Citroen Hypnos: An cross-over hybrid. image

The new cross-over concept from Citroen features a diesel engine and a rear axle-mounted electric motor.  The result: 4.5 l/100 km and 120 g/km of CO2.

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.

The intelligent design of the Hypnos concept car combines:

  • a 200 bhp (147 kW) 2-litre HDi DPFS diesel engine mated to a six-speed electronic gearbox system, with torque of 420 Nm;
  • an electric motor located on the rear axle developing 50 bhp for 200 Nm of torque.

Hypnos is also equipped with Stop & Start technology that cuts out the engine when the car comes to a halt in urban traffic jams or at red lights. This system also powers the electric motor when the vehicle is in 4×4 mode.  Hypnos accelerates from 0 to 100 kph in 9.4 seconds and takes 31 seconds to travel 1, 000 m from a standing start. In particularly difficult driving conditions, such as a snow-covered uphill road, the driver can select 4×4 mode.
