The Citroën DS5 was prefigured by the Citroën C-SportLounge, a concept car presented by Citroën in September 2005 at the Frankfurt Motor Show, and designed under Citroën design chief Jean-Pierre Ploué.
The Citroën C-SportLounge inspired the DS 5 in 2011, and it has rear suicide doors, while the production car has the lack of the suicide doors.

Its body has drag coefficient of 0.26 and features an interior design inspired by aeroplane cockpits.
