Both the GM and Chrysler companies have been important contributors to the world of concept cars. In the 50's and 60's, they pushed the automotive world
into the era of large finned cars and concept cars at that time featured all kinds of body shapes and sizes.
The Chevrolet Corvette has been used in many independent designer Corvette versions. The Corvette exterior symbolized the extreme sports car look and Chevrolet has
won several "best of the year" awards with this car. Often modified by 3rd party designers, the offerings varied from inspired to strange, stylish to wacky, and production intent to pure fantasy.
Concept car versions have resulted in improvements in engine design as well as updates in the design of transmissions and suspension systems. Such improvements have
Chevrolet in its design of other production car models.
Considering many auto manufacturers bring out concept versions of their cars, the Chrysler company ranks as one of the most prolific automobile design companies in the
automotive field. Their concept cars have even included a rocket car that worked but, for some reason, was never brought to full production. Chrysler included concept re-designs
to its Jeep family of vehicles where its standard six-cylinder inline engine has given way to a V6 and has seen the introduction of the Jeep Liberty, Jeep Compass, and Jeep
Patriot to its lineup. Chrysler's minivan fans have seen the intoduction of "sto and go" seats, a concept now being adopted by most other contempory competitors.
