The next-generation Mercedes-Benz GLB is gearing up for its global debut on 8 December 2025, and Mercedes has dropped the first official interior images and details ahead of that date.
Here’s a summary of what we know so far.
Dashboard & Infotainment
- The GLB takes inspiration from its sibling, the new CLA, adopting a screen-heavy dashboard. In particular, buyers have the option of a full-width “Superscreen” (or “Hyperscreen” style) that spans from driver to passenger.
- The layout reportedly includes a standard 10.25-inch digital instrument cluster, and dual 14-inch displays for centre and passenger (when fitted).
- Underneath the screens: physical touches remain. The new steering wheel reintroduces rocker switches for cruise control and a roller knob for volume – feedback from customers apparently led Mercedes to retain these more tactile controls.
- The centre console adopts a “floating” design, giving a sense of lightness and additional storage space between the front seats.
Seating & Space
- The GLB continues to offer both five- and seven-seat configurations. The third row remains optional for up to seven passengers.
- Mercedes emphasizes more headroom and legroom for the first two rows compared to the outgoing model. The second row now also has a sliding and reclining bench (standard on seven-seat versions, optional on five-seat) to enhance flexibility.
- Access to the third row is improved via an easier “Easy-Entry” function, and when folded, the seats lie flat into the floor, improving versatility.
Roof, Materials & Ambience
- A panoramic glass roof is standard across the range. Optional features include an electrochromic “clear-to-opaque” function and a special illuminated star pattern embedded in the roof glass (creating a night-sky effect).
- The cabin’s ambience is described as “cleaner, high-tech” compared to the outgoing model—moving away from heavier sculptural forms to simpler, premium surfaces.
Tech, Driver Assistance & Platform
- The GLB adopts the latest MB.OS operating system and fourth-generation MBUX infotainment platform, bringing features like 3D navigation, virtual assistant, and deeper connectivity.
- On the assistance side, hardware includes eight cameras, five radar sensors, and 12 ultrasonic sensors, supporting an advanced driver-aid suite.
- The vehicle is built on the new Mercedes Modular Architecture (MMA) platform – enhancing structural flexibility and helping achieve the claimed improvements in cabin packaging.
Practicalities & Highlights
- The floating centre console opens up more usable space between the front seats for items like wireless charging, cup-holders, and storage.
- The second-row sliding function means you can favour more space for row two (e.g., longer legroom) or more third-row access/cargo space, depending on configuration.
- Mercedes says the cabin climate and comfort performance have been heavily tested, with improved heating efficiency in cold conditions and better thermal insulation thanks to the new architecture.
What to Expect & Timing
- The official global debut is set for 8 December 2025.
- Deliveries are expected to begin in early 2026.
- While the interior shots mostly reference the electric-variant (with “EQ Technology”) GLB, a version with combustion/hybrid powertrains is also expected.
Why This Interior Matters
In a segment where premium compact SUVs increasingly lean into high-tech and flexible cabin design, the new GLB’s interior highlights (three-screen layout, panoramic roof with special effects, improved packaging for families) are clearly aimed at standing out.
The optional third row keeps it attractive for buyers needing occasional extra seats, while the floating console and enhanced second-row comfort work well for those focused on everyday usability. Mercedes’ re-use of tactile controls (rocker switches, roller knob) alongside the futuristic screens suggests a balanced approach between tech-luxury and ergonomic usability.
Summary
The next-generation GLB impresses with a fresh, tech-rich cabin that doesn’t sacrifice practicality. As the global unveiling approaches, we’ll get full specs, powertrain breakdowns, and regional details — but as far as interior design goes, Mercedes has raised the bar for what a compact luxury SUV cabin can offer.
