Stricter fuel economy rules to come into effect in the US by 2025 image

New rules requiring cars and light trucks to achieve a combined 54.5 mpg by 2025 will be announced today, according to the Detroit Free Press.

Fuel economy targets that will be announced by the U.S. Department of Transportation and the Environmental Protection Agency (EPA) are inspired by those annunced in July, when the Obama administration, carmakers and the State of California agreed on fuel economy standards for the 2017-2025 period.

More than 100 members of Congress wrote a letter to the White House on Tuesday asking that the deal announced in July is maintained. “These regulations, taken together with the first phase of the standards for model years 2012-16 vehicles, will remove the need for as much as 3.8 million barrels of petroleum per day by 2030. Consumers will save thousands of dollars at the pump for gasoline they will no longer need to buy over the lifetime of their vehicles,” the letter said.

There are also politicians who question the deal. U.S. Representative Darrell Issa said that the agreement lacks public input and technical evidence that the requirements can be met.

Back in July, the deal was described as one of the biggest changes in the auto industry, with rules that require 62 mpg for cars and 44 mpg for light trucks, big vans and SUV, almost doubling the present standards. The current agreement states that cars and light trucks must average 34.1 mpg by 2016. Under the new rules, there will be a 5 percent increase for cars and 3.5 percent for light trucks each year, at least until 2021.
