BMW iX3 vs BYD ATTO 3

Side-by-Side Specs

Charging Speed

The BMW iX3 has the higher published DC charging figure at 400 kW, which is roughly 349% higher than the BYD ATTO 3 at 89 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 BMW iX3 is listed at about 21 minutes, which is 17 minutes quicker than the BYD ATTO 3 at 38 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 385 km more than the BYD ATTO 3 at approximately 420 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 BYD ATTO 3 consumes 178 Wh/km, compared to 178 Wh/km for the BMW iX3. That means the BYD ATTO 3 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 BMW iX3 has approximately 108.7 kWh of useable battery , while the BYD ATTO 3 has approximately 60.5 kWh.

Which One Should You Choose?

If fast charging is your priority, the BMW iX3 has the higher published DC figure (up to 400 kW) and the shorter published charge time at approximately 21 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 178 Wh/km, so daily charging costs should be comparable.

For maximum range between charges, the BMW iX3 has a WLTP rated range of approximately 805 km, which is roughly 385 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
