Mercedes-Benz’s smallest three-row SUV is about to receive one of its biggest interior upgrades yet. The next-generation Mercedes-Benz GLB has resurfaced—this time not through spy photos, but through official images released by the automaker showcasing the compact luxury SUV undergoing extreme cold-weather testing. The prototype is blanketed in frost after a session inside a climate-controlled wind tunnel, cleverly hiding any exterior changes. But the real news is what’s happening inside.
A Fully Exposed Cabin Reveals a “Superscreen” Dashboard
While the ice-covered exterior keeps the GLB’s new sheetmetal a mystery, Mercedes has lifted the curtain on the SUV’s revamped cabin. The headline feature is the brand’s optional Superscreen, a wide, dashboard-spanning display setup that sits below the more advanced Hyperscreen used in its flagship electric models.
Based on the images, the Superscreen consists of:
- A large central infotainment display
- A matching passenger-side display
- A slightly smaller digital instrument cluster behind the steering wheel





Together, they form a “wall of screens” that transforms the GLB’s interior into a modern digital cockpit, aligning the model with Mercedes-Benz’s latest technology-first design philosophy. The company didn’t release exact specifications, but the visuals make clear that the GLB is moving decidedly upmarket in terms of in-car tech.
Ambient Lighting and Panoramic Roof Get a Stylish Upgrade
Mercedes also highlighted new interior ambient lighting, including a star-pattern LED effect integrated into the panoramic roof sunshade—another upscale touch borrowed from the brand’s higher-tier models. For a subcompact SUV, the GLB continues to stand out with its clever packaging, making room for an optional third row. The new photos reaffirm that the high roof line remains, preserving headroom for passengers beyond the second row.





Frost Hides Exterior Tweaks, but the Family Shape Remains
The thick frost built up during the GLB’s wind-tunnel test disguises most of the exterior design. However, the prototype still clearly carries its signature boxy silhouette and tall rear roof—key for practicality and cargo space in the compact SUV segment. Even the snowflake-style wheels seem intentionally seasonal, as though Mercedes wanted the cold-weather theme to feel complete.
Full Reveal Coming December 8
Mercedes-Benz confirmed that the next-generation GLB will make its official debut on December 8. Given what the brand has shown so far—a tech-heavy interior, a redesigned infotainment architecture, and upgraded lighting—the refreshed GLB appears poised to strengthen its position in the compact luxury SUV market.
Stay tuned for full details when Mercedes drops the cover next month.
