Kia EV9 vs Smart #3

Side-by-Side Specs

Charging Speed

The Kia EV9 has the higher published DC charging figure at 209 kW, which is roughly 39% higher than the Smart #3 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 6 minutes quicker than the Smart #3 at 28 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Kia EV9 has a WLTP rated range of approximately 579 km, which is roughly 164 km more than the Smart #3 at approximately 415 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 Smart #3 consumes 175 Wh/km, compared to 213 Wh/km for the Kia EV9. That means the Smart #3 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 EV9 has approximately 96 kWh of useable battery , while the Smart #3 has approximately 62 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.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Smart #3 supports up to 22 kW, compared to up to 11 kW for the Kia EV9. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.

If you mostly charge at home or at work and care more about daily driving costs, the Smart #3 is the more efficient choice at 175 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Kia EV9 has a WLTP rated range of approximately 579 km, which is roughly 164 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
