For most of us, what we know about automobiles is what we see on the road. Once in a while we’re treated to news about a concept vehicle that we inevitably fall in love with despite the fact that it will never be mass produced in its concept form.

Discovery Channel documented the entire process of bringing a car to market from design to production. Here it is. We hope you enjoy.
