First Sight: Citroën C4

 The Citroen C4 is a new car that shall be formally unveiled at the Paris Motor Show in September as the replacement for the Xsara that has been quietly competing in the European C-class for six years. The C4 was previewed in Geneva with the C4 Sport (a WRX themed concept car based very closely on the production 3-door C4) and less directly with the C6 Lignage Citroen concept car of Geneva 1999 which introduced many of the new car's exterior and interior design themes on a larger vehicle concept. Sitting between the C3 and C5 in Citroen's range, the C4 platform will also be shared by Citroen's partner Peugeot for the 307 replacement.
