Side-by-Side Specs
| Spec | Hyundai IONIQ 9 | Kia EV3 |
|---|---|---|
| Compared variant | Long Range RWD | Long Range |
| Battery (approx.) | ~106 kWh | ~78 kWh |
| WLTP range (rated) | ~620 km | ~605 km |
| Efficiency (approx.) | ~210 Wh/km | ~171 Wh/km |
| DC fast charging (published) | up to 250 kW | up to 135 kW |
| 10-80% charge time (approx.) | ~24 min | ~33 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Hyundai IONIQ 9 has the higher published DC charging figure at 250 kW, which is roughly 85% higher than the Kia EV3 at 135 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 Hyundai IONIQ 9 is listed at about 24 minutes, which is 9 minutes quicker than the Kia EV3 at 33 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Hyundai IONIQ 9 has a WLTP rated range of approximately 620 km, which is roughly 15 km more than the Kia EV3 at approximately 605 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 EV3 consumes 171 Wh/km, compared to 210 Wh/km for the Hyundai IONIQ 9. That means the Kia EV3 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 Hyundai IONIQ 9 has approximately 106 kWh of useable battery , while the Kia EV3 has approximately 78 kWh.
Which One Should You Choose?
If fast charging is your priority, the Hyundai IONIQ 9 has the higher published DC figure (up to 250 kW) and the shorter published charge time at approximately 24 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 EV3 is the more efficient choice at 171 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Hyundai IONIQ 9 has a WLTP rated range of approximately 620 km, which is roughly 15 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.
