Mercedes-Benz GLC Electric vs XPENG G6

Side-by-Side Specs

Charging Speed

The Mercedes-Benz GLC Electric has the higher published DC charging figure at 330 kW, which is roughly 18% higher than the XPENG G6 at 280 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 XPENG G6 is listed at about 20 minutes, which is 2 minutes quicker than the Mercedes-Benz GLC Electric at 22 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 195 km more than the XPENG G6 at approximately 520 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 XPENG G6 consumes 184 Wh/km, compared to 188 Wh/km for the Mercedes-Benz GLC Electric. That means the XPENG G6 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 XPENG G6 has approximately 80 kWh.

Which One Should You Choose?

The Mercedes-Benz GLC Electric has the higher published DC figure at up to 330 kW, but the XPENG G6 has the shorter published charge time at approximately 20 minutes versus approximately 22 minutes. On 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 XPENG G6. 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 XPENG G6 is the more efficient choice at 184 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 195 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
