Side-by-Side Specs
| Spec | Ford Mustang Mach-E | Kia EV9 |
|---|---|---|
| Compared variant | Extended Range RWD | 99.8 kWh RWD |
| Battery (approx.) | ~91 kWh | ~96 kWh |
| WLTP range (rated) | ~600 km | ~579 km |
| Efficiency (approx.) | ~190 Wh/km | ~213 Wh/km |
| DC fast charging (published) | up to 150 kW | up to 209 kW |
| 10-80% charge time (approx.) | ~35 min | ~22 min |
| Max AC charging | up to 11 kW | up to 11 kW |

Charging Speed
The Kia EV9 has the higher published DC charging figure at 209 kW, which is roughly 39% higher than the Ford Mustang Mach-E at 150 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 Kia EV9 is listed at about 22 minutes, which is 13 minutes quicker than the Ford Mustang Mach-E at 35 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The Ford Mustang Mach-E has a WLTP rated range of approximately 600 km, which is roughly 21 km more than the Kia EV9 at approximately 579 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 Ford Mustang Mach-E consumes 190 Wh/km, compared to 213 Wh/km for the Kia EV9. That means the Ford Mustang Mach-E 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 Ford Mustang Mach-E has approximately 91 kWh of useable battery , while the Kia EV9 has approximately 96 kWh.
Which One Should You Choose?
If fast charging is your priority, the Kia EV9 has the higher published DC figure (up to 209 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 Ford Mustang Mach-E is the more efficient choice at 190 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the Ford Mustang Mach-E has a WLTP rated range of approximately 600 km, which is roughly 21 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.
