In 1970, Aisin Seiki became one of the first automotive parts makers in the world to construct its own integrated testing
track and proving ground facility. Since then, we have conducted countless evaluation tests of our automotive parts on
individual test vehicles. Using the latest facilities and equipment, we can reproduce varying road environments from
around the world to verify and pursue the highest standards of safety and durability. Evaluation results are used in
product development to ensure quality and comfort. In this manner, we are accurately responding to the increasing
need for product reliability.
