Side-by-Side Specs
| Spec | BYD ATTO 2 | XPENG G6 |
|---|---|---|
| Compared variant | Standard | RWD Long Range |
| Battery (approx.) | ~45.12 kWh | ~80 kWh |
| WLTP range (rated) | ~312 km | ~520 km |
| Efficiency (approx.) | ~184 Wh/km | ~184 Wh/km |
| DC fast charging (published) | up to 65 kW | up to 280 kW |
| 10-80% charge time (approx.) | ~37 min | ~20 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The XPENG G6 has the higher published DC charging figure at 280 kW, which is roughly 331% higher than the BYD ATTO 2 at 65 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 17 minutes quicker than the BYD ATTO 2 at 37 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 208 km more than the BYD ATTO 2 at approximately 312 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 184 Wh/km for the BYD ATTO 2. 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 BYD ATTO 2 has approximately 45.12 kWh.
Which One Should You Choose?
If fast charging is your priority, the XPENG G6 has the higher published DC figure (up to 280 kW) and the shorter published charge time at approximately 20 minutes. For long road trips, published stop time matters more than the headline kW number alone.
Both cars support 11 kW AC charging, so home and workplace charging speeds will be similar.
Both cars have similar efficiency at 184 Wh/km, so daily charging costs should be comparable.
For maximum range between charges, the XPENG G6 has a WLTP rated range of approximately 520 km, which is roughly 208 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.
