Smart #5 vs XPENG G9

Side-by-Side Specs

Charging Speed

The XPENG G9 has the higher published DC charging figure at 300 kW, which is roughly 50% higher than the Smart #5 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 XPENG G9 is listed at about 20 minutes, which is 8 minutes quicker than the Smart #5 at 28 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The XPENG G9 has a WLTP rated range of approximately 570 km, which is roughly 20 km more than the Smart #5 at approximately 550 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 G9 consumes 192 Wh/km, compared to 202 Wh/km for the Smart #5. That means the XPENG G9 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 G9 has approximately 92.2 kWh of useable battery , while the Smart #5 has approximately 96 kWh.

Which One Should You Choose?

If fast charging is your priority, the XPENG G9 has the higher published DC figure (up to 300 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.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Smart #5 supports up to 22 kW, compared to up to 11 kW for the XPENG G9. 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 G9 is the more efficient choice at 192 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the XPENG G9 has a WLTP rated range of approximately 570 km, which is roughly 20 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
