2025 Mercedes-Benz GLB-Class Review

2025 Mercedes-Benz GLB-Class – Overview

At the entry level of Mercedes-Benz’s SUV lineup sit two closely related subcompact models: the 2025 Mercedes-Benz GLB-Class and the slightly smaller, more curvy GLA-Class. Both models share similar pricing and equipment, and are powered by the same 221-horsepower turbocharged four-cylinder engine enhanced with a 48-volt mild-hybrid system. Front-wheel drive comes standard, while all-wheel drive is available as an option.

The GLB stands out for its boxy shape, which translates into greater interior space and the rare option of a third row of seats—making it the more practical choice between the two. On the other hand, the GLA leans toward a sportier, style-focused design. While the GLB handles competently, its driving dynamics aren’t particularly thrilling, though it offers a comfortable ride and a well-appointed cabin.

When it comes to competition, models like the Audi Q3, BMW X1, and Lexus NX tend to provide more standard features, whereas Mercedes often charges extra for options such as lane-departure warning. The GLB also faces internal competition from Mercedes’ own lineup, including the all-electric EQB, the brand’s smallest EV SUV, and the sportier, 302-horsepower AMG GLB 35, which is reviewed separately.

In short, if the GLB appeals to you, there’s a broad range of variants and alternatives to explore within Mercedes-Benz’s lineup.

When Is The 2025 Mercedes-Benz GLB-Class Coming Out?

The 2025 Mercedes-Benz GLB-Class is scheduled to hit dealerships in the U.S. and major global markets in the fall of 2024, aligning with the typical model year rollout strategy. Pre-orders have already opened, and Mercedes-Benz dealerships are gearing up for deliveries.

For those eager to experience the GLB firsthand, Mercedes-Benz typically offers extensive test-drive opportunities once the vehicles start arriving. Early adopters will find the 2025 GLB available in multiple trims and configurations, including both front-wheel-drive and all-wheel-drive versions, depending on the market.

What’s New for 2025 Mercedes-Benz GLB-Class?

For 2025, Mercedes-Benz has made a few subtle updates to the GLB-Class. The most notable addition is the Night Package Lite, a new appearance package that gives the GLB a sleek, dark-themed exterior look with blacked-out accents for a sportier presence. Additionally, the 360-degree surround-view camera system is now available as a standalone option, enhancing visibility and maneuverability without requiring additional packages.

Pricing and Which One to Buy

The 2025 Mercedes-Benz GLB-Class starts at $46,950, with prices rising to around $51,900 depending on the trim level and optional features chosen.

Under the hood, the GLB is offered with a single powertrain: a turbocharged 2.0-liter four-cylinder engine. Buyers can opt for the 4MATIC all-wheel-drive system for an additional cost of a few thousand dollars, providing improved traction and stability in varied driving conditions.

When choosing options, we recommend adding the Driver Assistance Package, which bundles valuable safety features such as adaptive cruise control and lane-keeping assist — enhancing both convenience and safety on the road. For audiophiles, the optional Burmester surround-sound system with Dolby Atmos audio is worth the extra investment, delivering a rich, immersive listening experience that complements the luxury cabin.

Engine, Transmission, and Performance

Beneath the iconic Mercedes-Benz grille, the 2025 GLB is powered by a turbocharged 2.0-liter four-cylinder engine that delivers 221 horsepower and 258 pound-feet of torque. Building on last year’s update, this engine is paired with a 48-volt mild-hybrid system, which includes a starter-generator capable of providing an extra 13 horsepower boost under certain driving conditions, improving responsiveness and efficiency.

The powertrain is mated to an eight-speed dual-clutch automatic transmission, offering smooth and quick gear shifts. Buyers can choose between front-wheel drive or the more capable 4MATIC all-wheel-drive system, which enhances traction in slippery or rough conditions.

While the GLB 250 doesn’t offer sporty driving thrills, its handling is confident and composed, providing a comfortable and controlled ride that fits well with the expectations of a compact luxury SUV. It strikes a good balance between everyday drivability and the refinement expected from Mercedes-Benz.

0–60-MPH Times

Although we haven’t yet tested the 2025 Mercedes-Benz GLB-Class updated powertrain with the mild-hybrid system, the previous all-wheel-drive GLB model managed a respectable 6.0-second sprint from 0 to 60 mph without the benefit of the 48-volt setup. With the mild-hybrid boost, the newer version is expected to deliver similar or slightly improved acceleration figures, offering brisk performance suitable for everyday driving needs.

