New Gen Mercedes-Benz GLB Makes Global Debut — With EV and Hybrid Powertrains
New Gen Mercedes-Benz GLB makes global debut, and it comes with a host of updates that reshape its identity while staying true to what made the GLB popular. The all-new GLB — revealed December 8, 2025 — embraces both EV and mild-hybrid powertrains, expanded dimensions, refined technology and flexible seating.
The new-generation Mercedes-Benz GLB revealed globally with a bolder look, modern styling cues and a focus on electrified powertrains.
This global debut marks a major evolution for the compact-luxury SUV and positions GLB for a modern, electrified SUV marketplace.
Bigger, Roomier and More Flexible
One of the key highlights of the new GLB is its increased size and versatility. The vehicle now rides on the updated MMA architecture — a platform shared with the latest compact models from Mercedes.
- The wheelbase has grown by about 60 mm, which translates into a notably more spacious second row and easier access to the optional third row.
- Overall, the new GLB is reportedly 98 mm longer and 27 mm wider, giving it a more substantial road presence while still offering a compact-SUV footprint.
- The flexible interior layout continues to support both 5-seat and 7-seat configurations, making it practical for families or groups.
In short: the new GLB offers more comfort, flexibility and usability without sacrificing the manageable size that makes it ideal for urban driving as well as highway cruising.

Powertrain Options: Electric First, Hybrids Next
A big shift: the new GLB will launch globally initially as an electric-first offering, with mild-hybrid variants to follow later.
- The EV version — branded under GLB with EQ Technology — marks a replacement of the older EQB in the Mercedes lineup.
- The hybrid versions, expected soon after, will bring in a 48-volt mild-hybrid setup paired with a compact turbocharged petrol engine — reminiscent of the new Mercedes CLA and its platform-sharing underpinnings.
This dual-powertrain strategy reflects Mercedes-Benz’s broader shift toward electrification while still catering to markets and buyers who prefer traditional or hybrid engines.

Interior and Tech: Digital, Spacious and High-Tech
Inside, the new GLB receives a major upgrade — especially in terms of technology and comfort.
- The optional MBUX Superscreen — a panoramic, multi-display digital cockpit — remains the centrepiece. It features a 10.25-inch driver display plus a 14-inch central touchscreen and an optional 14-inch passenger display.
- The dashboard design mimics the aesthetic of the recently updated compact Mercedes lineup, blending minimalism with functionality. Steering controls have been simplified, replacing previous touch-sensitive panels with rocker switches — echoing the changes seen on the new CLA.
- The GLB retains the option for a glass panoramic roof, abundant headroom and flexible seating — making it well-suited for urban commuting as well as long-distance family or group travel.
All told, the cabin of the new GLB aims to merge luxury, comfort and modern convenience — a compelling package in a compact SUV format.

Styling: A Fresh Look With Familiar Roots
Visually, the new GLB may appear evolutionary rather than revolutionary — but the updates lend it a more contemporary, sophisticated character.
- The front fascia adopts a bolder grille with a dominant three-pointed star, combined with updated LED headlamps and modern design cues that align with Mercedes latest design language.
- While maintaining the classic boxy-silhouette that defines the GLB identity, the proportions are more muscular and balanced — giving the SUV a confident, upright stance.
- The design tweaks reflect a clear intention: offer a SUV that looks refined and contemporary yet retains a spirit of practicality and space that has always been GLB’s strength.

What It Means for India (and Global Buyers)
For buyers in India and many other markets, the new gen GLB presents an appealing package — but with caveats.
- As per early information, when it comes to India, the GLB will be sold in petrol and diesel (ICE) guises, rather than electric — for now.
- Thanks to its compact luxury-SUV size combined with optional third-row seating, it fills a niche: a relatively affordable (for Mercedes standards), practical yet premium 7-seater SUV, somewhere between a city car and a large SUV.
- Globally, the EV-first strategy (with hybrids to follow) hints at Mercedes-Benz’s push toward electrification — but the continued availability of ICE models suggests they are still consciously catering to markets where EV infrastructure or demand may lag.

What Still Isn’t Public (But We Guess Might Matter)
Because the debut is fresh, there remain open questions — and potential uncertainties — about the new GLB.
- Final pricing and trim-by-trim specifications (especially for markets outside Europe) are not yet widely published.
- For many markets, it’s unclear which powertrain variants will be offered, especially whether EV, hybrid and ICE will all coexist.
- While the new GLB gains in size and refinement, the real-world dynamics — around ride comfort, SUV handling, fuel/energy economy and maintenance — will only be known once deliveries actually begin globally (planned early 2026).
Optional third-row seats make the new GLB a practical seven-seater SUV.
Verdict: A Smart Evolution — and a Strong Move
The new gen GLB seems like a smart balancing act. The core identity — a compact yet versatile SUV with the option of 7-seat flexibility — remains intact. But Mercedes-Benz has layered on meaningful upgrades: modern design, more space, contemporary interiors and electrified powertrain choices.
For someone wanting a premium SUV that can handle both city driving and occasional long trips, with room for family or friends — the new GLB looks like it might deliver. Add to that the technology, build quality and badge value that come with the brand, it may well be a compelling choice when it finally lands in markets worldwide (including India, albeit in ICE form first).
For early adopters, the New Gen Mercedes-Benz GLB makes global debut — it’s a statement that Mercedes is adapting to changing tastes, while preserving practicality and versatility.
FAQs – New Gen Mercedes-Benz GLB Makes Global Debut
FAQ 1: When exactly did Mercedes show the new GLB?
Mercedes pulled the covers off the new GLB on December 8, 2025. It wasn’t one of those over-the-top reveals, but the message was clear: this SUV is moving into a more modern, electrified phase.
FAQ 2. Is Mercedes turning the GLB into an EV-only SUV now?
Not really. The electric version is getting early attention, but that doesn’t mean petrol or hybrid models are gone. Mercedes is simply leading with the EV this time, then filling in the rest of the lineup depending on market response.
FAQ 3. Why is the electric version getting priority?
Part of it is emissions, part of it is direction. Mercedes is slowly simplifying its compact range, and pushing electric models first helps them stay ahead of regulations while testing what buyers actually want.
FAQ 4. Has the GLB grown in size or is it just marketing talk?
It has genuinely grown. The car is longer, a bit wider and sits on a stretched wheelbase. You feel it most in the rear seats, where space is less of a compromise than before.
FAQ 5. Does the GLB still work as a practical family SUV?
Yes, and that hasn’t changed much. The option of three rows, decent headroom and a usable boot still makes it one of the more sensible Mercedes SUVs if practicality actually matters.
FAQ 6. What stands out inside the cabin now?
The screens. You can’t miss them. The new setup feels more digital and cleaner than before. At the same time, Mercedes seems to have learned from feedback and avoided going fully touch-everything.
FAQ 7. Has Mercedes changed the design too much?
No, and that’s probably intentional. It still looks boxy, upright and recognisably GLB. The updates are mostly in the details rather than the overall shape.
FAQ 8. Will buyers in India see the electric GLB soon?
At least initially, no. The expectation right now is petrol and diesel versions first. Electric models may come later, but that depends on how things evolve locally.
FAQ 9. When should people realistically expect to see it on roads?
Early 2026 is the current window for global deliveries. Some regions may get it sooner, others later, depending on which versions are prioritized.
FAQ 10. Who is this new GLB actually meant for?
It’s for buyers who want a Mercedes badge and modern tech but don’t want something huge. If occasional third-row use, everyday comfort and a premium feel are important, the GLB still fits that role quite well.
