10/2/2008 – 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.


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, optimising dynamic performance and traction while delivering impressively low fuel consumption and emissions.

Hypnos’ diesel hybrid technology is designed to respect the environment. This is particularly true in the city in ZEV (Zero Emission Vehicle) mode – an “extended”, completely silent all-electric mode with a range of around 3 km at 50 kph

If the driver keeps a foot on the accelerator pedal, the boost function kicks in to provide the immediate torque required. This function combines the torque of the combustion engine with that of the electric motor to deliver outstanding performance without increasing fuel consumption.



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

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.

Hypnos also innovates by bringing passengers the benefits of colour 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 air-freshener fragrance in consequence.
