What Makes the Mercedes GLB Stand Out?
A Compact SUV with Big Ambitions
The Mercedes GLB is a luxury crossover SUV that slots between the smaller GLA and the larger GLC in Mercedes-Benz’s lineup. Introduced in 2019, the GLB has quickly gained popularity for its boxy, practical design and optional third-row seating, a rarity in the subcompact luxury SUV segment. For 2025, the GLB receives subtle updates, including refreshed styling, enhanced technology, and improved efficiency, making it a compelling choice for families and luxury enthusiasts alike.
Key Highlights of the 2025 Mercedes GLB
- Spacious 7-Seater Option: Accommodates up to seven passengers, ideal for families.
- Premium Interior: High-quality materials and advanced tech elevate the cabin experience.
- Efficient Powertrain: A 48-volt mild-hybrid system boosts performance and fuel economy.
- Versatile Design: Boxy shape maximizes interior space and cargo capacity.
- Advanced Safety: Five-star Euro NCAP rating with cutting-edge driver assistance features.
Design and Styling: Rugged Yet Refined
Exterior Appeal
The 2025 Mercedes GLB retains its distinctive boxy silhouette, drawing inspiration from the iconic G-Class while maintaining a modern, polished look. The updated front fascia features sharper LED headlights, a redesigned bumper, and a prominent chrome grille, giving it a bold and commanding presence. Available in new colors like Spectral Blue Metallic, the GLB offers wheel options ranging from 18 to 20 inches, with the AMG Night Package adding sporty 19- or 20-inch AMG wheels for a more aggressive stance.
The GLB’s compact dimensions (4.63 meters in length) make it easy to maneuver in urban environments, yet its tall profile maximizes interior space. This practicality sets it apart from rivals like the Audi Q3 and BMW X1, which lack the third-row option.
Interior Comfort and Practicality
Step inside the Mercedes GLB, and you’re greeted by a luxurious cabin that feels like a scaled-down version of Mercedes’ higher-end models. The 2025 model features a twin-screen setup with two 10.25-inch displays for the instrument cluster and infotainment system, wrapped in premium materials like Nappa leather and brushed metal accents. The boxy design translates to impressive headroom and legroom, even for second-row passengers.
The optional third row is best suited for children or occasional use, as it reduces boot space significantly. With all seats in use, cargo capacity is limited, but folding the third and second rows unlocks up to 62 cubic feet of storage, rivaling larger SUVs like the BMW X3.
Performance and Driving Experience
Powertrain Options
The 2025 Mercedes GLB offers a range of engines, all paired with automatic transmissions and optional 4MATIC all-wheel drive. The lineup includes:
- GLB 200: A 1.3-liter petrol engine with 161 horsepower, ideal for city driving.
- GLB 200d and 220d: 2.0-liter diesel engines with 148 and 187 horsepower, respectively, offering robust torque for highway cruising.
- GLB 250: A 2.0-liter turbocharged petrol engine producing 221 horsepower and 258 lb-ft of torque, enhanced by a 48-volt mild-hybrid system for an additional 13 horsepower.
- GLB 35 AMG: A high-performance variant with 306 horsepower and a 0-62 mph sprint in just 5.5 seconds.
The mild-hybrid system, introduced in 2024, improves fuel efficiency and provides smoother acceleration. The GLB 250 achieves an EPA-estimated 25 mpg city and 33 mpg highway, making it competitive with rivals like the Volvo XC40 and Lexus NX.
Ride and Handling
The Mercedes GLB strikes a balance between comfort and agility. Its light steering and compact size make it easy to navigate tight spaces, while the suspension smooths out rough roads. The GLB 220d, in particular, offers a refined driving experience with strong low-end torque, making it ideal for long-distance trips. However, the base GLB 200 can feel underpowered when fully loaded, and the AMG 35, while quick, sacrifices some ride comfort for sportiness.
Compared to competitors, the GLB isn’t as engaging to drive as the BMW X1, but it excels in refinement and ease of use, especially in urban settings.
Technology and Infotainment
MBUX Infotainment System
The 2025 Mercedes GLB features the latest Mercedes-Benz User Experience (MBUX) system, a standout in the luxury SUV segment. The voice-activated “Hey Mercedes” assistant responds to natural language commands, allowing you to adjust climate settings, find navigation routes, or even locate nearby coffee shops. Wireless Apple CarPlay and Android Auto are standard, though some users note that these interfaces don’t fully utilize the 10.25-inch screen.
