Concept car

Concept cars are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be produced.

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.

Other more traditional concepts can be developed into fully drivable (operational) vehicles with a working drivetrain and accessories.

A very small proportion of concept cars are functional to any useful extent, and some cannot move safely at speeds above 10 miles per hour (16 km/h).

[citation needed] If drivable, the drivetrain is often borrowed from a production vehicle from the same company or may have defects and imperfections in design.
