BYD SEALION 7 vs Toyota bZ4X

Side-by-Side Specs

Charging Speed

The BYD SEALION 7 has the higher published DC charging figure at 230 kW, which is roughly 53% higher than the Toyota bZ4X at 150 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 5 minutes quicker than the Toyota bZ4X at 29 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Toyota bZ4X has a WLTP rated range of approximately 528 km, which is roughly 26 km more than the BYD SEALION 7 at approximately 502 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 Toyota bZ4X consumes 153 Wh/km, compared to 208 Wh/km for the BYD SEALION 7. That means the Toyota bZ4X 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 Toyota bZ4X has approximately 71 kWh of useable battery , while the BYD SEALION 7 has approximately 91.3 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 Toyota bZ4X supports up to 22 kW, 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 Toyota bZ4X is the more efficient choice at 153 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Toyota bZ4X has a WLTP rated range of approximately 528 km, which is roughly 26 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
