Mercedes-Benz introduces new GLB high-tech hybrid SUV

Mercedes-Benz has presented the new GLB hybrid with 48V system, electric driving capability and MB.OS platform. Explore key features, specs and European launch details.

The new Mercedes-Benz GLB enters the European market with a hybrid system capable of driving briefly on electric power alone — a key shift for the entire model lineup. Instead of a conventional mild hybrid, it combines a new 1.5-litre turbo engine, a 22 kW electric motor integrated into the transmission, and a 1.3 kWh battery, enabling both improved efficiency and a different driving experience in urban conditions.

Sales of the 48-volt hybrid petrol versions have already started in Europe, with prices in Germany beginning at €50,396.50. The range includes several output levels, from 136 to 190 hp for the combustion engine and up to 211 hp in combined system output. Depending on the variant, buyers can choose between front-wheel drive and all-wheel drive.

The defining feature of the new system is its functionality. The electric motor does more than assist acceleration — it actively participates in driving. At typical city speeds, the GLB can run purely on electric power; on open roads, it can coast with the engine disengaged; and during deceleration, it recuperates energy efficiently. This makes the hybrid setup more capable than traditional mild hybrid solutions.

At the same time, the overall concept of the GLB evolves. The model retains its key advantage — seating for up to seven people — while offering more space. The new body grows to around 4.73 metres in length, with an extended wheelbase that improves rear passenger room. When needed, the third-row seats can be folded flat into the floor, preserving interior flexibility.

This combination of space and hybrid technology defines the model’s role in the segment. The GLB remains one of the few compact premium SUVs with a seven-seat configuration, now paired with a more efficient drivetrain without switching entirely to electric propulsion. It broadens the appeal for customers who need versatility but are not ready to move to a full EV.

Digital architecture is another core element. The new GLB is built around MB.OS, Mercedes-Benz’s proprietary operating system, integrating infotainment, comfort functions and driver assistance. It supports over-the-air updates and connects to the brand’s cloud infrastructure. The MBUX interface incorporates solutions based on Google Cloud and Microsoft services, enhancing voice control, navigation and in-car digital features.

Inside, the optional Superscreen setup brings multiple displays, including central and passenger screens up to 14 inches. This reflects a broader shift toward software-defined vehicles, where capabilities can evolve over time through updates.

Safety and assistance systems are also expanded. The GLB comes with a wide range of standard safety features and adaptive cruise control DISTRONIC, while the optional MB.DRIVE ASSIST package adds steering and lane-change support, forming a SAE Level 2 semi-automated driving system.

As a result, the new GLB represents more than a model update. It combines a hybrid drivetrain, increased practicality and a software-driven architecture designed for long-term relevance — shaping its role as a versatile everyday vehicle.
