Mercedes-Benz has officially unveiled the second-generation GLB, a major step forward for the brand’s compact luxury SUV line-up. The new GLB arrives first as an all-electric model replacing the EQB while petrol, diesel and mild-hybrid powertrains will follow in select markets. Built on the advanced MMA platform, the seven-seat SUV blends bold design, segment-leading range, expanded practicality and an interior dominated by next-generation artificial intelligence.
With a fully re-engineered body, a larger footprint and a technology suite shared with the new CLA, the 2026 GLB marks a pivotal turning point in Mercedes’ global EV strategy.
Key Takeaways: 2026 Mercedes-Benz GLB Global Unveil
- 2026 GLB debuts as an EV-first SUV, replacing the EQB, with ICE and hybrid options coming later in global markets.
- 631km WLTP range for the GLB 250+ and 614km WLTP for the GLB 350 4Matic using an 85kWh battery and 800V architecture.
- MMA platform supports 5- and 7-seat layouts, improved space, new crash structures and faster charging capabilities up to 320kW.
- Superscreen interior with three digital displays and fourth-gen MBUX powered by Google, Microsoft and ChatGPT AI.
- Significant growth in dimensions: 98mm longer, 27mm wider, 14mm lower, and a 60mm wheelbase expansion for better comfort.
- India will get the GLB only with petrol and diesel engines, imported fully built, unlike the CLA which arrives solely as an EV.
A Bold New Chapter: Design Inspired by Utility and Luxury
The 2026 GLB stays true to its predecessor’s upright, boxy stance, echoing the rugged aura of the G-Class while evolving into a more expressive and aerodynamic form. Mercedes has sharpened the lines, stretched the proportions and introduced entirely new lighting signatures at both ends.
At the front, the GLB features redesigned LED headlamps with intricate star-shaped DRLs connected by a full-width light bar. The grille—one of the most discussed elements—grows significantly larger and incorporates dozens of illuminated stars in EV models. ICE variants maintain a functional chrome-star-pattern grille with an illuminated frame, giving both versions distinct personalities without splitting the design language.
The rear design is even more polarising. Inspired by the Vision EQXX concept, vertically stacked taillights are joined by a slim horizontal strip. Combined with a steep, upright window and boxy roofline, the GLB continues to prioritise practicality without abandoning futuristic styling cues.
Bigger, Longer, Smarter: The GLB’s New Dimensions
Mercedes has increased the GLB’s size in nearly every direction to enhance its cabin usability.
Below is a table comparing the new model with the previous generation:
| Dimension | New GLB | Change |
| Length | 4.73 m | +98 mm |
| Width | 1.86 m | +27 mm |
| Height | 1.68 m | -14 mm |
| Wheelbase | 2.89 m | +60 mm |
This growth improves headroom by up to 35mm in the front, up to 68mm in the second row, and 10mm in the third row. The stretched wheelbase also significantly boosts legroom, making long journeys more comfortable.
The GLB continues to offer five- and seven-seat configurations, with the third row now accommodating passengers up to 5ft 6in (1.71m). Access to the back is easier due to a longer adjustment range for the second-row bench and wider rear door openings.
Boot Space and Two Trunks: Practicality Remains a Priority
The GLB strengthens its reputation as a practical family SUV. Mercedes has expanded load capacity and introduced a new innovation—a front trunk.
| Storage Area | Capacity |
| Rear boot (5-seater) | 540 L |
| Rear boot (7-seater) | 480 L |
| Max load space (5/7-seat) | 1715 L / 1605 L |
| Front trunk (frunk) | 127 L |
The frunk alone can store items like tents, crates, or travel bags. The GLB remains one of the few compact luxury SUVs offering a usable third row and dual storage areas.

Inside the GLB: Three Screens, AI Everywhere and a New Interior Philosophy
Mercedes describes the new cabin as a “massive step up”, and for good reason. The centrepiece is the optional Superscreen—a continuous panel housing:
- 10.25-inch driver display
- 14-inch central touchscreen
- 14-inch passenger display
The system is powered by fourth-generation MBUX, using a Unity game engine for graphics, while AI from Microsoft, Google and ChatGPT-4o enables natural conversations, contextual support and personalised navigation.
Mercedes has reintroduced physical controls where customers demanded them most—volume rollers, adaptive cruise switches and rocker controls return to improve everyday usability.
Passengers also benefit from increased comfort, a star-etched panoramic sunroof with 158 illuminated stars and a redesigned steering wheel with more intuitive controls.
Electric Powertrains: Efficiency, Range and Performance
At launch, two EV variants headline the GLB line-up.
GLB 250+ with EQ Technology (RWD)
- 268 hp
- 335 Nm (454 Nm with boost)
- 0–100 km/h: 7.4 sec
- WLTP range: 630–631 km
- Battery: 85 kWh
GLB 350 4Matic with EQ Technology (AWD)
- 349 hp
- 515 Nm
- 0–100 km/h: 5.5 sec
- WLTP range: 614–615 km
- Battery: 85 kWh
Both share a sophisticated 800V architecture, enabling:
- Up to 320kW DC fast charging
- 10–80% charge in 22 minutes
- Up to 260 km range added in 10 minutes
- Optional DC converter for widespread 400V chargers
Mercedes will later introduce a GLB 200 EV with a more affordable 58 kWh LFP battery and a 48V mild-hybrid petrol version using a 1.5-litre turbo engine developed with Horse.
India Plans: GLB to Arrive as CBU With ICE Engines Only
While the global GLB launches as an EV-first model, Mercedes has confirmed that India will receive only petrol and diesel versions, imported as fully built units. Hybrid and EV variants are not expected initially, positioning the new GLB as a premium niche product targeting luxury SUV buyers seeking seven seats.
A Defining Shift for Mercedes in the Compact SUV Segment
The 2026 Mercedes-Benz GLB represents more than a generational update—it is a strategic reboot of the brand’s compact luxury SUV portfolio. By merging bold design, long-range electric performance, a roomier three-row cabin and a revolutionary AI-powered interior, Mercedes has moved the GLB into a league of its own.
With few direct seven-seat EV rivals, the new GLB is poised to become a central figure in Mercedes’ push toward technologically advanced, highly practical electric mobility.
