Charging Speed
The BMW iX has the higher published DC charging figure at 148 kW, which is roughly 14% 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 published fast-charge window, the BMW iX is listed at 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 111 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 Nissan Ariya consumes 185 Wh/km, compared to 194 Wh/km for the BMW iX. 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 iX has approximately 71 kWh.
Which One Should You Choose?
If fast charging is your priority, the BMW iX has the higher published DC figure (up to 148 kW) and the shorter published charge time at approximately 34 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.
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 185 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 111 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.

From Finn, engineer: Charging specs alone do not tell the full story. Real-world charging speed depends on battery temperature, state of charge, and the charger itself. These comparisons use manufacturer-published data. Approximate values only.
