The 2nd-generation Mercedes-Benz GLB, officially designated GLB with EQ Technology, has made its global debut, initially as a pure EV. Key highlights: it’s built on Mercedes’ advanced 800V MMA platform, boasts a massive 631 km WLTP-claimed range (for the GLB 250+), supports 320 kW DC ultra-fast charging, offers rare 5- and optional 7-seater configurations, and features the cutting-edge MBUX Superscreen. This post dives into the verified specs, design, unmatched practicality, and what this significant premium compact EV means for the Indian market.

What’s New: Electric Powertrain & 800V Platform Innovation

The new GLB EV replaces the outgoing Mercedes-Benz EQB in the electric SUV line-up, consolidating Mercedes’ compact EV offering.

• Platform & Architecture: It utilizes the modern MMA (Modular Architecture) platform, which features an advanced 800-volt electrical architecture. This architecture is a major upgrade from the EQB’s 400V system, directly enabling faster charging and better efficiency.
• Battery & Range: At launch, the EV uses a large 85 kWh usable battery pack. Mercedes claims a class-leading WLTP-range of up to 631 km for the rear-wheel-drive (RWD) GLB 250+ variant.
• Variants at Launch (Global Specs):
  • GLB 250+ with EQ Technology: Single-motor RWD, producing 268 hp and 335 Nm of torque. (Claimed 0–100 km/h in 7.4 seconds).
  • GLB 350 4MATIC with EQ Technology: Dual-motor AWD, with a combined output of 349 hp and 515 Nm of torque. (Claimed 0–100 km/h in 5.5 seconds, with a WLTP range of up to 614 km).
• Ultra-Fast Charging: Thanks to the 800V system, it supports ultra-fast DC charging up to 320 kW, allowing a charge from 10% to 80% in approximately 22 minutes under optimal conditions.

Key Takeaway for Buyers: The new GLB EV is not just a compact SUV; it’s a mainstream, tech-forward family vehicle that blends everyday usability, genuine flexibility (5- or 7-seater layout), and a modern, high-speed charging EV architecture.

Dimensions & Design: Retained Practicality, Enhanced Space

The new GLB is significantly larger than its predecessor, ensuring improved cabin space.

• Verified Dimensions Increase (vs. outgoing GLB):
  • Lengthier: +98 mm (New length is 4732 mm).
  • Wider: +27 mm (New width is 1861 mm).
  • Longer Wheelbase: +60 mm (New wheelbase is 2889 mm), which is key for increased legroom.
• Exterior Design Cues: It retains the signature boxy, upright proportions for maximum utility while adopting modern EV design. Highlights include: Connected LED light bar across the front and rear, signature star-shaped LED daytime running lights, blanked-off “black panel” grille, and flush retractable door handles.
• Seating & Utility: It is offered in both 5-seat and optional 7-seat configurations, a crucial differentiator in the compact luxury EV segment. EV variants also feature a dedicated 127-litre frunk (front trunk) for added storage.

Interior & Technology: MBUX Superscreen and AI Integration

The cabin of the new GLB reflects Mercedes’ latest high-tech, premium design language.

• MBUX Superscreen Setup: The most notable feature is the optional Superscreen, which integrates a 10.25-inch digital instrument cluster with dual 14-inch central and passenger displays.
• Advanced MBUX: It runs the latest MBUX software, featuring an AI-powered virtual assistant and Google Maps integration for navigation that accurately calculates range based on topography, traffic, and charging availability.
• Comfort Features: The larger dimensions (especially the stretched wheelbase and increased headroom) translate to better comfort. A panoramic glass roof is also confirmed.
• Family Utility: The flexible seating (including the easy-entry third row) and a generous boot volume (540 liters in 5-seater configuration) highlight its family-focused practicality.

Global to India – What to Expect (EV Launch Uncertainty)

What We Know (Verified Facts):

• Global Debut: The 2nd-generation GLB was revealed globally in December 2025, initially as a pure EV.
• EV Replacement: It is officially the successor to the EQB.
• ICE Versions to Follow: Mild-hybrid petrol and diesel versions are scheduled to debut globally later, likely in 2026.

What Remains Uncertain (Critical for Indian Buyers):

• India Launch Timeline: Mercedes-Benz India has not yet confirmed the exact launch date for the 2nd-gen GLB.
• EV vs. ICE for India: The critical unknown is which version will launch first. Recent reports suggest that Mercedes-Benz India may only launch the ICE (petrol/diesel) mild-hybrid versions initially, as volumes for the GLB EV are not expected to be as high as for other upcoming EVs.
• Pricing & Localisation: The new model is expected to arrive as a CBU (Completely Built Unit) import, which will result in a premium price point, likely above the outgoing EQB’s ₹72 lakh (ex-showroom) price. No CKD/localisation benefits are currently planned for the GLB EV.

What Indian Buyers Should Monitor:

• The Power Couple (7-seater + EV): The availability of the 7-seater configuration in the EV model, which is a major draw for the Indian SUV market.
• Real-World Range: How the RWD (631 km WLTP) and AWD (614 km WLTP) variants perform in real-world Indian driving conditions.
• Launch Strategy: Whether Mercedes’ strategy for India is EV-first (like the global launch) or ICE-first (as speculated by some Indian media).

Final Take: A Strong, Versatile EV Contender

The 2026 Mercedes-Benz GLB Electric reveal is a landmark moment. It transforms the compact SUV segment by pairing the highly desirable, boxy GLB practicality with a modern, high-range, and ultra-fast-charging EV platform.

For Indian buyers in the premium segment, the GLB EV looks exceptionally promising on paper due to its family-friendly 7-seat option and class-leading range. However, until Mercedes-Benz India makes an official announcement regarding the EV’s launch, pricing, and assembly strategy, it remains a global-spec benchmark to watch.
