DETROIT — The Obama administration issued on Tuesday the final version of new rules that require automakers to nearly double the average fuel economy of new cars and trucks by 2025.

The standards — which mandate an average fuel economy of 54.5 miles per gallon for the 2025 model year — will increase the pressure on auto manufacturers to step up development of electrified vehicles as well as sharply improve the mileage of their mass-market models through techniques like more efficient engines and lighter car bodies.
