Charging Speed
The XPENG G6 has a peak DC charging speed of 280 kW, which is roughly 89% faster than the BMW iX at 148 kW. In practice, peak speed 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 10-80% charge (the most common DC fast charging scenario), the XPENG G6 finishes in about 20 minutes, which is 14 minutes quicker than the BMW iX at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The XPENG G6 has a WLTP rated range of approximately 520 km, which is roughly 95 km more than the BMW iX at approximately 425 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 197 Wh/km for the BMW iX. 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 XPENG G6 has approximately 80 kWh of useable battery , while the BMW iX has approximately 71 kWh.
Which One Should You Choose?
If fast charging speed is your priority, the XPENG G6 wins on both peak power (up to 280 kW) and time at the plug (approximately 20 minutes from 10-80%). For long road trips with multiple charging stops, that faster turnaround makes a real difference.
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 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 XPENG G6 has a WLTP rated range of approximately 520 km, which is roughly 95 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.
