Cars Must Get 35.7mpg by 2015

Cars will have to get 35.7 miles per gallon by 2015, and trucks will have to get 28.6 under new standards issued by the federal government today. That means a combined average of 31.6mpg, an increase of 25% from current standards, CNN reports. The feds require automakers to meet a combined 35mpg by 2020 under last year's energy bill, and today's standards are a step toward that goal. (More fuel economy standards stories.)
