Side-by-Side Specs
| Spec | BYD SEAL U | Kia EV6 |
|---|---|---|
| Compared variant | 87 kWh Design | Long Range 2WD |
| Battery (approx.) | ~87 kWh | ~74 kWh |
| WLTP range (rated) | ~500 km | ~528 km |
| Efficiency (approx.) | ~205 Wh/km | ~180 Wh/km |
| DC fast charging (published) | up to 140 kW | up to 233 kW |
| 10-80% charge time (approx.) | ~34 min | ~17 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Kia EV6 has the higher published DC fast-charging figure at 233 kW, which is roughly 66% higher than the BYD SEAL U at 140 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 10-80% charge (the most common DC fast charging scenario), the Kia EV6 finishes in about 17 minutes, which is 17 minutes quicker than the BYD SEAL U at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Kia EV6 has a WLTP rated range of approximately 528 km, which is roughly 28 km more than the BYD SEAL U at approximately 500 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 EV6 consumes 180 Wh/km, compared to 205 Wh/km for the BYD SEAL U. That means the Kia EV6 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 EV6 has approximately 74 kWh of useable battery , while the BYD SEAL U has approximately 87 kWh.
Which One Should You Choose?
If fast charging is your priority, the Kia EV6 has the higher published DC figure (up to 233 kW) while matching the quickest published 10-80% time at approximately 17 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 EV6 is the more efficient choice at 180 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Kia EV6 has a WLTP rated range of approximately 528 km, which is roughly 28 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.
