2025 Mercedes-Benz GLB Review — Luxury Compact SUV for Modern Families

The 2025 Mercedes-Benz GLB is a premium compact SUV designed to bridge practicality and luxury. Positioned between the GLA and GLC, it offers the flexibility of a small SUV with the sophistication of a full-size Mercedes. Competing directly with the BMW X1, the GLB blends strong performance, refined comfort, and advanced driver assistance systems.

With its optional third-row seating, the GLB accommodates up to seven passengers — a rare feature in its class. It’s an ideal choice for small families or professionals who value premium craftsmanship, smart technology, and daily usability.

Distinctive Exterior and Dimensions

The Mercedes-Benz GLB stands out with its confident, boxy design and urban SUV proportions. It measures approximately 4,638 mm long, 1,834 mm wide, and 1,696 mm high, with a wheelbase of 2,830 mm. These dimensions provide a strong presence while keeping maneuverability ideal for city driving.

The front fascia features a bold Mercedes grille with chrome accents and integrated LED headlights. Its upright body lines and squared-off rear give it a rugged yet elegant personality. Optional 19- and 20-inch wheels, along with color options like Polar White, Mountain Gray, and Denim Blue, enhance the GLB’s stylish individuality.

Aerodynamic elements and subtle chrome touches add refinement, while the high-roof design contributes to spacious headroom inside. Overall, the GLB maintains a modern look that confidently reflects Mercedes-Benz luxury DNA.

Mercedes-Benz GLB Premium Interior and Technology

Inside, the 2025 GLB welcomes passengers with a blend of functionality and upscale materials. It seats five adults comfortably, with an optional third row for occasional passengers or children. The cabin is wrapped in soft-touch surfaces and brushed aluminum details, complemented by customizable ambient lighting in 64 colors.

The digital cockpit integrates two 10.25-inch displays — one for the driver’s instrument cluster and another for infotainment. Powered by the MBUX system, the setup supports natural voice commands, smartphone connectivity, and over-the-air software updates.

Rear passengers enjoy generous legroom and reclining seatbacks, while cargo capacity reaches 12.4 cubic feet behind the second row and expands to over 60 cubic feet when folded. Dual-zone climate control, wireless charging, and premium Burmester audio create a comfortable environment for both short trips and long journeys.

Powertrain, Performance, and Driving Experience

The GLB 250 uses a 2.0-liter turbocharged inline-4 engine paired with a 48-volt mild hybrid system, delivering 190 horsepower and 300 N·m of torque. An 8-speed dual-clutch automatic transmission ensures smooth power delivery, while 4MATIC all-wheel drive offers confident handling across varied road conditions.

The SUV accelerates from 0 to 100 km/h in 8.6 seconds, balancing efficiency and agility. Fuel consumption averages 7.2 L per 100 km, making it a practical yet spirited performer. For those seeking sportier dynamics, the AMG GLB 35 raises output to 300 hp, introducing adaptive suspension and performance-tuned driving modes.

On the road, the GLB feels composed and predictable. The suspension absorbs imperfections well, and steering feedback remains precise. Whether navigating urban streets or highways, the GLB maintains a refined, confident ride that embodies Mercedes engineering quality.

Intelligent Safety and Driver Assistance

Technology is at the heart of the 2025 GLB. The SUV includes advanced driver-assistance features such as adaptive cruise control, lane-keeping assist, blind-spot detection, and automatic emergency braking. Optional features include a 360-degree camera, self-parking assist, and traffic-sign recognition, further improving convenience and safety.

The intelligent MBUX interface enhances everyday usability with voice control and AI-based learning that adapts to driver habits. It can adjust seat position, temperature, and navigation routes automatically over time. Connectivity remains a highlight, with wireless Apple CarPlay, Android Auto, and remote vehicle control via the Mercedes Me app.

With its smart integration of safety and comfort systems, the GLB exemplifies modern driving confidence — merging practicality with advanced automation for a safer, more relaxed journey.
