Smart #5 vs XPENG G6

Side-by-Side Specs

Charging Speed

The XPENG G6 has the higher published DC fast-charging figure at 280 kW, which is roughly 40% 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 10-80% charge (the most common DC fast charging scenario), the XPENG G6 finishes in 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 Smart #5 has a WLTP rated range of approximately 550 km, which is roughly 30 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 202 Wh/km for the Smart #5. 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 Smart #5 has approximately 96 kWh of useable battery , while the XPENG G6 has approximately 80 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) while matching the quickest published 10-80% 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 11 kW for the XPENG G6. In Europe, many public chargers are 22 kW AC, so this difference can mean charging roughly twice as fast at those locations.

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 Smart #5 has a WLTP rated range of approximately 550 km, which is roughly 30 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
