From the wildest, most absurd supercars only a few oligarch gazillionaires will ever own to dinky econohaulers giving mobility to whole populations, Geneva had it all.

Peugeot Onyx concept [w/Gallery]

Peugeot has previewed its Onyx concept, set to debut at this month's Paris motor show, just days after the first teaser images were released. Very much a supercar in terms of its proportions and form, the Onyx is not the first time Peugeot's previewed super and super-sports cars in concept form, but the Onyx looks a lot more promising than previous efforts, from these photos at least. Conforming to the modern, eco-conscious supercar norm, the Onyx features a hybrid drivetrain - following in the footsteps of the BMW i8, Honda NSX and Jaguar CX-75.  Peugeot's stated aim is to push itself upmarket and become a more premium brand, so the Onyx could be read as a sign that the company feels it needs more of a 'halo' car in order to achieve that aim.
