Kia EV6 vs Mercedes-Benz GLC Electric

Side-by-Side Specs

Charging Speed

The Kia EV6 has the higher published DC charging figure at 233 kW, which is roughly 17% higher than the Mercedes-Benz GLC Electric at 200 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 EV6 is listed at about 17 minutes, which is 11 minutes quicker than the Mercedes-Benz GLC Electric at 28 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 585 km, which is roughly 57 km more than the Kia EV6 at approximately 528 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 188 Wh/km for the Mercedes-Benz GLC Electric. 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 Mercedes-Benz GLC Electric has approximately 94 kWh of useable battery , while the Kia EV6 has approximately 74 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) and the shorter published charge time at approximately 17 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 EV6. 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 EV6 is the more efficient choice at 180 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 585 km, which is roughly 57 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
