BMW iX3 vs Nissan Ariya

Side-by-Side Specs

Charging Speed

The BMW iX3 has the higher published DC fast-charging figure at 150 kW, which is roughly 15% higher than the Nissan Ariya at 130 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 BMW iX3 finishes in about 34 minutes, which is 14 minutes quicker than the Nissan Ariya at 48 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Nissan Ariya has a WLTP rated range of approximately 536 km, which is roughly 76 km more than the BMW iX3 at approximately 460 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 Nissan Ariya consumes 193 Wh/km, compared to 206 Wh/km for the BMW iX3. That means the Nissan Ariya 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 Nissan Ariya has approximately 87 kWh of useable battery , while the BMW iX3 has approximately 74 kWh.

Which One Should You Choose?

If fast charging is your priority, the BMW iX3 has the higher published DC figure (up to 150 kW) while matching the quickest published 10-80% time at approximately 34 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 iX3 supports up to 11 kW, compared to 7.4 kW for the Nissan Ariya. 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 Nissan Ariya is the more efficient choice at 193 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Nissan Ariya has a WLTP rated range of approximately 536 km, which is roughly 76 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
