight, third-row seat. Fortunately, the 2.0-liter turbo four-cylinder powertrain is more responsive than it is in its A-Class and CLA platform mates. It posts a respectable 26 mpg overall in our tests. The GLB feels light on its feet and responsive in corners. The ride is firm, but steady and controlled. The cabin is well finished and quiet. Although the infotainment system is very capable and dazzling in appearance, we found it cumbersome to use. The GLB comes with either front- or all-wheel drive. Forward collision warning and automatic emergency braking with pedestrian detection are standard. For 2021, blind spot warning is standard.
