只要将美国舰队的每加仑汽油的航行里程增加1英里，每年就会节省61亿加仑汽油，以今天的价格计算，价值170亿美元。

Simply improving the mileage of the U.S. fleet by one mile per gallon would save 6.1 billion gallons of gas per year, or $17 billion at today's prices.

这将使新福克斯超越原有车型和本田思域(Honda Civic)、丰田卡罗拉(Toyota Corolla)和雪弗兰(Chevrolet)Cobalt等竞争对手。 后三种车型在公路行驶时每加仑汽油的行驶里程为35或36英里。

That would put the new Focus ahead of the older model and competitors such as the Honda Civic, Toyota Corolla and Chevrolet Cobalt, all of which are rated at 35 or 36 mpg on the highway.

因此，在13英里或更短的车程中，普锐斯插电汽车和Volt依靠纯电动每加仑燃油行驶的里程相同：都是零。

So on trips of 13 miles or less, the Prius plug-in and Volt deliver the same all-electric MPG: zero.
