The Obama administration is setting tough new gas mileage standards for cars and trucks.
Final rules for fuel economy that are set to be signed Thursday are aimed at getting more miles to the gallon from the next generation of gas-electric hybrids, efficient engines and electric cars.
For 2016 model-year vehicles, fuel efficiency targets are being set at 35.5 miles per gallon combined for cars and trucks, an increase of nearly 10 mpg over current standards.
The Environmental Protection Agency is setting a tailpipe emissions standard, the first rules ever for vehicle greenhouse gas emissions.
President Barack Obama says the new fuel-efficiency requirements
will save 1.8 billion barrels of oil.
