The next-generation Mercedes-Benz GLB is set to make its official debut next year, and while it will retain the signature boxy character that made the current model popular, expect softer, more refined styling with rounded corners. It’s part of Mercedes’ larger strategy to modernize its compact vehicle lineup while still preserving the identity of its existing models.
Design
Though Mercedes has only teased the upcoming GLB so far, what’s clear is that the new design will keep the upright stance and SUV proportions of the outgoing version. However, it will adopt smoother edges, aligning it with the brand’s updated design language. The goal is to strike a balance between rugged appeal and aerodynamic efficiency, especially with electrification in focus.
Platform
One of the biggest upgrades for the new GLB is the shift to the Mercedes Modular Architecture (MMA). This new platform is set to underpin Mercedes’ future compact vehicles, including the new CLA and GLA. The MMA platform is flexible enough to support both internal combustion engines (ICE) and fully electric drivetrains, giving buyers more choice than ever before.
This architecture also allows for clever packaging, better interior space, and the integration of new tech and safety features. And yes, this also means improved driving dynamics and efficiency across the range.
Powertrains
The next-gen GLB will come with a mix of powertrain options, including mild-hybrid petrol engines and full-electric versions. For the ICE variants, expect a 1.5-litre, four-cylinder turbo-petrol engine mated to an eight-speed dual-clutch automatic transmission. It will be available in three power outputs—134bhp, 161bhp, and 188bhp. An integrated 48V mild-hybrid system will add another 27bhp of electric boost, improving both performance and fuel efficiency.
As for the EVs, these will eventually replace the EQB and offer serious upgrades. The electric versions of the GLB are expected to come with either a single rear-mounted motor producing 268bhp or a dual-motor AWD setup generating 375bhp. Battery options will include 58kWh and 85kWh packs. While range figures are expected to be solid, they will likely fall short of the 750km claimed for the upcoming CLA, mainly due to the GLB’s boxier shape.
Drivetrain and Variants
The GLB will continue to offer both front-wheel-drive and all-wheel-drive options across its line-up. This gives it a wide range of appeal—from city dwellers looking for space and efficiency, to those needing better traction and performance in tougher conditions.
And of course, performance fans can look forward to an AMG version. While Mercedes hasn’t shared specifics yet, it’s safe to assume the AMG GLB will use some form of hybrid assistance to deliver higher output figures while meeting stricter emissions standards.
Outlook
Mercedes may be sunsetting models like the A-Class and B-Class, but its future compact range is shaping up to be stronger and smarter than ever. With the new GLB, the brand is not just refreshing its popular compact SUV but also preparing it for the electrified and digital future of driving.
