Photos: Paris Motor Show 2008 concept cars

Our favourite part of any car show are the concepts, design studies shown off by automakers to test audience reaction. At the 2008 Paris Motor Show, we've caught a wide variety of concept cars demonstrating everything from small, eco-friendly city cars to high-performance exotics. Some of these cars are merely a gleam in their designers' eyes, while others are already being slated for production.

Hypnos is Citroen's design for an environmentally sound crossover vehicle. Hypnos uses a hybrid system, Citroen's HyMotion4, comprised of a 2-litre diesel engine up front and an electric motor on the rear axle. With this system, the car can be driven about 2 miles on electric power before the diesel kicks in, and gets about 52mpg.
