The future of cars is making itself available, 3D printing. The article can be found here. It's a technology that has been around but just right now is increasingly expanding into mainstream. The body of the car which can be made from plastics is simply printed out layer by layer on a machine. This will undoubtedly cut back on production time and in the longer run cut down on costs. Build in lithium-ion batteries within the chassis is another fairly new technology. Combine the two and I'm fairly confident we are looking at a quick and easy way of building a car. If it will be affordable is another question.