Safety and Driver Assistance
Safety is a strong suit for the 7-seater luxury SUV, with a five-star Euro NCAP rating from 2019. Standard safety features include:
- Active Brake Assist with Cross-Traffic Function
- Active Lane Keeping Assist
- Active Speed Limit Assist
- 360-degree camera (part of the Parking Package)
The adaptive cruise control and lane-centering systems make highway driving effortless, rivaling those found in more expensive Mercedes models.
Practicality: A True Family SUV
Seating and Space
The Mercedes GLB is a game-changer for families seeking a compact yet versatile SUV. The sliding second-row seats offer flexibility, allowing you to prioritize legroom or cargo space. The third row, while cramped for adults, is perfect for kids, making the GLB a practical choice for growing families. ISOFIX points and top tethers ensure easy installation of child seats.
Cargo Capacity
With the third row folded, the GLB offers 500-570 liters of boot space, depending on the model. Folding both rear rows expands this to 62 cubic feet, making it suitable for everything from grocery runs to weekend getaways. The hands-free power liftgate, standard on most trims, adds convenience for busy parents.
What’s New for 2025?
The 2025 Mercedes GLB builds on the 2024 facelift with minor but meaningful updates:
- Refreshed Styling: New LED headlights, taillights, and a redesigned front bumper.
- Enhanced MBUX: Improved voice recognition and updated software for a smoother user experience.
- New Color Options: Spectral Blue Metallic joins the palette.
- Standard Features: LED headlamps, Keyless GO, and a Parking Package are now included across all trims.
These updates keep the GLB competitive in a rapidly evolving segment, though the lack of a plug-in hybrid option (unlike the electric EQB) may disappoint eco-conscious buyers.
Pros and Cons of the Mercedes GLB 2025

Comparison with Rivals
The Mercedes GLB faces stiff competition in the luxury SUV market. Here’s how it stacks up against key rivals:
| Model | Starting Price | Seating Capacity | Cargo Space (cu ft) | Horsepower | MPG (City/Highway) |
|---|---|---|---|---|---|
| Mercedes GLB 250 | £41,535 | 7 | 62 (with seats folded) | 221 | 25/33 |
| BMW X1 | £39,000 | 5 | 57 | 215 | 26/34 |
| Audi Q3 | £38,500 | 5 | 53 | 190 | 25/32 |
| Land Rover Discovery Sport | £42,000 | 7 | 60 | 200 | 24/30 |
| Skoda Kodiaq | £39,000 | 7 | 65 | 190 | 28/36 |
The GLB’s unique selling point is its 7-seater configuration in a compact package, giving it an edge over the BMW X1 and Audi Q3. However, the Skoda Kodiaq offers more cargo space and a lower price, while the Land Rover Discovery Sport provides a more rugged off-road capability.
Real-World Example: A Family’s Experience with the GLB
To understand the Mercedes GLB in action, consider the experience of Priya, a mother of three from Mumbai. Priya purchased a GLB 220d in 2024 for its blend of luxury and practicality. “The GLB is perfect for our family,” she says. “The third row fits my kids comfortably, and the sliding second row makes it easy to access. The MBUX system is a lifesaver on long drives, keeping everyone entertained.” However, she notes that the boot space is tight with all seats in use, requiring her to pack strategically for road trips.
Priya’s experience highlights the GLB’s appeal for families who need a compact SUV with premium features but don’t require the bulk of a larger model like the GLS.
Pricing and Value
The Mercedes GLB starts at £41,535 for the GLB 200, with the GLB 250 priced around £43,000 and the GLB 35 AMG topping out at £53,395. While the base model is competitively priced among premium 7-seater SUVs, adding options like leather upholstery, a panoramic sunroof, or the AMG Night Package can push the price closer to £60,000. For comparison, the Skoda Kodiaq starts at £39,000, offering similar practicality at a lower cost, but without the Mercedes badge’s prestige.
The GLB holds its value well, thanks to strong demand for SUVs and the brand’s reputation. Running costs are reasonable, with the GLB 200d offering 46p per mile for fleet buyers and an average fuel economy of 42.2 mpg in real-world tests.
