A concept vehicle, show vehicle and a prototype is a car made to showcase new styling and/or new technology. They are often shown at motor shows to gauge customer reaction to new and radical designs which may or may not be mass-produced. General Motors designer Harley Earl is generally credited with inventing the concept car, and did much to popularize it through its traveling Motorama shows of 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 of practicality, safety, regulatory compliance, and cost. A "production-intent" vehicle, as opposed to a concept vehicle, serves this purpose.〔(Chrysler "Jolts" PHEV Race; PHEV Ads; V2Green Acquired ), Sep 24, 2008, CalCars (California Cars Initiative)〕 They are also known as prototype cars, but should not be confused with prototype race cars such as the Le Mans Prototype. == Design == Concept cars are often radical in engine or design. Some use non-traditional, exotic, or expensive materials, ranging from paper to carbon fiber to refined alloys. Others have unique layouts, such as gullwing doors, 3 or 5 (or more) wheels, or special abilities not usually found on cars. Because of these often impractical or unprofitable leanings, many concept cars never get past scale models, or even drawings in computer design. Other more traditional concepts can be developed into fully drivable (operational) vehicles with a working drivetrain and accessories. The state of most concept cars lies somewhere in between and does not represent the final product. A very small proportion of concept cars are functional to any useful extent, some cannot move safely at anything above 10 mph. Inoperative "mock-ups" are usually made of wax, clay, metal, fiberglass, plastic or a combination thereof. If drivable, the drivetrain is often borrowed from a production vehicle from the same company, or may have defects and imperfections in design. They can also be quite refined, such as General Motors' Cadillac Sixteen concept.〔(Cadillac Sixteen ), by Nick Hull, Detroit Auto Show 2003 Highlights, Car Design News, Inc.〕 After a concept car's useful life is over, the cars are usually destroyed. Some survive, however, either in a company's museum or hidden away in storage. One unused but operational concept car that languished for years in the North Hollywood, California shop of car customizer George Barris, Ford Motor Company's "Lincoln Futura" from 1954, received a new lease on life as the Batmobile in the ''Batman'' series that debuted in 1966 on the ABC Television Network. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Concept car」の詳細全文を読む スポンサード リンク
