Returning to the French capital only once every two years, the Paris Motor Show represents a rare opportunity for French automakers to show off what they've got. And
Peugeot hasn't missed a beat, showcasing the striking Onyx supercar concept you see here. The hybrid supercar is powered by a 3.7-liter twin-turbo diesel V8 with 600 horsepower, an 80hp electric motor (whose lithium-ion battery is recharged by recuperated brake energy) and mated to a six-speed sequential transmission.
