The Mercedes-Benz GLB-Class occupies a unique position in the German marque’s extensive SUV lineup. Sitting neatly between the GLA and GLC, it offers a compelling blend of compact dimensions and surprising practicality. For those seeking a premium badge without sacrificing everyday usability, the GLB presents a strong case. While it might be Mercedes’ second smallest and second most affordable SUV, it punches above its weight in key areas, offering technology and features often found in more expensive models. Let’s delve into a comprehensive Mercedes Glb Review to see if it lives up to the hype.
Mercedes GLB: More Versatile Than You Might Think
Often categorized as a subcompact SUV, the Mercedes GLB defies easy classification. While its exterior dimensions are comparable to rivals like the Audi Q3 and BMW X1, the interior space is more akin to a true compact SUV. Think of it as offering the best of both worlds: city-friendly manoeuvrability with the interior volume you need for family life or weekend adventures.
One of the GLB’s standout features is the availability of a third row, transforming it into a seven-seater. This is a rarity in the small SUV segment and adds a layer of versatility that few competitors can match. While the third row is best suited for children or occasional use, it’s a valuable option for growing families or those who occasionally need to carry extra passengers. However, it’s worth noting that when deployed, the third row significantly reduces cargo space.
The Mercedes GLB range offers a variety of models to suit different needs and preferences. The core models are the GLB 250 and GLB 250 4Matic, the latter featuring all-wheel drive for enhanced traction and stability. For driving enthusiasts, the AMG GLB 35 delivers a significant performance boost. It’s important to note that the electric EQB, while sharing a similar platform, is reviewed separately due to its distinct powertrain and characteristics.
Mercedes GLB vs the Competition
The small luxury SUV market is fiercely competitive, with a plethora of excellent options vying for your attention. While the Mercedes GLB is a strong contender, it’s essential to consider its rivals. The BMW X1 and Volvo XC40 are often cross-shopped with the GLB, each offering its own unique blend of style, performance, and features.
For those seeking a larger vehicle, the Genesis GV70 and the Mercedes GLC (the GLB’s larger sibling) are excellent compact luxury SUV alternatives. The recently redesigned BMW X3 (2025 model) should also be on your radar if your budget allows. Ultimately, the best choice depends on your individual priorities, but understanding the competitive landscape is crucial when making an informed decision.

Mercedes GLB Performance Analysis: 8/10
In performance terms, the Mercedes GLB 250 proves to be surprisingly sprightly. Edmunds testing recorded a 0-60 mph time of 6.5 seconds, placing it at the top end of its class. While not overtly sporty in its standard guise, the GLB offers more than adequate power for everyday driving and motorway cruising. The engine response is generally smooth, although there can be a slight delay when abruptly accelerating. However, for typical SUV driving scenarios, the GLB 250 delivers confident and capable performance.
The GLB’s braking system is noteworthy for its ease of modulation and impressive stopping power, providing reassurance in both normal and emergency braking situations. Handling is sure-footed and planted, inspiring confidence when navigating corners and bends. While the GLB 250 isn’t designed to be a thrilling sports SUV, it offers a composed and competent driving experience that will satisfy most owners. For those seeking more excitement, the AMG GLB 35 is the obvious choice.
Mercedes GLB Comfort Assessment: 8.5/10
Comfort is a key strength of the Mercedes GLB. The ride quality is remarkably smooth, effectively absorbing bumps and imperfections in the road surface. The front seats are exceptionally comfortable, providing ample support for long journeys. The cabin is well-insulated from road and wind noise, creating a serene and relaxing environment, even at motorway speeds or on rougher road surfaces. The climate control system is also highly effective, maintaining a comfortable temperature in both hot and cold weather conditions.
Mercedes GLB Interior Review: 8.5/10
The interior of the Mercedes GLB exudes a sense of premium quality and thoughtful design. The elevated ride height and wide door openings make ingress and egress effortless. Once inside, the cabin feels spacious and airy, thanks in part to the GLB’s boxy silhouette. The controls are logically laid out and intuitive to use, minimizing driver distraction. Visibility is excellent in all directions, aided by the large windows. A minor drawback is the somewhat small sun visors, which could offer more comprehensive sun coverage.
Mercedes GLB Technology Features: 8.5/10
The Mercedes GLB excels in the technology department, featuring the acclaimed MBUX infotainment system. This system is widely regarded as one of the best in the industry, offering multiple control methods including touchscreen, voice commands, and touch-sensitive controls. Apple CarPlay and Android Auto are standard, ensuring seamless smartphone integration. While voice commands may occasionally require a moment to process, they are generally accurate and responsive.
The GLB’s driver assistance features are also highly impressive. Adaptive cruise control works effectively in both heavy traffic and open road scenarios. Lane keeping assist, while occasionally assertive, provides valuable lane guidance. Overall, the GLB’s technology suite enhances both convenience and safety.
Mercedes GLB Storage Capacity: 8/10
The GLB’s boxy design truly pays dividends when it comes to storage. The cargo area is surprisingly spacious and accommodating, easily swallowing bulky items. The low load floor and standard power tailgate further enhance practicality. Interior storage is also well-considered, with generously sized door pockets and a substantial centre console bin. Clever touches like spring-loaded cupholders add to the user-friendliness. For families, the GLB is a practical choice, comfortably accommodating rear-facing child seats, although positioning may require adjusting front seat positions. It’s worth noting that some child seat bases may be slightly challenging to latch onto the GLB’s anchor points.
Mercedes GLB Fuel Economy: 8/10
Fuel efficiency is another positive aspect of the Mercedes GLB. EPA estimates suggest a combined fuel economy of up to 28 mpg (miles per gallon). This is slightly above average for the luxury small SUV class. Real-world driving experiences suggest that achieving the EPA figure is realistic with sensible driving habits.
Mercedes GLB Value Proposition: 7.5/10
The Mercedes GLB occupies a sweet spot in the Mercedes SUV range, bridging the gap between the GLA and GLC in terms of both size and price. It presents a compelling value proposition, especially when considering its blend of space, features, and premium badge appeal. However, it’s important to be mindful of optional extras, as adding numerous options can quickly inflate the price, potentially pushing it into GLC territory. Compared to other extra-small luxury SUVs, the GLB may command a slightly higher price, but this is arguably justified by its superior space, performance, and comfort. While some interior materials may not feel overtly luxurious in certain areas, the overall impression is one of quality and value for money.
Mercedes GLB Wildcard Factor: 8/10
The GLB’s distinctive upright and boxy styling sets it apart from the more curvaceous designs prevalent in the small SUV segment. This more traditional SUV aesthetic is a matter of personal preference, but it certainly gives the GLB a unique and utilitarian appeal. While the GLB 250 isn’t designed to be a performance-focused SUV, it’s far from dull. For those seeking driving thrills, the AMG GLB 35 offers a more engaging and dynamic driving experience.
Edmunds Recommendation: Which Mercedes GLB is Right for You?
