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.

The A-segment is the first category in the passenger car classification system defined by the European Commission. It is used for city cars, the smallest category of passenger cars defined.
