The average gas mileage of new cars and trucks in the U.S. will have to nearly double by 2025 under regulations that were finalized Tuesday by the Obama administration.
The new rules will require the fleet of new cars and trucks to average 54.5 miles per U.S. gallon (4.3 litres/100 km) in 13 years, up from 28.6 mpg (8.22 l/100 km) at the end of last year.
The regulations will bring dramatic changes to the cars and trucks in U.S. showrooms and drive automakers to introduce new technology to make vehicles cleaner and more efficient.
The Obama administration says the changes will save families more than $1.7 trillion US in fuel costs and bring an average savings of $8,000 over the lifetime of a new vehicle sold in 2025. The standards also are the biggest step the U.S. government has ever taken toward cutting greenhouse gas emissions, Environmental Protection Agency Administrator Lisa Jackson said.
The 54.5 mpg standard came from the Obama administration’s quest to cut carbon dioxide emissions nearly in half by 2025. The gas mileage is what’s needed to make that cut.
