Description

In the postwar period, the increase in width of the leading Japanese sedans was influenced by the small vehicle re-classification of the Road Transportation Vehicle Act. However, fuel consumption regulations have not significantly affected the sedan's width. Thus, the primary cause of widening sedans has been the pursuit of solid exterior proportions and expansion of interior space. Changes in proportion of height/width have followed the same trends as those of height/length. The acceptable height/width proportions for users range between 0.81 and 0.87, fluctuating over time. However, there is no eigenvalue for every automobile classification like there is for height/length. There is a contradiction between the continual increase in width and the need to respond to rising oil prices and environmental degradation. We speculate that market share differences between sedans and mini-cars reflect the further decline of sedans.
