The Citroën Hypnos is a concept mid-size luxury crossover produced by Citroën at the 2008 Paris Motor Show. It has a 5-door SUV body style and is powered by a diesel hybrid drivetrain with a rear axle-mounted electric motor. The car's most distinctive design feature is its interior, with rainbow-coloured, offset seats, and a system which analyzes the driver's face to gauge his state of mind and adjust the cabin lighting and scented air freshener fragrance in consequence.[4][5]
Citroën announced that diesel-hybrid engine would be available in all models by 2015.[6]
The concept car has appeared in several auto shows, including the 2011 Goodwood Festival of Speed.[7]
