Compared variants: xDrive40 vs Long Range
Updated April 2026
Data shown is approximate and based on publicly available specifications and real-world estimates. For models with multiple battery versions, this page compares the variants listed above. Actual performance varies with driving conditions, temperature, state of charge, and charger hardware. Always check the manufacturer specification page and your vehicle's manual for official figures.

Quick verdict
The BMW iX has the higher published DC charging figure at 148 kW, but the published charge-time data matters more for road-trip stops. The Kia EV3 is listed at about 33 minutes versus 34 minutes for the BMW iX. The Kia EV3 is more efficient at approximately 171 Wh/km. The Kia EV3 offers more WLTP rated range at 605 km.
Side-by-Side Specs
| Spec | BMW iX | Kia EV3 |
|---|---|---|
| Compared variant | xDrive40 | Long Range |
| Battery (approx.) | ~71 kWh | ~78 kWh |
| WLTP range (rated) | ~425 km | ~605 km |
| Efficiency (approx.) | ~197 Wh/km | ~171 Wh/km |
| DC fast charging (published) | up to 148 kW | up to 135 kW |
| 10-80% charge time (approx.) | ~34 min | ~33 min |
| Max AC charging | up to 11 kW (22 kW optional) | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BMW iX has the higher published DC charging figure at 148 kW, which is roughly 10% 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 Kia EV3 is listed at about 33 minutes, which is 1 minutes quicker than the BMW iX at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Kia EV3 has a WLTP rated range of approximately 605 km, which is roughly 180 km more than the BMW iX at approximately 425 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 197 Wh/km for the BMW iX. 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 Kia EV3 has approximately 78 kWh of useable battery , while the BMW iX has approximately 71 kWh.
Which One Should You Choose?
The BMW iX has the higher published DC figure at up to 148 kW, but the Kia EV3 has the shorter published charge time at approximately 33 minutes versus approximately 34 minutes. On road trips, published stop time matters more than the headline kW number alone.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the BMW iX supports up to 11 kW (22 kW optional), compared to up to 11 kW for the Kia EV3. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.
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 Kia EV3 has a WLTP rated range of approximately 605 km, which is roughly 180 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.
