Side-by-Side Specs
| Spec | Kia EV4 | Polestar 5 |
|---|---|---|
| Compared variant | Fastback 81.4 kWh | Dual Motor |
| Battery (approx.) | ~78 kWh | ~106 kWh |
| WLTP range (rated) | ~633 km | ~670 km |
| Efficiency (approx.) | ~158 Wh/km | ~183 Wh/km |
| DC fast charging (published) | up to 135 kW | up to 350 kW |
| 10-80% charge time (approx.) | ~33 min | ~22 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Polestar 5 has the higher published DC charging figure at 350 kW, which is roughly 159% higher than the Kia EV4 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 Polestar 5 is listed at about 22 minutes, which is 11 minutes quicker than the Kia EV4 at 33 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Polestar 5 has a WLTP rated range of approximately 670 km, which is roughly 37 km more than the Kia EV4 at approximately 633 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 EV4 consumes 158 Wh/km, compared to 183 Wh/km for the Polestar 5. That means the Kia EV4 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 5 has approximately 106 kWh of useable battery , while the Kia EV4 has approximately 78 kWh.
Which One Should You Choose?
If fast charging is your priority, the Polestar 5 has the higher published DC figure (up to 350 kW) and the shorter published charge time at approximately 22 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 EV4 is the more efficient choice at 158 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Polestar 5 has a WLTP rated range of approximately 670 km, which is roughly 37 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.
