美国汽车业和克林顿政府曾宣布联合开发燃料经济性比现行汽车高出两倍的新车型。这种形式的合作在美国历史上尚属首次。开发的首选车型包括电动汽车和混合动力汽车。目前这些新型汽车尚处于研究和试验阶段,因此今后十年内由汽油机和柴油机驱动的轿车和载货车仍将占绝对优势。 技术和工艺的进步也为内燃机轿车的继续存在提供 The U.S. auto industry and the Clinton administration have announced the joint development of new models that are three times more fuel efficient than current vehicles. This is the first time in the history of the United States. Development of preferred models include electric cars and hybrid cars. Currently, these new cars are still in the research and test phase, so gasoline and diesel-powered cars and trucks will still have an absolute advantage over the next decade. Advances in technology and workmanship are also provided for the continued existence of combustion engine cars
