Mercedes-Benz GLB Electric vs Opel Mokka Electric

Side-by-Side Specs

Charging Speed

The Mercedes-Benz GLB Electric has the higher published DC charging figure at 353 kW, which is roughly 253% higher than the Opel Mokka Electric at 100 kW. In practice, that figure only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.

For the published fast-charge window, the Mercedes-Benz GLB Electric is listed at about 18 minutes, which is 12 minutes quicker than the Opel Mokka Electric at 30 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Mercedes-Benz GLB Electric has a WLTP rated range of approximately 631 km, which is roughly 225 km more than the Opel Mokka Electric at approximately 406 km. WLTP is a standardized lab test. Expect your actual range to be lower, varying with speed, weather, terrain, and driving style.

Efficiency matters more than battery size for daily driving costs. The Opel Mokka Electric consumes 178 Wh/km, compared to 183 Wh/km for the Mercedes-Benz GLB Electric. That means the Opel Mokka Electric uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.

A more efficient car does not always mean more range. Battery size plays a role too. The Mercedes-Benz GLB Electric has approximately 85 kWh of useable battery , while the Opel Mokka Electric has approximately 50.8 kWh.

Which One Should You Choose?

If fast charging is your priority, the Mercedes-Benz GLB Electric has the higher published DC figure (up to 353 kW) and the shorter published charge time at approximately 18 minutes. For long road trips, published stop time matters more than the headline kW number alone.

Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.

If you mostly charge at home or at work and care more about daily driving costs, the Opel Mokka Electric is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Mercedes-Benz GLB Electric has a WLTP rated range of approximately 631 km, which is roughly 225 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
