PORTLAND — New fuel efficiency and global warming standards for cars and light trucks would save Maine residents $427 million at the gas pump and cut oil use in the state by 179 million gallons per year in 2030, according to an analysis by a group advocating for passage of the standards.

The study by Environment Maine released today said each Maine household would save $745 a year on gasoline in 2030 under the proposed new standards.

The group backs an Obama administration proposal that cars and light trucks achieve an average 60 miles per gallon by 2025.

“This should be a given,” Lee Auto Malls Chairman Adam Lee said in a news release from Environment Maine. “A Prius can go over 50 miles per gallon, and we have electric cars that go over 200 miles on a single charge.”
