Updated April 2026
Data shown is approximate and based on publicly available specifications and real-world estimates. For models with multiple battery versions, this page compares the variants listed above. Actual performance varies with driving conditions, temperature, state of charge, and charger hardware. Always check the manufacturer specification page and your vehicle's manual for official figures.

Quick verdict
The Tesla Model Y has the higher published DC fast-charging figure at 250 kW, but the Kia EV9 actually finishes the 10-80% charge just as fast (24 min) in the current published data. The Tesla Model Y is more efficient at approximately 165 Wh/km. The Tesla Model Y offers more WLTP rated range at 586 km.
Side-by-Side Specs
| Spec | Kia EV9 | Tesla Model Y |
|---|---|---|
| Compared variant | 99.8 kWh RWD | Long Range AWD |
| Battery (approx.) | ~96 kWh | ~75 kWh |
| WLTP range (rated) | ~563 km | ~586 km |
| Efficiency (approx.) | ~213 Wh/km | ~165 Wh/km |
| DC fast charging (published) | up to 233 kW | up to 250 kW |
| 10-80% charge time (approx.) | ~24 min | ~27 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Tesla Model Y has the higher published DC fast-charging figure at 250 kW, which is roughly 7% higher than the Kia EV9 at 233 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 EV9 finishes in about 24 minutes, which is 3 minutes quicker than the Tesla Model Y at 27 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Tesla Model Y has a WLTP rated range of approximately 586 km, which is roughly 23 km more than the Kia EV9 at approximately 563 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 Tesla Model Y consumes 165 Wh/km, compared to 213 Wh/km for the Kia EV9. That means the Tesla Model Y 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 Tesla Model Y has approximately 75 kWh of useable battery , while the Kia EV9 has approximately 96 kWh.
Which One Should You Choose?
The Tesla Model Y has the higher published DC figure at up to 250 kW, but the Kia EV9 actually finishes the 10-80% charge faster at approximately 24 minutes versus approximately 27 minutes. On 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 Tesla Model Y is the more efficient choice at 165 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Tesla Model Y has a WLTP rated range of approximately 586 km, which is roughly 23 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.
