Mercedes-Benz was recently spotted testing the next-generation GLB in Germany ahead of its 2026 debut.
The new model is retaining some, but not all of its predecessor's boxy looks, and will adopt the German automaker's new Mercedes Modular Architecture (MMA) architecture, offering a wider range of mild-hybrid and full-electric powertrains.
In new images obtained by SEMA News, the vehicle's bodywork is entirely covered in camouflage, but the proportions strongly suggest we're looking at the successor of the three-row GLB rather than the hatchback-style GLA. The SUV appears to have a sleeker design compared to its predecessor, incorporating Mercedes’ new styling language.
The front features slimmer LEDs flanking a large grille that appears to be mounted lower on the front bumper. The greenhouse has been slightly tweaked, as with the upright tail.
Mercedes' entire future compact lineup will ride on the new MMA platform, which is compatible with internal-combustion-engine (ICE) and electric powertrains. We already know most of the options for the upcoming CLA, which will likely find their way under the hood of the GLB.
The fully electric models that will eventually replace the EQB could offer the option between a rear-mounted electric motor with 268 hp, or a dual-motor setup with 375 hp. The electric models will likely be available with 58-kWh and 85-kWh battery packs, although its driving range will be shorter than the 460 miles expected from the more aerodynamic CLA.
The ICE-powered lineup will include a mild-hybrid 1.5L four-cylinder gas engine and a small electric motor inside the eight-speed dual-clutch automatic transmission. The combustion engine is expected to be offered with different outputs, rated at 134 hp, 161 hp and 188 hp, with an additional 27 hp from the electric motor.
Like the current GLB, the new model will offer both front-wheel-drive (FWD) and all-wheel-drive (AWD) configurations. An AMG performance version is also on the horizon, according to sources, likely with some form of hybrid assistance for extra power and efficiency.
