Concerning electric cars, methanol cars, and CNG (Compressed Natural Gas) cars, the paper studies the status of development of each of them, grasps the problems on their wide spread through hearings to users, and makes an estimate. of the number of cars which is the target for the spread for the time being on the condition that their performance is on the present level. The development of more efficient electric batteries and motors is anticipated for electric cars. Methanol cars have a problem on travelling performance that travel distance by one battery charge is not more than about (1/2) of the existing cars, as well as technical problems such as the development of diesel type use engines, durability of parts, etc. CNG cars have a problem on travel distance by one battery charge which is not more than about (1/3) of the existing cars and a problem on the space caused by carrying the fuel bomb. The target number of fuel substitution cars for the spread is estimated at 833,000 cars, 14% of all the cars in Japan. As of 1991, the number of fuel substitution cars introduced is about 1,200 cars only. In order to less n. the gap, it is indispensable to prepare the infrastructure, improve performance and reliability of the cars, and reduce the cost. 12 figs., 68 tabs.
