Ferrari is showing off its green with a new concept, high-performance vehicle, the Ferrari FFX Millechili. Yes, it's a hybrid and uses its electric drive train not just to boost power but also to increase efficiency.
What's really exciting about the FFX is that its made of lightweight materials including carbon fiber, plastic, and cardboard.

Eh? Cardboard? Well, apparently so. I'm not sure if this is just to make the prototype easier to build, or if Ferrari really is considering its use in vehicles, but, in any case, using lightweight materials to increase efficiency is extremely necessary.
Additionally, the FFX incorporates an advanced aerodynamic undercarriage system that uses jets of air to keep whirlpools of drag from forming beneath the car.
