Side-by-Side Specs
| Spec | BMW i4 | Polestar 2 |
|---|---|---|
| Compared variant | eDrive40 | Long Range Single Motor (MY21-22) |
| Battery (approx.) | ~81.3 kWh | ~75 kWh |
| WLTP range (rated) | ~613 km | ~551 km |
| Efficiency (approx.) | ~155 Wh/km | ~179 Wh/km |
| DC fast charging (published) | up to 205 kW | up to 149 kW |
| 10-80% charge time (approx.) | ~28 min | ~34 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BMW i4 has the higher published DC charging figure at 205 kW, which is roughly 38% higher than the Polestar 2 at 149 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 i4 is listed at about 28 minutes, which is 6 minutes quicker than the Polestar 2 at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW i4 has a WLTP rated range of approximately 613 km, which is roughly 62 km more than the Polestar 2 at approximately 551 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 i4 consumes 155 Wh/km, compared to 179 Wh/km for the Polestar 2. That means the BMW i4 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 i4 has approximately 81.3 kWh of useable battery , while the Polestar 2 has approximately 75 kWh.
Which One Should You Choose?
If fast charging is your priority, the BMW i4 has the higher published DC figure (up to 205 kW) and the shorter published charge time at approximately 28 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 i4 is the more efficient choice at 155 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW i4 has a WLTP rated range of approximately 613 km, which is roughly 62 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.
