In 2011, the EPA took an assessment of the U.S. auto industry. The study concluded that by 2025, average fuel economy across the country should be 54.5 mpg. Yesterday, according to Automotive News, U.S. regulators announced the industry would likely fall short of that projection. Despite “adopting fuel economy technologies at unprecedented rates,” gas prices have kept the demand for utilities and trucks greater than initially predicted.

The 54.5 mpg goal was never intended to be a mandate according to senior administration officials, but more of an estimate on where the industry could be. The government now believes the industry average should fall somewhere between 50 to 52.6 mpg. The report also states automakers won’t need to rely on the sales of hybrids or electric cars;  improvements in standard gasoline engines alone will suffice.
