Hypnos by Citroën



French car manufacturer Citroën have designed Hypnos, a diesel-electric hybrid 4x4 concept car, which was awarded concept car of the year by British motoring magazine Autocar last month.


The 4.9m car features rear hinged back doors and an offset seating arrangement with seats upholstered using "prism-shaped components".


A camera installed in the ceiling monitors the driver's facial expressions and alters the cabin's lighting and smell according to their mood.


The British designer of Hypnos' interior, Leighanne Earley, won the Autocar award for Automotive Leader of the Future. The design was shown at the Paris Motor Show in October.


The following is from Citroën:


Citroën has released more details about the spectacular Hypnos concept as the car makes its world premiere at the prestigious Paris Motor Show.


Beautifully proportioned and boldly styled, Hypnos is a true hybrid in both its technology and appearance. The elegant and distinctive crossover vehicle combines the styling cues of a sporty coupé, the serene comfort of a saloon and the practical space of an SUV. At the same time Hypnos is powered by Citroën’s all-new hybrid drivetrain, HYmotion4, marrying dynamic performance with solid green credentials to give 60+mpg economy despite its 200 horsepower.


Citroën’s Hypnos presents an exciting vision for the future of luxury vehicles with innovative and intelligent technology such as a face-recognition system that adjusts the cabin environment to its occupant’s emotions, massaging seats, thermo-sensitive ambient lighting, a faceless clock and diamond-shaped instrument clusters.


Eye-catchingly proportioned at 4.90m long, 2.17m wide and 1.58m high, Hypnos’ exterior design is characterised by a tautly drawn bonnet line, raised waistline and pronounced wheel arches that house generous 22-inch wheels - a hint at the concept’s sophisticated muscle power.


The deep radiant grey of the bodywork, which varies in intensity under different light environments, has an elegant and prestigious sheen, befitting the Hypnos’ luxury interior. A ‘pillarless’ roof, appears to ‘float’ suggesting flowing interior space. Rear hinged back doors provide easy entry into the cars enchanting interior, whilst a cargo tailgate gives unrestricted access to the boot, adding practical functionality to underline Hypnos’ SUV characteristics.


Stepping inside the cabin, passengers are welcomed into an interior embodying the magical qualities of the concept car and begin an unforgettable sensory adventure. The shimmering interior is adorned with premium materials such as leather and brushed aluminium, helping to make the Hypnos’ cabin an environment of exceptional refinement and comfort. The rainbow hues, seen throughout the interior, showcase Citroën’s creative flair and daring originality – the unconventional application of bright, vibrant colours in an executive vehicle.


The four morphologically-sculpted seats are made up of prism-shaped components and can be inflated and deflated to give occupants upper and lower back massages. The body-hugging seats are positioned either side of a unique central console offering occupants an astonishing amount of personal space, and arranged in a helix configuration that inspires images of a DNA strand – reflecting the Hypnos’ design focus on human values.


Passengers can also customise their own space using the pivotal blades of the central helix-shaped console, which includes a range of controls such as the air-conditioning settings.


Hypnos showcases Citroën’s commitment to making technology more accessible and interactive with a raft of innovative features throughout the cabin including colour therapy for passengers.


The driver’s instrument cluster is seen through diamond-like prisms, mounted in metal, with each facet displaying different information. A touch screen is also incorporated into the middle of the console, and air-vents gently diffuse halos of ambient light which varies according to temperature.


A ceiling-mounted camera films the driver’s face and regularly measures anthropometric data to gauge emotions and automatically adjusts the cabin lighting and fragrance accordingly for a more bespoke relaxing experience behind the wheel.


Hypnos also features a strikingly original onboard clock designed by the artist Michel Serviteur. The innovative timepiece, which has no needles or digital display, changes colour depending on the light at different times of the day and emits a succession of rhythmic colour pulses like a breathing organism.

Hypnos confirms Citroën’s respect for the environment with its all-new HYmotion4 diesel hybrid drivetrain. The 4-wheel drive system combines a powerful 200bhp 2.0 HDi DPFS engine and an intelligent 6-speed EGS (Electronic Gearbox System). With the engine driving the front wheels and an axle-mounted electric motor driving the rear wheels, this simple but effective solution shows a possible way ahead for affordable hybrid technology, in line with Citroën thinking.

Capable of a 0-60mph time of around 9-seconds and silent, exhaust-free driving in ZEV (Zero Emission Vehicle) mode, the Hypnos’ efficient system delivers dynamic green performance and driving pleasure with impressive fuel economy of almost 63mpg on the combined cycle and low CO2 emissions at just 120g/km.

