Is the Mercedes-Benz GLB a Good SUV?

Yes, the Mercedes-Benz GLB is a good luxury compact SUV. It offers an exceptionally roomy cabin, fantastic build quality, a refined ride, ample engine power, and above-average fuel economy estimates. However, the GLB does have a few shortcomings. It’s not the most agile vehicle in the class, and some of its infotainment controls are hard to use.

Should I Buy the Mercedes-Benz GLB?

The GLB is a good SUV, but it’s worth looking at some of its rivals as well. The Audi Q5 has an intuitive infotainment interface and more potent engine options than the GLB, and the BMW X3 is a lot more fun to drive. However, these vehicles also cost a fair bit more than the GLB.

If you’re willing to look a little smaller, the Mercedes-Benz GLA exhibits sharper handling, and it’s slightly more affordable than the GLB.

Should I Buy a New or Used Mercedes-Benz GLB?

The 2020 GLB is a brand-new vehicle, so the odds of finding a used model are low.

How Much Does the Mercedes-Benz GLB Cost?

The Mercedes-Benz GLB 250 has a starting MSRP of $36,600, which is one of the most affordable base prices in the luxury compact SUV class, alongside the all-new Lincoln Corsair. The new GLB doesn’t offer high-end Mercedes-AMG models, so its price won’t vary much.

Mercedes-Benz GLB Versus the Competition

Which Is Better: Mercedes-Benz GLB or Mercedes-Benz GLC?

The Mercedes-Benz GLC is a bit better-rounded than the new GLB. It’s available as an SUV and a four-door coupe, and it comes with a lineup of muscular engines, including twin-turbocharged V6s and V8s in the AMG models. There’s even a plug-in-hybrid model. The GLC offers a rich cabin full of high-end materials, but the GLB bests the GLC in cargo room, and it can seat more passengers. It’s more affordable too, retailing for around $5,900 less than the base GLC.

Which Is Better: Mercedes-Benz GLB or Audi Q5?

The Audi Q5 and the Mercedes-Benz GLB are both good luxury compact SUVs, but the Q5 is slightly better. It doesn’t have as much cargo space as the Mercedes, but the Q5 offers more potent engines. This Audi also has sharper handling and more luxurious cabin materials than the Mercedes, as well as an easier-to-use infotainment system. However, you’ll pay more for the Audi. Its starting price is around $6,700 higher than the base GLB.

GLB Interior

How Many People Does the GLB Seat?

The GLB seats five people in its standard configuration, but you can add a third row to bump capacity up to seven. The Land Rover Discovery Sport is the only other vehicle in the class that can seat as many people.

MB-Tex synthetic leather seats with 12-way power-adjustments for the front are included in every model. Heated, ventilated, and multicontour front seats are available, as are front sport seats and a heated steering wheel.

The GLB stands out for its exceptional roominess. It offers plenty of head- and legroom in the first two rows, as well as sliding second-row seats. The available third-row seats are more hospitable for kids than adults.

GLB and Child Car Seats

The GLB has two complete sets of LATCH connectors for the second-row outboard seats. The second-row middle seat also has a single tether anchor. Models with the third row come with an additional two sets of LATCH connectors.

GLB Interior Quality

The GLB has a nice cabin, but it prioritizes build quality over luxury. Fit and finish is top-notch.

GLB Cargo Space

At the time of writing, Mercedes-Benz hasn’t released full cargo dimensions for the GLB, but its maximum capacity is an impressive 62 cubic feet (56.7 cubes in three-row models). That’s more than you’ll get in the Mercedes-Benz GLC.

GLB Infotainment, Bluetooth, and Navigation

The Mercedes-Benz User Experience infotainment system comes standard. It consists of a 7-inch digital instrument gauge cluster, a 7-inch touch screen, a touchpad controller, Apple CarPlay, Android Auto, Bluetooth, HD Radio, voice recognition, and four USB ports.

Available equipment includes navigation, a 10.25-inch touch screen, a 10.25-inch digital gauge cluster, satellite radio, a 12-speaker Burmester stereo, and a wireless device charger.

The input methods for the MBUX system earn mixed reviews. Some critics find the touch screen easy to operate, but they knock the touchpad controller and steering-wheel-mounted controls for not always recognizing inputs. The “Hey, Mercedes” voice controls also don’t work particularly well.

GLB Performance

GLB Engine: Capable

Every GLB features a 2.0-liter turbocharged four-cylinder engine that makes 221 horsepower and 258 pound-feet of torque. It’s mated with an eight-speed dual-clutch automatic transmission.

The turbo-four delivers plenty of power for most driving situations. The GLB accelerates relatively swiftly, and the automatic transmission makes smooth, responsive shifts.

GLB Gas Mileage: Great

The GLB gets an EPA-estimated 23 mpg in the city and 30 mpg on the highway. Models with Mercedes’ 4Matic all-wheel-drive system get 23 mpg in the city and 31 mpg on the highway. Those are great ratings for a luxury compact crossover.

GLB Ride and Handling: Deftly Balanced

This vehicle delivers a comfortable ride without much body lean when cornering. It’s not sporty, but its strong brakes and responsive steering help you feel confident around turns, and its suspension soaks up most road flaws. Front-wheel drive is standard, and all-wheel drive is available.

GLB Off-Road Performance

Despite its rugged appearance and off-road drive settings, this vehicle is built more like a compact car than a sturdy off-roader like the Mercedes-Benz G-Class. The GLB doesn’t have much more ground clearance than a small sedan, though it can handle a dirt trail.

The Final Call

The 2020 GLB is a brand-new Mercedes SUV that makes a strong case in the class with its spacious cabin and plentiful cargo room, as well as its serene ride. The GLB’s engine is robust, and it gets good fuel economy estimates. However, some infotainment controls can be frustrating to use, and several rivals have sharper handling than this Mercedes. Nonetheless, the GLB is worth a look in the luxury compact SUV class.

Don’t just take our word for it. Check out comments from some of the reviews that drive our rankings and analysis.

  • "The 2020 GLB 250 finds a seemingly perfect middle ground between the too-small subcompact crossover class and SUVs such as the GLC. Taking into account that the GLB costs $5,900 less than the GLC, we consider it a best-in-class contender. With an unusual available third row of seats, the GLB is one of the most versatile vehicles in any class." -- Edmunds
  • "The 2020 Mercedes GLB is basically a lux Jeep Renegade. In other words, it’s a compact car with an aura of toughness articulated exclusively by its design, but it’s also very practically proportioned and really quite decent to drive around in." -- Jalopnik
  • "In that way and many others, the 2020 Mercedes GLB is more than just a gateway to the brand. It's a fully-fledged member and one that doesn't constantly remind that you bought one of the cheapest Mercedes. Given the front-drive small-car platform and past experiences with the current GLA, we frankly weren't expecting this to be so. Yet, with its ritzy interior, generous cargo space and refined driving experience, the GLB 250 is the real deal." -- Autoblog
