All-New Mercedes-Benz GLB unveiled: new design, bigger cabin, and petrol & BEV options

The all-new 2026 Mercedes-Benz GLB has made its world debut, bringing a more spacious interior, an all-new design, a Superscreen interface, and two powertrain choices — petrol and fully electric.

The vehicle has been improved in both driving dynamics and refinement, thanks to its switch to the more modern Mercedes-Benz Modular Architecture (MMA), replacing the previous-generation MFA2 platform.
In terms of design, the new GLB retains its upright stance similar to the current model, but adopts a completely new and more rounded design language. Three-pointed-star motifs are integrated into the headlights, tail-lights, and front grille, along with a full-width light bar at the rear. Its boxy silhouette reflects its practicality-first concept, supporting both 5- and 7-seat configurations, with the second row able to slide forward to increase cargo space.

The highlight of the cabin is Mercedes-Benz’s latest MBUX Superscreen, stretching across the entire dashboard. Higher variants feature a 10.25-inch driver display, a 14-inch central touchscreen, and a 14-inch passenger display, forming a continuous glass panel.
The MBUX system integrates Google Maps for navigation and comes with AI that learns driver behaviour. Wireless charging, multiple USB-C ports, and selectable ambient lighting are also included.

In the electric versions, boot space measures 540/480 litres (5-seat / 7-seat), expanding to 1715/1605 litres with the rear seats folded. There is also a 127-litre front storage compartment (frunk).

Two electric variants are available: the single-motor GLB250+ and the dual-motor GLB350+ 4Matic. Both use an 85kWh battery pack. Mercedes claims a driving range of 542–631 km for the GLB250+ and 521–614 km for the GLB350+ 4Matic. The 800-volt electrical architecture supports DC fast charging up to 320kW (adding 260 km in 10 minutes, claimed) and 22kW AC charging.

The GLB250+ produces 200kW (272 PS) and 335 Nm, while the GLB350+ 4Matic delivers 260kW (354 PS) and 515 Nm, achieving 0–100 km/h in 7.4 seconds and 5.5 seconds respectively. In normal driving, the 4Matic primarily uses the rear motor, with the front motor engaging when extra power or traction is required.

The petrol-powered model uses a 1.5-litre turbo engine paired with a 48-volt mild-hybrid system and an 8-speed dual-clutch transmission, providing smoother response and improved efficiency. Buyers can choose between front-wheel drive or 4Matic all-wheel drive.

The new GLB is equipped with a wide range of driver-assistance systems, including Distronic adaptive cruise control as standard in Europe. European models come with eight cameras, five radar sensors, 12 ultrasonic sensors, and a water-cooled high-performance computer ready for future functions and over-the-air updates.
