A front end suggesting power and prestige
The elegant, taut lines and harmonious styling of the C6 have a strong and immediate appeal.
Viewed from the front, the C6 conveys an impression of power with its low-slung stance and large bumper featuring an integrated air intake between the two round fog lamps and daytime running lights.
The wide front end is accentuated by the chrome chevrons that extend to the slim headlamps, as on other Citroën vehicles. The originally shaped headlamps provide a link between the bumper, the wings and the long, smooth curved forms of the bonnet. Designed to incorporate the side lights  they extend up onto the wings of the car.
The separation between the headlamps, daytime running lights and fog lamps give the Citroën C6 a piercing, determined gaze.
The shape, parallel lines and contours of the front end reveal strength and nobility, reminding us that the C6 is a unique work of design.

 A flowing, aerodynamic profile
The main features of C6 design are flowing lines, energy, aerodynamics and elegance. The body is characterised by a long front overhang and short rear overhang.
The design and shape of the C6 reflect the emotional appeal of an elegant, dynamic coupé with the proportions and features of an executive limousine.
The attractive, imposing  profile of the C6 is showcased by its generous dimensions –  1.86 m wide, 1.46 m high and 4.91 m long, with a 2.90 m wheelbase.
The size of the cabin, which is placed well back, is determined in part by the long front and rear doors and by the large glazed area, which lets the light flood in. The effect is further enhanced by the windows on the frameless doors – a nod to prestige coupé design.
To ensure a flawless finish, these door windows are adjusted individually at the C6 production site at Rennes. This high-precision operation takes place in two-stages. Before being fitted on the car, the doors are placed on a preparation line for the initial adjustment of the windows. When the doors have been mounted on the car, the windows are adjusted for the second time. This time, the operation is manual to ensure a flawless fit.
The doors underline the overall impression of elegance conveyed by the flowing profile of the C6. The quarter window is partially integrated with the rear door, thus extending the line of the body, and adding a further touch to the car's natural flowing design.
The harmonious design is also expressed in the high, clearly marked waist line – reinforcing the impression of safety – and in the roof line whose contours run the length of the body, to touch the concave window at the rear.
The profile of the C6 alternates taut, radical lines with rounded, more natural shapes. The wings house large-diameter wheels. The proportions and dynamic design of the wheels fill the wheel arches, creating an impression of power and agility allied with strength and endurance.
As a further touch of refinement, the lower body is smartly finished off by a chrome strip that extends to the rear bumper. This original design reflects the pursuit of new styling effects.
