Abstract
It is difficult to understand the structure of product lineups in the car market as cars can be classified by various physical data, such like body size, engine displacement, or wheelbase. It is also difficult to understand consumer cognition of cars, because perception of such complex products can involve many other factors besides Physical attributes. The objective of this study was to clarify product line-up structure in the car market, and to explore the relationship between the physical attributes of cars and consumer cognition. The results should thus provide guidance for product design and development strategy.
