Kia EV3 vs Mercedes-Benz GLC Electric

Side-by-Side Specs

Charging Speed

The Mercedes-Benz GLC Electric has the higher published DC charging figure at 330 kW, which is roughly 144% higher than the Kia EV3 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 Mercedes-Benz GLC Electric is listed at about 22 minutes, which is 11 minutes quicker than the Kia EV3 at 33 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Mercedes-Benz GLC Electric has a WLTP rated range of approximately 715 km, which is roughly 110 km more than the Kia EV3 at approximately 605 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 EV3 consumes 171 Wh/km, compared to 188 Wh/km for the Mercedes-Benz GLC Electric. That means the Kia EV3 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 Mercedes-Benz GLC Electric has approximately 94 kWh of useable battery , while the Kia EV3 has approximately 78 kWh.

Which One Should You Choose?

If fast charging is your priority, the Mercedes-Benz GLC Electric has the higher published DC figure (up to 330 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 Mercedes-Benz GLC Electric supports up to 11 kW (22 kW optional), compared to up to 11 kW for the Kia EV3. 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 Kia EV3 is the more efficient choice at 171 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Mercedes-Benz GLC Electric has a WLTP rated range of approximately 715 km, which is roughly 110 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
