Quick verdict
The XPENG G6 charges faster with a peak of 280 kW DC, while the XPENG G6 is more efficient at 184 Wh/km. The Alpine A390 offers more WLTP rated range at 550 km.
Side-by-Side Specs
| Spec | Alpine A390 | XPENG G6 |
|---|---|---|
| Battery (approx.) | ~89 kWh | ~80 kWh |
| WLTP range (rated) | ~550 km | ~520 km |
| Efficiency (approx.) | ~189 Wh/km | ~184 Wh/km |
| Max DC charging | up to 200 kW | up to 280 kW |
| 10-80% charge time (approx.) | ~27 min | ~20 min |
| Max AC charging | up to 22 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The XPENG G6 has a peak DC charging speed of 280 kW, which is roughly 40% faster than the Alpine A390 at 200 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 XPENG G6 finishes in about 20 minutes, which is 7 minutes quicker than the Alpine A390 at 27 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 30 km more than the XPENG G6 at approximately 520 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 XPENG G6 consumes 184 Wh/km, compared to 189 Wh/km for the Alpine A390. That means the XPENG G6 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 XPENG G6 has approximately 80 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the XPENG G6 wins on both peak power (up to 280 kW) and time at the plug (approximately 20 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 XPENG G6. 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 XPENG G6 is the more efficient choice at 184 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 30 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.
