Quick verdict
The BMW iX has a higher peak charging speed at 148 kW DC, but the BMW iX2 actually finishes the 10-80% charge faster (29 min vs 34 min) thanks to its smaller battery. The BMW iX2 is more efficient at 161 Wh/km. The BMW iX2 offers more WLTP rated range at 470 km.
Side-by-Side Specs
| Spec | BMW iX | BMW iX2 |
|---|---|---|
| Battery (approx.) | ~71 kWh | ~65.2 kWh |
| WLTP range (rated) | ~425 km | ~470 km |
| Efficiency (approx.) | ~197 Wh/km | ~161 Wh/km |
| Max DC charging | up to 148 kW | up to 130 kW |
| 10-80% charge time (approx.) | ~34 min | ~29 min |
| Max AC charging | up to 11 kW | up to 11 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The BMW iX has a peak DC charging speed of 148 kW, which is roughly 14% faster than the BMW iX2 at 130 kW. In practice, peak speed 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 iX2 finishes in about 29 minutes, which is 5 minutes quicker than the BMW iX at 34 minutes. On a road trip, that difference adds up over multiple stops.
Range and Efficiency
The BMW iX2 has a WLTP rated range of approximately 470 km, which is roughly 45 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 iX2 consumes 161 Wh/km, compared to 197 Wh/km for the BMW iX. That means the BMW iX2 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 iX2 has approximately 65.2 kWh of useable battery , while the BMW iX has approximately 71 kWh.
Which One Should You Choose?
The BMW iX has the higher peak DC speed at up to 148 kW, but the BMW iX2 actually finishes the 10-80% charge faster at approximately 29 minutes versus approximately 34 minutes. That is because the BMW iX2 has a smaller battery to fill. On road trips, time at the plug matters more than peak power.
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 BMW iX2 is the more efficient choice at 161 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW iX2 has a WLTP rated range of approximately 470 km, which is roughly 45 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.
