Side-by-Side Specs
| Spec | Kia Niro EV | XPENG G9 |
|---|---|---|
| Compared variant | 64.8 kWh | RWD Long Range |
| Battery (approx.) | ~64.8 kWh | ~92.2 kWh |
| WLTP range (rated) | ~464 km | ~570 km |
| Efficiency (approx.) | ~164 Wh/km | ~192 Wh/km |
| DC fast charging (published) | up to 94 kW | up to 300 kW |
| 10-80% charge time (approx.) | ~41 min | ~20 min |
| Max AC charging | up to 11 kW | up to 11 kW |

Charging Speed
The XPENG G9 has the higher published DC charging figure at 300 kW, which is roughly 219% higher than the Kia Niro EV at 94 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 XPENG G9 is listed at about 20 minutes, which is 21 minutes quicker than the Kia Niro EV at 41 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The XPENG G9 has a WLTP rated range of approximately 570 km, which is roughly 106 km more than the Kia Niro EV at approximately 464 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 Kia Niro EV consumes 164 Wh/km, compared to 192 Wh/km for the XPENG G9. That means the Kia Niro EV 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 XPENG G9 has approximately 92.2 kWh of useable battery , while the Kia Niro EV has approximately 64.8 kWh.
Which One Should You Choose?
If fast charging is your priority, the XPENG G9 has the higher published DC figure (up to 300 kW) and the shorter published charge time at approximately 20 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 Kia Niro EV is the more efficient choice at 164 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the XPENG G9 has a WLTP rated range of approximately 570 km, which is roughly 106 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.