When a burst of acceleration is required, Hypnos’ boost function kicks in to deliver a combination of torque from both the combustion and electric powerplants without increasing fuel consumption.

For safe and accomplished ‘green driving’, Hypnos is equipped with Stop & Start technology. This intelligent system also powers the electric motor when the vehicle is in 4x4 mode. For improved safety in difficult driving conditions Hypnos instinctively switches to four-wheel drive mode when faced with low grip or intense handling.

With the emphasis of the concept being on driving pleasure, Hypnos delivers a smooth and cosseted ride thanks to Citroen’s legendary self-levelling suspension which combines the highest standards of passenger comfort with exceptional road manners.

    Citroen concepts are great – then they go and ruin the production models with oversized logo/headlights. And their adverts suck too

  • future architech

    Wow…..Is tis some kind of fantasy car?

  • romeo

    allucinante. nice car, but i have pain in my head

  • The interior is way ahead of the exterior.

  • münte

    omg…. amazing

  • kudzi


  • Freddy_C

    for the modest cipher of….? :)

  • Mowgli

    i like the colors…

  • it sure could be my fantasy..

  • aluk

    I love it ( especially the interior ), except for the back. Not that “beautifully proportioned” at all.

  • Peter

    Having done the DS is a hard legacy – but when a 50-year old car still looks far more futuristic than this rather unsophisticated SciFi thingy, it would give me a strong headache.

  • Maxence

    The problem with french cars is that the cars aren’t aesthetic. It’s very cliché, heavy shape. obtrusive, not consequent to the last detail, etc etc.
    Working on an exciting 4×4…to go to the supermarket…The designer could be in hell.

  • OLGV.

    maaaaaaaan, it looks great… but I love more the interior than the exterior :P

  • Matt

    Not sure about the rear passengers sitting one in front of the other. It could work for the driver but a bit uncomfortable in the back. Then again who ever has passengers in the back these days.

  • fanatic

    So much is commented on this concept car. Whether is good or bad is individual perception. What is exciting is is really the physical model not really keen at looking the at a 3d renderings. 3d renderings are just visualization… Juz cant wait to see the real stuff!

  • Great car in deed !! great design! great concept
    Suicide doors are back in style
    Why do they call it “Sleep” though?
    Hypnos is the greek word for sleep
    I mean this car is a so colorful, so lively, so lovely, so vibrant,so dynamic, so..not “sleep”!
    If they like to make a connection with dreams they should be referring to
    god Hypnos’ cousin, Morfeas god of dreams
    Nonetheless, It is trully an amazing car, a dream car
    I dream that its design makes through the production line

  • m

    I wonder if this car is safe on impact, given the design of the seat…
    Or if the seats are even comfortable. especially for someone who is driving
    and is not right handed (or left handed). the design of the seating implies that there is a morphological preference to a passenger that is, if not physically at least functionally, not symmetrical.

    also what if you drop your pen or cellphone in this environment?
    could you move the seat to reach under it?

  • try to take a look at mazda concept cars

  • K. Rimane

    when would that be? in a century from now?

  • Nikolay

    mazda cx 7

  • Cam G

    I love it! Some really interesting concepts involved. Citroën are of course well known for their forward thinking development ;)

  • w

    interior & exterior wildly contrast – its not really working for me. Dash cluster is quite nice tho

  • On second thought.

    You know, because what we all really want is for everyone to have a mind-bending driving experience at highway speeds .

    Kind of a misplaced theme.

    …why didn’t you just throw a tie-dye t-shirt and some mushrooms into a 2CV? Cheaper.

  • KWilson

    In answer to PaCh, they call it sleep because it’s meant for those on LSD!

  • majestictopaz

    the live concept looks much better, the renders dont do it justice

  • AZM

    Citroen concepts are amazing but when they turn them into reality,they are below normal.

  • Fitsum E.

    soooooooooooooo Elegant ! exterior
    Not a serious interior…may be the colors!!
    But I like its sci-fi interior!!!

  • Look, all the colors of the homo rainbow! In a car!

  • Mr Citreon. Externally your design is fantastic.Go steady on the interior though and gas masks if the driver is ever taken to looking constipated.
    A thought monsier/madam/madmoiselles, The 2cv was a marvel and still is to so many of us and Nissan and Crysler have shown this with the S-Cargo and CCV so please make a modern re-vamp before i give in and buy a Fiat 500.
    Incidentally the 2cv is much re-cycled in the kit-car scene and mine is a Pembleton Brooklands.
    I even re-cycled a BMW motorcycle engine for it and others use Motto-Guzzis`
    A new 2009 2cv…..ahh heaven.
