GLB estimated average
These curves are aggregated, owner-reported degradation data — not official manufacturer figures. Your own result above is the number that matters.
Wh/mi or Wh/km
On the MBUX display, navigate to "Vehicle" → "EQ" → "Energy Flow" (or "Consumption"). Average consumption in kWh/100 km or Wh/mi is displayed. On models with the MBUX Hyperscreen, swipe to the energy consumption widget.
Estimated Range
Estimated range is shown on the instrument cluster (digital display) and in the MBUX "EQ" → "Range" section, which also shows range by driving mode.
Battery Percentage
Battery percentage is displayed on the instrument cluster next to the range, on the MBUX home screen, and in the EQ menu.

About the Mercedes-Benz GLB
The all-electric Mercedes-Benz GLB is one of the first models to use the brand's new MMA (Mercedes Modular Architecture) platform, purpose-built for compact electric vehicles. With an 85 kWh NMC battery and up to 250 kW DC fast charging, it represents a significant step forward from the older EQA and EQB models it effectively replaces.
The MMA platform brings 800V-class architecture with improved charging speeds — a 10–80% rapid charge takes around 23 minutes, putting it on par with Hyundai and Kia's best. WLTP range of up to 350 miles is a major improvement over the previous generation, with real-world figures expected around 240–290 miles.
The compact SUV body style retains the boxy, practical shape of the combustion GLB. Interior technology takes a leap forward with the latest MBUX system and a streamlined digital cockpit. Expect the usual Mercedes refinement with meaningfully improved electric-specific capabilities thanks to the new platform.
What the press thinks
Early impressions of the electric GLB praise the leap in charging speed and range over the older EQA/EQB. The MMA platform is seen as a genuine competitor to Hyundai-Kia's E-GMP. Reviewers note that the compact dimensions may limit boot space compared to larger rivals, but the premium feel and improved efficiency are clear strengths.
