Citroën Hypnos


Citroën is revealing its new concept car, Hypnos, at the 2008 Paris Motor Show. An elegant and distinctive cross-over vehicle, Hypnos explores new avenues in the design of luxury ecological vehicles. Its creative technologies deliver outstanding performance and environmental efficiency, combined with subtle but powerful motoring sensations.

HYmotion4 technology for guaranteed thrills and efficiency

The special hybrid technology used on Hypnos highlights Citroën’s commitment to the environment and shows once again that this strong ecological focus is always accompanied by driving thrills and efficiency.

Feasible from an industrial standpoint, the architecture of the concept car’s HYmotion4 diesel hybrid drivetrain features a rear axle-mounted electric motor. This innovative and particularly simple set-up is a perfect fit with the character of Hypnos, optimizing dynamic performance and traction while delivering impressively low fuel consumption and emissions (4.5 l/100 km and 120 g/km of CO2).

And Citroën has made this advanced hybrid technology even more attractive by giving it the form of a beautifully proportioned and boldly styled concept car.

Spellbinding style

Hypnos’ sleek, flowing body lines and high-set stance atop 22-inch wheels clearly denote a car looking for new driving thrills.

The initial appeal of the exterior styling is confirmed inside. The cabin, with its original colors, makes the technology more human and approachable, as illustrated by the dreamlike clock, colour therapy and body-hugging seats.

Passengers enjoy a powerful sensory experience, verging on the magical.


Hypnos is a hybrid in terms of both technology and styling. The body combines the vitality and elegance of a saloon with the volumes of a cross-over.

Powerful, flowing and expressive, Hypnos’ unique proportions and balance promise a driving experience of outstanding emotion. The concept car’s rear-hinged doors and colour-splashed interior draw onlookers in and make them want to climb aboard.

Premium cabin materials, exceptionally comfortable individual seats and dreamlike in-car technology are designed to set high standards in driving pleasure and passenger comfort.

Innovative and elegant body style

Hypnos exudes exceptional elegance and strength with its dynamic, sculpted body lines that are both taut and fluid.

Hypnos is eye-catchingly proportioned at 4.90 m long, 2.17 m wide and 1.58 m high. From the pronounced wheel arches to the tautly drawn bonnet and raised waistline, all the body lines reflect strong but sophisticated muscle power.

Hypnos also appeals with its vitality, giving the impression of movement even when at rest. The pillarless “floating” roof, suggesting generous interior space, flows purposefully back to the concave rear window so typical of Citroën executive saloons. The feeling of movement is also conveyed by the powerfully sculpted flanks.

Hypnos’ sleek looks are showcased by the deep radiant grey of the bodywork. Varying in intensity according to the light, this color gives Hypnos an elegant and prestigious sheen commensurate with its luxury standing.

The rear-hinged doors on Hypnos make access easier, revealing the vehicle’s prestige interior as if uncovering a jewel. A cargo tailgate at the back gives unrestricted access to the boot. Alongside their aesthetic appeal, these opening systems add to the car’s functionality and underline its identity as a vehicle for long-distance travel.

A luxurious welcome

The ambience inside Hypnos is light years away from a conventional motoring experience. The cabin embodies the magical content of the concept car, making each journey an unforgettable sensory adventure.

The shimmering interior makes a dramatic and eye-catching break with the deep grey bodywork. Onlookers will marvel at the rainbow hues of the cabin. Using these bright colors in the interior of an executive car interior underlines Citroën’s creativity.

Using premium materials such as leather and brushed aluminium, the Marque has produced an exceptionally refined cabin that creates a feeling of comfort and confirms the exceptional nature of Hypnos.

The cabin contains four seats positioned on either side of a central helix in a unique configuration that brings to mind DNA and organic life, reflecting Citroën’s focus on human values.
The long, three-meter wheelbase combined with the original, staggered seat layout gives each passenger an astonishing amount of personal space. Never have the passengers in a vehicle of this size had this much room. Leg room, for example, is practically that of a limousine.

In keeping with executive standards of comfort, passengers can customize their own space using the pivoting blades of the central helix, which include a range of controls, such as the air conditioning settings.

The seats are made up of prism-shaped components that can be inflated and deflated to give occupants upper and lower back massages.

Creative interior design

Citroën is committed to making technology more human, accessible and attractive. Giving fitting physical form to this technology and adding new, almost magical, content was one of the main aims when designing Hypnos.

The instrument cluster in front of the driver is presented through prisms, like a diamond, with each facet displaying driving information. And like a jewel, the cluster is mounted in a metal setting of premium quality. This cluster is the main feature at the front of the cabin, embracing a touch screen in the middle of the console and encompassing air vents on either side of the dashboard.
Using micro-diodes located inside the air-conditioning duct, the air vents gently diffuse halos of soft light, in a color that varies with the chosen temperature.

Hypnos also innovates by bringing passengers the benefits of color therapy. A ceiling-mounted camera films the driver’s face and regularly measures anthropometric data. The system compares these measures with pre-recorded data to gauge the driver’s state of mind and adjusts the cabin lighting and scented airfreshener fragrance in consequence. Travelling in Hypnos is a remarkable experience in relaxation.

Hypnos combines technology with creativity to striking effect with its original onboard clock, designed by the artist Michel Serviteur. Combining advanced technology and sheer poetry, the clock changes colour depending on the light at different times of day. Dispensing with needles and digital read-outs, this dreamlike timepiece emits a succession of rhythmic colour pulses like the breathing of a living being.
