Manufacturers that practice platform sharing have the ability to create several models based on the same design, but with different names. domestic manufactures from the 1970s onward, e.g., the Chevrolet Trailblazer, GMC Envoy, Buick Rainier, Saab 9-7X, and Isuzu Ascender.
This leads to the public looking over certain models and cannibalized sales from competing divisions with essentially the same product. The two elements of platforms are constant and non-constant.
A car platform is a shared set of common design, engineering, and production efforts, as well as major components over a number of outwardly distinct models and even types of cars, often from different, but related marques.
It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms.
For example, the Lexus ES is essentially an upgraded and rebadged Toyota Camry.If the non-constant elements are not designed to be easily integrated into the constant elements of the platform, extensive and expensive changes will have to be made in order to make the elements compatible again.Failure to do so negates the purpose of platform sharing in that it increases costs as opposed to reducing them.Platform sharing allows manufacturers to design flexible platforms that can be tailored to a country's specific needs without compromising quality.It also allows for manufacturing standardization and improved logistics.
