President Barack Obama is expected to announce new national emissions standards for vehicles Tuesday, as well as fuel efficiency standards of 35.5 miles per gallon on average by 2016.
The standards should save billions of barrels of oil but are estimated to cost consumers an extra $1,300 per vehicle.
Administration officials say the plan would be the environmental equivalent of taking 177 million cars off the road. New vehicles would be 30 percent cleaner and more fuel-efficient by the end of the program, they said.
Under the changes, the overall fleet average would have to be 35.5 mpg by 2016, with passenger cars reaching 39 mpg and light trucks hitting 30 mpg.
What do you think of the plan? Are you willing to pay more for more efficient vehicles? Is this a sign that or attitudes toward driving are changing as a nation?
