Quick verdict
The Nissan Ariya has a higher peak charging speed at 130 kW DC, but the Alfa Romeo Junior Elettrica actually finishes the 10-80% charge faster (27 min vs 48 min) thanks to its smaller battery. The Alfa Romeo Junior Elettrica is more efficient at 159 Wh/km. The Nissan Ariya offers more WLTP rated range at 536 km.
Side-by-Side Specs

| Efficiency (approx.) | ~159 Wh/km | ~193 Wh/km |
| Max DC charging | up to 100 kW | up to 130 kW |
| 10-80% charge time (approx.) | ~27 min | ~48 min |
| Max AC charging | up to 11 kW | up to 7.4 kW |
| DC connector | CCS2 | CCS2 |
Charging Speed
The Nissan Ariya has a peak DC charging speed of 130 kW, which is roughly 30% 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 21 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 136 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 193 Wh/km for the Nissan Ariya. 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 Nissan Ariya has approximately 87 kWh of useable battery , while the Alfa Romeo Junior Elettrica has approximately 51 kWh.
Which One Should You Choose?
The Nissan Ariya has the higher peak DC speed at up to 130 kW, but the Alfa Romeo Junior Elettrica actually finishes the 10-80% charge faster at approximately 27 minutes versus approximately 48 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.
For AC charging (home wallboxes, workplace chargers, and public street chargers), the Alfa Romeo Junior Elettrica 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 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 Nissan Ariya has a WLTP rated range of approximately 536 km, which is roughly 136 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.
