Virtual testing: automakers drive to eliminate physical prototypes.
WOULD Y0U DRIVE A CAR whose components have been designed without the aid of physical testing? Actually, you are probably already doing so. The Big Three automotive manufacturers have put years of effort into the testing of virtual assemblies, and for good reason. Global competition has forced them to slash vehicle development time from five years to two, and they're achieving such reductions largely by cutting the number of physical prototypes they have to build for testing.
General Motors calls its program "moving from Road to Lab to Math," emphasizing virtual testing for everything from tracing the path a glass window follows as it opens and closes to ...
