About the Mercedes-Benz GLB

Never before has there been a luxury SUV that balances powerful performance with compact dimensions quite like the Mercedes-Benz GLB. As the newest member of the growing family of Mercedes-Benz SUVs, the GLB offers room for up to 7 passengers thanks to an optional third row seat. The GLB is positioned between the city-sized GLA and its larger GLC SUV sibling within the Mercedes-Benz model lineup. Its bold exterior stands out with an upright front fascia, short front and rear overhangs, and protective cladding surrounding the body panels. Power comes in the form of a powerful and efficient 2.0L turbocharged inline 4-cylinder engine paired to a responsive 8-speed DCT transmission. Cutting-edge driver-assistive safety features, connected technology, and impeccable luxury found inside the interior help showcase how the Mercedes-Benz GLB is expected to cause a stir among compact luxury SUVs.

What the Critics Say

With its upright windshield and high hood, the new GLB looks boxier and more trucklike than either the GLA or GLC, though not as squared-off as the big Mercedes G-Class SUV. Its chassis, related to that of the A-Class sedan, feels stout but is lithe enough to give this compact-crossover SUV carlike agility.” — Kelley Blue Book

The engine’s 221 horsepower is more than adequate. With a pair of adults on board, the GLB 250 doesn’t feel strained getting up to speed when merging with interstate traffic. Give credit to the new eight-speed dual-clutch automatic transmission, which never has a stumble when smoothly picking the proper gear.” — Motor Trend

What’s New for 2021

Following its successful debut last year, the popular Mercedes-Benz GLB is back with only two small revisions. Two features now included as standard across the model range are a 115-volt power outlet and a blind-spot monitoring system for greater confidence behind the wheel. Otherwise, the GLB remains a favorite in the compact luxury SUV segment.

Mercedes-Benz GLB Styling

Bold Style & Performance

Confident, capable, and captivating – the exterior of the Mercedes-Benz GLB demands attention from every angle. Its strong proportions, upright angles, and off-road focused design help emphasize the true SUV character of the GLB. Standard 18-inch alloy wheels give the GLB a confident stance on the road while standard LED headlights provide a tasteful accent to the front fascia. Every GLB comes equipped with a potent yet efficient 2.0L inline-4 engine producing 221 horsepower and 258 lb-ft of torque paired to an advanced 8G DCT (dual clutch transmission). You’ll also have the option to equip your GLB with the confidence of legendary 4MATIC® all-wheel drive for added confidence during harsh weather conditions. Drivers can also use the DYNAMIC SELECT switch to choose between three individual drive modes for a custom-tailored driving experience.

Luxurious Cabin

The GLB is the first compact vehicle from Mercedes-Benz to offer optional third row seating for up to 7 passengers. As you take a seat behind the wheel, you’ll notice the single-piece instrument panel featuring a widescreen cockpit controlled via MBUX (Mercedes-Benz User Experience). This groundbreaking system features brilliant screens and graphics, individualizable depiction, an all-color head-up display, navigation with augmented reality, and learning-capable software. Turbine style aluminum air vents add a muscular yet ergonomic look to the dashboard design. A maximum cargo capacity of up to 62 cubic feet (5-seat configuration) ensures that you’ll have plenty of space to carry all of your gear along for the next adventure.

Mercedes-Benz GLB Safety

Driver-Assistive Safety

Next-generation driver-assistive safety innovations available on the Mercedes-Benz GLB help instill a sense of confidence behind the wheel. Several of these life-saving functions have been adopted from the flagship Mercedes-Benz S-Class. Enhanced camera and radar systems allow the GLB to offer available semi-autonomous driving in certain situations. ATTENTION ASSIST® continuously monitors up to 70 parameters of driving behavior, automatically alerting the driver if signs of fatigue are detected. The optional Surround View System uses cameras in all four directions to provide a live overhead view of your immediate surroundings. Available active LED headlamps feature Active Curve Illumination to help you see through twists and turns on the roadways.
