Quick verdict
The Polestar 3 has the higher published DC charging figure at 250 kW, but the published charge-time data matters more for road-trip stops. The Kia EV9 is listed at about 22 minutes versus 32 minutes for the Polestar 3. The Polestar 3 is more efficient at approximately 202 Wh/km. The Polestar 3 offers more WLTP rated range at 706 km.
Side-by-Side Specs
| Spec | Kia EV9 | Polestar 3 |
|---|---|---|
| Compared variant | 99.8 kWh RWD | Long Range Single Motor |
| Battery (approx.) | ~96 kWh | ~107 kWh |
| WLTP range (rated) | ~579 km | ~706 km |
| Efficiency (approx.) | ~213 Wh/km | ~202 Wh/km |
| DC fast charging (published) | up to 209 kW | up to 250 kW |
| 10-80% charge time (approx.) | ~22 min | ~32 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Polestar 3 has the higher published DC charging figure at 250 kW, which is roughly 20% higher than the Kia EV9 at 209 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 EV9 is listed at about 22 minutes, which is 10 minutes quicker than the Polestar 3 at 32 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Polestar 3 has a WLTP rated range of approximately 706 km, which is roughly 127 km more than the Kia EV9 at approximately 579 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 Polestar 3 consumes 202 Wh/km, compared to 213 Wh/km for the Kia EV9. That means the Polestar 3 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 Polestar 3 has approximately 107 kWh of useable battery , while the Kia EV9 has approximately 96 kWh.
Which One Should You Choose?
The Polestar 3 has the higher published DC figure at up to 250 kW, but the Kia EV9 has the shorter published charge time at approximately 22 minutes versus approximately 32 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 Polestar 3 is the more efficient choice at 202 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Polestar 3 has a WLTP rated range of approximately 706 km, which is roughly 127 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.
