About the Alfa Romeo Junior

The Alfa Romeo Junior is a landmark car for the Italian brand — its first fully electric model. Built on Stellantis's eCMP2 platform shared with the Peugeot e-2008 and Fiat 600e, it brings Alfa's distinctive styling DNA to the compact crossover segment.

The standard model uses a 50.8 kWh NMC battery with 156 bhp, while the hotter Veloce variant bumps power to 240 bhp with a sportier chassis setup. DC charging maxes out at 100 kW, delivering a 10–80% charge in around 35 minutes. WLTP range sits between 205 and 250 miles depending on variant.

Alfa has worked to make the Junior feel more engaging than its platform siblings, with quicker steering, firmer damping, and a lower ride height. The interior features a 10.25-inch infotainment screen and the brand's signature telescopic column. It faces stiff competition from the Volvo EX30, but few rivals match its visual drama.

What the press thinks

The press has praised the Junior's sharp styling and more engaging driving dynamics compared to its Stellantis siblings. Some reviewers note the platform limitations, particularly the 100 kW DC charging speed, but agree that Alfa has done a good job differentiating the car from its corporate cousins.
