Performance evaluation with a 6-degree-of-freedom vibration machine

Comprehensive evaluation of the features and performance expected of an automobile.

In 1970, Aisin Seiki became one of the world's first automotive parts manufacturers to construct its own comprehensive proving ground equipped with test tracks. With state-of-the-art facilities and test courses recreating road conditions of all types, we have continued demonstrating and heightening performance and durability. We have performed tests from every conceivable angle, adopting the viewpoints of users, and promptly incorporated the evaluation results back into product development.
As demand for product reliability grows, Aisin Seiki is there every step of the way.
Aisin Seiki is pursuing continuous innovation in the development of next-generation products and effective use by the Group.
