Abstract
In this paper, we introduced "Quantity assessment of Automobile DfE", which was aimed at being able to reduce environmental impact and improve recycling rates. In order to attain it, we disassembled seven gasoline-powered cars including a minivehicle, a hybrid car, and an electric vehicle, and explored its tendency. As a result of analysis, the following clarified. (1)lf it is a new car, it progresses Aluminum-ization to decrease its weights Therefore, the CO_2 cost per kg at manufacturing stage is becoming high. (2) In the vehicles with same displacement volume, although the environmental impact at the time of manufacture and abandonment is high in new vehicles, when based on a use stage, an environmental side has a merit.(3) When it compares about a different vehicle type, a minivehicle has a merit in respect of environment from other vehicle types.(4) When based on a use stage also in HEV and EV, there is a merit in respect of environment
