The sedan version was introduced as the Citroën C-Triomphe, a mid-size sedan automobile produced from 2006 for the Chinese market by Dongfeng Peugeot-Citroën Automobile, a joint venture between the French PSA Group (Peugeot-Citroën) and the Chinese manufacturer Dongfeng.

This new model range was designed to supplement other Chinese models, such as the Fukang and the Elysée, rather than being a direct replacement.

In April 2007, Citroën announced that the four-door C4 would be built in Argentina.
The Argentinian and Brazilian versions are sold as the C4 Pallas and C4 Sedan in some South American and European markets.

The car is a notchback sedan version of the European C4 model, since the Chinese market prefers traditional three-box sedans over hatchbacks.
It did not keep the designation, however, because in Chinese, the number "4" is unlucky.
The sedan is much larger than the hatchback: its length is 4,770 mm (187.8 in) over the hatchback's 4,260 mm (167.7 in) and its wheelbase measures 2,710 mm (106.7 in) against 2,610 mm (102.8 in) of the hatchback.
This caused the C-Triomphe sedan to be classified in the large family car class.
The C-Triomphe has a number of unique features, such as an integrated air freshener, which allows the driver to choose the scent of the interior.

In 2009, the C-Triomphe was accompanied by the Citroën C-Quatrè, a smaller (length 4,588 mm (180.6 in), wheelbase 2,608 mm (102.7 in)), cheaper, and more fashionably styled sedan version of the C4.
For 2012, Citroën planned a new facelift version of the C-Quatrè sedan to unveil at the Shanghai Motor Show based on the first generation of the European C4.
