Quick verdict
The XPENG G9 has the higher published DC charging figure at 300 kW, but the published charge-time data matters more for road-trip stops. The Kia EV6 is listed at about 17 minutes versus 20 minutes for the XPENG G9. The Kia EV6 is more efficient at approximately 176 Wh/km. The Kia EV6 offers more WLTP rated range at 582 km.
Side-by-Side Specs
| Spec | Kia EV6 | XPENG G9 |
|---|---|---|
| Compared variant | Long Range 2WD | RWD Long Range |
| Battery (approx.) | ~80 kWh | ~92.2 kWh |
| WLTP range (rated) | ~582 km | ~570 km |
| Efficiency (approx.) | ~176 Wh/km | ~192 Wh/km |
| DC fast charging (published) | up to 263 kW | up to 300 kW |
| 10-80% charge time (approx.) | ~17 min | ~20 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The XPENG G9 has the higher published DC charging figure at 300 kW, which is roughly 14% higher than the Kia EV6 at 263 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 Kia EV6 is listed at about 17 minutes, which is 3 minutes quicker than the XPENG G9 at 20 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Kia EV6 has a WLTP rated range of approximately 582 km, which is roughly 12 km more than the XPENG G9 at approximately 570 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 EV6 consumes 176 Wh/km, compared to 192 Wh/km for the XPENG G9. That means the Kia EV6 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 Kia EV6 has approximately 80 kWh of useable battery , while the XPENG G9 has approximately 92.2 kWh.
Which One Should You Choose?
The XPENG G9 has the higher published DC figure at up to 300 kW, but the Kia EV6 has the shorter published charge time at approximately 17 minutes versus approximately 20 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 Kia EV6 is the more efficient choice at 176 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Kia EV6 has a WLTP rated range of approximately 582 km, which is roughly 12 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.
