Automobile parts are made of various materials: metals such as iron, copper, and aluminum, as well as non-metals such as plastics, glass, and rubber. The changes in the materials used in automobile manufacturing are presented by comparing the materials in the Type AA passenger car and those in the current Celcior. The highlight is also placed, on the recycling technology, to protect the limited resource and the global environment.

Changes in the Technological Development

Changes in the Technological Development

Many of the Japanese automobile manufacturers cooperated, with foreign manufacturers, to introduce technology and manufacture under license, after the Second World War. However, Toyota pursued the establishment of domestic technology and completed the first-generation Crown, based on its own planning and development, which matched the domestic conditions of the Japanese at that time. The changes in Toyota’s technological development, built from scratch through trial and error, are displayed.

Changes in Modeling Technology

Changes in Modeling Technology

Modeling is a series of processes, from sketching and drawing to presenting 3-dimensional, reduced or full-scale prototypes. Toyota has continuously devised its own creative measures through trial and error as in the case where a prototype was built, with manually hammered steel sheets, in the beginning. Various modeling techniques are shown by exhibiting a wooden 1:1 scale model and a 1:5 scale clay model of a truck in the 1950s.
