EPA finds 2012 fuel economy was highest ever, 23.8 mpg

The average fuel economy for a new car in the US made a record single-year jump, according to new data from the US Environmental Protection Agency. Fleetwide fuel economy rose a record 1.4 miles per gallon to an all-time high of 23.8 mpg, the EPA says. During the past five years, average new-vehicle fuel economy went up 16 percent while emissions decreased 13 percent. Check out the EPA's press release below and find further information here.

The numbers reflect the fact that the number of US hybrid and diesel models has doubled in the last five years, thanks to automakers expanding their line-ups. Last year, alt-fuel vehicle sales jumped 63 percent to more than 540,000 vehicles, while plug-in vehicle sales roughly tripled to about 50,000 vehicles.

The EPA report echoes similar findings from the University of Michigan Transportation Research Institute (UMTRI), which earlier this year said fleetwide fuel-economy advanced 1.3 miles per gallon to a record 23.8 MPG. And UMTRI said in a separate report early last month that January's average new-vehicle fuel economy continued to increase to a monthly record of 24.5 miles per gallon.

David Friedman, the senior engineer and deputy director of the Union of Concerned Scientists' Clean Vehicles program, said in a statement that the progress is good, but more needs to be done. "With high gas prices the new norm, the average model year 2011 vehicle will cost its owners almost as much to fill up over its lifetime as it did to purchase it," he said. "Consumers need more options to shield themselves from the high cost of gasoline."
