Side-by-Side Specs
| Spec | BMW iX3 | Polestar 4 |
|---|---|---|
| Compared variant | 50 xDrive (Neue Klasse MY26) | Long Range Single Motor |
| Battery (approx.) | ~108.7 kWh | ~94 kWh |
| WLTP range (rated) | ~805 km | ~620 km |
| Efficiency (approx.) | ~178 Wh/km | ~190 Wh/km |
| DC fast charging (published) | up to 400 kW | up to 200 kW |
| 10-80% charge time (approx.) | ~21 min | ~31 min |
| Max AC charging | up to 11 kW | up to 11 kW |

Charging Speed
The BMW iX3 has the higher published DC charging figure at 400 kW, which is roughly 100% higher than the Polestar 4 at 200 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 BMW iX3 is listed at about 21 minutes, which is 10 minutes quicker than the Polestar 4 at 31 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 185 km more than the Polestar 4 at approximately 620 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 BMW iX3 consumes 178 Wh/km, compared to 190 Wh/km for the Polestar 4. That means the BMW iX3 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 BMW iX3 has approximately 108.7 kWh of useable battery , while the Polestar 4 has approximately 94 kWh.
Which One Should You Choose?
If fast charging is your priority, the BMW iX3 has the higher published DC figure (up to 400 kW) and the shorter published charge time at approximately 21 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 BMW iX3 is the more efficient choice at 178 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 185 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.
