Mercedes-Benz GLB

The “B” in GLB could easily stand for “boxy.” Its squared-off shape is a key differentiator between it and its sleeker sibling, the GLA, giving it a distinctive look and also far more room inside – enough, in fact, to make a third row an available option (though it’s suitable mainly for children). Owners of the GLB praise the small Benz for its spacious and high-quality interior, which can be packed with a long list of available high-tech features, as well as its easy maneuverability and excellent outward visibility. On the downside, loading the GLB up with options can drive up its price to the level of higher-end models, including Mercedes’ own GLC.

Mercedes-Benz GLB Model Lineup

The GLB is a compact luxury crossover SUV with room for up to seven passengers when equipped with the optional third row. In Mercedes-Benz’s lineup of sport utility vehicles, it slots between the subcompact GLA and the similarly sized but more upscale GLC. The GLB shares a platform and some components with the German automaker’s A-Class sedan.

Mercedes-Benz offers the GLB in three trims: the base GLB 250, the all-wheel-drive GLB 250 4Matic, and the performance-oriented AMG GLB 35. The 250 and 250 4Matic trims both utilize a 2.0-liter turbocharged four-cylinder engine making 221 horsepower, while the AMG variant gets a 302-hp version of the same mill. An eight-speed dual-clutch automatic transmission handles the shifting duties, and power is routed to all four wheels in the GLB 250 4Matic and the GLB 35, while the base GLB 250 is front-wheel drive.

Standard equipment on the GLB includes LED headlights, a power liftgate, faux leather upholstery (which Mercedes calls MB-Tex), power-adjustable front seats, dual-zone automatic climate control, and a 7.0-inch infotainment display with Apple CarPlay and Android Auto integration. Standard safety tech includes forward collision mitigation and, as of 2021, blind-spot warning. The list of available options is long and includes keyless entry, a hands-free liftgate, leather upholstery, heated and ventilated front seats, a panoramic sunroof, navigation, a wireless device charger, and a 10.3-inch infotainment display (which comes standard on the AMG model). Optional driver aids include adaptive cruise control and lane-keeping assist.

Get the ambient lighting, if you live in a snowy climate don't get the 20in black rims/ summer tires

Mercedes-Benz cars have really fragile windshields. Insurance claims (on windshields) are an endless hassle because they have to go through Safelite. But the real problem is that the windshield will break every three months so any joy you hoped to have will be beaten out of you.

I don't like the remote start feature. Doesn't stay in very long or get my interior to necessary temperature I don't like the leg extender handle sticks out too far. Besides that, love the vehicle

It has a lot of wind/road noise. The safety features will probably get you killed as they trigger in situations where you are already paying attention and thus pull your attention away from a situation you need to pay attention in. Parts of the interior feel REALLY cheap.

This vehicle gives an excellent driving experience, I love the driver's assist package, lighting package and the overall appearance. The sound system is top notch. The size is perfect for a small SUV/Crossover vehicle.

Double check the side view. The metal between driver and rear passenger windows interferes driver's view. Also rear view is not perfect for driver.

Do not buy this car! Though the exterior looks nice and it performs pretty well... it is extremely uncomfortable and the technology rarely works as expected and requires you to use your phone a lot while you drive.
