The Mercedes-Benz GLB-Class compact crossover is about to get a series of updates, as evidenced by a prototype spotted recently near Mercedes headquarters in Stuttgart, Germany.

The GLB-Class arrived on the scene in 2019 as a 2022 model and in Mercedes tradition, we should see the updated version arrive in 2023 as a 2024 model.

Mercedes is in the process of updating its entire compact lineup, starting with the A-Class which will be dropped from the US lineup once the updated version is launched. Elsewhere, the updated A-Class, which will again feature hatchback and sedan body styles, is expected to arrive as a 2023 model.

The GLB-class prototype is only lightly camouflaged, which makes sense for an update. There appears to be a revised grille and fascia up front, as well as tweaks inside the lights at both ends.

Interior changes are expected to include a new design for the center console and new graphics for the digital instrument cluster and infotainment center.

It is unclear what is planned for the powertrains. The GLB-Class is currently offered in the United States with 2.0-liter turbocharged inline-4 engines, rated at 250 hp in the GLB 250 grade and 302 hp in AMG’s GLB 35. An electric EGB has been added for 2022 and comes with 225hp (EQB 300) and 288hp (EQB 350) options.

The GLB-Class is a popular option in the Mercedes lineup, with the automaker selling 26,677 units in the United States in 2021. As a result, the vehicle is expected to stick around when Mercedes redesigns its compact lineup around the middle of the decade. The same can’t be said for the A-Class and B-Class, which are set to be phased out as Mercedes focuses more on low-volume, higher-margin vehicles.

Stay tuned for updates as development continues.
