Mercedes-Benz is preparing to unveil the updated GLB crossover on December 8th, and recent sightings with decreasing camouflage reveal significant changes. The next GLB will feature an electric powertrain option alongside more conventional hybrid setups, with a design that closely echoes the Smart #5.
Evolutionary Exterior Design
The crossover’s profile has been exposed, confirming an evolutionary rather than revolutionary design direction. Flush-mounted door handles, a similar greenhouse shape, and pronounced rear haunches all point to strong design cues from the Smart #5. This is not accidental – Mercedes appears to be streamlining its compact vehicle lines. The front and rear are still under wraps, but early indications show streamlined bodywork and new, star-shaped headlights. The rear end has also been reworked, with vertical taillights connected by an illuminated bar, and the license plate has been moved to the bumper.
High-Tech Interior with Superscreen Option
Earlier this month, Mercedes previewed the GLB’s interior, which will offer an optional MBUX Superscreen. This system combines a 10.25-inch digital instrument cluster, a 14-inch infotainment display, and another 14-inch screen for the front passenger. A new steering wheel, floating center console, and wireless smartphone charging are also included.
The GLB will be available in both five- and seven-seat configurations, with improved legroom and headroom in the second row, as well as easier access to the third row. A standard panoramic glass roof will be offered, with an optional illuminated “starry sky” version that can transition from clear to opaque almost instantly.
Powertrain Options: Electric and Hybrid
The new GLB is expected to share powertrain options with the CLA, including an 85 kWh battery pack for the electric variant. Two electric motors will be available at launch: a single-motor rear-wheel drive version with 268 hp and 247 lb-ft of torque, and a dual-motor all-wheel drive system producing 349 hp and 380 lb-ft.
A hybrid powertrain will also be offered, using a 1.5-liter four-cylinder engine, a 1.3 kWh battery pack, and an eight-speed dual-clutch transmission. This setup will deliver between 154 hp and 181 hp, depending on the configuration.
The design and feature similarities between the GLB and Smart #5 indicate a more unified approach to compact vehicle design within the Mercedes-Benz portfolio. This suggests future models may share even more components, streamlining production and reducing costs.
