Quick verdict
The Polestar 3 has the higher published DC charging figure at 250 kW, but both cars are listed at about 32 minutes for the published fast-charge window. The Volvo EC40 is more efficient at approximately 162 Wh/km. The Polestar 3 offers more WLTP rated range at 706 km.
Side-by-Side Specs
| Spec | Polestar 3 | Volvo EC40 |
|---|---|---|
| Compared variant | Long Range Single Motor | Single Motor ER |
| Battery (approx.) | ~107 kWh | ~79 kWh |
| WLTP range (rated) | ~706 km | ~583 km |
| Efficiency (approx.) | ~202 Wh/km | ~162 Wh/km |
| DC fast charging (published) | up to 250 kW | up to 207 kW |
| 10-80% charge time (approx.) | ~32 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 21% higher than the Volvo EC40 at 207 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 Volvo EC40 is listed at about 32 minutes, roughly matching the Polestar 3. In this case, the headline kW number should not drive the decision by itself.
Range and Efficiency
The Polestar 3 has a WLTP rated range of approximately 706 km, which is roughly 123 km more than the Volvo EC40 at approximately 583 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 Volvo EC40 consumes 162 Wh/km, compared to 202 Wh/km for the Polestar 3. That means the Volvo EC40 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 Volvo EC40 has approximately 79 kWh.
Which One Should You Choose?
If fast charging is your priority, the Polestar 3 has the higher published DC figure (up to 250 kW), but both cars are listed at approximately 32 minutes for the published fast-charge window. 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 Volvo EC40 is the more efficient choice at 162 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 123 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.
