Carmakers and White House Haggling Over Mileage Rules
"The administration is proposing regulations that will require new American cars and trucks to attain an average of as much as 56.2 miles per gallon by 2025, roughly double the current level. That would require increases in fuel efficiency of nearly 5 percent a year from 2017 to 2025.
The standard would put domestic vehicle fuel efficiency on a par with that in Europe, China and Japan,
The United States has the world’s most lenient vehicle emissions and mileage standards, lagging as much as 10 m.p.g. behind the rest of the world. Europe is expected to reach about 60 m.p.g. by 2020."
