Start with what the Citroën C-Zero is: a 5-door hatchback with electric motor, built from 2010 to 2020, as electrification stopped being an experiment and the crossover took every market. What it meant takes a little longer.
The story
The Citroën C-ZERO is a supermini/city car produced by Citroën and is 100% electric powered. It was developed in collaboration with Mitsubishi Motors Corporation (MMC). Its sister was marketed by Peugeot as the Peugeot iOn. The changes between the cars are the different exterior and interior styling and the price. The C-Zero was sold until 2020, when it was replaced by the Ami.
