1992年5月,在意大利汽车城都灵市举办的第64届国际汽车博览会上,以“汽车与环境”为主题,展出了世界各大汽车公司最新研制的样车,其中最引人注目的各种无空气和噪音污染的新型电动汽车。从所展出的样车及技术显示,各大汽车公司不宣而战,展开了电动汽车技术及未来市场大竞争。法国预测,到21世纪初,欧洲市场的电动轿车将达25万辆。日本在为10年内成为最先进的电动汽车技术及生产大国而巨额投资。不言而喻,电动汽车必将替代汽油汽车而充当21世纪交通工具的主角。随着汽车数量猛增,废气和噪音已成为现代城市最大的污染源之一。虽然许多汽车采用了无铅汽油、节油装置和消声器 May 1992, at the 64th International Auto Expo held in Turin, Italy, the auto city, with the theme of “Automobile and Environment”, exhibited the newly developed prototype cars of the world’s major auto companies, the most cited Focus on a variety of non-air and noise pollution of new electric vehicles. From the exhibited prototype and technology show, the major auto companies do not declare war, launched the electric car technology and future market competition. France predicts that by the early 21st century there will be 250,000 electric cars in the European market. Japan is investing heavily in becoming the most advanced electric vehicle technology and manufacturing powerhouse in 10 years. It goes without saying that electric vehicles will replace gasoline vehicles and act as the protagonist of transport in the 21st century. As car numbers have soared, emissions and noise have become one of the largest sources of pollution in modern cities. Although many cars use unleaded petrol, fuel-efficient devices and mufflers
