Someone over at Citroen has been hitting the absinthe. Well, why not, because Citroen is celebrating its birthday and had the semi-annual Paris auto salon in town to coincide. We'd say they should have stuck with the champagne, but we kinda like this car. Called the Hypnos, it's all business on the outside, and all trippy on the inside.

The exterior looks something like a darker, more versatile version of the GT concept developed by the same company. The interior is something else altogether, and is likely to seem familiar only to those who have gone diving in coral reefs or spent some time in Amsterdam. (If anyone's asking, we fall into the former.) Power is provided by the the HYmotion4 hybrid diesel powertrain PSA rolled out on several show cars, including sister-company Peugeot's Prologue and RC HYmotion4 concepts, which gives the Hypnos green credentials to go with the hippie-inspired design theme. Of course, this falls squarely in the design study category of concept cars (as opposed to the production preview sort), but if this is an indication of where Citroen is headed, overseas customers could be in for a wild ride.
