At the same time , by the way of analyzing passengers in electric buses and electric cars on human engineering , it acquire the size of eiect fic buses and elect fic cars " room , 1n order to li attain aerodynamicist ' s ev shape , the thesis cite conclusion from recent paper , then summarize optimum value by synthesizing manufacturing technology and human engineering 噪音低：汽车的噪音、振动大小决定于发动机本身和行驶条件。常规汽车和ev相比，虽然因汽车行驶而引起的噪音、振动无显著区别，但电动机比汽油或柴油发动机噪声要小得多，因此在这方面， ev占有绝对的优势。
