Diesels, Hybrid, Or Electric Which Will Become The NEW Standard When The New CAFE Standards Take Effect?

Calling it "the most important step we've ever taken in reducing our nation's dependence on foreign oil," President Obama announced a proposed new round of fuel economy standards for cars and trucks sold in the United States that would double the average mileage by 2025.

Under the proposed plan, the combined fuel economy of all cars and light trucks sold in 2025 would have to increase to an average of 54.5 miles per gallon, or nearly double the current figure. They'd ramp up to that level over seven years, starting in 2017 when current rules end.

Cars are expected to get an average of 62 mpg in 2025, while trucks should average 44 mpg.
