The Obama administration issued new fuel economy rules on Tuesday that require auto manufacturers to increase the average efficiency of new cars and trucks to 54.5 miles per gallon by 2025.
The new rules, aimed at reducing fuel consumption and cutting greenhouse gas emissions from vehicles, will increase pressure on automakers to develop more alternative-fuel vehicles, like electric and plug-in hybrid cars, as well as improve the mileage of their mass-market models by developing better engines and using lighter materials.
Currently, auto companies are working toward achieving a 35.5 mile-per-gallon average by 2016. The new standards for corporate average fuel economy, or CAFE, won support from most automakers last year during negotiations with federal regulators.
The rules for 2025 represent a victory for environmentalists and advocates of fuel conservation. The administration estimates that Americans will reduce oil consumption by 12 billion barrels of oil because of the higher CAFE standards, issued by the Transportation Department.
“These fuel standards represent the single most important step we’ve ever taken to reduce our dependence on foreign oil,” President Obama said in a statement.
