What is the Citroën C6?
The C6 was Citroën’s flagship executive saloon, designed for long-distance comfort and a distinctive style. Its sweeping roofline and concave rear window set it apart, while features such as a head-up display and Hydractive suspension reflected Citroën’s tradition of technical innovation in its larger cars.
Citroën presented the C6 in 2005. Its single generation, known as I (X6), ran from 2006 to 2012. The design recalled earlier large Citroëns, including the CX.
