WASHINGTON, April 2 (Reuters) - The U.S. Environmental Protection Agency on Monday rejected an Obama-era plan to make automobiles more fuel efficient in a win for car and oil companies and the latest move by the Trump administration to roll back environmental regulations.

The corporate average fuel economy, or CAFE, standards, were not appropriate and should be revised, the EPA said in a release. EPA Administrator Scott Pruitt said the Obama administration "set the standards too high" and "made assumptions about the standards that didn't comport with reality," but he did not offer any specifics on revising them.

The standards called for roughly doubling by 2025 the average fuel efficiency of new vehicles sold in the United States to about 50 miles (80 km) per gallon, and were seen by proponents as a way to spur innovation in clean technologies.