Fuel Economy and Real-World MPG

Thanks to the addition of the 48-volt mild-hybrid system, the 2025 Mercedes-Benz GLB-Class achieves improved fuel efficiency compared to previous models. The front-wheel-drive GLB 250 earns an EPA-estimated 25 mpg in the city and 33 mpg on the highway. Opting for the all-wheel-drive 4MATIC version reduces city mileage slightly by 1 mpg, reflecting the added drivetrain weight.

We have yet to conduct our own real-world 200-mile highway fuel economy test at 75 mph with the updated powertrain, but we plan to update this review once those results become available. For the latest and detailed fuel economy figures, you can also visit the EPA’s official website.

Interior, Comfort, and Cargo

The 2025 Mercedes-Benz GLB-Class offers a surprisingly spacious interior for a subcompact luxury SUV. It provides 20 cubic feet of cargo space behind the second-row seats, expanding to an impressive 62 cubic feet with the rear seats folded down — cargo capacity that rivals that of larger SUVs like the BMW X3.

While the base GLB model’s interior trim is somewhat modest, it does come equipped with key comfort features such as power-adjustable heated front seats, dual-zone automatic climate control, and a tilt-and-telescoping steering wheel as standard. Ventilated seats are available but require an upgrade.

One of the GLB’s standout options is the small third-row seat, which, although best suited for children, provides valuable additional passenger capacity, making the GLB a rare seven-passenger vehicle in its segment.

Given the upscale nature of the brand, many buyers will likely invest in luxury upgrades such as leather upholstery, ambient interior lighting, and other premium touches to enhance comfort and style.

Infotainment and Connectivity

Although the 2025 Mercedes-Benz GLB-Class may not offer an abundance of standard interior features, it shines when it comes to infotainment and technology. Every GLB 250 comes equipped with a pair of crisp 12.3-inch digital displays—one serving as the instrument cluster and the other as the central touchscreen for media and vehicle controls.

Connectivity options are plentiful, including wireless Apple CarPlay and Android Auto, ensuring seamless smartphone integration without the clutter of cables. The GLB also features four USB-C ports for charging and device connection, as well as Bluetooth for easy wireless audio streaming and hands-free calling.

This well-rounded tech setup provides drivers and passengers with modern convenience and entertainment, keeping the GLB competitive in its class.

Safety and Driver-Assistance Features

The 2025 Mercedes-Benz GLB-Class comes equipped with a solid suite of standard and available safety technologies to help keep drivers and passengers protected.

Standard features include cruise control, active brake assist, and adaptive braking systems that enhance stopping power in emergencies. For those seeking advanced driver aids, the GLB offers optional features such as adaptive cruise control with lane-centering capability, lane-keeping assist, and active blind-spot assist to provide added confidence on highways and in heavy traffic.

Key safety technologies on the GLB include:

• Automated emergency braking with pedestrian detection (standard)

• Lane-departure warning with lane-keeping assist (available)

• Adaptive cruise control with lane-centering (available)

For the latest crash test results and detailed safety ratings, prospective buyers can refer to the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) websites.

Warranty and Maintenance Coverage

Mercedes-Benz provides warranty coverage for the 2025 GLB-Class that aligns closely with its luxury competitors, though it lacks some perks offered by rivals like the BMW X1 or Jaguar E-Pace.

• The limited warranty covers the vehicle for four years or 50,000 miles.

• The powertrain warranty matches this coverage, also lasting four years or 50,000 miles.

• Unlike some competitors, Mercedes-Benz does not include complimentary scheduled maintenance with the GLB, meaning routine services like oil changes and inspections are paid separately by the owner.

While the warranty terms provide solid protection, buyers should factor in ongoing maintenance costs when budgeting for ownership.

Final Verdict

The 2025 Mercedes-Benz GLB-Class remains a standout in the compact luxury SUV segment, offering a rare blend of versatility, style, and technology at a competitive price. Its optional third-row seating sets it apart, catering well to small families or those who occasionally need to transport more passengers. The GLB’s mild-hybrid powertrain improvements help keep it efficient and responsive, while the AMG GLB 35 injects serious fun for performance enthusiasts.

Mercedes-Benz’s strong safety credentials, generous warranty, and premium cabin comfort round out a compelling package. The GLB isn’t the most athletic or the most luxurious in its class, but it excels at being a practical, well-rounded luxury SUV with broad appeal.
