Concept Cars, Japan

A concept vehicle or show vehicle is a car prototype made to showcase a concept, new styling and new technology. They are ten shown at motor shows to gauge customer reaction to new and radical designs which may or may not have a chance being produced.
General Motors designer Harley Earl is generally credited with inventing the concept, or show, car, and did much to popularize it through its traveling Motorama shows the 1950s.
Concept cars never go into production directly; in modern times all would have to undergo many changes before the design is finalized for the sake practicality, safety and cost. A "production-intent" vehicle, as opposed to a concept vehicle, serves this purpose.
