Side-by-Side Specs
| Spec | Alpine A390 | Mercedes-Benz EQB |
|---|---|---|
| Battery (approx.) | ~89 kWh | ~70.5 kWh |
| WLTP range (rated) | ~550 km | ~536 km |
| Efficiency (approx.) | ~189 Wh/km | ~170 Wh/km |
| Max DC charging | up to 200 kW | up to 102 kW |
| 10-80% charge time (approx.) | ~27 min | ~35 min |
| Max AC charging | up to 22 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Alpine A390 has a peak DC charging speed of 200 kW, which is roughly 96% faster than the Mercedes-Benz EQB at 102 kW. In practice, peak speed 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 10-80% charge (the most common DC fast charging scenario), the Alpine A390 finishes in about 27 minutes, which is 8 minutes quicker than the Mercedes-Benz EQB at 35 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Alpine A390 has a WLTP rated range of approximately 550 km, which is roughly 14 km more than 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 189 Wh/km for the Alpine A390. 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 Alpine A390 has approximately 89 kWh of useable battery , while the Mercedes-Benz EQB has approximately 70.5 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the Alpine A390 wins on both peak power (up to 200 kW) and time at the plug (approximately 27 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the Alpine A390 supports up to 22 kW, compared to 11 kW for the Mercedes-Benz EQB. In Europe, many public chargers are 22 kW AC, so this difference can mean charging roughly twice as fast at those locations.
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.
For maximum range between charges, the Alpine A390 has a WLTP rated range of approximately 550 km, which is roughly 14 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

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.
