Photos: Concept cars at the 2008 Paris Motor Show

Concept cars make up our favorite part of any auto show, and Paris in 2008 has a wide variety on hand. From small city cars to new exotics, we've got photos of them all.

Citroen Hypnos

Hypnos is Citroen's design for an environmentally sound crossover vehicle. Hypnos uses a hybrid system, Citroen's HYmotion4, comprised of a two-liter diesel engine up front and an electric motor on the rear axle. With this system, the car can be driven about two miles under electric power before the diesel kicks in, and gets about 52 mpg.
