BMW iX vs BYD SEALION 7

Side-by-Side Specs

Charging Speed

The BYD SEALION 7 has the higher published DC charging figure at 230 kW, which is roughly 55% higher than the BMW iX at 148 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 BYD SEALION 7 is listed at about 24 minutes, which is 10 minutes quicker than the BMW iX at 34 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The BYD SEALION 7 has a WLTP rated range of approximately 502 km, which is roughly 77 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 BMW iX consumes 194 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the BMW iX 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 BYD SEALION 7 has approximately 91.3 kWh of useable battery , while the BMW iX has approximately 71 kWh.

Which One Should You Choose?

If fast charging is your priority, the BYD SEALION 7 has the higher published DC figure (up to 230 kW) and the shorter published charge time at approximately 24 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 BMW iX supports up to 11 kW (22 kW optional), compared to up to 11 kW for the BYD SEALION 7. 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 BMW iX is the more efficient choice at 194 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the BYD SEALION 7 has a WLTP rated range of approximately 502 km, which is roughly 77 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
