Charging Speed
The Nissan Ariya has the higher published DC charging figure at 130 kW, which is roughly 27% higher than the Mercedes-Benz EQB at 102 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 EQB is listed at about 35 minutes, which is 13 minutes quicker than the Nissan Ariya at 48 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Nissan Ariya has a WLTP rated range of approximately 536 km, which is comparable to the Mercedes-Benz EQB at approximately 536 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 Mercedes-Benz EQB consumes 170 Wh/km, compared to 185 Wh/km for the Nissan Ariya. That means the Mercedes-Benz EQB 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 Nissan Ariya has approximately 87 kWh of useable battery , while the Mercedes-Benz EQB has approximately 70.5 kWh.
Which One Should You Choose?
The Nissan Ariya has the higher published DC figure at up to 130 kW, but the Mercedes-Benz EQB has the shorter published charge time at approximately 35 minutes versus approximately 48 minutes. On 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 Mercedes-Benz EQB is the more efficient choice at 170 Wh/km. Lower consumption means lower electricity bills over time.
Both have similar WLTP rated range at approximately 536 km. The best choice depends on how you charge, how far you drive, and personal preference.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
