New Mercedes GLB features new platform, various powertrains

The next-generation Mercedes-Benz GLB launches in 2026 and will evidently be a significant improvement on the outgoing model.

It is just one of myriad new entrants from the brand, due out over the next couple of years.

The new GLB will retain the upright silhouette of the 2019 model but external dimensions increase, meaning improved interior and luggage space. Expect a bolder-looking fascia with new lighting signatures too. 

Underpinning the GLB is the new Mercedes-Benz Modular Architecture (MMA). Like its CLA platform-mate, GLB will come with either electric or petrol drivetrains, you choose. Both come with GLB badges, so the EQB nomenclature disappears. However, the electric variant will state it is a GLB with EQ technology.

Also new for GLB is an off-road package that brings a more rugged look.

Inside, GLB will mimic the latest CLA by adopting a full-width digital display panel for instruments and infotainment. Expect more soft surfaces and an expansion of physical controls. Like its predecessor, the new GLB will retain its seven-seat status.

Another change is a move to an 800V system for the electric GLB, for faster charging (up to 320kW). It also supports single-motor rear-wheel drive – this gets a two-speed transmission – and dual-motor four-wheel drive variants. Power outputs are expected to range from 172 to 265kW, with battery capacities of 58 to 85kWh.

Sportier AMG-badged variants are expected, with axial-flux electric motors and dedicated cylindrical-cell battery technology.

EVs will take precedence but mild hybrid petrol versions will also be available. These will run a 1.5-litre turbopetrol producing either 101kW or 142kW, driving the front wheels or all four on higher specification versions.

Launching next year, in EV form first, the GLB will go up against Audi Q3 and BMW X1.
