According to the passage, which of the following is INCORRECT? ( )

参考解析：

是非题。根据首段最后That means automakers will need to make internal combustion engines more efficient to comply with new standards.可知汽车制造商需要在未来提高内燃机效率迎合新标准要求，那就说明当前的内燃机效率是不符合新标准要求的，选项A表述正确；根据第二段首句...fuel cells will add to overall efficiency. But only if people can afford them.可知由燃料电池提供动力的汽车价格会更昂贵，选项B表述正确；根据首段And 95% of cars will rely on fossil fuels for at least part of their power.可知选项C表述正确。选项D：如果大家使用混合动力引擎，温室气体排放和污染将会减少。文中并未提及混合动力汽车使用后会给温室气体排放和污染带来的效果，属于无中生有项。故本题正确答案选D。
