Automobile Drawing

There is a very interesting form of art out there, and that is automobile art. What I mean by this is sketches of automobiles in pencil and pen that are concepts before they are actually cars. This is quite a unique form of art that has been behind the scenes of every car manufacturer since the birth of the Ford Model T. It is interesting that no one ever talks about what it takes to design cars on paper, the very thing manufacurers do before starting production of a vehicle. I don't remember the last conversation an art historian had about the latest car designer, do you? What made light of this for me was a viewing of HorsePower TV in which they did a sort of documentary on a man named Chip Foose, car designer. What is interesting about Chip is that he can create, from imagination, a complete and unique hot rod of his own on paper in a matter of hours. And these drawings are impressive! If anyone has ever been made famous for car design drawings, it is Chip Foose. But what is hard to put a finger on, and what makes it difficult to integrate into an art class, is what type of art this is. It could be realism, it could be modernism. But, it is also probably neither of these because of technical issues. So my question is, what kind of art is this? Certainly it needs to be recognized because these men and women strive to create masterpieces, and do, but hardly get their name heard. Here is Chip's website http://www.chipfoose.com and click "Sketches." Let me know what you think.
