Quick verdict
The BMW iX has a higher peak charging speed at 148 kW DC, but the Alfa Romeo Junior Elettrica actually finishes the 10-80% charge faster (27 min vs 34 min) thanks to its smaller battery. The Alfa Romeo Junior Elettrica is more efficient at 159 Wh/km. The BMW iX offers more WLTP rated range at 425 km.
Side-by-Side Specs

Charging Speed
The BMW iX has a peak DC charging speed of 148 kW, which is roughly 48% faster than the Alfa Romeo Junior Elettrica at 100 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 Alfa Romeo Junior Elettrica finishes in about 27 minutes, which is 7 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 iX has a WLTP rated range of approximately 425 km, which is roughly 25 km more than the Alfa Romeo Junior Elettrica at approximately 400 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 Alfa Romeo Junior Elettrica consumes 159 Wh/km, compared to 197 Wh/km for the BMW iX. That means the Alfa Romeo Junior Elettrica 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 iX has approximately 71 kWh of useable battery , while the Alfa Romeo Junior Elettrica has approximately 51 kWh.
Which One Should You Choose?
The BMW iX has the higher peak DC speed at up to 148 kW, but the Alfa Romeo Junior Elettrica actually finishes the 10-80% charge faster at approximately 27 minutes versus approximately 34 minutes. That is because the Alfa Romeo Junior Elettrica 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 Alfa Romeo Junior Elettrica is the more efficient choice at 159 Wh/km. Lower consumption means lower electricity bills over time.
For maximum range between charges, the BMW iX has a WLTP rated range of approximately 425 km, which is roughly 25 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.
