Mercedes GLB Hybrid: a test drive of the mild-hybrid SUV that performs almost like a full hybrid
The second generation of the GLB takes Mercedes’ 48-volt hybridisation technology a step further. It is a technology with which the German manufacturer is launching an offensive in the mid-to-large-sized car segment, positioning it as an alternative to fully electric models. The GLB is the third Mercedes to adopt the 48-volt powertrain, described as a ‘mild hybrid’ but which, in reality, often functions as a full hybrid, propelling the car using electric power alone. The system supports the GLB’s great versatility, which is further emphasised by the functionality of the interior, which can be configured as a seven-seater on request.
Mercedes GLB Hybrid: its powertrains allow it to run on electric power alone
Developed, like the CLA and GLA, on the Mma modular multi-energy platform – which will soon also underpin the new GLA crossover range – the GLB also features the MB.OS supercomputer, which incorporates AI. The platform optimises human-machine interaction by ensuring that every component of the car works together seamlessly to enhance performance, efficiency, dynamism, comfort and digitalisation, tailored to the driver’s style and driving conditions. Like the CLA saloon and Shooting Brake, it is available in three versions featuring 48-volt hybrid technology and an eight-speed dual-clutch gearbox developed for electrified models. All feature a 1.5-litre turbocharged petrol engine with the Miller cycle, available in different power outputs: 136 cavalli for the 180 version, 163 cavalli for the 200 and 190 cavalli for the 220. Inside the gearbox is an electric motor delivering 30 cavalli and 200 Nm of torque, bringing the total power output of the three GLB models to 156 cavalli, 183 cavalli and 211 cavalli respectively. The electric motor, powered by a 1.3 kWh lithium-ion battery, provides additional thrust in certain driving situations or enables the GLB to operate solely on electric power when manoeuvring, in traffic and for short journeys at moderate speeds, for both the front-wheel-drive variants and the 4Matic models with mechanical all-wheel drive, available on the more powerful versions.
Mercedes GLB Hybrid: the boxy-car design is that of a proper SUV
Amidst the proliferation of SUVs that seek to emulate coupés – which, ultimately, are pleasing to the eye but lack practicality – the new GLB makes its debut, retaining the angular lines accentuated by the vertical profile of the previous model’s rear end, albeit slightly softened by its larger dimensions. In fact, its appearance is more closely aligned with that of the G-Class than with that of Mercedes’ other SUVs; it is 4.73 metres long, 1.86 metres wide, 1.69 metres high and has a wheelbase of 2.89 metres. The balance between design and dimensions results in a harmonious, muscular silhouette with a classic off-road character. This personality is defined by the flat flanks, the sculpted lower bodywork and the ground clearance, which create approach, breakover and departure angles suitable for demanding off-road use. The front end incorporates the design language of Mercedes models based on the MMA platform, combining the light signature linking the headlights – including Matrix LED units – with the prominent grille, whilst the rear is characterised by the inverted U-shaped design of the tail lights that run across the tailgate.
