2023 Mercedes-Benz GLB-Class

The main thing that makes the GLB look so good is its small proportions. The GLB doesn’t look like an over-bloated SUV, because it’s not. It’s firmly positioned in the subcompact class and has the right dimensions.

Compromised Third Row. Mercedes offers quite a few SUVs in its lineup, but the subcompact GLB has an ace up its sleeve – an available third row. For an extra $850, Mercedes will fit a third row into the back of the SUV. The availability of the third row gives the GLB a serious edge over the majority of its rivals, which are strict two-row options.

The issue with the third row is that no adult or teenager would agree to willingly sit back there. Passengers in the back only get 29.1 inches of legroom, which makes the third row suitable for kids alone. Unless you have small kids or plan to keep your chihuahua in the back, we recommend skipping the third row and making more use out of the SUV’s nifty sliding second row.

Another downside to getting the third row is cargo capacity. With the third row in place, the SUV offers just 5.1 cubic feet of cargo space. Fold the third row down and the cargo area opens up to a more usable 27 cubic feet.

Available High-Tech Features. If you’re looking to get a luxury vehicle on a budget, we’ll say that there are better value options out there. The base GLB comes sparsely equipped for the luxury segment. You’re getting features like heated exterior mirrors, a power liftgate, synthetic leather upholstery, LED exterior lighting, rain-sensing windshield wipers, dual-zone climate control, and power-adjustable front seats, but that’s it.

Mercedes offers the GLB with a dizzying number of optional features. Depending on the trim, leather upholstery, heated and ventilated front seats, a wireless charging pad, gesture control, a Burmester audio system, a panoramic sunroof, and a head-up display are optional. There are quite a few packages to explore, too, though the way Mercedes bundles features can be inconvenient.

One of the best things about the GLB is its available infotainment system. The Premium Package trades the SUV’s standard seven-inch screens for 10.25-inch units. It’s a major upgrade with a lot more digital real estate. The screens also help the GLB feel like a true luxury vehicle instead of a budget-friendly one.

Spunky AMG Model. Mercedes offers the GLB with two engines and the engines couldn’t be wider apart from one another. The standard engine is a turbocharged 2.0-liter four-cylinder engine that produces 221 horsepower and 258 pound-feet of torque. For daily driving, the base engine proves to be more than adequate, if a little boring. It helps the SUV get to 60 mph in less than seven seconds and can route power to all four wheels as an option, but it doesn’t really stand out.

The AMG GLB 35 is the clear choice for drivers wanting something a little more exciting. The AMG comes with an upgraded turbo 2.0-liter four-cylinder engine that produces 302 hp and 295 lb-ft of torque. These are large increases over the base engine and result in a 5.2-second sprint to 60 mph.

While we’re fans of the engine in the AMG model, there are a few issues that stop us from recommending it to everyone. For one, it’s nearly $10,000 extra over the base GLB 250 4Matic. The AMG GLB 35 has a stiff ride that helps the SUV feel more enjoyable to drive, but borders on being uncomfortable. The GLB 250 doesn’t suffer from the same issue, as its suspension results in agreeable handling and a comfortable ride.

Final Thoughts. While the third row is the 2023 Mercedes-Benz GLB-Class’ true calling card, the SUV has other strengths that make it a good choice in the class. Its boxy design mimics Mercedes’ most upscale models, it’s available with high-tech features, and it has a comfortable interior. The available third row only has enough space for kids and getting into a premium GLB costs premium money, but these aren’t dealbreakers for a subcompact SUV.

As for competitors, the Volvo XC40 features an upscale design, a practical cabin, and loads of standard safety features, and is available with a mild-hybrid powertrain that makes 247 hp. The recently redesigned BMW X1 is another segment favorite. It has an impressive list of standard features, a roomy interior, and balanced handling.
