Alpine A390

The Alpine A390 is the brand’s leap into the fast electric crossover arena, wrapping Dieppe’s lightweight ethos in a sleek, coupe-ish body with real everyday usability. If the steering and chassis feel echo the A110, this could be the enthusiast’s family EV—subtle, sharp, and très chic, with enough theatre to make the school run feel like a pit lane exit.
