Alfa Romeo Junior Elettrica vs Smart #3

Side-by-Side Specs

Charging Speed

The Smart #3 has a peak DC charging speed of 150 kW, which is roughly 50% 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 1 minutes quicker than the Smart #3 at 28 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Smart #3 has a WLTP rated range of approximately 415 km, which is roughly 15 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 175 Wh/km for the Smart #3. 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 Smart #3 has approximately 62 kWh of useable battery , while the Alfa Romeo Junior Elettrica has approximately 51 kWh.

Which One Should You Choose?

The Smart #3 has the higher peak DC speed at up to 150 kW, but the Alfa Romeo Junior Elettrica actually finishes the 10-80% charge faster at approximately 27 minutes versus approximately 28 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 Smart #3 supports up to 22 kW, compared to 11 kW for the Alfa Romeo Junior Elettrica. 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 Smart #3 has a WLTP rated range of approximately 415 km, which is roughly 15 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
