The Citroën C4 is a small family car/compact car (also classified as a compact crossover SUV since 2020) produced under their Citroën marque, from the French automaker PSA Group, and later Stellantis. It was positioned to be the successor to the Citroën Xsara. The first generation production started in September 2004. In June 2020, the third-generation C4 was released in a form of coupe SUV, abandoning the traditional C-segment hatchback/saloon body style.
