Alfa Romeo Junior Elettrica vs Toyota bZ4X

Side-by-Side Specs

Charging Speed

The Toyota bZ4X has the higher published DC charging figure at 150 kW, which is roughly 50% higher than the Alfa Romeo Junior Elettrica at 100 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 Alfa Romeo Junior Elettrica is listed at about 27 minutes, which is 2 minutes quicker than the Toyota bZ4X at 29 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Toyota bZ4X has a WLTP rated range of approximately 528 km, which is roughly 128 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 184 Wh/km for the Toyota bZ4X. 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 Toyota bZ4X has approximately 71 kWh of useable battery , while the Alfa Romeo Junior Elettrica has approximately 50.8 kWh.

Which One Should You Choose?

The Toyota bZ4X has the higher published DC figure at up to 150 kW, but the Alfa Romeo Junior Elettrica has the shorter published charge time at approximately 27 minutes versus approximately 29 minutes. On road trips, published stop time matters more than the headline kW number alone.

For AC charging (home wallboxes, workplace chargers, and public street chargers), the Toyota bZ4X supports up to 22 kW, compared to up to 11 kW for the Alfa Romeo Junior Elettrica. In Europe, many public chargers are 22 kW AC, so this difference can matter at those locations if the higher AC figure is fitted on the car you buy.

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 Toyota bZ4X has a WLTP rated range of approximately 528 km, which is roughly 128 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
