The C4's design was created by a team that included Donato Coco, Jean Pierre Ploué and Bertrand Rapatel. However, that version was a more domesticated hatchback coupé or five-door.
The car was finally unveiled at the 2004 Paris Motor Show, after being officially launched to retail on September 2, 2004. At the Geneva Motor Show in 2004, a concept from the Citroën line's definitive made-bodied coupé revealed the willingness of the French company to employ it in competition. To cope with the market, Citroën was dedicated and committed to building a new model that would appeal to many customers.
